Africa is a continent. "African proverb" makes around as much sense as calling all proverbs of Native American tribes, modern American proverbs, proverbs from Western European philosophy currently used in the US, and their Latin American counterparts, "American proverbs".

"Fred should really cut back on drinking; he just started seeing someone too; like that's going to last... wait, I don't actually have any reason to think that it wouldn't..."

Do you need an articulated reason? If your subconscious ran the numbers and reported the result without showing you its reasoning, that doesn't mean you should ignore it entirely. Perhaps when you notice predictions like that, you should write them down and see how they do?

More crucially, how many trends almost, but not quite look precisely exponential? Are precisely-exponential trends the tip of a long tail, or an additional local mode?

If the book turns out to be good, it could be a good way to "spread the word," seeing as there doesn't seem to be a lot of Bayesian literature for the layman out there

Oh, i'm immediately reminded of the horrific scientific explanation in the movie 2012 that was something like, "The neutrinos are turning on us." Whatever that means.

I think people also invoke science in debates without the accompanying critical thinking skills that are supposed to go along with science, as if it's just a weapon and the more scientific "facts" you know, the better chance you'll have in winning the argument.

"If a man is offered a fact which goes against his instincts, he will scrutinize it closely, and unless the evidence is overwhelming, he will refuse to believe it. If, on the other hand, he is offered something which affords a reason for acting in accordance to his instincts, he will accept it even on the slightest evidence. The origin of myths is explained in this way." --Bertrand Russell

Umm...I don't know how rigorous this explanation this is, but it might lead you in the right direction...because if you consider the Venn Diagram with probability spaces A and B, the probability space of A within B is given by the overlap of the two circles, or P(A∩B). Then you get the probability of landing in that space out of all the space in B...as in, the probability that if you choose circle B, you land in the overlap between A and B.

That's probably not what you were looking for, but hope it helps.

Ayn Rand's philosophy is actually "Objectivism," not "Rationalism."

I actually disagree; the "Rationality" tagline is highly appropriate, especially as the singularitarians here are devoted to rational thought processes anyway in AI research.

I would, however, like to point out that the site seems to get mixed up with other groups as well:

"RationalWiki" - the highly politically partisan pro-science web page (kind of an opponent to LW, apparently.

Rationalism (philosophy) - Spinoza, Leibniz, Descartes (but they pretty much ignored empiricism so they have little to do with LW thinking)

Rationalism (Ayn Rand) - the worst kind. LW isn't a social-engineering organization, especially one committed to absolute "rational" selfishness.

So the tagline is good, but we should try not to get mixed up with those groups.
