Jean Lave
American social anthropologist (1939–2023) whose ethnographic fieldwork in Liberian tailoring workshops and Orange County supermarkets produced the most rigorous empirical challenge to the cognitivist model of mind — and the theoretical framework most directly relevant to the AI transition.
Jean Lave was an American social anthropologist whose four decades of fieldwork fundamentally reshaped how scholars understand the relationship between cognition and context. Her early research among Vai and Gola tailoring apprentices in Liberia in the 1970s documented how newcomers acquired mastery not through formal instruction but through gradually deepening participation in the everyday practice of their craft. Her landmark studies of adult arithmetic in American supermarkets and kitchens demonstrated that the same individuals performed radically different mathematics in practical settings than in formal testing environments.

Lave held faculty positions at the University of California, Irvine and then at UC Berkeley, where she spent the majority of her career in the Department of Geography — an unusual institutional location that reflected her insistence that cognition is irreducibly situated in
