severe exhaustion can lead to this type of false confession

"Although hard to fathom, false confessions happen surprisingly often; they are thought to play a role in up to a quarter of wrongful convictions in the US, according to the campaign group the Innocence Project." "Now a study has shed more light on how easily severe exhaustion can lead to this type of false confession." "It might seem obvious that people who are dead tired can make stupid decisions – but there is a long history of police and army interrogators using sleep deprivation as an interview technique."
