How Situational Settings Influence Behavior: New Insights from Behavioral Research

What is it about?

Walter Mischel proposed in the 1970s that strong situations—those with clear rules and expectations—reduce variability in behavior. While widely accepted among psychologists, this idea lacked consistent support. We thus designed a study to test the claim systematically. Specifically, we analyzed prosocial behavior in social dilemma games (e.g., prisoner's dilemma, public goods game), aggregating over 300 effect sizes from 25,000 participants using data from the Cooperation Databank. Our findings confirm that strong situations lead to more uniform behavior, reducing variability. We explored how psychological mechanisms like reinforcement learning, social norms and reputation concerns, and (reduction of) cognitive dissonance shape these outcomes.

Why is it important?

Our study stands out for its innovative design, scale, and rigorous, tailored analyses. By employing a meta-analysis of variance, we addressed a long-standing debate in psychology and beyond on how strong situations influence behavior. With rising interest in how context and psychological situations shape human behavior, our findings provide valuable empirical evidence. This research has implications not only for personality science, social psychology, behavioral economics, but also potentially for policy-making aimed at nudging desired behavior. Prosocial behavior in economic games closely mirrors real-life cooperation, such as citizen compliance behavior such as paying taxes or altruistic acts like blood and organ donations. Understanding how situations shape behavior, particularly in cooperative contexts, can lead to more effective interventions and policies that encourage prosocial actions while minimizing undesired behaviors.
