One of the problems associated with statistical correlations is the correct assignment of causality. The obvious one may not be the actual one. As an example, in the 1960's someone ran a correlation of the angle of toe-out of women's feet with age. There was a distinct tendency for older women to toe-out more than younger women.
It turned out that in an earlier age women were encouraged to walk toeing out. The practice faded away with time.
We see this rush to causal assignment often in pop psychology. Or in political attempts at assassination through association. ['Did you know that So-and-so lived next door from You-know-who in 19-- ? Where there's smoke, there's fire, folks!']
