Here are some of our disappointing findings. High self- esteem in schoolchildren does not produce better grades. (Actually, kids with high self-esteem do have slightly better grades in most studies, but that's because getting good grades leads to higher self-esteem, not the other way around.) In fact, according to a study by Donald Forsyth at Virginia Commonwealth University, college students with mediocre grades who got regular self-esteem strokes from their professors ended up doing worse on final exams than students who were told to suck it up and try harder.
There were a few areas where higher self-esteem seemed to bring some benefits. For instance, people with high self- esteem are generally happier and less depressed than others, though we can't quite prove that high self-esteem prevents depression or causes happiness. Young women with high self- esteem seem less susceptible to eating disorders. In some studies (though not all), people with high self-esteem bounce back from misfortune and trauma faster than others.
High self-esteem also promotes initiative. People who have it are more likely to speak up in a group, persist in the face of failure, resist other people's advice or pressure and strike up conversations with strangers. Of course, initiative can cut both ways: One study on bullying found that self-esteem was high among the bullies and among the people who intervened to resist them. Low self-esteem marked the victims of bullying.
