Okay. Well. I got the study. Oh dear.
They compared people with "high IQs" to others. They didn't actually define "high IQ." But they
did write the following:
Analyses removing scores below the 5th and above
the 95th percentile ruled out undue influence of extreme
scores on the results.
This means they cut out any IQ score above 124. So they wanted IQ scores that were high but not
too high.
When I couple this with the fact that they didn't provide a range or even an average for their high IQ category, I feel dubious. If they removed people with IQs at least ~1.5 SD above average and then didn't define "high IQ" in the ones who remained, how can anyone draw conclusions about their claims? Any interpretation of
high IQ here is arbitrary, beyond the fact that in this study it was, at best, "above average."
PM me if you want a copy of the paper.
