consistent judgements and such judgements are associated with MI for both men and women

images is a difficult task even for humans, but it is possible to equal humans’ accuracy using algorithms while also having the potential to reduce biased judgements.

High MI & high PI
and images are usually less diversified in colour, more clear in texture, and contain less skin area High MI
but this does not affect how others judge them

Intelligent people understand that a profile picture is most effective when it shows single person, captured in focus, and with an uncluttered background

High MI & high PI
images are usually less diversified in colour, more clear in texture, and contain less skin area High MI
does not affect how others judge them Inaccurate stereotypes-correlated with PI but not MI:
higher chromatic purity, smiling and wearing glasses, and faces at a proper distance from the camera, make people look intelligent no matter how smart they really are
