There are many paths to success, but the significance of grit in helping you reach that goal has been greatly overstated, says an Iowa State University psychologist.
Marcus Credé, an assistant professor who studies techniques to improve academic performance, and his colleagues conducted a meta-analysis of all prior research on grit. Their results, to be published in a forthcoming issue of the Journal of Personality and Social Psychology, found no evidence that grit is a good predictor of success. While some educators are working to enhance grit in students, Credé says there's no indication that it's possible to boost levels. And even if it was possible, it might not matter.
