Hmmm, I don't think I saw any other languages besides Spanish and English, is this really a universal effect across languages? I am especially curious because I am inclined to believe that certain sounds are not distributed the same in all languages. This could mean that either this theory is untested on a broader set of languages, or that the typical vernacular in a language tends to avoid a certain type of word more than other languages.
