The sudden buzz of a fly has most people flapping their hands wildly as if attempting to ward off an evil spirit. Seeing a wall or ceiling-hugger has others running quickly past or under, as if their mere shadow might prompt the insect to launch an aerial attack. Still others pick the fight response, choosing to squash the danger. But here’s the bug-zillion dollar question: Why do creepy-crawlies cause us to react this way? A 2018 Georgia Tech study that included Eric Schumacher, professor in the School of Psychology, found that the strongest neurological reaction elicited by bugs is disgust. It’s a result borne of a mix of things, from social conditioning and negative connotations to understanding their disease-carrying potential and, unfortunately, judging the book by its spindly, slimy, antennaed cover.
