An abridged introduction to LessWrong

There's a lot of material on LessWrong... just glance over the list of sequences, top scoring posts, or recently promoted posts, and probably a lot of topics will catch your eye. For people who already have a science-y background who want a shorter introduction to the readership's "code base", here is my personal choice and ordering of material to read or glance at:

My rationalist imperative
- "I especially want to attract people in academia and positions of intellectual leadership to being actively and morally rational, since their attitudes spread to their students and apprentices. When you have an intelligent mentor who isn't using her intelligence to directly analyze and improve her own life, you're unconsciously less convinced it's a fruitful pursuit. When the opposite happens, it can really start a cascade.
- Provided such a cascade preserves peoples' sense of morality, which requires some serious care to ensure, it can be a great thing for them and the people around them."
I don't do sarcasm
On the internet, I am never being sarcastic. If you're already worried you're being tricked with meta-sarcasm, then you understand my complaint: there's simply too much sarcasm online.
So I'm inviting you to relax. Please, accept that I'm at least a half-decent person, who's publicly pre-committing to sincerity because
- I value being understood, and
- I don't take pride in deceiving others.
In particular, I consider optimism a valuable commodity when it's justified, so I never portray it sarcastically. If I say "Good for you", it's because I actually mean it.
