The PEACE method, which "encourages more of a dialogue between investigator and suspect"[3] was developed in Britain in response to the realisation that psychologically coercive techniques often led to false confessions.
It involves showing concern for the subject's welfare by asking how they want to be addressed, how much time they've got available to be interviewed and giving reassurance if the person seems anxious or nervous.
[5] This stage involves summarizing the subject's account of what happened and is designed to ensure there is mutual understanding between interviewer and interviewee about what has taken place.
This suggests that "some suspects enter the interview room having decided to confess and will carry out this decision irrespective of the investigator’s performance".
[6] In addition to investigations into benefit fraud, several studies have noted that training the police in the PEACE model has also produced beneficial results.
