🐀 A useful explanation of “postrat” vs “metarat.” @FluidityAudio just pointed me to it; I missed it when @nosilverv wrote it two years ago.

In short: rejecting the rat vibe (= post) vs rejecting the substance (= meta). rivalvoices.substack.com/p/fuck-it-we-b…
@FluidityAudio @nosilverv A persistent confusion I keep trying to dispel: “postrat” generally contrasts specifically with LW rationalism; “meta-rationalism” contrasts with the whole 2500+ year history of rationalism, but especially its still-influential mid-20th-century high point. meaningness.com/collapse-of-ra…
@FluidityAudio @nosilverv I also wasted a lot of effort trying to find some specific content in LW rationalism. I have a professional interest in different rationalist theories (going back 40+ years now). It took me years to figure out that there’s nothing at the center; it’s all vibe and no substance.
@FluidityAudio @nosilverv I also have a quasi-professional interest in subcultures, and LW is quite interesting as a rationality LARP. In the 90s, it would have been called rationalpunk (because -punk meant “subculture”).

It’s better as a subculture than as a subsociety—but that was true of all of them.
@FluidityAudio @nosilverv In other words, enjoy the playful cultural products, but think twice before joining the social scene.

This is what I mean when I say “meta-rational expertise.”
Three categories of faculty-level intellectuals, extending this sports analogy.

1️⃣ Nearly everyone is running toward the scrum where the ball is. By the time they get there, it will be somewhere else. This is a total waste, but you can make a decent career of it.
2️⃣ There’s a half dozen big-swinging-dick types in the scrum fighting to move the ball a few feet forward. They have the connections and funding to stay in the scrum and get most of the glory.

I find this tiresome and unattractive, but it’s how we get incremental progress.

.@slatestarcodex’s meta-rationality, 🧵 Part The Second:

Everything Wrong In The World Is Caused By Failing To Do Meta-Rationality Competently

@slatestarcodex The @slatestarcodex micro-grants program excites me because—at a guess—great things will come out of it, but most awardees would not have survived accountable, BUREAUCRATICALLY RATIONAL evaluation:
@slatestarcodex 👨‍💼 When you can’t be rational in a way that meaningfully optimizes what actually matters, but you are accountable for being rational anyway,

you naturally fall back on using a mindless procedural checklist. That lets you avoid blame and makes your work look smooth and competent.

🧵 Case study in meta-rationality: @slatestarcodex’s fascinating reflections on running a micro-grants program.

Naturally, he wanted to be rational, and found you can’t do this that way, so he got meta-rational (as one should when rationality fails).

astralcodexten.substack.com/p/so-you-want-…
@slatestarcodex “Rationally” would be calculating the probabilistically expected utility of each grant project, and funding proposals accordingly.

You can’t do that because you can’t meaningfully estimate probabilities…
@slatestarcodex … and utility isn’t actually a thing, so you can’t compare dissimilar sorts of projects …

.@lumenphosphor was telling a wild story over dinner about friends of hers who put on a play based on a wild story about someone nearly burning down a house

and partway through I started nodding and saying Yah, yah,

when she got to the explosion, I pulled down my shirt
@lumenphosphor “I still have the scars on my chest,” I said

and gradually it dawned on her that she was telling me the a story about a play based on a diary entry about me

FRAME COLLAPSE: when you realize that the world in the story is THIS world and it is sitting across the table from you
@lumenphosphor Now you are reading a story I am telling you about @lumenphosphor telling me a story about a play about a diary entry about me….

Tfw you learn one of your most spectacularly stupid moves got made into a play thirty years later—and a performance is on YouTube.
The play is a dramatic rendering of an entry someone found in a diary, then thirty years old. Apparently the performers assumed, based on mentions of consumption of copious quantities of counterfactual substances, that it was largely or entirely hallucinatory.
The diary entry is, in fact, entirely accurate. I am "Dave" in the account.

I myself had not consumed any counterfactual substances. I can be spectacularly stupid without needing chemical help.

🧠 Why is there so much nonsense neuroblather mixed into current writing about therapy, self-help, and meditation?

Think I might have just figured this out… 🧵
The supposed neuroscience invoked in explanations of meditation, emotional regulation, etc. is almost always false. But that doesn’t even matter!

If we knew the hippocampus or amygdala or whatever caused depression, it would have zero implications for self-help, meditation, etc.
Mind/body dualism is the natural human understanding. OBVIOUSLY your mind is an entirely different sort of thing, separate from the material world, independent of it except for being accidentally trapped in a body.

This is false but we automatically fall into thinking this way…
