I think the most realistic thing here is the luck element. You have people around you passing and making it look easy and saying to do exactly what they did and those people make it all out to be a skill game. But you follow their exact method and still fail. And keep failing. Making you think there's some secret sauce that they aren't telling you about. But in reality the difference was just luck. That in one game y…
Reminds me of the poem The Road Not Taken by Robert Frost. Initially it seems like it's a poem about working hard and taking risks, but it's actually about old people lying to themselves, trying to forget that their success was actually just luck. About half the professors I worked with were responsible adults, and half were narcissistic children who would do exactly what you described, "just do what I did", and when…
You definitely need both, and I think this is what people forget. Work is incredibly important, but you can do a lot of good and hard work and just be unlucky. That honestly is probably one of the more distinguishing differences between students/faculty at top institutions vs mid. Especially since success is a compounding event, thus an early success can catapult someone forward. We shouldn't diminish their hard work by saying it is all luck, but neither should they diminish others hard work and frustration as a lack of working hard enough when luck plays a significant role in the system. Neither is failure strictly due to luck. It is messy and we need to accept that this is the reality of the world, especially if we want to make the system more efficient and more "meritocratic" (quotes because previous comments and their relationship to Goodhart, the difficulties in evaluation and necessity to embrace noise).
Though your last point about the top tier breezing through, I can completely relate. I see a lot of low quality papers from those institutions get high marks and it is very surprising and definitely not consistent with a blind evaluation system... but I think most of us already know that.
