Pedantic, but average IQ scores have stayed the same over the years, exactly 100.

- pizza 9y agoThis is always the case after they adjust the test. But the averages of generations can differ over time if they use the same test/sans adjustment. But there is a much stronger way to believe IQ is not the same over time : intelligence is not normally distributed, at all. It really is meaningless to try to measure intelligence samples and call them independent and identically distributed random variables, whether the 'population' is an individual at one snapshot or over time, or an individual in a group (whether over time or not). Intelligence is probably better measured by a power-law distribution than the normal distribution, whose key property is that it is the probability distribution that maximizes entropy/minimizes information. So maybe there would be a larger discrepancy (relative entropy aka Kullback-Leibler divergence) in measuring IQ as a normal distribution over time than expected (maybe that's the whole reason for the Flynn effect and the author writing this article..)
