least briefly every hour. Based on testimony provided by a vocational expert

(“VE”) that Coleman could perform three specified occupations, the ALJ then held

that Coleman could perform work that exists in significant numbers in the

economy. He therefore denied benefits.

Coleman filed suit in district court, contending that the ALJ erred in two

ways. First, Coleman faulted the ALJ for disbelieving her testimony of severe pain

on the grounds that her fibromyalgia did not result in certain physical symptoms

and that Coleman failed to lose weight as treatment for her obesity. Second,

Coleman argued that the ALJ violated Social Security Ruling (“SSR”) 00-4p by

failing to ask the VE whether the VE’s testimony conflicted with the Dictionary of

Occupational Titles (“DOT”). The district court held that any errors committed by

the ALJ were harmless.

1. The ALJ relied on the absence of objective physical symptoms of

severe pain as a basis for disbelieving Coleman’s testimony regarding her

symptoms. He erred insofar as Coleman’s pain is related to her fibromyalgia,

which is a “disease that eludes [objective] measurement.” Benecke v. Barnhart,

379 F.3d 587, 594 (9th Cir. 2004) (internal quotation marks omitted). He also

erred by holding, in the middle of a discussion of Coleman’s obesity, that her

“failure to lose weight reflects on her credibility.” See Orn v. Astrue, 495 F.3d
3

625, 638 (9th Cir. 2007) (“[T]he failure to follow treatment for obesity tells us

little or nothing about a claimant’s credibility.”). 

Although we find these errors troubling, we conclude that they were

harmless. “[T]here remains substantial evidence supporting the ALJ’s conclusions

on credibility,” Carmickle v. Comm’r, Soc. Sec. Admin., 533 F.3d 1155, 1162 (9th

Cir. 2008) (internal quotation marks and alteration omitted), including Coleman’s

failure to follow repeated medical recommendations that she treat her pain with

exercise and increased activity levels, see, e.g., Fair v. Bowen, 885 F.2d 597, 603-

04 (9th Cir. 1989). The ALJ’s errors therefore “do[] not negate the validity of [his]

ultimate credibility conclusion” or his resulting determination of Coleman’s

residual functional capacity. Carmickle, 533 F.3d at 1162 (internal quotation

marks and alteration omitted).

2. As the Commissioner concedes, the ALJ further erred by failing to ask

the VE if the VE’s testimony conflicted with the DOT. See Massachi v. Astrue,

486 F.3d 1149, 1152-53 (9th Cir. 2007). This error would be harmless if no

conflict existed or if the VE “provided sufficient support for [his] conclusion so as

to justify any potential conflicts.” Id. at 1154 n.19. 

As in Massachi, however, we are faced with “an apparent conflict” and an

insufficient “basis for the [VE’s] deviation.” Id. Under the DOT’s definitions,
 Similarly, the ALJ’s conclusion that Coleman can perform her prior 1

occupation of administrative clerk conflicts with the DOT’s classification of that

occupation as light. The ALJ “must definitively explain this” conflict, but failed to

do so. Pinto v. Massanari, 249 F.3d 840, 847 (9th Cir. 2001).

sedentary work “involves sitting most of the time,” and the relevant type of light

work “requires walking or standing to a significant degree.” Dictionary of

Occupational Titles App. C (4th ed. 1991). Many occupations involving these

requirements could not accommodate Coleman’s need to switch between sitting,

standing, and walking on an hourly basis. The VE nevertheless testified that

Coleman could perform certain sedentary and light occupations, creating an

apparent conflict with the DOT.1

 The VE’s explanations for this testimony were brief and, so far as the record

reveals, involved uninformed guesswork about the nature of the specified

occupations. Such speculative explanations are insufficient to reconcile the

conflict. See, e.g., Tommasetti v. Astrue, 533 F.3d 1035, 1042 (9th Cir. 2008)

(holding that “brief and indefinite testimony” is not “persuasive evidence”

explaining a conflict). Accordingly, we reverse the district court’s holding that the

ALJ’s violation of SSR 00-4p constituted harmless error. We remand to the

district court with instructions to remand to the Commissioner so that the ALJ may

hear further testimony from the VE and comply with SSR 00-4p.
