Naturally, there is the flip side to the sensory disgust phenomenon—sugary (versus salty) snacks make subjects rate themselves as more agreeable and helpful individuals and rate faces and artwork as more attractive.[5] Ask a subject, Hey, in last week’s questionnaire you were fine with behavior A, but now (in this smelly room) you’re not. Why? They won’t explain how a smell confused their insula and made them less of a moral relativist. They’ll claim some recent insight caused them, bogus free will and conscious intent ablaze, to decide that behavior A isn’t okay after all.
