To get it in, the Edwards Brain Damage article describes my journey in thinking very clearly. It clearly points out where I was having difficulty with the concepts, to how I started to accept, and now, when I read that article, I see it explaining something I very much experienced, and have friends who have experienced it as well. Personally, not talking about others.
Expanding it, though, I see my same issues in others all the time -- the same arguments made, the same stated difficulties and disbeliefs. It's absolutely a thing, this cognitive bias that permeates the hobby, mostly with long term players. I don't think less of them at all, because I was one, and remember being there, and remember the difficulty. It's similar to being an ex-smoker, which I also am. I remember both what I enjoyed about smoking and the difficulty in quitting, but I don't think poorly of people that haven't made the same choice. Some ex-smokers do, though, and I regret that Edwards seems to be in the latter category and how it bleeds into his writing. However, that doesn't mean that what he's saying is incorrect, but it's easy as a smoker to dismiss the words of an ex-smoker who uses salty language like "nasty smelling." I recall that, as well.
The concept discussed in that article is a real thing. I'm personal proof. The difference in how I would approach that article and how Edwards did is that I don't think I'm a better person for addressing my cognitive biases. I've made my choices, and I like them. You're welcome to yours. I'll gladly extend a hand and help if you're interested in looking at different ideas, though. I find Edwards to be too dismissive in general. That he wrote those pieces in a particular zeitgeist and they're being examined outside of that zeitgeist amplifies that, but it doesn't create it. I'll argue against the amplification, but I'll agree that Edwards could be a nicer person. That's not sufficient to dismiss his writings, though. I'd prefer if people could look at the ideas, but I also recall being an ex-smoker, and you don't want to talk about quitting until you want to talk about quitting, so I get it. What I don't get is showing up in threads where quitting is being discussed (to continue the analogy) only to derail or attack the concept. Or even to claim that vaping is the same thing as quitting.
