Hey, everyone! I want to share with you a project I've been working on for a while - http://rationalfiction.io.

I want it to become the perfect place to publish, discover, and discuss rational fiction.

We already have a lot of awesome stories, and I invite you to join and post more! =)

Hey, everyone! So I've been reading an article about the expected utility, apparently to figure out whether the risk is worth taking you multiply expected value of the outcome by it's probability.

And apparently insurance companies can make money because the expected utility of buying insurance is lower than it's price.

So why would  buying insurance be the rational action? I mean intuitively it makes sense(you want to avoid the risk), but it doesn't seem to fit well with this idea. If insurance is almost by definition is worth slightly less than it's price, how is it worth buying?

(sorry if it's a dumb question) 

How do you think curriculum of rationality 101 should look like? I want to make a brief course(a series of short animated youtube videos), ideally on the level accessible to a normal 14-17 year old person. Can you help me to make the list of concepts I should start with?
