Podsumowanie	The Social Relations Model (SRM), developed by David Kenny and colleagues, is a variance-decomposition framework for analyzing interpersonal perception and behavior in groups. When every member of a group rates (or behaves toward) every other member in a round-robin design, each rating reflects three distinct sources: the perceiver's general tendency to see others a certain way (actor effect), the target's general tendency to be seen that way by others (partner effect), and the unique adjustment a particular perceiver makes for a particular target (relationship effect), plus error. The SRM partitions the total variance into these components and estimates two kinds of reciprocity -- generalized (do people who like others tend to be liked?) and dyadic (do specific pairs uniquely reciprocate?). By separating the perceiver, the target, and their unique relationship, the SRM answers fundamental questions about whether interpersonal judgments lie in the eye of the beholder, the qualities of the person judged, or the chemistry of the dyad.	The minimal group paradigm is an experimental procedure, introduced by Henri Tajfel and colleagues in 1971, that strips intergroup conflict down to its barest possible cause: mere categorization. Participants are sorted into two groups on a trivial or random basis (for example, an alleged preference for one painter over another, or a coin toss), never meet other members, gain nothing personally, and then allocate points between anonymous in-group and out-group members using structured reward matrices. The striking and repeatedly replicated finding is that people favor their own group even when the category is meaningless and favoritism brings them no material gain. The paradigm became the empirical cornerstone of social identity theory, demonstrating that the cognitive act of dividing the social world into 'us' and 'them' is itself sufficient to produce discrimination.
