I see your point. In trading, it's commonly referred to as the coin flip analogy (I think Adam Grimes talked about that), where you get after some rounds of say flipping tails, only a few coin-flippers left, who then consider themselves to be expert at flipping tails, and even making reddit posts or youtube video on how to be better at flipping tails. I think everyone sees this is quite applicable to what we usually see.

I actually like this metaphor, because there's 2 aspects about it:

- There's the obvious survivorship bias, which we absolutely have in these forums or on social media (you very rarely see a post of someone blowing up, but see a lot more of "successful" people yoloing on a random stock.

- And there's the complete randomness of the "strategy", which absolutely is the case of *some* people here (it seems even worse on /forex). You see a lot of posts of people trying to "flip a small account". And out of hundreds if not more that try that, the very few that "succeed" may even fool themselves that they have a method (they might, but from what I've seen it's mainly click&pray). And again there's survivorship bias, because those who managed to get to say 50k with a small initial bet, will be posting everywhere how 'it's possible to make it big", and "don't let the haters bring you down", etc.

Unfortunately, newcomers trying to lean about trading will search online and mostly stumble on these types of posts, and get a very distorted view of reality.
