I think people who are suffering DK effect, tend to stay that way because when variance helps them out, they're too stupid to realize that they got lucky or that they're making -EV plays because it looks like +EV play when they win.
One thing I realized is that majority of poker players think they know how to play poker and think they know what they're doing. They don't question anything about their plays nor analyze. If you go to casinos
, you can find lot of these rebuying degenerates who are too stupid to realize that they are tilted and that they are not playing their game. There are lot online too.
Almost nobody starts out as a long-term profiting player. It's just matter of who's smart enough to realize that they have a leak in their game and fix it, and who's too stupid to realize that they have a leak. Ones that attempt to study and fix their leaks eventually work towards becoming a profiting player while people with DK effect can never become a profiting player because they're too stupid to realize themselves. DK effect basically means stupid people are too stupid to realize that they're stupid.
And like scorpion1367 said, I wish I find more of these at my tables. It's just frustrating when their -EV plays gets rewarded under your expenses. But as I've been to casinos many times lately, last year and this year, I find so many of these people, who are just degenerates chasing after their money because they think they're good enough players who can make their money back and that they just only bcz they were unlucky.
