Evolving judgments of terror risks: foresight, hindsight, and emotion

Area of Science:

• Psychology
• Risk Perception
• Cognitive Bias

Background:

• Terrorism risk perception is influenced by personal experiences and emotions.
• Understanding cognitive and emotional responses to terror risks is crucial for public awareness.

Purpose of the Study:

• To examine the evolution of cognitive and emotional responses to terror risks in a national sample.
• To investigate the role of personal experience, hindsight bias, and emotion priming on risk judgments.

Main Methods:

• Longitudinal study of a nationally representative American sample (late 2001-late 2002).
• Assessed risk judgments, personal experiences, and employed a debiasing procedure.
• Utilized emotion-induction manipulations (fear and anger) to test effects on risk perception.

Main Results:

• Risk judgments aligned with personal experiences but were subject to hindsight bias.
• An intensive debiasing procedure did not correct hindsight bias.
• Fear priming increased risk estimates, while anger priming decreased them, affecting past and future risk perceptions.

Conclusions:

• Personal experiences and emotions significantly shape risk perception, often unconsciously.
• Hindsight bias affects memory of risk judgments, and debiasing is challenging.
• Emotion priming influences perceptions of both future and past risks, highlighting the impact of affective states on judgment.
