Judging a book by its cover: Can one see how smart people are from pictures alone?
We want to found out how good people are at judging intelligence from pictures of people. The best way to do this is to have a set of pictures of people and their IQ scores. These pictures should ideally be normalized. We didn't have such pictures, but attempts were made to find a picture with a normal facial expression, and with people looking into the camera. More information here.
Here are 14 pictures of people. For each person, try to guess how smart s/he is. The guess should be in IQs (mean=100, sd=15). Send the results to my email: firstname.lastname@example.org.
The sample below has the following stats: 122 is the average IQ. SD is 13.
