    Summary
    This summary is machine-generated.

    Groups take greater risks than individuals, even when aggression is involved. This finding challenges the risk-as-a-value theory and supports the diffusion of responsibility hypothesis in group decision-making.

    Area of Science:

    • Social Psychology
    • Group Dynamics
    • Decision-Making Behavior

    Background:

    • Previous research indicates a "risky shift" phenomenon where group decisions are riskier than individual ones.
    • The applicability of this "risky shift" to situations involving aggression remains less understood.

    Purpose of the Study:

    • To investigate if the "risky shift" extends to group decisions involving both risk and aggression.
    • To compare risk-taking levels between individuals and groups in a high-consequence scenario.

    Main Methods:

    • A between-subjects experimental design was employed.
    • Participants were exposed to a task with severe noxious consequences, either individually or in unisex triads.
    • Risk-taking behavior was measured in both individual and group conditions.

    Main Results:

    • Both male and female groups demonstrated significantly greater risk-taking than individuals.
    • This effect persisted even when risk-taking was mediated by aggressive means.
    • Group risk-taking was consistently higher across both sexes.

    Conclusions:

    • The findings suggest that group influence on risk-taking is robust, extending to aggressive contexts.
    • The results challenge the "risk-as-a-value" hypothesis, which may not fully explain group risk-taking.
    • The "diffusion of responsibility" hypothesis provides a more consistent explanation for observed group behavior in risky and aggressive situations.
