Scar Experiment (Robert Kleck, Dartmouth University)
Participants (27 male, 21 female) were told that the experiment was meant to observe if people behaved differently towards those with facial scars.

Participants were placed into rooms with no mirrors

A make-up artist proceeded to draw a scar on their face

After the scar was drawn, participants were given a short glimpse of it with a pocket mirror.

Participants were then invited to leave the room and interact with folks in the building.

Before they left the room, the make-up artist told the participants that the scar needed some final touch-ups. But, what the make-up artist actually did next was to wipe off the make-up of the scar.

Participants left the room thinking they still wore a make-up scar.

They overwhelmingly reported back that people stared at their scars, and were mean and rude to them.
