One relevant thing here is baseline P(beats market) on given [rat / smart] & [tries to beat market]. In my own anecdotal dataset of about 15 people the probability here is about 100%, and the amount of wealth among these people is also really high. Obvious selection effects or whatever are obvious. But EMH is just a heuristic and you probably have access to stronger evidence.
I actually feel calmer after reading this, thanks. It’s nice to be frank.
For all the handwringing in comments about whether somebody might find this post demotivating, I wonder if there are any such people. It seems to me like reframing a task from something that is not in your control (saving the world) to something that is (dying with personal dignity) is the exact kind of reframing that people find much more motivating.
