Single online social-value-orientation (SVO) experiment with N = 697 Prolific participants across two phases. In Phase 1 (decider), participants made 18 choices between payoff allocations labelled prosocial/individualist/competitive; in Phase 2 (recipient), they predicted which of two options a partner would choose over 36 trials with correctness feedback, then rated the partner's harmful intent (HI) and self-interest (SI) and completed paranoia (R-GPTS) and cognitive-ability (ICAR) questionnaires. The research question is how people integrate priors about others into Bayesian belief updating about a partner's social preferences, whether one's own SVO shapes these priors, and whether participant-partner preference alignment improves prediction accuracy and reduces attributions of harmful intent. Responses are 1/2 option choices in both phases.

The points you earn are pooled over a series of tasks and contribute to an overall total that enters a financial lottery. PHASE 1 - DECIDER. You are the decider.
