Good luck on your presentation.
It seems like a better idea to introduce the ideas of rationality and then to introduce LessWrong afterward. I also notice that LessWrong is mentioned as an afterthought in some presentations that I've seen, and that also seems suboptimal. So, I like the idea of LessWrong getting its due in a presentation but I also think that the thrust of the presentation should be about rationality itself.
Also, if you're talking about the Twelve Virtues of Rationality, I've seen people say that they're difficult to understand for people who haven't been introduced to many other LessWrong ideas, and that sometimes they seem cultish. Probably best to stick to the psychology.
But I like your 'concrete goals'.
In a couple of weeks I'll be giving a small (~50m) presentation about LW community on "social sciences sunday" in Saint Petersburg.
Target audience - students, teachers and young recearcher mostly from social sciences and humanities.
I'm planning to at least mention in passing:
1) rationality: epistemological and practical division
2) virtues of rationality
3) big part of learning is by osmosis
4) about sequences => some ideas I found engaging (but those that are at the same time would be easier to explain in 10 minutes)- definetely about inferential distances and looking wise
maybe mention Milgrams experiments or anecdote about Pain and Gain motivation
5) study hall (I tried it just for a bit), meetups, related projects - CFAR (anything else?), International Insights, slatestarcodex?
There is also this:
I am going to spend some more time prepairing and would probably have some good ideas, but I would be really great to have opinions from others. Am I missing something? Or if anyone had relevant experience?
