Praise and Positive Reinforcement
If you’ve ever thought the pop psychology on self-esteem had the causal arrow pointing in the wrong direction (e.g., self-esteem and success are correlated, so if I praise a kid up the wazoo, I increase his/her changes of being successful), read this and feel vindicated. Money quote:
After reviewing those 200 studies, Baumeister concluded that having high self-esteem didn’t improve grades or career achievement. It didn’t even reduce alcohol usage. And it especially did not lower violence of any sort. (Highly aggressive, violent people happen to think very highly of themselves, debunking the theory that people are aggressive to make up for low self-esteem.) At the time, Baumeister was quoted as saying that his findings were “the biggest disappointment of my career.”
Now he’s on Dweck’s side of the argument, and his work is going in a similar direction: He will soon publish an article showing that for college students on the verge of failing in class, esteem-building praise causes their grades to sink further. Baumeister has come to believe the continued appeal of self-esteem is largely tied to parents’ pride in their children’s achievements: It’s so strong that “when they praise their kids, it’s not that far from praising themselves.”
By and large, the literature on praise shows that it can be effective—a positive, motivating force. In one study, University of Notre Dame researchers tested praise’s efficacy on a losing college hockey team. The experiment worked: The team got into the playoffs. But all praise is not equal—and, as Dweck demonstrated, the effects of praise can vary significantly depending on the praise given. To be effective, researchers have found, praise needs to be specific. (The hockey players were specifically complimented on the number of times they checked an opponent.)
