Disgust is not a universal hardwired emotion

Disgust is not a brute hardwired fact of human evolution; what is universal is nausea and vomiting (functional capacities also seen as freezing, running, fainting), while humans use their abstraction capacity to label perceptually and motorically different events as 'disgust.' Disgust 'lives' in the perceiver who categorizes, not in the event, and in small-scale remote cultures Barrett's lab saw nothing that looks like disgust.
