The emotion of disgust has six basic triggers

Susan Scutti at CNN:

“Disgust evolved to protect us from disease in our ancient past. The disgust response today may, or may not, be a good guide to what might make us sick today,” said Val Curtis, lead author of the study and a professor and director of the Environmental Health Group of the London School of Hygiene & Tropical Medicine.

“It is unlikely to be a coincidence that many of the stimuli that elicit the emotion of disgust in humans are also implicated in the transmission of infectious disease,” Curtis and her co-author, Mícheál de Barra, a lecturer at Brunel University London, wrote.

To better understand disgust, Curtis and de Barra recruited more than 2,500 participants through advertisements on social media and psychology websites for an online survey. They checked IP addresses to control for the possibility of multiple survey entries from a single participant.
