Henri Tajfel
social-psychology · 1919-1982 · Poland / United Kingdom
Henri Tajfel, a survivor of the war whose family did not survive it, spent his career on a hard question: how little it takes for people to divide into us and them. His minimal-group experiments gave a stark answer — mere categorization, with no history or stakes, is enough to produce in-group favoritism — and grounded social identity theory's account of how we draw self-worth from the groups we belong to.
What Vela reads them for
Tajfel is the experimental voice behind Vela's reading of the Galatians conflict and other moments of communal boundary-drawing — the machinery of group formation underneath a theological dispute. His concept page is in-group/out-group dynamics, which pairs with collective effervescence and moral foundations theory.
Concepts they originated
Honest framing
The minimal-group effect is robust, but the leap from lab categories to real ethnic and religious conflict is a leap, not a proof. Vela reads it as a mechanism that is present, not as the whole story of any division.
