There is a new explanation why people are more likely to keep drinking, even after you have a night like the guy in the above picture, because you are more likely to remember the positives when drinking instead of the negatives. A study done by psychologists at the University of Washington who interviewed 500 college students found that the students believed that the positives from drinking were more likely to occur in the future than the negatives (I don’t know if interviewing just college students proves this theory at all, but hey, it was done by psychologists so it has to be right).
