The noice isn’t about the effect, it’s about trying to scale the outcome. We essentially have proof of a method that is significantly better than what is used with the broad population, but we cannot scale it to the broad population. That’s the “problem” in the two sigma problem.

And in general ongoing from “it’s obvious to me” to a quantized effect is always an effort. For instance I don’t believe you are correct in assuming that one would see a two sigma effect in physical exercise when comparing someone who attends a regular exercise course va someone who spends the same time with a personal trainer. Two sigma is a lot, and you won’t be lifting significantly heavier weights from hav a PT vs doing starting strength training. In my opinion you would most definitely see a two sigma effect from doing steroids though. But this is all pure speculation which underlines that part of the “noice” is about the documented aspect of the two sigma problem, where we have a body of data to work against not just personal assumptions. That said if anyone has studies on personal trainers va course work in fitness I’d love to see my world image challenged by data.
