High and low performers felt fine when they assessed themselves accurately, probably because the high performers recognized their strengths and low performers acknowledged their weaknesses and could try to improve their future performance. The study, "Emotional Costs of Inaccurate Self-Assessments: Both Self-Effacement and Self-Enhancement Can Lead to Dejection," was published in the October issue of the APA journal Emotion.
"These findings challenge the popular notion that self-enhancement and providing positive performance feedback to low performers is beneficial to emotional health. Instead, our results underscore the emotional benefits of accurate self-assessments and performance feedback," said lead author Young-Hoon Kim, PhD, of the University of Pennsylvania.
The study involved experiments with four different groups of young people from the United States and Hong Kong. Three U.S. groups totaled 295 college undergraduates and one Hong Kong group consisted of 2,780 high school students.
In the first two experiments, one of the U.S. groups and the Hong Kong students took academic tests and were asked to rate and compare their own performances with other students at their schools. Following their assessments, all the participants completed another widely used questionnaire to assess symptoms of depression.
In the third and fourth experiments, researchers evaluated the other two sets of U.S. undergraduates with feedback exercises that made high performers think their performance was low and low performers think their performance was high.
Across all the studies, results showed that those who rated their own performance as much higher than it actually was were significantly more likely to feel dejected. "Distress following excessive self-praise is likely to occur when a person's inadequacy is exposed, and because inaccurate self-assessments can prevent self-improvement," said co-author Chi-Yue Chiu, of Nanyang Technological University in Singapore.
