more on writing immediate thoughts:
if you catch yourself thinking something tribalist (or a mistake in general that you corrected yourself), you might want to post that you had that initial reaction. Also explain how and why you changed your mind. when you’re talking IRL you might accidentally say some tribalist stuff. it could be beneficial to reveal that in writing because the readers might discover some deeper issue you didn’t actually catch.
it could also help to give your readers a more accurate mental model of you. this matters more when it’s a forum where you’re engaging on a long time frame and a large part of the engagement is about you improving yourself. it would also depend on how invested the people on the forum are about you. how much do they actually mentally model you? how much of it will be helpful in order to help you learn more? if they aren’t currently invested in you that much, then you showing more of your mental process would be a reason for them to invest more in you. it shows your honesty, integrity and willingness to improve, and it’s an example of you improving.
