Does thinking you’ve had a drink make you feel prettier?
“Beauty is in the eye of the beer holder”: People who think they are drunk also think they are attractive
People who only thought they had been drinking rated themselves as more attractive.
Ig Nobel 2013
Participants in a bar-like setting were given either alcoholic or non-alcoholic drinks, and told either the truth or the opposite. Then they recorded a short ad and rated their own attractiveness.
Believing you had been drinking, whether you had or not, made people rate themselves as more attractive. Independent judges did not agree.
The confidence was the placebo all along.
