So people pretend to care about others because this might cause others to actually try to help them? It's a plausible theory of human behavior, but seems awfully complicated to describe the mental processes of people we are all but explicitly told are too stupid to consistently implement their preferences.
In other words, there could actually be a reason that people think caring is the right thing to do, but trivial inconveniences and other errors of thinking prevent them from actually doing what they really think is right. This seems like a better description of most folks' mental processes than "doesn't care, and knows it" - which is the implication I get from the response sentence.
I would say the likeliest explanation is that people do care, but only insofar as it enables them to signal that they care. Caring much farther than that is pretty much pointless, from an evolutionary perspective, and probably actively detrimental.
This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 96. The previous thread is at almost 300 comments.
There is now a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system.
Also: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, .
