For example:
This statement is intentionally misleading, trying to get people to draw the conclusion that tall kids have higher IQ. What they do not talk about is the likelyhood that since people grow at different rates and different times, the taller kids may simply be more developed (both in terms of height and in terms of brain development). That could easily explain the different on cognitive tests, but that would be boring.
