From the wikipedia page it seems to be a generalization on sampling below the Nyquist frequency can lead to incorrect
interpretation of wave forms but in more dimensions.
The argument here is that "smart people are worse looking" is actually a case of _of the people you encounter_ smart people are worse looking, but that overall there is no correlation. This makes sense, but I think it's more complex. If you took the entire population, I think you could still conclude the "smart people are worse looking" if you define smart to include non-innate, learned behaviour, for the simple reason that good looking people have an easier time in life (getting jobs and so forth) and are therefore less compelled to spend time and effort becoming "smart". So there's a self-balancing aspect that produces these correlations in the general population as well.
