Thank you for the references, upvoted. But it's not clear to me that "finding babies uncute" has actually been linked to psychopathy per se, albeit it might be something interesting to investigate because of a couple of chained correlations. In fact the term "fairly strong evidence" in the original comment does seem misplaced, unless you know of a specific experiment indicating that.

(Also, would "fairly strong evidence" in this context mean say "a likelihood factor of ten for finding babies uncute, even though the base frequency of psychopaths is low" or "a substantial fraction of people who find babies uncute are in fact psychopaths"?)
