Every once in a while a person or publication will try to rank the most influential people in the field of psychology, past and present. Inevitably each list delivers different results, so we want to bring the question to you. Fromm? Freud? Frasier? Who gets your vote? Is there a place on the list for popular culture? We would love to hear who you think is the most influential person in the history of psychology and why. Please comment.
