Human adults prefer to cooperate even when it is costly

Area of Science:

• Cognitive Science
• Social Psychology
• Behavioral Economics

Background:

• Joint actions involve coordinated efforts for shared or individual objectives.
• Motivation for joint action is evident when individual efforts are insufficient.
• The drive for cooperation, even with added costs, remains less understood.

Purpose of the Study:

• To investigate human preference for joint action over individual action.
• To determine if this preference persists when individual action is more efficient.
• To explore the underlying motivations for choosing cooperation despite increased costs.

Main Methods:

• Utilized a utility-based empirical approach across five experiments.
• Compared the outcomes of joint actions versus individual actions.
• Assessed participants' choices when the costs of joint action exceeded its benefits.

Main Results:

• Human adults consistently demonstrated a preference for joint action.
• This preference held even when individual action was instrumentally superior.
• Results indicate a stable tendency towards cooperative behavior.

Conclusions:

• Humans possess an intrinsic preference for engaging in joint actions.
• This preference may stem from an inherent reward associated with cooperation.
• Cooperation is valued beyond mere instrumental necessity or efficiency.
