Scott Douglas Jacobsen asks why ordinary bodily noises irritate us. Rick Rosner frames the reaction as evolutionary triage: humans quickly judge reproductive fitness, triggering instant attraction or the ick. Aversion to lip smacking, grunting, and loud chewing may signal traits like poor hygiene or impulsivity, maladaptive in mate choice. Disgust toward feces, blood, and exposed anatomy protects against disease and injury. Visible reminders of internal bodies, like open-mouth chewing, amplify repulsion. We also assess non-targets as competitors, and unease around extreme old age reflects selection pressures minimizing misdirected sexual interest. The interview explores instinct, culture, and biology behind everyday irritation.
