There are many memes like this where someone with a good background in science will suggest upon reading an obscure evo psyche or dev bio paper that some biometric is a strong indicator of a myriad of complex behavioral traits in an individual, years pass, meme spreads, paper is examined by the field and determined to be wanting in evidence, original promulgator forgets about, ceases to care about, or rejects previous casual assertion, idiots and parrots continue to chase dead end.
