One issue is that on a forum, I’m not just writing it for the person I’m replying to: I’m writing for other readers too, including possible future readers. So sometimes I’m trying to be helpful to the person I’m replying to, but other times what I say is more for the benefit of other people.
But even when I am saying something that I think might be helpful to the person I am talking to, my advice, suggestions, corrections, etc aren’t very personalized. I don’t know the person I am talking to well. I don’t know the context of their lives, what other problems they have, what the best thing for them to be focussing on right now is. So I can say general things that I think are true, or true for most people, or something like that. But I can’t give them advice based on their actual context & situation because I don’t know their situation.
And, also, if I take into account what I do know about the person, from previous interactions with them, reading previous threads (including older stuff on the FI list), etc, my experience is that a lot of the long-term posters here have previously claimed to not have any major, ongoing problems or disasters in their lives. Elliot has previously tried to get people to write more about their actual real life problems, and people have refused to do that, many of them claiming that they just don’t have any to write about.
So, if I take that seriously, then pointing out things like logical errors in their writing actually does seem like a helpful & relevant thing to do. In order to improve your ideas or your life, you need to actually find mistakes, errors, etc to change. Since people either don’t have any major ongoing problems or they are unable to see their major ongoing problems, then providing them with evidence of some kind of problem would be helpful – it would be giving them a place where they could start making improvement.
And, also, even if they do have major, ongoing problems, sometimes those things are much harder to work on. They are painful & emotional, or hard to figure out how to change without making major, difficult life changes. It can be hard to figure out how to fix a life that you feel stuck in. And it can be hard to question and change beliefs that are really important to you.
So, in those cases, working on improving your thinking on anything at all might be a helpful way to start improving your life. If you get some practice correcting things like impersonal logical mistakes you are making about ideas that aren’t central to your everyday life, that can help to improve your overall thinking. And it can give you some practice with finding and correcting errors. And if you do that enough, you can start to use those skills to find other kinds or errors too – the kinds that are actually causing you ongoing problems in your everyday life.
