Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

Talib is insufferable as always and brings lot of his pet obsessions into the discussion but this is damning enough:
IQ is largely a pseudoscientific swindle - INCERTO - Medium
Additional Variance: Unlike measurements of height or wealth, which carry a tiny relative error, many people get yuugely different results for the same IQ test (I mean the same person!), up to 2 standard deviations as measured across people, higher than sampling error in the population itself! This additional source of sampling error weakens the effect by propagation of uncertainty way beyond its predictability when applied to the evaluation of a single individual. It also tells you that you as an individual are vastly more diverse than the crowd, at least with respect to that measure!

IQ is largely a pseudoscientific swindle - INCERTO - Medium

There are contradictory stories about whether IQ ceases to work past a threshold, since Terman's longitudinal study of "geniuses". What these researchers don't get is these contradictions come from the fact that the variance of the IQ measure increases with IQ. Not a good thing.

IQs a bust.
