Things got even more interesting when Dweck brought people into Columbia’s brain-wave lab to study how their brains behaved as they answered difficult questions and received feedback. What she found was that those with a fixed mindset were only interested in hearing feedback that reflected directly on their present ability, but tuned out information that could help them learn and improve. They even showed no interest in hearing the right answer when they had gotten a question wrong, because they had already filed it away in the failure category. Those with a growth mindset, on the other hand, were keenly attentive to information that could help them expand their existing knowledge and skill, regardless of whether they’d gotten the question right or wrong — in other words, their priority was learning, not the binary trap of success and failure.
