Choosing the word "overstate" was extremely poor word choice on my part, given my argument. The "statedness" of the success is subjective, regardless.
If we, as a society, did not assign degrees of greatness to accomplishments, there would not really be any. You're free to disagree, but to me, this is an obvious conclusion of human nature and history. Do famous politicians deserve their place in history, given that their accomplishment is the result of thousands to hundreds of millions of people support them? Did Newton deserve his success? By his own word, he was standing on the shoulders of others. However, consider every scientist who followed him desiring to achieve his level of prominence - nearly every human who fervently applies himself to any single pursuit desires that, whether or not they will admit that to themselves or others. If history did not allow the idea of outliers, in favor of the argument that all discoveries were collective achievements or "an eventuality, regardless of who", Newton, and those after, would've had far fewer shoulders to stand on - those minds would've applied themselves elsewhere.
I am not arguing that we, as a society, assign the proper "weight of recognition" to an inventor, discoverer, politician during or after their lifetime - that is a separate question. The chain is regarding "whether or not we should assign large weights of recognition to individuals".
I'll agree to disagree rather than continue writing a thesis - I believe my perspective to be inalienably correct, though.
