Categorisation, Comparison and Cases
summary
Argues the common folk theory of categories is wrong and replaces crisp sets with prototype membership and gradients, shows experiments where robins are typical birds and penguins are subordinate, demonstrates non-transitivity with car seats chairs furniture, gives a tomato as 70% vegetable 30% fruit example and lists a dozen overlapping Norwegian welfare definitions for cohabitation, warns that technifying categories for software accumulates assumptions like sandbags in a Tetris game, and urges deliberate modeling because edge cases are normal.
