Here's a simple idea: You can't reason someone out of a position they didn't reason themselves into.
And three interpretations to consider:
0: The default: That person is irrationally attached to being wrong. Best to walk away, argumentation will be futile, and I have a life to lead.
1: Whoa! Sometimes that person is me.
2: If they didn't reason themselves into it, how did they get into it? What if their position represents their values, not some perfectly architected strategy for maximizing some hypothetical measure of rightness? In that case, if I wish to discuss it with them, I should be talking about their values and my values and where they intersect, rather than arguing right and wrong?
I have personally found all three of the above useful at one point or anther.
> What if their position represents their values
One of my best professors often asked me:
"what are you trying to achieve here?"
Every time they asked this, it always put me into a deep thinking mode. In some cases it did trigger defensive mindsets, but I think having to actually engage by taking a step back and think deeply is for the best if you want to have any hope of changing your mind on something.
> You can't reason someone out of a position they didn't reason themselves into.
this is a pithy think to say but its really not true, and every person that has lost their religion and been convinced by rational argument is a counter example.
> 0: The default: That person is irrationally attached to being wrong. Best to walk away, argumentation will be futile, and I have a life to lead.
Disagree here, because:
* Most of us have an irrational attachment to many of our positions. Arguing may or may not be futile, but if you can't "walk away" from most people (except if you sit at home and do nothing, and maybe not even then).
* These people may well be your coworkers on your project or at the organization you work for. So there is no "walk away", you're working with them and will continue working with them.
I don't really like that quote, what is a position but an opinion and how do you reason about options? It doesn't really make sense. Its like when liberals say "reality has a liberal bias", its not a very useful thing to say either because it doesn't work that way in practice. Why do you support abortion? Why do you oppose abortion? People will give perfectly reasonable answers to either question.
My style of online participation has been shaped by 2 ideas:
1. I rarely fully understand my own positions on minutia 2. Writing is rewriting.
I write forum posts to solidify my understanding of my own interests, beliefs, and reasoning. I often edit them multiple times before moving on and ignoring the responses thereafter. I can reference them and have to other people who ask my opinion. Sometimes I do respond back to replies immediately, and sometimes I revisit days later, after I've had time to put it in my day-to-day context. It's not a hard and fast rule.
Posting stopped being about convincing someone else maybe 20 years ago (around age 30). I do post to look back and understand myself. To others, I'm sure this sounds like existential navel-gazing and self-centered blathering, but I don't mind.
