Trypophobia, an aversion to clustered holes or bumps, triggers discomfort in about 16% of people, according to psychologist Geoff Cole. Although not officially recognized in the DSM, common triggers include lotus seed pods and honeycombs. The evolutionary roots remain unclear, with theories suggesting a link to poisonous animals or diseases. Coping strategies involve exposure therapy and cognitive-behavioral techniques. Cole recommends gradual exposure to help desensitize the fear response. In conclusion, trypophobia is a prevalent, unofficial phobia, and understanding its triggers can aid in developing effective coping mechanisms for those affected.
