The term trypophobia was coined in 2005 by internet users that merged the Greek words for hole and fear. While it is yet to be officially defined as a condition, a study in Psychological Science has estimated that trypophobia is present in 16 per cent of people. The academic paper explains that the condition provokes an intense reaction, even though βthe stimuli are usually clusters of holes of any variety that are almost always innocuous and seemingly pose no threat.β The severity of the fear ranges on a case to case basis. While some find that clusters of holes causes them feel uncomfortable, others have claimed that the sight of the images can make them shake all over in fear.
