Self-Reported GPA and SAT: A Methodological Note. - Practical Assessment, Research & Evaluation

The use of self-reports from students is a common, yet risky, methodological venture in psychological research. Relying upon an individual to provide an accurate and unbiased rating of her or his ability, attitude, or past experiences is problematic, considering that the behavioral revolution in psychology was driven in part by a rejection of the reliance on malleable data sources. Researchers now concentrate on observable phenomena that can be validated; however, they are often forced to ask participants to provide various forms of data without having the means to verify their accuracy.
