Summary
A balanced defense/critique of the IAT that lands a genuinely original reframe. Defense: it picks up control associations (flowers/insects, Japanese/Korean), resists faking, retests at ~.6, and predicts some behavior. Prosecution: poor individual retest reliability (fine for populations, embarrassing for individuals) and Tetlock/Arkes's point that negative scores may reflect shared cultural stereotypes, non-prejudiced cognition, or even rational responses — not personal animus. Scott's stance is 'moderate believer,' stressing you can't hand someone an IAT and call them racist (beliefs come in levels — the dragon-in-the-garage, the skeptic afraid of haunted houses), and that 'racism' is a bad word that lumps Hitler with a man who feels a late-night pang of fear. The standout move: the IAT measures distance in thingspace, not racism — pairing white+good / black+bad is a natural category like reuniting East and West Germany, while white+bad / black+good is as arbitrary as merging East Germany with South Vietnam into 'Southeast Vietnermany'; the IAT just measures which coalition coordinates better. Caveat the post predates: the IAT's individual predictive-validity literature has weakened considerably since 2009, so the 'moderate believer' stance is shakier than it reads — though the thingspace reframe, the post's real contribution, doesn't depend on it.
Why this score
Quality 74 · Strong. Strong — the thingspace reframe (IAT as a measure of category-distance, via the memorable Southeast-Vietnermany analogy) is an original, illuminating contribution, and the multiple-levels-of-belief and taboo-'racism' points are sharp and balanced. Held at 74 (and Med confidence) because it stakes a moderate-believer position on a test whose individual validity has since been seriously contested — but the conceptual reframe carries the score regardless.
Claude’s paradigm shift 50 · Moderate. Notable — recasting the IAT as a thingspace-distance instrument rather than a racism-detector is a fresh, generative 2009 reframe.
Real-world impact 2 · Minor. A balanced IAT defense/critique that lands an original 'thingspace' reframe (the test as a measure of category-distance, via the Southeast-Vietnermany analogy) plus the multiple-levels-of-belief point. Conceptual influence within rationalist discourse, no material change — low RWI.
