A fair question! Put briefly, I would say that studying the humanities would make one more aware of/able to comprehend situations involving others and their motivations (which is... most of them), with the example I gave being one situation that I figured would be more familiar to the crowd here at Hackernews.
> It just seems like another common example of people taking things they consider good and relating them to humanities.
It seems like that because it is like that :) In other words, I DO consider it good to have a broader view of situations that otherwise might be considered narrowly "technical" because I believe that understanding the human element as part of the situation helps me understand the situation (whatever it may be) way better. I relate it to "the humanities" because it IS related to the humanities.
