He has also served as an associate editor of the Journal of Personality and Social Psychology and is currently the Executive Officer of the Society for Personality and Social Psychology. 

His work focuses primarily on the accuracy with which people view themselves and their peers. In his most widely-cited research, he showed that people tend to hold flattering opinions of themselves and their decisions that cannot be justified from objective evidence, work that has been featured in numerous newspapers (e.g., New York Times), magazines (e.g., U.S. News & World Report ), radio (e.g., National Public Radio), and television (e.g., CBS Early Show). It has even been mentioned in a Doonesbury cartoon. 

This work on the self has been supported financially by the National Institute of Mental Health and the National Science Foundation, and was recently reviewed in his book Self-insight: Roadblocks and detours on the path to knowing thyself (2005, Psychology Press). 

He has also published work on eyewitness identification, depression, motivated distortion in visual perception, stereotyping, and behavioral economics.
