The significance of grit in helping us reach success has been greatly overstated, according to a new meta-analysis of existing research on the topic.
In fact, Marcus Credé, an assistant professor at Iowa State University, and colleagues 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 were possible, it might not matter.
Grit is defined as perseverance and commitment to long-term goals. The research—often associated with University of Pennsylvania professor Angela Duckworth who first studied grit—is relatively new compared to the decades of work on performance indicators such as conscientiousness and intelligence.
Credé says his team’s analysis of 88 independent studies representing nearly 67,000 people shows that grit is really no different than conscientiousness. The findings will appear in the Journal of Personality and Social Psychology.
