We've all heard of the folk belief that as individuals (especially men) become inebriated, they increasingly find others more attractive (as compared to when non-intoxicated). See the following beer commercial that captures the phenomenon in a very humorous manner.

Two studies have tested this proposition and arrived at one similar conclusion and one important difference. In a 2003 paper published in Addiction, Barry T. Jones, Ben C. Jones, Andy P. Thomas, and Jessica Piper approached men and women who had either consumed a certain amount of alcohol on that day or had not consumed any alcohol. They showed them numerous photos of men and women and asked them to rate these (in terms of their attractiveness). The alcohol effect was obtained albeit solely for opposite-sex photos. In other words, men who had consumed alcohol provided higher ratings for women's photos (than their non-alcohol male counterparts). The same occurred with the female participants (when rating the facial attractiveness of male targets).
