Definition
A false confession is an admission of guilt — sometimes detailed, sometimes accompanied by 'inside knowledge' that turns out to be supplied by interrogators — made by a person who did not commit the offence. Forensic researchers distinguish three types: voluntary (offered without external pressure, often by mentally ill confessors); coerced-compliant (the suspect admits guilt to escape pressure while privately maintaining innocence); and coerced-internalised (the suspect comes to believe they committed the offence).
DNA exoneration cases reveal that false confessions feature in roughly a quarter of US wrongful-conviction cases later overturned. They are produced disproportionately in long, accusatorial interrogations using minimisation, false-evidence ploys, and isolation — particularly against juveniles, intellectually disabled suspects, and the mentally ill.
Why it matters
Where it shows up
False-confession research underpins UK rules requiring recorded interviews, the right to legal advice in police custody, appropriate-adult schemes for vulnerable suspects, and judicial scrutiny of confession evidence at trial. In the US it has driven mandatory-recording laws in many states and expert-witness testimony challenging confession reliability.
