False confession and interrogation expert
Expert class library · Civil rights · Plaintiff side
A social psychologist or psychiatrist who explains to a jury how police interrogation techniques, and traits such as youth, intellectual disability or mental illness, can lead people to confess to crimes they did not commit. Courts are deeply divided. Some exclude the testimony as unreliable, as unhelpful because it does not fit the facts of the case, or as an improper comment on credibility, while the Ninth Circuit held in a civil rights suit that excluding such an expert was an abuse of discretion. The expert generally may describe the research and risk factors but may not say that a particular confession was false.

What this expert is retained to answer
- Does the testimony fit the facts: were the techniques and risk factors the expert describes actually present in this interrogation?
- Is the expert explaining general research, or offering an opinion that this confession was false or the defendant is credible?
- How reliable is the underlying research, and can it identify false confessions or only describe risk factors?
- Did the party proffering the expert make a sufficient threshold showing of the science before trial?
- In a civil rights suit, how does the testimony bear on whether the officers' conduct was coercive?
Methods
- Review of interrogation recordings, transcripts and police reports
- Identification of interrogation techniques such as isolation, confrontation and minimization
- Assessment of individual risk factors such as age, intellectual disability and mental illness
- Review of social science research on false confessions and wrongful convictions
- Comparison of the confession's details with known and publicly available facts
How the testimony is attacked
- No reliable method to identify a false confession. Courts question research that cannot say whether a given confession is false. In State v. Huante the South Dakota Supreme Court reversed an order admitting a false confession expert, holding his opinions were neither relevant nor reliable because the research overstated how often false confessions occur and lacked any means of detecting them.
- Lack of fit. Testimony about general risk factors must connect to the interrogation at issue. In State v. Dobbs the Wisconsin Supreme Court upheld excluding an expert's general testimony on interrogation techniques for lack of fit with the facts of the case.
- Comment on credibility and thin proffers. Many states bar any witness from saying another is lying. In State v. Coletta the Rhode Island Supreme Court upheld excluding a false confession expert where the defense proffered only a curriculum vitae and a one-line description of the testimony.
- Exclusion as an abuse of discretion. Courts that exclude these experts risk reversal where interrogation techniques are central to the claim. In Tekoh v. County of Los Angeles the Ninth Circuit held excluding a plaintiff's coerced confession expert in a section 1983 case misapplied Rule 702, and denied rehearing en banc over a ten-judge dissent.
- Jurors understand confessions. Opponents argue jurors can judge for themselves whether a confession was coerced, so expert testimony does not help.
What the public record shows
Courts have filed at least 39 opinions since 2015 that address this class of testimony under Daubert or Rule 702, as of October 4, 2026. 4 rulings that show how courts handle this class of testimony:
| Outcome | Case | Court | Year | Why |
|---|---|---|---|---|
| Excluded | State v. Huante2026 S.D. 6 | S.D. | 2026 | On the State's intermediate appeal in a murder case, the South Dakota Supreme Court reversed an order allowing a psychiatrist's testimony on false confessions, holding the opinions were not relevant or reliable because the research overstated the frequency of false confessions and offered no means of detecting them; one justice dissented. |
| Exclusion reversed | Tekoh v. County of Los Angeles91 F.4th 997 | 9th Cir. | 2024 | In a section 1983 suit claiming a coerced confession, the Ninth Circuit denied rehearing en banc of its panel decision that the district court misapplied Rule 702 and abused its discretion by excluding the plaintiff's expert on coerced confessions, which required a new trial; ten judges dissented from the denial. |
| Excluded | State v. Dobbs2020 WI 64 | Wis. | 2020 | The Wisconsin Supreme Court held the circuit court properly exercised its discretion in excluding an expert's general testimony on interrogation techniques and false confessions because it did not sufficiently fit the facts of the defendant's case, and affirmed the conviction. |
| Excluded | State v. ColettaNo. 2022-35-C.A. | R.I. | 2025 | Affirming child molestation convictions, the Rhode Island Supreme Court held the trial justice did not abuse her discretion in precluding the defense's false confession expert without a hearing, because the defense offered only his curriculum vitae and a statement that he would testify about psychological reactions to interrogation, and noted that no witness may testify that another is lying. |

Under amended Rule 702
Since December 1, 2023, Rule 702 says expressly that the party offering an expert must show the court it is more likely than not that the testimony meets each requirement: that it rests on sufficient facts or data, uses reliable methods, and reflects a reliable application of those methods to the case. Questions about the basis of an opinion are no longer automatically matters of weight for the jury. For how the circuits have applied the amendment, see the Rule 702 tracker, which follows each court of appeals; for what that means for preparing or attacking this class of expert, see the guide on amended Rule 702.
