Edit: I do think it is true that the words are correlated somehow, but I also think it is true our thoughts about the nature of that correlation are likely to be pareidolia. In this lecture by Sam Harris, around the 22:00 mark, he talks about how many studies have given us evidence that our stories about why we think what we think or why we did what we did are NOT correct - they are post hoc fabrications of the left hemisphere of the brain trying to make sense of things it doesn't understand (ie the subconscious).
