I recently discovered the Less Wrong online community.
To quote their front-page:
Less Wrong users aim to develop accurate predictive models of the world, and change their mind when they find evidence disconfirming those models, instead of being able to explain anything.
That’s a noble goal for an online community.
I’ve only been lurking so far, but chances are that I will stick around.
There are a lot of interesting articles and discussions going on over there, so I highly recommend checking it out for yourself.
