Opinion:
ON REHEARING EN BANC
JORGENSON, Judge.
By this appeal we are asked to adopt the rule announced by the California Supreme Court in Tarasoff v. Regents of University of California and hold that a psychiatrist who allegedly "knows, or should know," that a patient of his presents a serious threat of violence to a third party has a duty to warn the intended victim. Because this case is of great public importance, the court, on its own motion, granted rehearing en banc. For the reasons which follow, we decline to recognize such a duty and affirm the order of the trial court dismissing plaintiffs' complaint with prejudice for failure to state a cause of action.
On May 13, 1986, Lawrence Blaylock shot and killed Wayne Boynton, Jr. Blay-lock had been an outpatient of psychiatrist Milton Burglass, M.D. Boynton's parents sued Dr. Burglass for malpractice. The complaint alleged that Dr. Burglass failed to hospitalize Blaylock, failed to warn Boynton, Boynton's family, or the police that Blaylock was violence-prone and had threatened serious harm to Boynton, and failed to prescribe the proper medications for Blaylock. Because Dr. Burglass refused to release his patient's medical records to the plaintiffs, the complaint did not contain allegations of specific threats made by Blaylock against the victim. Instead, plaintiffs alleged simply that the psychiatrist "knew, or in the exercise of reasonable due care, should have known that prior to May 13, 1986, Lawrence Blay-lock, Jr. had threatened serious harm to a specific victim, to wit: Wayne Boynton, Jr." The complaint further alleged that, as a direct and proximate consequence of the psychiatrist's negligence, Blaylock shot and killed Boynton.
Dr. Burglass moved to dismiss the complaint for failure to state a claim for relief. The trial court granted the motion with prejudice; we affirm.
This is a case of first impression in Florida. Although other jurisdictions have followed the lead of the California Supreme Court in the landmark decision of Tarasoff v. Regents of Univ. of California, 17 Cal.3d 425, 131 Cal.Rptr. 14, 551 P.2d 334 (1976), we reject that "enlightened" approach.
Florida courts have long been loathe to impose liability based on a defendant's failure to control the conduct of a third party. See, e.g., Bankston v. Brennan, 507 So.2d 1385 (Fla.1987) (social host not liable for serving alcoholic beverages to individual who then injures another); Paddock v. Chacko, 522 So.2d 410 (Fla. 5th DCA 1988) (psychiatrist had no duty to forcibly detain patient who later attempted to commit suicide); Vic Potamkin Chevrolet, Inc. v. Home, 505 So.2d 560 (Fla. 3d DCA 1987) (automobile dealer not liable for buyer's negligent driving once ownership of automobile transferred to buyer), approved, 533 So.2d 261 (Fla.1988). When the duty sought to be imposed is dependent upon standards of the psychiatric profession, we are asked to embark upon a journey that "will take us from the world of reality into the wonderland of clairvoyance." Tarasoff, 551 P.2d at 354, 131 Cal.Rptr. at 34 (Mosk, J., concurring and dissenting). Psychiatry "represents the penultimate grey area . particularly with regard to issues of foreseeability and predictability of future dangerousness." Lindabury v. Lindabury, 552 So.2d 1117, 1118 (Fla. 3d DCA 1989) (Jorgenson, J., dissenting) (citations omitted); Fischer v. Metcalf, 543 So.2d 785, 787 n. 1 (Fla. 3d DCA 1989) ("Unlike other branches of medicine in which diagnoses and treatments evolve from objective, empirical, methodological foundations, 'psychiatry is at best an inexact science, if, indeed, it is a science_'") (citations omitted). It is against the backdrop of this uncertain and inexact science that we address the legal issues presented by this appeal.
I. The Duty to Warn
Plaintiffs contend that Dr. Burglass had a duty, under the common law, to warn Boynton (or the police, or Boynton's family) that Blaylock intended to harm him. In our view, imposing on psychiatrists the duty that plaintiffs urge is neither reasonable nor workable and is potentially fatal to effective patient-therapist relationships.
Under the common law, a person had no duty to control the conduct of another or to warn those placed in danger by such conduct; however, an exception to that general rule can arise when there is a special relationship between the defendant and the person whose behavior needs to be controlled or the person who is a foreseeable victim of that conduct. See Fischer v. Metcalf, 543 So.2d 785, 787 n. 1 (Fla. 3d DCA 1989); Department of Health & Rehab. Servs. v. Whaley, 531 So.2d 723 (Fla. 4th DCA 1988); Garrison Retirement Home Corp. v. Hancock, 484 So.2d 1257 (Fla. 4th DCA 1985); see also Rest.2d Torts § 314-320. Implicit in the creation of that exception, however, is the recognition that the person on whom the duty is to be imposed has the ability or the right to control the third party's behavior. Restatement § 316-319. "Thus, in the absence of a relationship involving such control, the exception to the general rule, that there is no duty to control the conduct of a third party for the protection of others, should not be applicable." Hasenei v. United States, 541 F.Supp. 999, 1009 (D.Md.1982) (psychiatrist who had no right or ability to control voluntary outpatient's behavior could not be held liable for failure to warn patient's victim, especially where psychiatrist unable to predict identifiable danger posed by patient to any person). In Tarasoff, the California Supreme Court characterized the relationship between the psychiatrist and the patient or the intended victim of the patient by stating that "[t]here now seems to be sufficient authority to support the conclusion that by entering into a doctor-patient relationship the therapist becomes sufficiently involved to assume some responsibility for the safety, not only of the patient himself, but also of any third person whom the doctor knows to be threatened by the patient." Tarasoff, 131 Cal.Rptr. at 24, 551 P.2d at 344, citing Fleming & Maximov, The Patient or His Victim: The Therapist's Dilemma, 62 Cal. L.Rev. 1025, 1030 (1974). The Tarasoff court did not address the issue of the psychiatrist's control over the patient but simply opined that "[s]uch a relationship may support affirmative duties for the benefit of third persons." 131 Cal.Rptr. at 23, 551 P.2d at 343.
In this case, Blaylock was a voluntary psychiatric outpatient treated by Dr. Burglass. A federal court has described the relationship between a psychiatrist and a voluntary outpatient as lacking "sufficient elements of control necessary to bring such relationship within the rule of § 315." Hasenei, 541 F.Supp. at 1009. We agree. "Once the suggestion of control is eliminated, there is nothing in the nature of the relationship between a psychiatrist and his patient to support an exception to the tort law presumption." Stone, The Tarasoff Decisions: Suing Psychotherapists to Safeguard Society, 90 Harv.L.Rev. 358, 366 (1976). The complaint nowhere alleges that Dr. Burglass had either the right or the ability to control Blaylock's behavior. Dr. Burglass, therefore, cannot be charged with the duty to control. Compare Nova Univ., Inc. v. Wagner, 491 So.2d 1116 (Fla.1986) (where institution that housed and rehabilitated children with behavioral and emotional problems had taken charge of persons likely to harm others, institution had duty" to exercise reasonable care to avoid foreseeable attacks by its charges upon third persons).
The nature of the relationship between Dr. Burglass and the victim does not become any less tenuous or give rise to a more definable duty by attempting to transform the duty to control Blaylock's behavior into a duty to warn Boynton or others about Blaylock's behavior or to otherwise protect them. "The duty to warn is an expression of humanitarianism and the spirit of the Good Samaritan_" Currie v. United States, 836 F.2d 209, 213 (4th Cir.1987). The creation, by process of law, of such a duty would be no more than a recognition that "[o]ur current crowded and computerized society compels the interdependence of its members. In this risk-infested society we can hardly tolerate the further exposure to danger that would result from a concealed knowledge of the therapist that his patient was lethal." Tarasoff, 131 Cal.Rptr. at 27, 551 P.2d at 347. By imposing such duties, courts recognize the responsibilities inherent in social living and human relations. McIntosh v. Milano, 168 N.J.Super. 466, 403 A.2d 500, 507 (1979). However, imposition of such a duty must be reasonable, and must give the parties on whom the duty is imposed fair notice of what is required of them. We decline to fashion a rule of law from such social duties.
II. Predictions of Dangerousness
Because psychiatry is, at best, an inexact science, courts should be reluctant to impose liability upon psychiatrists. "Psychiatry is not, however, an exact science, and psychiatrists disagree widely and frequently on what constitutes mental illness, on the appropriate diagnosis to be attached to given behavior and symptoms, on cure and treatment, and on the likelihood of future dangerousness." Ake v. Oklahoma, 470 U.S. 68, 81, 105 S.Ct. 1087, 1095, 84 L.Ed.2d 53, 64-65 (1985). Although Florida courts recognize that a physician owes a duty to warn members of a patient's immediate family of the existence and dangers of a communicable disease, Hofmann v. Blackmon, 241 So.2d 752 (Fla. 4th DCA 1970), cert. denied, 245 So.2d 257 (Fla.1971), "[u]nlike a physician's diagnosis, which can be verified by x-ray, surgery, etc., the psychiatrist cannot verify his diagnosis, treatment or predicted prognosis except by long-term follow-up and reporting." Nesbitt v. Community Health of South Dade, Inc., 467 So.2d 711, 717 (Fla. 3d DCA 1985) (Jorgenson, J., concurring and dissenting), quoting Almy, Psychiatric Testimony: Controlling the "Ultimate Wizardry" in Personal Injury Actions, 19 The Forum 233, 243 (1984).
The outward manifestations of infectious diseases lend themselves to accurate and reliable diagnoses. However, the internal workings of the human mind remain largely mysterious. The "near-impossibility of accurately or reliably predicting dangerousness has been well-documented." Hasenei v. United States, 541 F.Supp at 1011, citing Diamond, The Psychiatric Prediction of Dangerousness, 123 U.Pa.L.Rev. 439 (1974); Ennis & Litwack, Psychiatry & The Presumption of Expertise: Flipping Coins in the Courtroom, 62 Calif.L.Rev. 693 (1974); Stone, supra.
To impose a duty to warn or protect third parties would require the psychiatrist to foresee a harm which may or may not be foreseeable, depending on the clarity of his crystal ball. Because of the inherent difficulties psychiatrists face in predicting a patient's dangerousness, psychiatrists cannot be charged with accurately making those predictions and with sharing those predictions with others. Therefore, we decline to charge Dr. Burglass with such a duty.
III. Confidentiality and the Psychiatrist-Patient Relationship
Imposing on psychiatrists a duty to warn third parties would not only be unreasonable and unworkable, it would also wreak havoc with the psychiatrist-patient relationship.
Confidentiality is the cornerstone of the psychiatrist-patient relationship. The psychotherapist-patient privilege is codified in the Florida Evidence Code, section 90.503, Florida Statutes (1985), which provides that "[a] communication between psychotherapist and patient is 'confidential' if it is not intended to be disclosed to third per-sons_" Had Dr. Burglass disclosed Blaylock's real or apparent threat to Boyn-ton, he would have breached not only his ethical duty to his patient, but also section 90.503.
In addition to holding that there is no common-law duty to warn, we further hold that the Florida legislature has not created such a duty. Plaintiffs argue that section 455.2415, Florida Statutes (1989), applies in this case and allows Dr. Burglass to divulge his patient's communications "to the extent necessary to warn a potential victim." Section 455.2415 provides, in pertinent part, that if:
(1) A patient is engaged in a treatment relationship with a psychiatrist;
(2) Such patient has made an actual threat to physically harm an identifiable victim or victims; and
(3) The treating psychiatrist makes a clinical judgment that the patient has the apparent capability to commit such an act and that it is more likely than not that in the near future the patient will carry out the threat, the psychiatrist may disclose patient communications to the extent necessary to warn any potential victim or to communicate the threat to a law enforcement agency.
However, section 455.2415 became effective on February 8, 1988; the legislature specifically provided that "[t]his act does not apply to causes of action arising prior to the effective date of this act." Chapter 88-1, § 10, Laws of Florida. Wayne Boyn-ton was murdered on May 13, 1986, long before section 455.2415 was in force. Moreover, section 455.2415 does not require a psychiatrist to warn in these circumstances but is couched in permissive terms, and merely provides that a psychiatrist "may disclose patient communications ." We conclude, therefore, that section 455.2415 has no effect on this case.
Imposing on Dr. Burglass a duty to warn would not only run afoul of the psychiatrist-patient confidentiality privilege, but would also severely hamper, if not destroy, the relationship of trust and confidence that is crucial to the treatment of mental illness.
By the very nature of psychotherapy, the patient is encouraged to freely vocalize his fantasies, repressed feelings, and desires. Requiring psychiatrists to warn potential victims every time a patient expresses feelings of anger toward someone would seriously interfere with the treatment, both because of the breach in confidentiality and the practical problem of determining whether a patient really intended to carry out his violent feelings.
Wolfe, The Scope of a Psychiatrists's Duty to Third Persons: The Protective Privilege Ends Where the Public Peril Begins, 59 Notre Dame L.Rev. 770, 785-86 (1984). Requiring a psychiatrist to breach that privilege in order to warn a third party would inhibit the free expression vital to diagnosis and treatment and would, thus, undermine the very goals of psychiatric treatment.
IY. Conclusion
The criminal act committed by Lawrence Blaylock resulted in the tragic and irreparable loss of Wayne Boynton's life. In the face of such a loss, we understand the need of the victim's family to blame an identifiable source and to ask this court to recognize that the psychiatrist who treated their son's killer had a legal obligation to warn them, their son, or the police of his patient's murderous intent. There is not sufficient science to allow the accurate prediction of future dangerousness. Because such predictions are fraught with uncertainty, we find that it would be fundamentally unfair to charge a psychiatrist with the duty to warn.
Based on the foregoing analysis, we affirm the dismissal, with prejudice, of plaintiff's complaint for failure to state a cause of action.
Affirmed.

. Tarasoff v. Regents of University of California, 17 Cal.3d 425, 131 Cal.Rptr. 14, 551 P.2d 334 (1976).
. The court thanks the Florida Department of Health & Rehabilitative Services, the Academy of Florida Trial Lawyers, and the Florida Defense Lawyers Association — the Amici Curiae that appeared in this case — for their valuable assistance.
. The criminal case stemming from this incident is Blaylock v. State, 537 So.2d 1103 (Fla. 3d DCA 1988), rev. denied, 547 So.2d 1209 (Fla.1989).
. In this court, plaintiffs assert only that Dr. Burglass had a duty to warn Boynton, his family, or the police that Blaylock posed a serious threat to Boynton's safety.
. For the purpose of deciding this appeal, we take as true all facts pled in the complaint, and thus assume that Blaylock made an actual, specific threat against Wayne Boynton. See Connolly v. Sebeco, 89 So.2d 482 (Fla.1956).
. For an overview of decisions from other jurisdictions that have addressed Tarasoff, see generally Annotation, Liability of One Treating Mentally Afflicted Patient for Failure to Warn or Protect Third Persons Threatened by Patient, 83 A.L.R.3d 1201 (1978 & Supp.1990).
. In Tarasoff, the California Supreme Court held that "[w]hen a therapist determines, or pursuant to the standards of his profession should determine, that his patient presents a serious danger of violence to another, he incurs an obligation to use reasonable care to protect the intended victim against such danger." 131 Cal.Rptr. at 20, 551 P.2d at 340. Four years later, the California Supreme Court narrowed the scope of its holding in Tarasoff, and held that a county's duty to warn of the imminent release from confinement of a dangerous and violent individual "depends upon and arises from the existence of a prior threat to a specific identifiable victim." Thompson v. County of Alameda, 27 Cal.3d 741, 167 Cal.Rptr. 70, 80, 614 P.2d 728, 738 (1980).
. Although we use the term "psychiatrist" throughout this opinion, our decision today applies equally to psychologists, psychotherapists, and other mental health practitioners.
. Plaintiffs failure to allege that Dr. Burglass had the ability to control Blaylock's behavior also goes to the issue of proximate cause. If Dr. Burglass lacked the ability to control Blaylock's behavior, his failure to control cannot be said to be the proximate cause of the criminal act. See Hasenei, 541 F.Supp. at 1012, n. 22.
. For a useful discussion of social science methodology and its appropriate reception in the courts, see generally J. Monahan & L. Walker, Social Science in Law: Cases & Materials (2d Ed.1990).
. We also affirm the denial of plaintiffs' motion to strike defendant's motion to dismiss.
. We certify to the Supreme Court of Florida that the question resolved in this case is one of great public importance.
