I've noticed that my System 1 automatically discounts arguments made for points that benefit the speaker even more when the speaker sounds either prideful, or like they're trying to grab status that isn't due to them, than when the speaker sounds humble.

I've also noticed that my System 1 has stopped liking the idea of donating to certain areas of EA quite as much after people who exclusively champion those causes have somehow been abrasive during a conversation I've listened to.
