I think a lot of people need to be educated about what the benefits of debate are and how they manifest slowly over time.
Care to give any examples and the reasons for your first position and subsequent change?
I also liked to think analytically and enjoyed the intellectual stimulation I got from certain online forums (this one included). I liked how people would trade counterarguments and keep each other honest by pointing out bad thinking or logical fallacies. When someone would argue against something I believed in, I would argue back. From their perspective, my mind was not being changed and they were wasting their time, but from my perspective, the things they would call me out on stuck with me. I tried to avoid falling into logical fallacies and bad arguments because I knew I'd be called out on them. This restricted the ways I had to justify my beliefs, so that made it challenging. Then at church I noticed that nobody was being held to these standards at all, and fallacious reasoning was being let fly freely and constantly. I experienced a lot of cognitive dissonance during that point in my life which ultimately led to deeper investigation and study. I give a lot of credit to honest online debaters who pushed back on my ideas and kept me honest about the substance of my arguments.
