Interrogation tactics may have downstream consequences on innocent and guilty defendants' plea decisions

Area of Science:

• Psychology
• Criminology
• Legal Studies

Background:

• Interrogation tactics, including minimization and maximization, are commonly used in legal settings.
• The downstream effects of these tactics on defendants' subsequent plea decisions are not fully understood.

Purpose of the Study:

• To investigate the impact of minimization and maximization interrogation tactics on plea decisions of both innocent and guilty defendants.
• To examine the mediating roles of perceived trial prospects and anxiety in these decisions.

Main Methods:

• A plea decision-making task involving 262 participants who were either innocent or guilty of cheating.
• Participants were subjected to control, minimization, or maximization interrogation tactics.
• Plea decisions, perceived conviction likelihood, estimated punishment, and state anxiety were recorded.

Main Results:

• Guilty participants were significantly more likely to plead guilty than innocent participants.
• Minimization tactics reduced guilty pleas in innocent participants but not in guilty ones.
• Maximization tactics reduced guilty pleas in innocent participants but increased them in guilty participants.

Conclusions:

• Interrogation tactics can significantly influence plea decisions beyond the interrogation room.
• The findings raise concerns about the ethical implications and effectiveness of using minimization and maximization tactics in real-world interrogations.
• Further research is needed to understand the long-term consequences and potential reforms for interrogation practices.
