Lore-abiding people. [Review of: Kusch, Martin, Psychological knowledge: a social history and philosophy. Routledge, 1999].

I evaluate Kusch's arguments that everyday and scientific psychological benefits are made true by the institutional facts about the people to whom they are applied. I conclude that institutional facts are among the truth-makers of such beliefs, and that this is a very significant point to have made, but that they are unlikely to be the sole such truth-makers.
