Opinion
BROWN, J.—
I. Introduction
Petitioner Jesse James Andrews was convicted of capital murder. (See People v. Andrews (1989) 49 Cal.3d 200 [260 Cal.Rptr. 583, 776 P.2d 285] (Andrews I).) As recounted in Andrews I, the evidence at trial established the following: “On the evening of December 9, 1979, police were summoned to the Los Angeles apartment of Preston Wheeler. There they found the bodies of Wheeler, Patrice Brandon and Ronald Chism. Wheeler had been stabbed in the chest six times and shot in the neck at close range with either a .32- or .357-caliber weapon. His face and head were bruised, and his face had been slashed with a knife. Brandon and Chism had been strangled with wire coat hangers. Their faces were bruised, Chism’s extensively. Brandon’s anus was extremely dilated, bruised, reddened and tom, consistent with the insertion of a penis shortly before her death. There was also redness around the opening of her vagina, and vaginal samples revealed the presence of semen and spermatozoa. All three victims were bound hand and foot.” (Id. at p. 206.)
At trial, the prosecution’s chief witness was Charles Sanders, who testified pursuant to a plea bargain in which he pled guilty to three counts of second degree murder in exchange for a promised sentence of 17 years to life in prison.
Sanders testified that he and petitioner devised a plan to rob Wheeler, a drug dealer. Defendant armed himself with a .357 magnum and gave Sanders a .38- or .32-caliber automatic. On the evening of the murders, they visited their friend, Carol Brooks, who lived in the same apartment building as Wheeler, and then went to Wheeler’s apartment. “In response to their knocking, Wheeler, who apparently knew [petitioner], let them in. Also inside the apartment was a woman (Patrice Brandon), [f] After smoking some marijuana with Wheeler, [petitioner] and Sanders drew their guns. Sanders tied Wheeler and Brandon with belts and socks, put on a pair of gloves, and began to search the apartment for drugs and money. Except for some powder on a saucer which appeared to be cocaine, the search was *1239unsuccessful. [Petitioner] questioned Wheeler, who denied having any drugs or money. Saying he would make Brandon talk, [petitioner] dragged her into the kitchen and closed the door. Sanders remained in the living room with Wheeler.” (Andrews I, supra, 49 Cal.3d at p. 207.)
Sanders heard petitioner hitting Brandon and later heard sounds as though they were having sex. When petitioner came out of the kitchen shortly thereafter, Sanders saw Brandon’s pants around her ankles. (Andrews I, supra, 49 Cal.3d at p. 207.)
“[Petitioner] put his gun in Wheeler’s mouth. He threatened to kill Wheeler and Brandon unless Wheeler revealed the location of the drugs. Wheeler said the ‘dope’ was in the attic, and pointed out a trap door leading up to it. Sanders climbed into the attic. ftf] While in the attic, Sanders heard two shots. When he came down, [petitioner] told him he had shot Wheeler because the latter had tried to jump out the window. Sanders asked if Wheeler was dead. [Petitioner] responded he was ‘standing right up’ on Wheeler when he fired the gun. . . . When Sanders asked about Brandon, [petitioner] replied he had killed her before leaving the kitchen.” (Andrews I, supra, 49 Cal.3d at p. 207.)
While petitioner and Sanders were cleaning up the apartment, Ronald Chism knocked on the door and asked if everything was all right. Petitioner said Wheeler was home and invited him inside. Petitioner “then hit Chism on the head, tied him up, and took him into the bathroom. Sanders saw [petitioner] sitting astride Chism’s back, joining and separating his clenched fists in a tugging motion, apparently strangling Chism.” (Andrews I, supra, 49 Cal.3d at p. 208.) Sanders then saw petitioner go into the kitchen and choke Brandon with a wire clothes hanger. When the two left the apartment, petitioner gave Sanders some money, saying it was all he had found. (Ibid.)
Carol Brooks, whose brother was married to Sanders’s sister, testified that on the night of the murders petitioner told her they were going to Wheeler’s to get some money. Sanders later acknowledged to her his involvement in the crimes; and petitioner told her he had shot Wheeler, taken $300, and had sex with Brandon. (Andrews I, supra, 49 Cal.3d at p. 208.)
Print evidence disclosed the presence of petitioner’s fingerprints on Wheeler’s living room coffee table. A set of left and right palm prints was found on the kitchen floor, the left one about an inch from Brandon’s body. (Andrews I, supra, 49 Cal.3d at p. 208.)
Petitioner did not testify. In an effort to undermine Sanders’s credibility, the defense called two jail inmates whose testimony implied he had lied *1240about petitioner’s involvement in the crimes to minimize his own. (See Andrews I, supra, 49 Cal.3d at p. 209.)
A jury convicted petitioner of the first degree murders of Wheeler, Brandon, and Chism. (Pen. Code, § 187; all undesignated statutory references are to the Penal Code.) As to each minder, it found true special circumstance allegations of prior murder (§ 190.2, subd. (a)(2)), multiple murder (id., subd. (a)(3)), and robbery murder (id., former subd. (a)(17)(i), now subd. (a)(17)(A)). As to Brandon’s murder, it found true the rape-murder special-circumstance allegation. (Id., former subd. (a)(17)(iii), now subd. (a)(17)(C).) The jury also convicted petitioner of rape (former § 261, subds. 2, 3), sodomy by a foreign object (§ 289), and robbery (§ 211). It further found petitioner used a firearm in committing each offense. (§ 12022.5.)
Following the penalty phase evidence, the jury determined the punishment should be death. (Andrews I, supra, 49 Cal.3d at p. 206.) On automatic appeal, this court affirmed the judgment.
Thereafter, petitioner sought a writ of habeas corpus, alleging his trial attorneys (lead counsel Gerald Lenoir, assisted by Halvor Miller) rendered ineffective assistance at the penalty phase. We issued an order to show cause and subsequently appointed the Honorable Jacqueline A. Connor to conduct a reference hearing and take evidence and make findings of fact on the following six questions:
1. What mitigating character and background evidence could have been, but was not, presented by petitioner’s trial attorneys at his penalty trial?
2. What investigative steps by trial counsel, if any, would have led to each such item of information?
3. What investigative steps, if any, did trial counsel take in an effort to gather mitigating evidence to be presented at the penalty phase?
4. What tactical or financial constraints, if any, weighed against the investigation or presentation of mitigating character and background evidence at the penalty phase?
5. What evidence, damaging to petitioner, but not presented by the prosecution at the guilt or penalty trials, would likely have been presented in rebuttal, if petitioner had introduced any such mitigating character and background evidence?
*12416. Did petitioner himself request that either the investigation or the presentation of mitigating evidence at the penalty phase be curtailed in any manner? If so, what specifically did petitioner request?
Having considered the record of the hearing, the referee’s factual findings, and petitioner’s original trial, we conclude petitioner received constitutionally adequate representation, and any inadequacy did not result in prejudice.
II. Penalty Phase Evidence
“At the penalty phase, the prosecution evidence consisted of a stipulation and two exhibits. The parties stipulated that [petitioner] was bom on July 2, 1950, and that he pled guilty in Alabama to the crimes of armed robbery in 1968, escape in 1969, and robbery in 1977. The two exhibits were photographs of two of the victims; they had been excluded from the guilt phase on the ground that they were unduly inflammatory.
“The defense penalty phase evidence, admitted under stipulation, consisted of sworn statements describing the circumstances surrounding [petitioner’s] prior Alabama murder conviction. According to the statements, [petitioner] and a 17-year-old companion, each of whom carried a gun, entered a grocery store and announced a robbery. When the store clerk placed his hand down the front of his apron, [petitioner’s] companion fired three gunshots, killing him.” (Andrews I, supra, 49 Cal.3d at p. 225.)
In his closing argument, Lenoir presented petitioner as an unsophisticated criminal whose crimes—committed many years apart—escalated when planned robberies took unexpected turns. He noted that the Alabama murder occurred when petitioner was only 16 years old and his confederate, Freddie Square, shot the victim when he apparently reached for a weapon. Lenoir also portrayed his conduct as less blameworthy than that of other special circumstance murderers who had been sentenced to life without possibility of parole. In a similar vein, he emphasized that the current murders occurred when petitioner, Sanders, and victims Brandon and Wheeler were all under the influence of narcotics, characterizing this drug usage as partially blurring the lines between guilty offender and innocent victim, unlike the facts in many capital cases. Counsel further noted Sanders received a sentence of 17 years to life imprisonment.
III. Referee’s Report and Petitioner’s Exceptions
A. Findings
The referee provided one-paragraph summaries in response to each question posed in our reference order and also set forth detailed findings on each question.
*12421. What mitigating character and background evidence could have been, but was not, presented by petitioner’s trial attorneys at his penalty trial?
“Trial counsel could have presented evidence of petitioner’s upbringing and childhood, including evidence of his abandonment by his parents from the age of two. The subsequent loss of his grandfather at the age of 11[1] triggered an absence of structure in his life resulting in truancy, delinquency and eventual incarceration at a young age in a segregated brutal institution near Montgomery, Alabama. Further evidence could have been presented on the impact of the Alabama state prison system on petitioner, following a conviction for robbery-murder at the age of 16. This prison experience did not provide petitioner with a basis for rehabilitation but the evidence did show that petitioner adjusted well when the prison structure permitted it. Additionally, witnesses could have been presented to develop mitigation regarding petitioner’s mental health, including a diagnosis of a learning disorder, brain impairment and posttraumatic stress disorder. Finally, petitioner had a large extended family who would have testified to their love and support for petitioner and the impact of his execution on them.”
Based on the testimony of more than 50 witnesses,* 2 the referee explained in her findings that petitioner’s trial attorneys could have presented evidence that petitioner spent his early years in a poor, segregated neighborhood of Mobile, Alabama. His parents were alcoholics who separated soon after his birth. His mother moved to Detroit, Michigan, to better herself when petitioner was two, and his father also moved away when petitioner was young, leaving him in the care of his grandparents and aunt, who raised him in a large family home with his siblings and cousins. Petitioner and his brother were sometimes disciplined by being forced to wear dresses. There was no evidence of abuse; and petitioner apparently had a good relationship with his grandfather, who was described as loving, benevolent, and responsible.3
When petitioner was 9 or 10, his mother returned to the family home with two children by another marriage. About the same time, petitioner’s grandfather, described by the referee as a “pivotal figure” in his life, died. *1243Petitioner, who grieved for his grandfather, felt rejected by his mother and jealous of her new children. He became withdrawn and began skipping school. At the age of 14, he was committed to the Alabama Industrial School for Negro Children, a reform school known as Mt. Meigs, for car theft.
At Mt. Meigs, petitioner encountered appalling conditions. The referee found “he was subjected to beatings, brutality, inadequate conditions and sexual predators. He also participated with the other boys in using inhalants while at the institution. He was rarely visited by family. His passiveness and small physique caused him to be a target of older, tougher boys, from whom no protection or separation was provided.” The evidence also established Mt. Meigs failed to provide any meaningful rehabilitative or educational opportunities.
After petitioner’s release at the age of 16, he became withdrawn and uncommunicative. Over his family’s objections, he began to associate with older, streetwise boys, including Freddie Square, “a more sophisticated young man with manipulative and criminal tendencies.” Within three months, at Square’s instigation, petitioner and Square robbed a grocery store. When they drew guns and announced the robbery, the store clerk placed his hand down the front of his apron. Square fired, killing the clerk. Petitioner had acted as a lookout in the robbery, but played a more active role when he and Square robbed a taxi driver during their getaway, firing three shots at the driver as the latter fled the scene. He was convicted of murder and robbery and introduced to the Alabama State Prison system just before turning 18.4
Petitioner spent the next 10 years in Mobile County Jail and in Kilby, Draper, Atmore, and Holman Prisons in Alabama. Regarding conditions there, the referee heard the accounts of numerous inmates incarcerated with or during the same time as petitioner as well as testimony of noninmates, several of whom had witnessed the conditions firsthand. On this basis, she described conditions in these institutions as “abysmal,” characterized by “severe overcrowding, racial segregation, substandard facilities, no separation of the tougher inmates from younger or smaller inmates, constant violence, the persistent threat of sexual assaults and the constant presence of sexual pressure, the availability and necessity of weapons by all inmates, and degrading conditions in disciplinary modules.” Petitioner not only received *1244beatings but “was also personally subjected to sexual assaults.” At the same time, the referee noted that petitioner was “personally] involve[d] in violence includ[ing] the stabbings of two inmates who had been threatening him.”
In 1976, petitioner was released from prison. He was soon arrested for attempted robbery of a laundry, which “involved taking a young woman hostage at gunpoint and threatening responding police officers.” Petitioner escaped from the Mobile County Jail5 and fled to California, where he found a job and for a short time had a stable relationship with Debra Pickett, with whom he had a child. He then resumed using cocaine and left Pickett. Soon after, he committed the murders in this case. At the reference hearing, petitioner’s son, Dominick, who communicates with petitioner through letters and telephone calls, testified that he loved his father and would be devastated if he were executed.
“Extensive psychiatric testimony was presented in the form of several expert witnesses [including Drs. George Woods, Craig Haney, James Park, Dorcas Bowles, John Irwin, and Myla Young]. They generally described the petitioner as suffering from a learning disorder known as attention deficit disorder, and post traumatic stress disorder. They also described mild to moderate organic brain impairment from a history of drug use and abuse, starting with the inhalants at Mt. Meigs, as well as possibly from a head injury suffered while in prison. These witnesses presented evidence that the aggravating circumstances of the murders and sexual assaults were diminished by an awareness of the context of petitioner’s participation in the instant crime, that his learning disability and the adverse circumstances of his childhood as well as the impact of the Alabama juvenile and adult correctional systems made his behavior understandable and his reincarceration predictable. The added effect of post traumatic stress disorder was presented to mitigate his actions in the Warhurst and laundromat robberies as well as the instant charges. The additional impacts of his experiences in the prison system provide an argument that he was prevented from adjusting to the free world and that his alienation from conventional society led him back to the familiar world of crime.”
Sifting through the “overwhelming]” “minutiae” of this expert testimony, the referee found that “the impact of petitioner’s incarceration history, while a double-edged sword, was compelling, having occurred from an extremely vulnerable and sensitive age. Although there were a number of inconsistencies concerning exactly what petitioner personally experienced, it was undisputed that he was rarely the instigator of violence. On the contrary, the *1245evidence showed that he avoided violence and appeared to adjust well when the structure permitted and that he would continue to do so. His smaller stature made him the target of more violent inmates in virtually every institution in which he was housed. However, when circumstances permitted, he tended to hold positions of responsibility. To the extent that he was involved in prison violence personally, the evidence remains consistent that he was the prey rather than the predator.”
2. What investigative steps by trial counsel, if any, would have led to each item of evidence?
“Trial counsel could have contacted petitioner’s family to develop his background and childhood, including contacting his mother and other relatives either living in the same location or accessible through known family members. Evidence relating to the impact of the juvenile and adult correctional systems could have been developed by obtaining prison records and contacting inmates referenced in those records as well as conducting standard legal research of public records relating to lawsuits involving these institutions. Mental health experts could have been appointed to review the background material and to test petitioner in order to ascertain the viability of psychiatric mitigation.”
In her findings of fact, the referee explained that appellate counsel utilized “standard investigative techniques” to obtain the evidence presented at the reference hearing. She categorized the evidence into three general and partially overlapping areas—the circumstances of petitioner’s upbringing, the impact of the correctional facilities in Alabama and petitioner’s adult experiences, and the psychiatric aspects of petitioner’s history—none of which “called for any extraordinary efforts beyond simple persistence.”
In the referee’s view, petitioner’s attorneys could readily have learned about petitioner’s upbringing from their contact with his mother. Other family members and acquaintances could have been found through her; and many were willing to testily on petitioner’s behalf. Addresses and information were also independently available from public documents; and counsel could have reached numerous individuals familiar with petitioner’s family and upbringing with little effort. “[Gjeneral information regarding schooling issues was available through family members. Many family members and friends continued to live in the Mobile area and others were known to the family . . . .”
“Several areas of inquiry were available relating to petitioner’s experiences in the correctional system in Alabama. . . . Further, ... the ‘word’ *1246had spread that counsel were looking for people who knew petitioner, and several came forward of their own volition.”
“In the area of mental health, there was no significant written history. The references to family members having mental impairments was not particularly impressive. . . . [f ] [Nevertheless,] [r]outine appointment of psychiatric experts would have provided some information to dictate any additional steps that may have been in order.” The referee further found, however, that “[a]ny such inquiry may not necessarily have resulted in the availability of evidence of the diagnoses of organic brain impairment, learning disorders, or of post traumatic stress disorder.  The quality of standardized personality tests was not the same, the knowledge of post traumatic stress disorder was in an infancy stage, and the resulting diagnosis may not necessarily have been favorable to the petitioner.”6
Although “petitioner’s cooperativeness was a significant issue” and he had been more forthcoming with appellate counsel than with his trial counsel, the referee found nonetheless “that essentially all of the information that was presented [by petitioner at the reference hearing] could have been developed through outside sources in the absence of any cooperation from the petitioner.”
3. What investigative steps, if any, did trial counsel take in an effort to gather mitigating evidence to be presented at the penalty phase?
“Trial counsel took two trips to Mobile, searching the court records for petitioner’s priors, and documents relating to his background. On one such trip, they drove around petitioner’s neighborhood searching for relatives or *1247witnesses. They also contacted petitioner’s mother and spent some time interviewing her about petitioner as well as her own history.”
In her factual findings, the referee explained that petitioner’s trial attorneys made only “limited” efforts to gather penalty phase evidence on petitioner’s behalf. The two defense investigators worked solely on the guilt phase; the attorneys themselves did the investigative work on the penalty phase. Counsel did not have petitioner examined by a psychologist, psychiatrist, or any other mental health expert.
Both attorneys traveled to Mobile on February 4, 1983, for one day. There, they spent time searching for records relating to petitioner at the Mobile County courthouse and driving around Mobile in taxis unsuccessfully looking for relatives and “making inquiries.” Miller testified that they were seeking evidence of good character and good deeds, but he could not remember precisely whom or what he and Lenoir were trying to find.7
On counsel’s second trip to Mobile, after petitioner’s first trial resulted in a hung jury, they again visited the county courthouse, where they obtained the information about petitioner’s prior murder conviction. Later that day, they flew to Pensacola, Florida, where they spoke with petitioner’s mother at the airport for an hour and a half or more. “Among other matters discussed, they obtained information about the fact that petitioner had been a slow learner, that he had been raised by his grandparents, and that he started getting into trouble as a teenager. . . . Counsel provided her with their business cards and . . . Mr. Miller specifically recalled that he told her they would contact her if they could convince petitioner to ‘cut us loose in the investigation’ to obtain more information about other family members or any others that may have helped.”
4. What tactical or financial constraints, if any, weighed against the investigation or presentation of mitigating character and background evidence at the penally phase?
“There were no financial constraints affecting the penalty investigation. The tactical constraints were trial counsel’s distaste for the use of inmate witnesses, concern for the consequential development of petitioner’s acts of misconduct while incarcerated as well as the preliminary impression that a ‘poverty-presentation’ lacked viability. Also, the petitioner’s adamant refusal to have his family involved and his threat to disrupt proceedings if his wishes were not honored impacted on counsel’s tactical decisions.”
The referee found “essentially no financial constraints weighing against the investigation or presentation of penalty phase evidence.”
*1248“Regarding tactical constraints, the findings being limited by the absence of Mr. Lenoir’s state of mind, Mr. Miller testified that he felt constrained by the adamancy of petitioner’s opposition to having his family, and in particular his mother, testify at the trial. Mr. Miller was very consistent in his testimony regarding petitioner’s refusal to cooperate in this area, and this position is supported circumstantially by statements made by petitioner as well as testimony from the prosecutor, Ed Ferns. Mr. Miller believed the petitioner when he threatened to be disruptive if these wishes were not accepted. Acceding to these wishes, neither he nor Mr. Lenoir pursued a full investigation of petitioner’s background or family and never learned the names of family members with one or two exceptions.”
In addition, Miller was “not particularly impressed” with the house or neighborhood in which petitioner grew up as providing a basis for mitigation “as it resembled the manner in which counsel had been raised.” “As to the inherent problems of calling prisoners as witnesses, Mr. Miller stated he was not generally impressed with prisoners and did not want to trade ‘good acts’ for ‘bad acts,’ expressing concern about the risk of disclosure of any possible misconduct petitioner may have been personally involved in. In fact, the evidence reflected that petitioner engaged in two stabbings and escaped from custodial facilities on two occasions. From a practical standpoint, relating to Mr. Miller’s reaction to prisoner-witnesses, the inmates who were called did have substantial violent criminal records and these offenses included a substantial number of escapes.
“Common themes at that time in penalty presentations included familial abuse, abandonment and institutional witnesses, although the evidence also noted that penalty trials at that time were not generally lengthy. Post-traumatic stress disorder remained in its incipient stages and was generally not used at this time except relating to Viet Nam veterans, a sharp contrast with current standards.
“The evidence further established that both trial attorneys were severely impeded in their efforts to focus on petitioner by their heavy caseloads, conducting back-to-back capital cases before and after petitioner’s trial.”
5. What evidence, damaging to petitioner, but not presented by the prosecution at the guilt or penalty trials, would likely have been presented in rebuttal, if petitioner had introduced any such mitigating character and background evidence?
“Evidence would have been presented detailing the facts of petitioner’s prior convictions, including the fact that he took hostages in one incident, *1249pointed a gun at the head of a young female then alternately at officers before surrendering, and that he took a dominant role in the robbery of a taxi driver in which he shot at the victim three times. Both of these descriptions counter the portrayal of petitioner as a victim of circumstances. Also, mental health experts would likely have been called to rebut the diagnosis of post-traumatic stress disorder and brain impairment. These experts would further have developed a different diagnosis of anti-social personality disorder and shown petitioner to be of average intelligence. They would have also presented opinions that petitioner’s ability to obtain and maintain employment as well as sustaining a relationship was indicative of normal brain function, and that his activities in the course of the instant murders were not caused by brain damage or intoxication.”
On this point, the referee discussed in particular the reference testimony of Harry Woodall and Tommy Pettis and the prosecution’s mental health experts.
Woodall, the driver of the taxi that petitioner and Freddie Square used as their getaway car in the Alabama grocery store robbery murder, would have testified that petitioner and Square robbed him at gunpoint. While pointing the gun at Woodall, petitioner twice said, “Let’s shoot him.” After they stole Woodall’s wallet, Square ordered Woodall out of the taxi. Three shots were fired at Woodall when he was about 30 feet away; petitioner fired at least two of them.
Mobile Police Officer Pettis testified that on March 23, 1977, he responded to a robbery call. Entering the store from which the call came, he and other officers saw petitioner holding a crying young woman hostage with a cocked gun at her head. He told the officers to leave and “continued to repeat, ‘Someone’s going to get shot, I’m going to shoot.’ ” The officers withdrew. Ultimately, petitioner surrendered to the officers after releasing the young woman and another woman whom he had also held hostage.
Psychologist Dale McNiel disagreed with the testimony of petitioner’s expert, Dr. George Woods, that petitioner suffered from posttraumatic stress disorder. In Dr. McNiel’s view, petitioner suffered from antisocial personality disorder, he was resentful of authority, and his IQ of 93 was within normal limits.
Dr. Reese Jones, a psychiatrist with a specialty in psychoactive drugs, testified that petitioner abused drugs but was not dependent on them. According to Dr. Jones, petitioner’s actions in the year preceding the murder (his employment, his home, and his relationship with Debra Pickett, with *1250whom he had a son) strongly suggested that he had not suffered brain damage. His behavior on the night of the murders showed planning and thought, and it was therefore unlikely that petitioner was under the influence of PCP when he committed the murders.
6. Did petitioner himself request that either the investigation or the presentation of mitigating evidence at the penalty phase be curtailed in any manner? If so, what specifically did petitioner request?
“Petitioner demanded that counsel refrain from contacting or calling his mother or family members as witnesses. Petitioner threatened to disrupt proceedings if his mother were called and he personally addressed the trial judge on this issue. He indicated that he understood the consequences of this position and that it was his choice to proceed in this fashion. There were no other constraints to developing other witnesses or a mental health profile.”
The referee determined that petitioner “adamantly objected to his attorneys approaching his mother and family and having them testify.” She based this finding on petitioner’s own statements at trial, “Miller’s consistent testimony, and the testimony and impressions of the prosecutor Ed Ferns.” This evidence was corroborated by petitioner’s older sister, Carolyn Rivers, and uncontradicted by his mother. When the trial court specifically addressed petitioner regarding his reluctance to have his mother called and explicitly advised that his mother’s testimony could be valuable, petitioner “was very precise in his response, telling the judge that he fully understood and that this was his choice and no one else’s.” Additionally, Lenoir represented on the record at trial that petitioner refused to have his mother called and that “he ‘had his reasons,’ which Mr. Lenoir did not wish to disclose to the court. Apparently Mr. Lenoir knew what these reasons were.” The referee also found that “petitioner went so far as to threaten to disrupt the trial if his mother were called. Counsel acceded to these demands.”
B. Exceptions
Both parties filed exceptions to the report, raising numerous factual questions. Because the determination of all but two of these issues is not material to our resolution of the petition, we need not address them. As for the remaining exceptions, we examine them following the standard that accords deference to factual findings supported by substantial evidence. (People v. Mayfield (1993) 5 Cal.4th 142, 201 [19 Cal.Rptr.2d 836, 852 P.2d 331].)
1. Rebuttal evidence
Petitioner objects to the referee’s finding that the People would have offered rebuttal evidence if the defense had presented the proffered mitigating evidence. The referee rejected the testimony of Prosecutor Ferns that he *1251would not have introduced any rebuttal evidence, with the possible exception of petitioner’s second escape. In the referee’s view, “This position ignores reality .... [T]he time constraints that hampered the prosecution at the time, such as the difficulty Mr. Ferns spoke of in retrieving priors’ [sz'c] information, would have been alleviated by the consumption of trial time in presenting the large number of witnesses contemplated by the defense as shown in these hearings. . . . Had any defense attorney called in excess of fifty witnesses with virtually hundreds of hours of testimony portraying the defendant as a victim of life’s circumstances, these rebuttal witnesses would have undoubtedly been called and presented by the prosecution during a penalty trial.”
We agree with this general assessment of the realities of prosecuting a capital case. Based on the reference hearing testimony, we also conclude the thrust of the referee’s finding—that the prosecutor would have responded to the mitigating evidence now proposed—is supported by substantial evidence and not necessarily inconsistent with Fems’s testimony. It appears Ferns disavowed the likelihood of rebuttal only with respect to prison conditions. He did, however, indicate he would have altered the focus of his closing argument to respond to such evidence. It is also clear from the record that much damaging testimony regarding petitioner’s own violent conduct in prison and other circumstances desensitizing inmates to violence could have, and undoubtedly would have, been elicited on cross-examination. (People v. Mayfield, supra, 5 Cal.4th at p. 208.) Similar inferences can be drawn with respect to the mitigating evidence of family background. While it may be unlikely the prosecutor would have sought to locate rebuttal witnesses in Alabama to contradict evidence of petitioner’s upbringing, the mitigating impact could nevertheless have been undermined on cross-examination and through closing argument, particularly regarding petitioner’s early criminal acts. With respect to mental health rebuttal, the realities of trial surely would have prompted the prosecutor to present expert testimony in contradiction since such witnesses were generally available.
Petitioner counters that if Ferns had found the testimony of Woodall and Pettis so useful, he would have introduced it even without petitioner’s presenting the mitigating evidence. Their testimony, however, did not fit with the focus of the People’s case, which was not petitioner’s past crimes, but the gratuitously brutal circumstances of the current ones. Given the disturbing nature of the facts, the prosecutor had little incentive to parse the details of petitioner’s criminal history. Rather, as was more common in the 1980’s, he emphasized the circumstances of the crimes to persuade the jury death was appropriate. If, however, the jury were to hear details of petitioner’s background in mitigation, the prosecutor would reasonably want to *1252ensure it received a balanced and accurate picture. (See, e.g., People v. Kipp (2001) 26 Cal.4th 1100, 1134 [113 Cal.Rptr.2d 27, 33 P.3d 450].)
Petitioner also asserts the testimony of Woodall and Pettis would have been inadmissible because it did not relate directly to a particular incident or character trait petitioner offered in his defense. (People v. Rodriguez (1986) 42 Cal.3d 730, 792, fn. 24 [230 Cal.Rptr. 667, 726 P.2d 113].) As to Woodall’s testimony, numerous witnesses characterized petitioner as a follower and Freddie Square as a leader in their misconduct. The Woodall shooting demonstrated petitioner could and did take the initiative for violence. While the admissibility of Pettis’s testimony may be somewhat closer, it too shows petitioner’s lack of reluctance to use violence to obtain his ends. We therefore conclude substantial evidence supports the referee’s finding that presenting the mitigating evidence would have opened the door to damaging rebuttal.
2. Petitioner’s curtailment of penalty phase investigation and presentation
Petitioner disputes the referee’s finding that he did not want his family involved. He claims he asked only that his mother not be called as a witness and placed no restrictions whatsoever on the use of other family members. In support of his exception, he cites statements by Lenoir and Miller to the trial court that they were honoring petitioner’s request not to call his mother to testify, without any mention of other relatives. In declarations provided to petitioner’s habeas corpus counsel, Lenoir and Miller both stated only that petitioner had not wanted his mother involved and that they had been unable to find any evidence of good character and good deeds; they said nothing about petitioner’s desire not to have any others in his family contacted.
Even if his attorneys made little effort to discuss with petitioner the possibility of calling family members other than his mother, the referee credited Miller’s testimony that petitioner objected not only to his mother’s involvement, but also to that of any relatives. Giving the referee’s credibility determination the “great weight” to which it is entitled (In re Johnson (1998) 18 Cal.4th 447, 461 [75 Cal.Rptr.2d 878, 957 P.2d 299]), we adopt the referee’s finding that Miller accurately described petitioner’s objection to having family members present mitigating evidence.
IV. Discussion
In a habeas corpus proceeding, the burden of proof lies with the petitioner to prove, by a preponderance of the evidence, facts that establish *1253the invalidity of the judgment under which he is restrained. (In re Cudjo (1999) 20 Cal.4th 673, 687 [85 Cal.Rptr.2d 436, 977 P.2d 66].)
With respect to reference proceedings, “this court independently reviews a referee’s resolution of legal issues and mixed questions of law and fact. [Citation.] Because the referee observes the demeanor of testifying witnesses, and thus has an advantage in assessing their credibility, this court ordinarily gives great weight to the referee’s findings on factual questions, but this deference is arguably inappropriate when the referee’s findings are based entirely on documentary evidence. [Citation.]” (In re Cudjo, supra, 20 Cal.4th at pp. 687-688.)
To prove a claim of ineffective assistance of counsel at the penalty phase trial, the petitioner “must establish that counsel’s performance did not meet an objective standard of reasonableness under prevailing professional norms and that he suffered prejudice thereby. [Citation.] Prejudice is established when ‘ “there is a reasonable probability that, absent the errors [of counsel], the sentencer . . . would have concluded that the balance of aggravating and mitigating circumstances did not warrant death.” [Citations.] As in the guilt phase, reasonable probability is defined as one that undermines confidence in the verdict.’ [Citation.] Alternatively, the petitioner may establish that as a result of counsel’s inadequacy, the prosecution case was not subject to meaningful adversarial testing, thereby raising a presumption that the result is unreliable. [Citation.]” (In re Gay (1998) 19 Cal.4th 771, 790 [80 Cal.Rptr.2d 765, 968 P.2d 476]; see also Strickland v. Washington (1984) 466 U.S. 668, 688, 694 [104 S.Ct. 2052, 2064-2065, 2068, 80 L.Ed.2d 674] (Strickland).)
In measuring counsel’s performance, the United States Supreme Court has cautioned that judicial scrutiny “must be highly deferential. It is all too tempting for a defendant to second-guess counsel’s assistance after conviction or adverse sentence, and it is all too easy for a court, examining counsel’s defense after it has proved unsuccessful, to conclude that a particular act or omission of counsel was unreasonable. [Citation.] A fair assessment of attorney performance requires that every effort be made to eliminate the distorting effects of hindsight, to reconstruct the circumstances of counsel’s challenged conduct, and to evaluate the conduct from counsel’s perspective at the time. Because of the difficulties inherent in making the evaluation, a court must indulge a strong presumption that counsel’s conduct falls within the wide range of reasonable professional assistance; that is, the defendant must overcome the presumption that, under the circumstances, the challenged action ‘might be considered sound trial strategy.’ [Citation.] There are countless ways to provide effective assistance in any given case. *1254Even the best criminal defense attorneys would not defend a particular client in the same way.” (Strickland, supra, 466 U.S. at p. 689 [104 S.Ct. at p. 2065] ; Bell v. Cone (2002) 535 U.S. 685 [122 S.Ct. 1843, 152 L.Ed.2d 914].) The high court has also expressly reaffirmed that the Strickland standard applies to an assessment of counsel’s “failure to adduce mitigating evidence and the waiver of closing argument” with respect to capital sentencing. (Bell v. Cone, at pp. 696-699 [122 S.Ct. at pp. 1851-1852].)
Assessing petitioner’s claim in light of the referee’s findings and these governing principles, we conclude petitioner “has not established that ‘in light of all the circumstances, the identified acts or omissions [of counsel] were outside the wide range of professionally competent assistance.’ [Citation.] He ‘has made no showing that the justice of his sentence was rendered unreliable by a breakdown in the adversary process caused by deficiencies in counsel’s assistance.’ [Citation.]” (Burger v. Kemp (1987) 483 U.S. 776, 795-796 [107 S.Ct. 3114, 3126, 97 L.Ed.2d 638], quoting Strickland, supra, 466 U.S. at pp. 690, 700 [104 S.Ct. at pp. 2065, 2071].)
In Strickland, the Supreme Court specifically addressed counsel’s duty to investigate and made clear courts should not equate effective assistance with exhaustive investigation of potential mitigating evidence: “[S]trategic choices made after less than complete investigation are reasonable precisely to the extent that reasonable professional judgments support the limitations on investigation. In other words, counsel has a duty to make reasonable investigations or to make a reasonable decision that makes particular investigations unnecessary. In any ineffectiveness case, a particular decision not to investigate must be directly assessed for reasonableness in all the circumstances, applying a heavy measure of deference to counsel’s judgments.” (Strickland, supra, 466 U.S. at pp. 690-691 [104 S.Ct. at p. 2066] .) Concomitantly, the high court has recognized that valid strategic choices are possible even without extensive investigative efforts. (See Burger v. Kemp, supra, 483 U.S. at p. 794 [107 S.Ct. at pp. 3125-3126]; see also Wiggins v. Corcoran (4th Cir. 2002) 288 F.3d 629, 640.)
Although the referee found that counsel could have discovered the mitigating evidence presented at the reference hearing with “simple persistence,” it is equally clear petitioner insisted they not involve his family. “As we have repeatedly explained, an attorney representing a defendant at the penalty phase of a capital case is not required to present potentially mitigating evidence over the defendant’s objections. [Citations.]” (People v. Kirkpatrick (1994) 7 Cal.4th 988, 1013 [30 Cal.Rptr.2d 818, 874 P.2d 248].) Nevertheless, counsel visited Alabama and observed petitioner’s childhood *1255home, which they considered unimpressive as a basis for a poverty defense.8 They also contacted petitioner’s mother and sought information about his background. Assuming her revelations were consistent with her reference hearing testimony, they did not depict an excessively abusive or impoverished upbringing. Counsel also had no significant documentation of any mental deficiencies petitioner might suffer.
Moreover, “[t]he reasonableness of counsel’s actions may be determined or substantially influenced by the defendant’s own statements or actions. Counsel’s actions are usually based, quite properly, on informed strategic choices made by the defendant and on information supplied by the defendant. In particular, what investigation decisions are reasonable depends critically on such information.” (Strickland, supra, 466 U.S. at p. 691 [104 S.Ct. at pp. 2066-2067]; Burger v. Kemp, supra, 483 U.S. at p. 795 [107 S.Ct. at p. 2136].)  While counsel were aware petitioner had been incarcerated in the Alabama prison system, he did not inform them of the conditions he endured thereby alerting them to the need for further investigation of possible mitigation. Additionally, whatever mitigating evidence may have been disclosed by pursuing the conditions of incarceration petitioner experienced, counsel knew such evidence would come primarily from the testimony of petitioner’s fellow prisoners, many of whom were hardened criminals with serious felony records. Such testimony also could well open the door to petitioner’s own extensive criminal background.
Thus, counsel’s preliminary investigation did not establish a compelling defense theory, whether considering the areas of family and background, prison conditions, and mental health singularly or collectively.
“The record at the habeas corpus hearing does suggest that [counsel] could well have made a more thorough investigation than [they] did.  Nevertheless, in considering claims of ineffective assistance of counsel, ‘[w]e address not what is prudent or appropriate, but only what is constitutionally compelled.’ [Citation.]” (Burger v. Kemp, supra, 483 U.S. at p. 794 [107 S.Ct. at p. 3126].) “The purpose [of the effective assistance guarantee of the Sixth Amendment] is simply to ensure that criminal defendants receive a fair trial.” (Strickland, supra, 466 U.S. at p. 689 [104 S.Ct. at p. 2065].) Accordingly, the more important focus of our reasonableness inquiry is an assessment of the decision to forgo further investigation in light of the defense strategy counsel ultimately adopted. (See Burger, at pp. 794-795 [107 S.Ct. at pp. 3125-3126]; see also id. at p. 790, fn. 7 [107 S.Ct. at pp. 3123-3124].) *1256Instead of a lengthy presentation of a broad range of witnesses describing in detail various aspects of petitioner’s background—which at the time would have been atypical for a penalty phase defense—Lenoir chose to minimize petitioner’s culpability by circumscribing his background and mitigating his criminal responsibility, portraying him as a follower rather than violently antisocial. (Cf. id. at p. 793 [107 S.Ct. at p. 3125].) He also urged the jury to consider in mitigation the fact that others who had committed more heinous multiple murders had been sentenced to life without possibility of parole and that Sanders received a comparatively lighter sentence.
In adopting this approach, counsel not only presented a reasonable case for sparing petitioner’s life under the circumstances (see Burger v. Kemp, supra, 483 U.S. at p. 795 [107 S.Ct. at p. 3126]; cf. Wiggins v. Corcoran, supra, 288 F.3d at pp. 641-642), but foreclosed the introduction of substantial aggravating evidence in rebuttal or on cross-examination that could have undermined the defense by depicting petitioner as aggressive and desensitized to violence. (See People v. Gonzalez (1990) 51 Cal.3d 1179, 1253 [275 Cal.Rptr. 729, 800 P.2d 1159]; People v. Miranda (1987) 44 Cal.3d 57, 122 [241 Cal.Rptr. 594, 744 P.2d 1127], disapproved on another point in People v. Marshall (1990) 50 Cal.3d 907, 933, fn. 4 [269 Cal.Rptr. 269, 790 P.2d 676]; see also Burger v. Kemp, supra, 483 U.S. at pp. 794-795 [107 S.Ct. at pp. 3125-3126]; Darden v. Wainwright (1986) 477 U.S. 168, 186 [106 S.Ct. 2464, 2474, 91 L.Ed.2d 144]; Strickland, supra, 466 U.S. at p. 700 [104 S.Ct. at p. 2071].)
This evidence included shooting at the fleeing taxi driver robbery victim without provocation after just committing the robbery murder with Freddie Square, holding a gun to a young woman’s head, threatening to shoot a police officer, and stabbing other inmates. The prosecutor also could have argued this pattern of criminality—substantially accomplished prior to petitioner’s incarceration in prison—demonstrated his violence was a matter of predisposition rather than circumstance and would pose a danger to others if he were sentenced to life imprisonment. (Cf. People v. Millwee (1998) 18 Cal.4th 96, 151-152 [74 Cal.Rptr.2d 418, 954 P.2d 990].) Additionally, evidence of prison conditions could have led to the jury’s learning of petitioner’s second escape from custody. Although counsel stressed that the California facility in which petitioner would serve his life sentence was more secure than the Alabama institutions of the 1960’s and 1970’s, multiple inflammatory references to “escape” could have created a danger defense counsel reasonably sought to avoid.
In light of the foregoing, we conclude “counsel’s decision not to mount an all-out investigation into petitioner’s background in search of *1257mitigating circumstances was supported by reasonable professional judgment. It appears that [they did pursue the potential mitigation that] had been called to [their] attention and that there was a reasonable basis for [their] strategic decision that an explanation of petitioner’s history would not have minimized the risk of the death penalty. Having made this judgment, [they] reasonably determined that [they] need not undertake further investigation to locate witnesses who would [have made] statements about [petitioner’s] past.” (Burger v. Kemp, supra, 483 U.S. at pp. 794-795 [107 S.Ct. at p. 3126]; see also Bell v. Cone, supra, 535 U.S. at pp. 699-700 [122 S.Ct. at p. 1853].)  As one federal appellate court has explained, “a tactical decision not to pursue and present potential mitigating evidence on the grounds that it is double-edged in nature is objectively reasonable, and therefore does not amount to deficient performance.” (Rector v. Johnson (5th Cir. 1997) 120 F.3d 551, 564.)
Furthermore, the evidence petitioner now argues should have been presented was not conclusively and unambiguously mitigating.9 “ ‘ “[Mitigation . . . ,” after all, “[m]ay be in the eye of the beholder.” [Citation.]’ [Citation.]” (Burger v. Kemp, supra, 483 U.S. at p. 794 [107 S.Ct. at p. 3126].) Thus, although petitioner’s mother went to Detroit to improve her circumstances when he was two years old, she did not abandon him, but left him with an extended family including his “loving and responsible” grandfather, regularly sent money and clothing to her children, and returned several years later to remain in the family home. Despite the death of his grandfather when petitioner was 10, the testimony describing his upbringing and early family life generally showed it to be relatively stable and without serious privation or abuse. All but one of his siblings completed high school, and only one had a minor brush with the law. (See People v. Gonzalez, supra, 51 Cal.3d at p. 1253.) His mother and other relatives also counseled against associating with bad influences such as Freddie Square. Thus, petitioner did not suffer a home environment that would place his crimes in any understandable context or explain his resorting to crime every time he was released or escaped from prison.
The prosecutor could have exploited the testimony of the mental health experts to petitioner’s disadvantage as well. As the reference hearing testimony demonstrated, the evidence of mental difficulties was subject to dispute and would likely have reduced to a proverbial “battle of the experts.” Although the referee found one of petitioner’s experts, Dr. John Irwin, “one of the most compelling witnesses presented by the defense and his presentation and demeanor . . . impressive,” his testimony was limited to the *1258impact of the prison system and the ability of inmates to succeed outside the system. In part, he explained that convicts tend to react with rage to perceived insults, behavior they find difficult to shed even when discharged. Many of the inmate witnesses at the reference hearing confirmed this experience. While this might explain why petitioner reacted violently when Wheeler called him a “faggot” and a “punk,” it does not necessarily create a sympathetic impression. The jury could just as readily infer petitioner was unable to control lethal impulses on the slightest provocation. In addition, the prosecution’s expert, Dr. McNiel, challenged the diagnosis of petitioner as suffering from various mental disorders and concluded he simply “showed longstanding antisocial personality traits.” He rejected the description of petitioner as “dull normal” and testified his 93 IQ was “low average.” Dr. Jones agreed petitioner did not exhibit any evidence of brain damage, citing the fact he had successfully obtained and worked at a job, maintained a residence, and established a relationship. As the reference hearing demonstrated, a mental health penalty defense would also have given the prosecution several opportunities to repeat the circumstances of the crime as well as petitioner’s past criminality in questioning the experts on both direct and cross-examination as to whether petitioner exhibited an antisocial personality rather than some form of mental impairment. (See Darden v. Wainwright, supra, All U.S. at p. 186 [106 S.Ct. at p. 2474].)
With respect to prison conditions, while the evidence leaves no doubt petitioner endured horrifically demeaning and degrading circumstances, this evidence could equally have proved a double-edged sword, as the referee found. Presenting testimony about petitioner’s abusive prison experiences would have required counsel to call a series of witnesses, including one death row inmate, with serious felony records for murder, rape, and armed robbery, potentially drawing an unfavorable comparison with petitioner. At the very least, their criminal histories would automatically subject them to impeachment. (Evid. Code, § 788.) Many had themselves engaged in brutality while in prison and escaped with some frequency—again, in negative respects similar to petitioner. Rather than engendering sympathy, the evidence could well have reinforced an impression of him as a person who had become desensitized and inured to violence and disrespect for the law. (Cf. Darden v. Wainwright, supra, All U.S. at p. 186 [106 S.Ct. at p. 2474].) It also would raise the question of why petitioner so readily resorted to crime when he escaped the brutal and predatory conditions in Alabama and relocated to California, where he found work and started a family. In the same vein, petitioner’s abandonment of his own son to pursue a cocaine habit and his former criminal ways would belie the suggestion he merited sympathy due to his parents’ drinking and abandonment and his grandfather’s death.
*1259When “evaluat[ing] the conduct from counsel’s perspective at the time” (Strickland, supra, 466 U.S. at p. 689 [104 S.Ct. at p. 2065]), we must also consider the nature of the aggravating evidence, particularly the circumstances of the crime. Here, the facts of petitioner’s crimes evinced a callous disregard for human life. None of the three murders was an impulsive reaction to a situation unexpectedly out of control. (Cf. People v. Dillon (1983) 34 Cal.3d 441, 482-483 [194 Cal.Rptr. 390, 668 P.2d 697].) Rather, petitioner essentially lured the victims with a false sense of normalcy before brutally ending their lives. Nor was his motive simply robbery; he also raped and sodomized Brandon before killing her and murdered both Wheeler and Chism with considerable violence and evident sangfroid. Any penalty phase strategy must take into account the jury’s likely state of mind on having only recently heard an account of the defendant’s capital crimes and returned a guilty verdict. (Cf. People v. Cox (1991) 53 Cal.3d 618, 661 [280 Cal.Rptr. 692, 809 P.2d 351] [no ineffective assistance of counsel in failing to present guilt phase defense when counsel could anticipate guilty verdict and might need to preserve credibility of penalty phase theory that codefendant orchestrated killings].)
On these facts, we conclude counsel’s strategic decision to limit the scope of their investigation of mitigating background evidence and not to present such evidence at the penalty phase came within “the wide range of reasonable professional assistance.” (Strickland, supra, 466 U.S. at p. 689 [104 S.Ct. at p. 2065]; see People v. Miranda, supra, 44 Cal.3d at pp. 120-123.) Furthermore, as in People v. Miranda, supra, 44 Cal.3d at page 122, petitioner “fails ... to point to any evidence unknown to counsel which would have been discovered from such investigation and which would have influenced counsel’s decision.” All the purportedly mitigating evidence proffered on habeas corpus “would [have the] same . . . damaging result” counsel would have sought to avoid by adopting a different penalty phase strategy. (Ibid.) For example, testimony that petitioner’s prison experience may have prompted him to rape and sodomize Brandon in retaliation for Wheeler’s referring to him as a “faggot” might have given his acts an understandable context, but not a particularly sympathetic one because it could also confirm petitioner as an antisocial personality. (See, e.g., Burger v. Kemp, supra, 483 U.S. at p. 793 [107 S.Ct. at p. 3125]; Wiggins v. Corcoran, supra, 288 F.3d at p. 642.) A reasonable defense strategy would have kept this perception from the jury. For the same reasons, it is not “reasonably] proba[ble]” (Strickland, at p. 694 [104 S.Ct. at p. 2068]) petitioner was prejudiced by counsel’s rejection of a defense premised on evidence of petitioner’s upbringing, the Alabama prison conditions he experienced, and his mental health in light of the circumstances of the crimes, given the ambiguous nature of some mitigating evidence and the substantial potential for damaging rebuttal.
*1260This conclusion is consistent with our assessment of comparable facts in other decisions. For example, in People v. Gonzalez, supra, 51 Cal.3d at page 1251, counsel declined to present evidence of the defendant’s family life, which was loving, stable, and nonabusive and thus not particularly mitigating. In doing so, counsel kept the jury from hearing evidence suggesting the defendant’s possible involvement' in a rape and a shooting. (Id. at pp. 1248-1253.) We found that “[u]nder all the circumstances, . . . counsel’s decision to avoid damaging ‘rape’ evidence by omitting available character and background evidence was within the range of reasonable competence.” (Id. at p. 1253.)
In In re Jackson (1992) 3 Cal.4th 578 [11 Cal.Rptr.2d 531, 835 P.2d 371], disapproved on another point in In re Sassounian (1995) 9 Cal.4th 535, 545, footnote 6 [37 Cal.Rptr.2d 446, 887 P.2d 527], the defendant’s childhood was quite appalling and included physical abuse and frequent uprooting (In re Jackson, at pp. 606-609), unlike petitioner’s relatively stable home environment. Nevertheless, we deemed it reasonable that counsel, had he investigated, would nevertheless have withheld this evidence to prevent the jury from learning of the defendant’s assault on two women a year before the murders. (Id. at pp. 613-615.)
Perhaps the most apposite precedent is In re Ross (1995) 10 Cal.4th 184 [40 Cal.Rptr.2d 544, 892 P.2d 1287], in which the jury convicted the defendant of three murders as well as other associated crimes. As here, the defense called no penalty phase witnesses but presented certain evidence through stipulation, including the fact that an accomplice, who personally used a firearm during the crimes, did not receive a death sentence and that the defendant was 21 years old when he committed the murders. (Id. at p. 189.) We rejected the argument counsel was ineffective for failing to present mitigating evidence regarding Ross’s upbringing. The evidence was not only subject to impeachment—potentially leaving Ross worse off (id. at p. 206)—it would also have triggered damaging rebuttal, including evidence of sustained juvenile petitions for four counts of robbery and one count of brandishing a weapon, and other sustained petitions involving burglaries of guns. (Id. at pp. 206-207; cf. People v. Mayfield, supra, 5 Cal.4th at pp. 207-208 [finding no prejudice because additional defense witnesses could have “done severe damage to the penalty defense” on cross-examination].) In addition, we noted the circumstances of the murders, which were “not sudden explosions of angry violence or psychopathic serial killings” but calculated killings during a robbery and burglary. (In re Ross, at p. 213.) Moreover, “there was no compelling connection between [the mitigating evidence not introduced at the penalty phase] and the crimes . . . .” (Ibid.) On a substantially similar record, we reach the same conclusion that petitioner did not receive ineffective assistance of counsel.
*1261This determination also comports with the decision in Burger v. Kemp, supra, 483 U.S. 776, in which the United States Supreme Court found no deficiency in counsel’s performance at the penalty trial. In that case, counsel declined to present evidence of the defendant’s “ ‘neglectful, sometimes even violent, family background’ and testimony that his ‘mental and emotional development were at a level several years below his chronological age’ . . . .” (Id. at p. 789, fn. 7 [107 S.Ct. at p. 2123].) Such evidence would have risked “introducing facts [such as his difficulties with the law as a juvenile] not disclosed by [defendant’s] clean adult criminal record.” (Id. at p. 793 [107 S.Ct. at p. 3125].) For similar reasons, counsel declined to call the defendant as a witness. The defendant had never expressed remorse and apparently enjoyed talking about the crimes, which might have caused the jury to view his attitude as indifference or worse. (Id. at pp. 791-792 [107 S.Ct. at pp. 3124-3125].) Evidence of the defendant’s mental deficiencies could also have been deleterious because it would have demonstrated his “ ‘unpredictable propensity for violence which played a prominent role in the death of [the] victim.’ ” (Id. at p. 794 [107 S.Ct. at p. 3126].) On this record, the high court found the mitigating evidence “by no means uniformly helpful to [the defendant] because [it] suggested] violent tendencies that are at odds with the defense’s strategy of portraying [the defendant’s] actions on the night of the murder as the result of [his accomplice’s] strong influence upon his will.” (Id. at p. 793 [107 S.Ct. at p. 3125].)
The facts of this case offer even more compelling justification to forgo presenting background evidence in favor of a strategy to mitigate petitioner’s culpability by minimizing the jury’s exposure to his criminal history. The defendant in Burger endured a worse childhood and committed only one murder. He was still a teenager at the time of the crime; and his codefendant was primarily responsible for the plan to kidnap the victim, the sexual abuse inflicted, and the decision to kill. (Burger v. Kemp, supra, 483 U.S. at p. 779 [107 S.Ct. at pp. 3117-3118].) Rather than attribute his culpability to family or mental health problems, counsel sought instead to minimize it in light of the codefendant’s dominance. The United States Supreme Court found this decision reasonable under the circumstances. Whether or not counsel could have undertaken a more thorough investigation, “ ‘[w]e address not what is prudent or appropriate, but only what is constitutionally compelled.’ [Citation.]” (Id. at p. 794 [107 S.Ct. at p. 3126].) Applying similar reasoning, we reach the same conclusion on comparable facts. (See Campbell v. Kincheloe (9th Cir. 1987) 829 F.2d 1453, 1462-1463 [upholding counsel’s omission of evidence of the defendant’s abuse as a child, childhood medical problems, history of drug and alcohol abuse, attempted suicide, and father’s alcoholism, which foreclosed substantial aggravating evidence in rebuttal].)
Reaffirming this standard, the Supreme Court also declined to find ineffective assistance of counsel in Bell v. Cone, supra, 535 U.S. 685 [122 S.Ct. *12621843], where counsel presented no penalty phase evidence and waived closing argument. Viewing the record in its entirety and the totality of the circumstances from the perspective of counsel at the time of trial, the court found both decisions within the range of reasonable strategy. For example, with respect to the failure to call background witnesses, counsel “feared that testimony about [the defendant’s] normal youth might, in the jury’s eyes, cut the other way.” (Id. at pp. 699-700 [122 S.Ct. at p. 1853]; see Darden v. Wainwright, supra, All U.S. at pp. 185-186 [106 S.Ct. at pp. 2473-2474].) The court also noted that by waiving closing argument, counsel foreclosed the lead prosecutor, “who all agreed was very persuasive,” from additional argument “depicting] his client as a heartless killer just before the jurors began deliberation.” (Bell v. Cone, at pp. 701-702 [122 S.Ct. 1854].) In finding no deficiency in this representation, the court reiterated its cautionary admonition in Strickland “that a court must indulge a ‘strong presumption’ that counsel’s conduct falls within the wide range of reasonable professional assistance because it is all too easy to conclude that a particular act or omission of counsel was unreasonable in the harsh light of hindsight. [Citation.]” (Bell v. Cone, at pp. 701-702 [122 S.Ct. at p. 1854].)
Here, Miller viewed petitioner’s childhood surroundings as unimpressive because he found them comparable to his own. Counsel also had concern that having inmates describe the Alabama prison conditions would simply “trade ‘good acts’ for ‘bad acts’ ” and potentially open the door to additional evidence of petitioner’s criminal past. Under these circumstances, counsel could reasonably reject a background mitigation strategy in favor of an alternate basis to plead for petitioner’s life. (See Darden v. Wainwright, supra, All U.S. at p. 186 [106 S.Ct. at p. 2474]; cf. Williams v. Taylor (2000) 529 U.S. 362, 396 [120 S.Ct. 1495, 1514-1515, 146 L.Ed.2d 389].) Similar reasoning applies to Lenoir’s relatively brief closing argument—consistent in both tone and length with the limited penalty phase presentation of both the prosecution and the defense—which may have prompted the prosecutor to forgo his final statement, thereby leaving the defense with the last words to the jury. (Cf. Bell v. Cone, supra, 535 U.S. at pp. 701-705 [122 S.Ct. at pp. 1854-1855] [declining to find counsel’s decision to waive closing argument unreasonable under the circumstances].) Moreover, we have never equated length with effectiveness. (See People v. Mayfield, supra, 5 Cal.4th at p. 186.) In sum, strategic forbearance is not “inaction.” (Dis. opn., post, at p. 1274.)
We find petitioner’s reliance on In re Marquez (1992) 1 Cal.4th 584 [3 Cal.Rptr.2d 727, 822 P.2d 435] inapposite. (See In re Ross, supra, 10 Cal.4th at pp. 214-215.) The facts of Marquez—both at trial and on habeas corpus— stand in sharp contrast to this case. The mitigating evidence of the defendant’s childhood had no disadvantage or risk of impeachment or contradiction. Instead of showing he had endured experiences that may have *1263desensitized him to violence, the background evidence demonstrated his “generosity, his consideration of others, and his capacity for hard work.” (In re Marquez, at p. 602.) The circumstances of the crime were not as aggravated as here; nor were prior convictions or uncharged acts of criminal violence at issue. Counsel could therefore credibly argue that the defendant’s offenses were atypical rather than evidence of an antisocial personality. When offered the opportunity to argue mitigation, however, counsel simply stated “he had ‘nothing more’ to add.” (Id. at p. 607.)
Nor does In re Gay, supra, 19 Cal.4th 771, support petitioner’s argument. In that case, defense counsel—apart from his other shortcomings—persuaded the defendant to confess to a series of robberies, which not only became penalty phase factors in aggravation but also bolstered the prosecution’s theory the defendant killed the police officer victim to avoid arrest and imprisonment. (Id. at p. 827.) In addition, counsel “fraudulently and unethically maneuvered his own appointment to defend petitioner, [thereby causing petitioner to lose] any possibility of a fully developed penalty phase defense. [Citation.] He was saddled with an attorney who abandoned hope before any attempt to craft a penalty defense was undertaken.” (Id. at p. 828.) Counsel apparently had a capping relationship with both his assistant, who initially arranged his representation of the defendant, and with the mental health expert he retained, “who accepted only with the understanding that the case would not be complicated and would not place demands on his time.” (Ibid.) Counsel also “labored under a second and undisclosed potential conflict of interest—he was being investigated for misappropriation of client funds by the office of the same district attorney who was his adversary in the prosecution of petitioner.” (Ibid.) Cumulating these deficiencies with the failure to investigate and present any reasonable penalty phase defense and the absence of any trial strategy explaining the failure, the court concluded there was “a reasonable probability that absent counsel’s numerous failings and the conflicts of interest with which he was burdened, a different penalty verdict would have been reached.” (Id. at p. 830, fn. omitted.) The current facts are in no respect comparable.
Williams v. Taylor, supra, 529 U.S. 362, also does not assist petitioner. There, the United States Supreme Court found counsel provided ineffective representation during the sentencing trial by failing to investigate and present evidence of the defendant’s “nightmarish childhood,” model behavior while imprisoned, and borderline mental retardation. (Id. at pp. 395-396 [120 S.Ct. at pp. 1514-1515].) Although petitioner urges a similar result should follow here, the facts of Williams are plainly distinguishable.
To begin, counsel’s investigation in Williams was not limited either by inconclusive results or affirmative curtailment by the defendant; it was *1264essentially nonexistent due to an incorrect understanding of the law. (Williams v. Taylor, supra, 529 U.S. at pp. 395-396 [120 S.Ct. at pp. 1514-1515].) Reasonable investigation would have uncovered an extremely harsh family life, qualitatively worse than petitioner’s. (Id. at p. 395, in. 19 [120 S.Ct. at p. 1514].) Williams’s father beat him severely, and both parents were imprisoned for felony child abuse. (Id. at p. 395 [120 S.Ct. at p. 1514].)
Counsel had no tactical reason for withholding evidence regarding Williams’s life in prison. Unlike petitioner’s experiences, which might lead a jury to conclude his violence had become an established character trait, Williams received commendations “for helping to crack a prison drug ring and for returning a guard’s missing wallet.” (Williams v. Taylor, supra, 529 U.S. at p. 396 [120 S.Ct. at p. 1514].) Prison officials described Williams “as among the inmates ‘least likely to act in a violent, dangerous or provocative way.’ ” (Ibid.) The evidence of Williams’s mental disability, unlike petitioner’s, was substantially quantified; he was considered “borderline mentally retarded” and did not advance beyond sixth grade. (Ibid.)
Perhaps most important, the risk of damaging rebuttal was significantly less. Nor does it appear counsel proffered an alternate strategy for this reason. Although some potentially aggravating evidence about Williams’s background existed, it involved minor juvenile misconduct. Thus, the possible harm was minimal. (Williams v. Taylor, supra, 529 U.S. at p. 396 [120 S.Ct. at pp. 1514-1515].) Aiding and abetting larceny and pulling a false fire alarm pale in comparison to petitioner’s shooting at a fleeing robbery victim, placing a gun to a hostage’s head, threatening to kill a police officer, and prison stabbings. The jury may well retain sympathy despite learning of the former; it may well not in the case of the latter.
Not only was counsel’s representation in Williams obviously deficient, the prejudicial impact was greater. In contrast to petitioner’s brutal triple murder, “Williams turned himself in, alert[ed] police to a crime they otherwise would never have discovered, expressed] remorse for his actions, and cooperated] with the police after that.” (Williams v. Taylor, supra, 529 U.S. at p. 398 [120 S.Ct. at p. 1515].) In light of the substantial mitigating evidence and minimal disadvantage in presenting it, the high court found “ ‘a reasonable probability that the result of the sentencing proceeding would have been different’ if competent counsel had presented and explained the significance of all the available evidence.” (Id. at p. 399 [120 S.Ct. at p. 1616].) For the reasons previously discussed, we do not reach a similar conclusion on substantially dissimilar facts.
*1265We also find recent Ninth Circuit Court of Appeals decisions distinguishable even if we assume they are correct.
In Silva v. Woodford (9th Cir. 2002) 279 F.3d 825, the court found ineffective assistance at the penalty phase due to counsel’s failure to engage in any significant investigation of mitigating evidence regarding Silva’s family background, mental health history, drug usage, and incarceration record. Counsel apparently limited the investigation based on Silva’s request not to contact his relatives (id. at p. 839), but the court determined the decision was nevertheless not reasonable. (Cf. Strickland, supra, 466 U.S. at p. 691 [104 S.Ct. at pp. 2066-2067].) The court found Silva had requested only that counsel not call his parents as witnesses; he did not object to counsel’s contacting them for informational purposes or calling other relatives as witnesses. (Silva v. Woodford, at pp. 839-840.) At the same time, counsel’s “trial ‘strategy’ was based entirely on an overbroad acquiescence in his client’s demand that he refrain from calling his parents as witnesses.” (Id. at p. 846.) The evidence also did not show that the abandonment of the investigation was based on the defendant’s informed and knowing judgment. (Id. at pp. 840-841.) Finally, the Ninth Circuit Court of Appeals found counsel’s deficient investigation was likely prejudicial in part because the jury specifically asked the court about the actual effect of a sentence of life imprisonment without parole and appeared to be seriously considering that sentence. (Id. at pp. 849-850.)
By contrast in this case, counsel here did perform some background investigation, including an interview with petitioner’s mother despite his objection, after which they pursued a different penalty defense—one that would have been compromised by background mitigation evidence. The referee expressly found not only that petitioner “personally adamantly objected to his attorneys approaching his mother and family and having them testify” but also that his on-the-record statements reflected he understood the consequences of his decision. With respect to the question of prejudice, in addition to the reasons previously discussed, the record here contains no indication the jury was inclined to sentence petitioner to life imprisonment and might have been persuaded by additional or alternate mitigation evidence.
In Turner v. Calderon (9th Cir. 2002) 281 F.3d 851, counsel failed to present evidence of the defendant’s long-term drug use and its effects on various aspects of his behavior. (See id. at pp. 892-894.) Nevertheless, the district court denied the defendant an evidentiary hearing, which left the reviewing court with no record as to the nature and extent of any investigation or penalty strategy. (Id. at p. 895.) Because counsel may have been *1266incompetent in not presenting the drug use evidence in conjunction with information about the defendant’s abusive childhood, and the omission could have been prejudicial, the court found he was entitled to an evidentiary hearing. (Ibid.) Here, the record is clear counsel made a sufficient investigation to adopt an alternate strategy—one inconsistent with the theory now proposed by petitioner—and that further investigation would not reasonably have influenced that decision. (See, e.g., Wiggins v. Corcoran, supra, 288 F.3d at p. 642.) As this court concluded in People v. Miranda, supra, 44 Cal.3d at pages 122-123, “the information an investigation would have disclosed would only have confirmed counsel’s tactical decision not to open the ‘Pandora’s Box’ of [petitioner’s] violent background. This decision, as we have determined, was within the range of reasonably competent assistance. (Cf. Burger v. Kemp[, supra,] 483 U.S. [776]; Strickland v. Washington, supra, 466 U.S. at pp. 699-700 [80 L.Ed. 2d at p. 701].)” (Fn. omitted.)
V. Other Claims
Because our order to show cause, and our subsequent reference order, were confined to specific claims of ineffective assistance of counsel, we do not address herein either the merits of any other claims set forth in the petition, or any procedural bars that might apply to such claims. The petition for writ of habeas corpus itself will be resolved, as is our normal procedure, by a separate order.
VI. Conclusion
The petition for writ of habeas corpus is denied and the order to show cause is discharged.
Baxter, J., Werdegar, J., Chin, J., and Morrison, J.,* concurred.

In his exceptions to the referee’s report, petitioner points out that he was 10 years old, not 11, when his grandfather died. The Attorney General agrees.

In this regard, the referee observed, “The length of time available to develop, expand and refine the depth of the evidence presented at this reference hearing obviously creates an artificial setting and this court notes that the abundance and massiveness of the evidence presented could not and would not have been the same in an original trial. Strategic considerations alone would have undoubtedly resulted in a greater refinement of the quality of evidence presented, but this issue is outside the scope of the referee’s findings.”

There was testimony that petitioner’s grandfather had a drinking problem and that petitioner and his siblings were beaten, but the referee described the evidence on these points as “inconsistent.”

Petitioner was convicted of murder based on his participation in the robbery of the grocery clerk in November 1967. Six months later, he was convicted of armed robbery of the taxi driver. The jurors at petitioner’s penalty trial were told only of the conviction dates, not the date when the crimes were committed, which may have led them to believe the crimes were unrelated.

Petitioner had previously attempted but failed to escape from the same jail.

Although he failed to do so in the reference hearing, petitioner requests this court take judicial notice of certain materials (the Diagnostic and Statistical Manual of Mental Disorders (3d ed. 1980) and the Comprehensive Textbook of Psychiatry/III (3d ed. 1980)) as well as several published decisions, all of which he argues rebut the referee’s conclusions regarding the development and use of posttraumatic stress disorder as a defense in criminal proceedings. Even assuming it would be appropriate to take judicial notice of matters not presented for the referee’s consideration (cf. People v. Hardy (1992) 2 Cal.4th 86, 134 [5 Cal.Rptr.2d 796, 825 P.2d 781]), the psychiatric materials constitute neither “[fjacts and propositions that are of such common knowledge . . . that they cannot reasonably be the subject of dispute” (Evid. Code, § 452, subd. (g)) nor “[f]acts and propositions that are not reasonably subject to dispute and are capable of immediate and accurate determination by resort to sources of reasonably indisputable accuracy.” (Id., subd. (h); cf. Ake v. Oklahoma (1985) 470 U.S. 68, 81 [105 S.Ct. 1087, 1095, 84 L.Ed.2d 53] [“Psychiatry is not, however, an exact science, and psychiatrists disagree widely and frequently on what constitutes mental illness”].) Accordingly, they are not the proper subject of judicial notice. While we may judicially notice decisional law (see Evid. Code, § 452, subd. (a)), such notice does not extend to the facts of such cases when the point on which they are submitted is, as here, in dispute. Thus, we grant petitioner’s request in part, but do not accord any evidentiary weight to the submission.

Lenoir had died prior to the reference hearing.

Contrary to the implication of the dissent (see dis. opn., post, at p. 1274), the record contains no evidence counsel had any ulterior purpose in traveling through New Orleans to Mobile, which apparently had no direct airline connection from Los Angeles.

As explained, ante, at page 1251, even without rebuttal witnesses, the prosecutor could have elicited facts on cross-examination to deflate the mitigating impact of this evidence.
