    Area of Science:

    • Social Psychology
    • Game Theory
    • Organizational Behavior

    Background:

    • Existing coalition formation theories lack generality, failing to predict outcomes broadly or in diverse conditions.
    • A need exists for a more comprehensive model applicable across various group decision-making scenarios.

    Purpose of the Study:

    • To propose and validate a general model for coalition formation in group decision processes.
    • To offer a predictive framework that overcomes the limitations of current theories.

    Main Methods:

    • Development of a novel model for coalition formation.
    • Empirical validation through comparisons with existing studies across different coalition paradigms.

    Main Results:

    • The proposed model demonstrates considerable empirical support, accurately predicting observed coalition patterns.
    • The model proves effective in a variety of situations, enhancing predictive generality.

    Conclusions:

    • The new model provides a robust framework for studying coalition formation processes.
    • It allows for the examination of situational factors influencing coalition dynamics, despite some ambiguities.
