    We can’t prove that the world we live in wasn’t created last Thursday, with our memories, the growth rings in trees, and so on created by a (near) omnipotent trickster to deceive us. But science and rationality give us tools for determining what’s worth taking seriously, and sorting out the reasonable, but unconfirmed, claims from the unverifiable hogwash.


  • Knowledge is what happens when you’ve evaluated enough evidence to reject the null hypothesis that something is false. If you haven’t seen the evidence, but still think it’s true or false (you don’t lack belief), then you have a belief about it. As such, knowledge is a type of belief with extra justification.

    If I’ve reviewed enough evidence I’m comfortable saying I can reject the null hypothesis, that is I have a belief that it’s knowledge, I’ll call it as such. If I haven’t, I’ll couch my confidence in my belief accordingly.




  • When a contract ending almost caused Sony to remove all Discovery content from users last year, including digital copies of things people had paid full price for, the cracks between buying a digital license and actually owning something that can’t be taken away became more visible to a chunk of people. It’s something, but it’s not ownership, and it can be taken away based on agreements you may have no way of gaining insight into.
