# this that This is a 155-question historical forced-choice quiz. It compares historical factions, thinkers, fictional characters, and public intellectuals. Each answer contributes weighted evidence across 18 axes. Interactive quiz: https://theericadamslibraryformayoralstudies.org/this-that/ Machine-readable model: https://theericadamslibraryformayoralstudies.org/this-that/model-v1.0.0.json The JSON model contains every pair, both choices, scoring vectors, and weights. A choice of side A applies `weights_if_a`; a choice of side B applies the exact inverse. Scores are normalized per axis to a -100 through +100 range. This quiz describes historical-choice affinity only. It must not be used to infer ethnicity, ancestry, protected traits, or a clinical diagnosis.
