Payoff information hampers the evolution of cooperation

Area of Science:

• Behavioral Economics
• Evolutionary Game Theory
• Social Psychology

Background:

• Cooperation models often assume payoff knowledge aids cooperation.
• Rationality and heuristics-based models are common explanations for human cooperation.

Purpose of the Study:

• To investigate the impact of payoff information on human cooperation in competitive environments.
• To challenge existing models where payoff knowledge is considered beneficial for cooperation.

Main Methods:

• Experimental setup with human subjects in a competitive interaction.
• Analysis of behavioral changes based on access to payoff information over time.
• Observation of learning heuristics and strategy adaptation.

Main Results:

• Long-term access to own payoff information decreases cooperative behavior.
• Short-term naive learning heuristics are replaced by adapted ones over time.
• Increased payoff information reduces the likelihood of adopting pro-cooperative heuristics.

Conclusions:

• Payoff information can be detrimental to the emergence of cooperation.
• Existing models may need revision to account for the negative impact of payoff knowledge.
• Development of two-tier models is suggested for a more accurate understanding of cooperation evolution.
