Researchers found that students perform better in science where they read stories about how famous scientists struggled [npr.org] rather than when they read stories about what those scientists achieved.
The researcher tested how kids reacted to prospects of careers in science and math. When the kids were told how brilliant, what geniuses Einstein and other famous scientists and mathematicians were, their propensity to consider careers in STEM (Science Technology Engineering Math) went down. When they were told stories about how those same people struggled, their propensity to consider careers in STEM went up.
