It is interesting that both you (magfrump) and I seem to both be committing Typical Mind fallacies
This is kind of the point of the whole thread :P
And while I, personally, am annoyed by lack of closure, there have been numerous practical reasons not to explain oneself which are both understandable to me and quite rational. Though if you know the person will take your response in good faith, I would (acausally via symmetry with similar agents) appreciate that.
The other day, someone did something I didn't expect. It was something many people have done before; something that I thought of as very normal, but that I in no way understood and had not predicted.
As I said, this had happened many time before, so I wrote it off as "me not understanding people" or "people are weird" for a second, like I usually do, before realizing that "bad at" really means "lacking basic knowledge", which I had never realized before.
And then I thought "I should ask someone who is different from me why people do that, and eventually someone will have an answer."
But many people will have many more questions like this. So, what have you observed people doing time and time again, but never understood? Or something that you only understood after a long time or asking someone about it?
And can Less Wrong tell us, not necessarily why (I for one can make up evolutionary psychology fairy tales all day if I want) but what conscious thought process occurs behind these events?
