A group of researchers from Cambridge University have learned to predict the level of intelligence of a person by his photos in social networks.
First, scientists selected a group of users with low performance IQ and analyzed their pictures. Able to identify group specific characteristics. Among them were photos on the front camera phone and the photos with the ridiculous glasses on his face.
People with a high IQ approach to choosing photos for social networks more systematically and responsibly. Most often, the pictures were they are alone, no weird plots and extraneous objects in the frame.
Note, talking about unconditional veracity of a study is not necessary. Too small a sample of volunteers was used in the research work.
