> If you’re regularly having arguments with well-informed people of goodwill, you will probably ‘lose’ half of them–changing your mind based on what you’ve learned. If you’re not changing your mind, it’s likely you’re not actually having an argument (or you’re hanging out with the wrong people.) While it can be fun to change someone else’s position, it’s also a gift to learn enough to change ours.

What kind of arguments are these? Are these "this episode of TV was not good" or "the earth is flat" or "I think rent is too high"? This statistic seems a) made-up, and b) as simplistic as conflating all "arguments" into one group of indistinguishable arguments.
