Don't flatter yourself: Why survey research can be flawed
We all do things to impress others-exaggerate our accomplishments, downplay our faults, even fib on surveys. A new study in the Journal of Consumer Research sheds light on why we don't tell the strict truth about ourselves in surveys and what, if anything, can be done about it. view more (2009-02-24)
