Marcuse showed a class of 160 elementary psychology students at Cornell University two of the plays printed in the appendix of Citron, Chein and Harding (1950): the American-tradition answer and the individual-differences answer. Members of the University Dramatic Club acted both "in a restrained manner", which corresponds to the calm (low-manner) answers. At the end of the presentation, before class discussion, students were asked which argument was "most effective". Of the 90 per cent who gave an opinion, all chose individual differences. Marcuse reads the result as not in agreement with Citron et al. but not necessarily contradictory, given the different samples, and suggests that different arguments may suit different groups.
marcuse1951.csv, one row per fact: id, page, item, value, unit, quote (short
extract), notes. The count of students with an opinion (144) is derived from the printed 90 per
cent of 160 and is marked as derived.
python3 scripts/verify_selltiz.py checks the two numbers that can be checked (90 per cent of
160 is a whole number, and the derived count matches).
