How people explain actions performed by groups and individuals

Area of Science:

• Social Psychology
• Cognitive Science
• Group Dynamics

Background:

• Understanding how individuals explain intentional actions is crucial for social cognition.
• Existing frameworks distinguish between agent's reasons and causal histories of reasons (CHRs).
• Research has yet to fully explore potential differences in explaining group versus individual actions.

Purpose of the Study:

• To investigate whether people explain intentional group actions differently from intentional individual actions.
• To test the hypothesis that causal histories of reasons (CHRs) are more frequently invoked when explaining group actions.
• To identify necessary conditions for this explanatory asymmetry.

Main Methods:

• A theoretical framework distinguishing agent's reasons from causal histories of reasons (CHRs) was proposed.
• Empirical studies were conducted to compare explanations for group and individual actions.
• Experimental manipulations examined the role of group perception (aggregate vs. joint action) and information availability.

Main Results:

• A significant asymmetry was found, with more CHR explanations used for group actions compared to individual actions.
• The asymmetry was contingent on the group being perceived as an aggregate of individuals, not a unified acting entity.
• Availability of general information about the group was also a necessary condition for the observed difference.

Conclusions:

• People's explanations for intentional actions differ based on whether the actor is an individual or a group.
• The perception of a group as an aggregate influences the reliance on causal histories of reasons.
• Findings shed light on how people conceptualize groups as entities and agents in social explanations.
