Contemplating the important questions at Alpha Game:
You can always trust a smart, unattractive man in the mold of Isaac Asimov to leap with certainty to the wrong conclusion when women are concerned. Just as you can trust a young woman to have no idea what it is that is tripping her attraction triggers. Granted, Asimov himself knew better – hence his joke about growing his ears out – but men are as deluded about the sex appeal of intelligence, honor, godliness, sincerity, and dedication as women are about educational degrees, snark, and being gainfully employed.
Intelligence is a useful DHV when a man is already considered attractive, but his intelligence is not why Spock was considered dreamy by women. After all, Scotty was plenty smart too and women didn’t think he was dreamy.
