The Material Force of Categories

Co-organiser of symposium with Sasha Bergstrom-Katz

Date: 11 March 2023
Institution: Birkbeck, University of London

This symposium, organised in parallel to the Psychotechne exhibition, examined how assessment and categorisation can play an active role in decision-making structures. The event explored how socio-technical systems produce categorisations—particularly categorisations of intelligence, risk, and the subject—in ways that can then be operationalised within broader institutional and epistemic frameworks. The symposium was interested in how such categories are produced through a range of psychosocial, statistical, and technical modes of assessment, including psychometric and psychological testing, risk assessment tools, and machine learning.

Speakers included Ramon Amaro, Margarita Aragon, Anthony Faramelli, Eoin Fullam, Becka Hudson, Simon Jarrett, and Ageliki Lefkaditou.
