Importantly, even where a very spare analysis which gets to pick and choose its terms and data (i.e. any analysis which begins by frontloading (1) measured - actually etimated - IQ and the traditional and (2) unanalysed markers by which success is judged) finds that there is a crude regularity whereby IQ and success are correlated, in practical terms nobody will ever - and I mean EVER - use this data to support conclusions which follow from the discovery of a crude regularity. This is partly a human cognition thing and mostly an ideology thing, but the human cognition thing is an important cause. It’s very difficult, practically impossible, for people not to move from a continuous result (the crude regularity) to a categorical conclusion (one which parses between individuals) - and fortunately, for the bigot, this already plays into the bigoted attitude.
