Gudjonsson & MacKeith Flashcards
Intro
Police worried about false negative - guilty walk free
Public about false positive - identifying an innocent person as being guilty.
Why do innocent people make false confessions?
Higher suggestibility eg. Gudjonsson Suggestibility Scales GSS
Power of confessions
- Fundamental attribution error, this leads people to believe confessions to be powerful. (Our tendency to explain other peoples behaviour by internal states, and underestimate the influence of external factors).
- Ignore other evidence which may prove innocence if a confession has been made.
- Reluctant to look for external factors such as why a confession has been made. eg. manipulative interrogation techniques.
Why confess?
Psychoanalytic… superego/guilt complexes.
Decision making processes - suspects make a lot of choice throughout interview… some based on false information.
Social psychology - obedience and conformity.
Dispositional factors of false confessions
IQ
Age
Situational factors
Social isolation
Obedience to authority
Desire to escape
Question investigators ability to draw confessions from guilty subjects… or elicit confessions from innocent people.
Police are over confident in their ability to detect lying
Many people wavier rights to silence and legal representation
Interrogators use psychological strategies to help elect confessions.
Types of false confession

Coerced - Internalised
Coerced - Compliant
Voluntary
No obvious external pressure.
eg. protection someone else
need for fame
confessing to less crime to receive less punishment

- suspect is vulnerable eg.stress, fatigue
- presentation of false evidence eg. rigged forensic tests
Innocent suspects memory of their own actions may be altered
post event info used to alter
false memories implanted
Coerced - Compliant
Suspect confesses to escape from the stressful situation.
eg. due to extreme stress of interrogation, to escape pressure.
Give in to make it all go away or are offered incentives eg. allowed to sleep, eat, make phone call.
