Out of 30 faces, you correctly identified 18.You were familiar with 21 of the people in this test.
If we exclude the
ones you were unfamiliar with, you got 86% correct.
I was surprised by how this test was conducted. I believe if a person watches enough television/movies they would be better at this test than someone who does not. I was also surpised by how many faces I was not able to correctly identify. It was a fun test, but I dont believe it would be an accurate way of detecting face blindness in the average person.
