- whatshisface 5y agoI guess that inspires another take: - Suppose performance in the school system has an upper limit slightly above average, but no lower limit. Then anything that increases the variance of one group, whether innate ability or environmental effects, will show up as a fall in the group's average, because the growth in the high end of the curve is disproportionately not being measured, while the growth in the low end is.
