Agreed.
I think this comes down to questions of free will, I'm of the understanding that we don't have any contra-causal free will, so everything we do is dependent on other factors.
Agreed on your points, but I think that this question is besides the point of this thread. Have you been active in the free will threads?
Whether or not "real" free will exists is besides the point. There is certainly something we "perceive" as free will, and that's what I'm talking about here. The factors I mention are outside of that "perceived" free will's ability to control.
If this is the case, it's because I don't have ready answers. What I feel reasonable in David's position is that the general public has too limited understanding of how our genes actually work (to the point of negatively affecting their decision making) and have a more narrow and rigid understanding of "innate talent" and personality or their ability to develop certain skills than what the science seems to show.
As to your question, I don't know about most people becoming "geniuses", but I agree with Shenk that we don't know until we try our best in excellent environments for years and years. I also agree with him that this is not the point. The point is rather that how much could we improve if we really put in the effort and have (or search out for) a beneficial environment. I also agree that the sacrifices required of becoming "genius" are in many cases not productive to other kinds of things that we value.
Also, many people may not have such things available. What if you were born poor and grew up poor, with limited stuff available?
I hope this was a reasonable answer.
The following points seem very interesting and important for me:
* Studies that show how things like "the will to challenge yourself", persistence, motivation, etc. can be developed with the right kind of guidance and / or mind set, this can be something very subtle as seen in the Carol Dweck study I quoted in the OP. Did you know about this study beforehand?
This is not necessarily a surprise, nor does it have to do with my main point.
* Gene expression, epigenetics and GxE.
Again, timing is the thing. Gene expression and environmental factors that only matter during womb development or early childhood are examples of "out of your hands" factors.
* Abilities like the absolute pitch are available to pretty much all of us in a favourable environment early on.
Early on -- see, there you go, if you miss that childhood window (in which far less factors are "in your control"), then it's toast. Didn't have parents that told you about developing it? Didn't have a teacher about it? Didn't want it
at the time but wanted it later? Tough, you're screwed. In a way I suppoes that last factor does imply a "will" effect to some extent, but there's also a naivete component: you probably don't understand this at that age.
What you
do seem to make a good case for is that society and parents should guarantee everyone the ability to have an optimal environment for the free development of their potentials. Missing out on such stuff because of poverty and ignorance indicates a sorely broken and twisted society.
The whole idea here is that "success" is a
combination of factors coming together, some of which must be supplied by the person's own will-power, and some of which cannot be so supplied. Nothing is simple and nothing is black and white.
And almost every famous "world class"
anything usually evidences their talent early on. Granted, they must work hard to actually
use it to its full potential, but if it ain't there in the first place... It's a combination, it's not one-or-the-other. E.g. Michael Phelps showed phenomenal swimming ability in single-digit childhood years. If you want to claim it's mostly "hard work", then I suppose you have to say that his mates did not work so hard. Or maybe they didn't, but maybe that's because they weren't getting ahead, they were "maxing out", so to speak. The best motivator, or one of the best, to work more is results. A lack of results can (though doesn't
always) indicate bumping up against an uncontrollable factor of some kind.
