Intoxication and its effect on the perception of beautyFeatured science projectScience project video


This science fair project was performed to find out how our perception of beauty can be affected by intoxication. The tests were done by asking participants to rate the attractiveness of members of the opposite sex in photos before and after getting intoxicated.


The participants will rate the attractiveness of members of the opposite sex more highly after getting drunk.

Scientific Terms

Beer goggles, intoxication


Beer goggles

After drinking alcohol, a person may experience what is known as “beer goggles”, where he or she suddenly finds others more attractive than they did before. A person may start out looking unattractive, but as the evening progresses, he or she may begin  to appear to be more attractive as the onlooker consumes more alcohol.

Normally, a sober person will be cautious and hesitate to approach a member of the opposite sex for fear of being rejected. However, as they consume more alcohol, their inhibition starts to disappear, together with their fear of being rejected. Suddenly, they become very sociable and the people around them start looking more attractive than they did before.

People’s ability to judge symmetrical and attractive faces becomes poorer after they become intoxicated. The more drunk they become, the less they seem to care about or even notice the minor defects in the faces that they are looking at.
