The document critically examines the common assumption that high self-esteem leads to numerous positive outcomes, including better performance, happiness, and healthier lifestyles. It finds that the evidence for high self-esteem being a direct cause of these benefits is weak, and often, self-esteem is influenced by other factors such as actual success rather than being a primary motivator. The authors recommend caution in promoting self-esteem interventions, as boosting self-esteem indiscriminately can sometimes lead to narcissism and other negative consequences.
