How downplaying or exaggerating crime severity in a confession affects perceived guilt

Area of Science:

• Psychology
• Forensic Psychology
• Legal Psychology

Background:

• Factual inaccuracies in criminal confessions are common.
• The impact of confession errors on legal judgments requires further investigation.

Purpose of the Study:

• To examine how factual errors in confessions, specifically those amplifying or downplaying crime severity, influence judgments of guilt.
• To understand the psychological mechanisms underlying these influences.

Main Methods:

• Participants evaluated guilt based on confession statements and police reports with varying degrees of factual consistency.
• Experimental design manipulated confession accuracy (consistent, amplified severity, downplayed severity).
• Mediation analyses were employed to explore the pathways of influence.

Main Results:

• Both amplifying and downplaying errors in confessions reduced guilt judgments compared to consistent confessions.
• Errors downplaying crime severity increased guilt judgments through a direct effect, not mediated effects.
• Errors amplifying crime severity did not increase guilt judgments.

Conclusions:

• Factual errors in confessions complicate guilt attribution.
• Confessions that appear to minimize offense severity may inadvertently increase perceived guilt.
• Legal professionals should be aware of how confession discrepancies affect juror perceptions.
