Can a third of "ear-wiggle" people move one ear?

People vary in how much control they have over their auricular muscles: they may move both ears together or predominantly one. In a 1995 study, about 22% of participants could move one or the other ear and about 18% could move both simultaneously. It does not establish a simple “one-third of ear wigglers can move one ear” rate for the general population; categories and assessment methods matter. The one-third figure should not be presented as a precise population fact.
