Your daily dose of gloom.  Dr. Charlton is seen, and raised.

This ‘letter’ to Greg Cochran from three years ago is relevant:


GC incrementally *seems* to have almost entirely come-round to what I was saying then – although he doesn’t say so. He apparently still regards my estimate that c.150 years ago the average English intelligence (‘g’ or general intelligence) was about 1 SD higher than now as excessive – apparently because Greg feels that top-level intellectual attainment now is not much different from then (whereas I perceive a massive decline in creative geniuses – both in quantity and quality).

1 standard deviation is about 15 IQ points – but I think IQ testing *performance* (and perfomance in similar tasks requiring concentration, clear consciousness etc) would have been lowered in the old days by high prevalence of endemic disease, malnutrition and illness.

@Bruce, thanks for the update.

I saw Cochran’s post a few days ago, and had half a mind to mention that he seemed to be moving toward Woodley/Charlton when he had been so obnoxiously dismissive before. But every other time I’ve commented there even just to ask a clarifying question, I’ve been beset by Cochran-worshippers who won’t abide any questioning. Who needs the trouble?
