Reasoning about actual causation in reversible and irreversible causal structures.

Area of Science:

• Cognitive Psychology
• Philosophy of Science
• Causal Inference

Background:

• Traditional studies on actual causation often overlook causal reversibility.
• Ross and Woodward (2022) theorized that reversibility impacts causal judgments, particularly in late-preemption scenarios.
• Existing research typically finds earlier events are causes, and later events are not.

Purpose of the Study:

• To investigate the effect of causal reversibility on people's judgments of actual causation.
• To test the hypothesis that causal reversibility leads to later events being perceived as actual causes.
• To clarify discrepancies with previous findings by examining the role of 'maintaining' versus 'triggering' in causal judgments.

Main Methods:

• Three main experiments and one supplementary study involving 590 participants.
• Participants evaluated causal contributions in scenarios with varying degrees of reversibility.
• Analysis focused on whether participants identified later events as causes in reversible structures.

Main Results:

• Causal reversibility significantly influenced judgments of actual causation as predicted.
• Later events in reversible causal structures were perceived to have an actual causal contribution.
• Previous studies may have underestimated the role of later causes due to ambiguous questioning about 'triggering' vs. 'maintaining'.

Conclusions:

• Causal reversibility is a key factor in how people assign actual causation.
• The distinction between maintaining and triggering effects is crucial for understanding causal judgments.
• Future research in causal cognition should consider the concept of maintaining causality.
