Abstract: Traditional researches considered that self-esteem was positively correlated with self-serving biases, and that those people with high self-esteem had stronger self-serving biases than those with low self-esteem. But more and more researches put forward challenges of this conclusion. These researches mainly related to two questions: (1) whether did only people with high self-esteem have self-serving biases? (2) whether did every person with high self-esteem have self-serving biases? It is pointed out that future researches should study these two questions more deeply and more detailed, for example, which people with what kind of self-esteem have self-serving biases, whether self-serving biases are only a kind of strategy and it is good or bad, etc

Key words: self-esteem, self-serving bias, self-enhancement
