The Yuck Factor
We’re talking about disgust, about what grosses us out, and why this is a reflex that’s hardwired deep within the human psyche. Does the scent of spoiled milk make you wince? Does the sight of maggots and mold have your stomach doing summersaults?
In That’s Disgusting: Unraveling the Mysteries of Repulsion, psychologist Rachel Herz takes on the science behind the things that make as gag, grimace, and recoil. There’s a reason why the things that ooze and wriggle and reek creep us out. They signal decomposition, contamination, and disease. Disgust is a survival mechanism that tunes us in to the threats that can do us in.
