If not me, then who? Responsibility and replacement

Area of Science:

• Cognitive Psychology
• Social Psychology
• Decision Making

Background:

• Responsibility judgments depend on actual events and potential alternative outcomes.
• The concept of 'replaceability' influences how individuals assess blame and accountability.

Purpose of the Study:

• To investigate the impact of an individual's replaceability on judgments of responsibility.
• To develop and validate a quantitative model predicting responsibility based on counterfactual replaceability.

Main Methods:

• Developed the counterfactual replacement model to simulate alternative scenarios and assess outcome changes.
• Designed experimental paradigms to systematically manipulate replaceability (number of replacements, availability probability).
• Tested the model's predictions across three experiments in social and physical contexts.

Main Results:

• A person's responsibility is positively correlated with the difficulty of replacing them.
• The counterfactual replacement model accurately predicts human responsibility judgments.
• The model outperforms alternative approaches focusing solely on actual events.

Conclusions:

• Replaceability is a key factor in determining responsibility.
• The counterfactual replacement model provides a robust framework for understanding responsibility attribution.
• This research offers insights into social cognition and decision-making processes.
