Two great intros to Bayes’ Theorem, from opposite angles: Yudkowsky’s Intuitive Explanation of Bayes’ Theorem and komponisto’s Bayes’ Theorem Illustrated.

How do we know that 1+1=2? A (video) journey into the foundations of math.

You Are Not So Smart: a blog about how we deceive ourselves.

The latest episode of Reasonable Doubts features a great conversation between Jeremy of Reasonable Doubts and two Christian podcasters about free will vs. determinism. Both sides are coming from totally opposite perspectives, and they spend a great deal of time trying to understand each other, so the it may be a helpful dialogue for those trying to work these issues out.

After 1.5 years, there are still *no* ads on this fairly popular site. However, people keep asking me to put up a donation link, so I put one in the sidebar. Go click on it if you want. That’s the last you’ll hear about it from me. :)

Seconded.

I was familiar with Ed’s intro to Bayesianism, but that visual one is awesome. Much more comprehensible for me at any rate.

I didn’t understand the math video. I thought 1+1=2 was basically a definition; not something we discover or prove, but something we agree to. I think the speaker was saying that his opinion is that math is only “true” in that it usefully models our world. Is that to say that it is most useful to have a single exclusive term for 1+1, so that you are not using “1″ to refer to 1+1, nor are you using “2″ and/or “3″?

I disagree with Dennett. Arithmetic is only universally true in the same way that the statement “Homosexuality is wrong” is universally true. That is to say, it’s only true, conditioned on some other hidden premises. In this case, it’s ZFC, or in a simpler case it could be the Peano axioms.

However, these are axioms. Math is definitely not universally true.

The You are Not So Smart blog is fascinating. I was absorbed and stayed up late into the night reading every post. Thanks for that. I’ll keep an eye on it.

A note on the Dunning-Kruger Effect (noted on the excellent

You are not so smartblog); there are substantive criticisms and corrections to the initial research. If you have the time, look at that as well so you don’t misunderstand what the current research has discovered and what the limits are. If you don’t have the time to look at everything, it’s still quite useful to read the initial paper.Hermes(Quote)

Its hard to imagine a world in which basic arithmetic isn’t true.
