There was an actual study that measured the level of disgust one registered when tasting something bitter and when faced with the morally acerbic. They found that the 2 sitiations registered an equal amount of grossicity.
There were 4 studies done and in the first 2 scientists measured reactions to typically nasty things like poop and dirty toilets, which are -GAHH! In the second they measured things that were morally disturbing like the splitting of 10$ unfairly. I wonder what other morally disturbing things they came up with.
Scientists stuck electrodes onto the muscle that curls the upper lip and wrinkles the nose in disgust (levator labii superioris alaeque nasi – say that 5 times fast! ) to determine when and how someone would react.
The good news in all of this is that men and women measured about the same. What’s gross is gross!
