Beliefs and aliefs

What does it mean to believe?

This is not supposed to be some Deeply Wise prod to make someone write philosophical accounts of the mystical uniqueness of human consciousness or some such. It’s an actual question about the actual meaning of the actual word. Not that words have intrinsic meanings, of course, but what do we mean when we use this word?

And like many good words in the English language, it has a lot of meanings.

LessWrong has a lot of talk about this. Amongst the meanings of the verb “to believe” talked about in the linked Sequence are to anticipate an experience, to anticipate anticipating an experience, to cheer for a team, and to signal group membership. And of course, that’s not all. Some people in the atheist movement, for instance, use the word “belief” sometimes to refer to unjustified or faith-based models-of-the-world.

Now, there is a very interesting other word in philosophy and psychology: “alief.” To alieve something is to have a deep, instinctual, subconscious belief, and the word is used especially when this subconscious feeling is at odds with the conscious mind. The W uses a few examples to explain the concept, like the person who is standing on a transparent balcony and, in spite of believing themself safe, alieves the danger of falling.

This is a very interesting (and fairly obvious, after you grok the difference between your Systems 1 and 2) internal dichotomy. Ideally, we want our beliefs and aliefs to be identical, and whenever we change our beliefs we’d like to likewise change our aliefs. And I think much of what Yudkowsky means when he talks about making beliefs pay rent refers exactly to this concept, turning beliefs into aliefs. This would seem to be very useful for rationality in general – a large part of rationality techniques consists of a bunch of heuristics for turning conscious deliberations into intuitive judgements. And of course, it’s very hard to do.

Pascal’s Wager (the one that says that, on the off-chance that god does in fact exist and will punish you for not believing, you should believe in it) has lots of flaws in it, but I think this is a particularly severe one. Sure, maybe the human brain is absolutely and completely insane in how it translates beliefs into aliefs and vice-versa, but it seems to me that, most of the time, you can’t just, by an effort of will, force it to turn a belief into an alief. And Pascal himself admitted this, and said that what the rational person should do is act and behave as if they believed until they actually did. And I’m sure that would work with some people, eventually, in the sense that they’d believe they believe, they’d profess and cheer and wear their belief.

But I’ll be damned if any amount of praying will actually convince me, on the brink of death, that I’m about to meet the Creator.

Or some such, depending on which religion you’re talking about.

And one would think maybe a just god would reward honesty more than barefaced self-manipulation.

Whichever the case, you can’t just choose to anticipate experiences: either you do, or you don’t, for good or for ill. And the brain isn’t completely stupid, if it didn’t move somewhat according to evidence it would’ve been selected out of the gene pool a long time ago, but it’s not terribly efficient or smart about it, and its belief → alief translation procedure can be overriden by a lot of other modules, or twisted and hacked into unrecognisability. But it seems that, in general, a lot of rationality heuristics boil down to: okay, this is the normatively correct way to think – how do I internalise it?

I don’t know. It appears to take lots of practice or some such, and different kinds of belief require different kinds of alief-generating, and some people seem to be naturally better than others at this “taking ideas seriously” skill. But we all know that the whole of rationality isn’t limited to what Less Wrong has to offer, and as further research is done, well, I’d be eager to learn how to more efficiently internalise my beliefs.
