Well there are general studies and cases to support this -- example: Blackwell, L. S., Trzesniewski, K. H., & Dweck, C. S. (2007). Implicit theories of intelligence predict achievement across an adolescent transition: A longitudinal study and an intervention.

Though I anticipate this is not really what you are drawing at here.

While I can definitely agree that inherent talents or traits may put an individual ahead of others. I just dont see the scenario where talent beats hard work. Now dont get me wrong Im not trying to imply that a turtle can train to outrun a cheetah, but rather that in the realm of intellectual pursuit, I believe the landscape is significantly more malleable. To me, asserting that talent or intelligence is fixed would imply that knowledge and understanding are also static. Yet our capacity to think, interpret, understand and extrapolate is ever evolving. So I still feel the growth mindset is more closer to the "truth" in the sense that novel thinking and innovation can expand intelligence. Im not looking to deny the existence of innate capabilities but rather draw some emphasis to the potential of persistence and effort in learning.
