As in; I wonder how much politeness norms evolved as being a set of the most culturally and morally defensible default actions. They're both practically useful (e.g. you can't be blamed for not caring when you ask how your day was), and also a signal that you know how to defend.

I saw a few minutes of a reality TV show where a celeb was interrogated by ex-SAS. When he responded with rudeness, they told him “that would get you killed”. I think politeness as a defence has always been a thing - it’s probably how it started in the first place. /1
