Quizplus · Accepted Answer

Both universal recognition of facial expressions and the observation of blind persons' facial expressions support Ekman's argument that primary emotion facial expressions are innate. The fact that people who are blind from birth also make the same facial expressions for the same emotions as sighted individuals suggests that these expressions are not learned through observation and must have a biological basis. Additionally, the cross-cultural recognition of these expressions further supports their innate nature. Factor analysis may be useful in categorizing and identifying different emotions, but it does not provide evidence for their innate biological basis.
