One of the most popular pop psychology concepts to take hold in recent years is that of the “growth mindset.” The belief that you can improve your mental powers (grow your brain) can be a powerful tool in helping you actually achieve the success you desire. The converse mindset, or “fixed,” keeps you tied so heavily to the idea that you need to perform well that you fear doing anything that could jeopardize a favorable outcome. But what if your mindset doesn’t really matter? What if the idea is just an oversimplification, as so many pop psychology concepts are? Alexander Burgoyne, postdoctoral researcher in the School of Psychology, co-authored research on 63 studies of growth mindsets showing that there was "no support for meaningful changes in motivation and behavior." Also, many of the studies showed inadequate study design, reporting flaws, and bias.
