Understanding trypophobia: Why clusters of holes cause fear and disgust

Trypophobia causes strong aversion to clusters of holes, linked more to disgust and fear than actual threat. Researchers suggest this reaction may stem from evolved disease-avoidance instincts, as the brain misinterprets harmless patterns as signs of parasites or infection. While not a formally recognized phobia, an estimated 10-18% of the population experiences discomfort from these visual triggers.
