Really illuminating paper here! I appreciate you sharing this. Here's what I think - innate ability is overvalued, everyone! If you hone your skills over time you will seem smarter than you are & you lose some of your shyness & inhibitions w.r.t. asserting yourself & expressing your opinion. My top grades were a 2200 on my SAT's, 31 on my ACT's, & I was an honors student in college. That being said, I don't think that correlates with intelligence. That just correlates with testing well. Isaac Newton made major contributions to his STEM career in science, and he DID have a lot of innate ability but he also worked at it, which I like. I don't feel that Warren Buffet has a lot of ability, yet he uses the math skills he has to sell stocks profitably. The common character trait of these two examples is that they work at their skills - no one gets a free ride.

Productivity matters more than ability. When I first sold the product Keysaver (1) I was embarrassed about becoming a 'career-driven adult' & being less academic, but I had to learn how to make a face & make that transition into adulthood & out of the school lifestyle. Nobody is outside of this paradigm.

I'll make this analogy:

When you're single, you might think you're great looking but if no one likes you there's no PROOF of that. When you have a thing with someone sexy, that's validation that you yourself are reasonably attractive & normal enough.

Innate ability or talent is great but there's no PROOF that it's great. When I try to prove that ability, that's validation that I'm reasonably smart & intelligent enough to work for a living.
