Remembering a tense exchange with a DARPA program manager at a AI workshop on automated planning. I said that in the fog of war, planning doesn’t work, so you have to improvise. He was Quite Irate. Drew McDermott calmed him down for me (thank you Drew)! ig.ft.com/russias-war-in…
I was 25 at the time. I’ve gotten somewhat better at diplomatic speech since then. Not a temperamental strong point, though.
“First, make a plan. Then execute it.”
—Rationalism

“Russia kept adding units to the huge convoy stuck outside Kyiv despite the fact it had not moved for days, stopped by a likely combination of fuel shortages, vehicle breakdowns, Ukrainian attacks and obstacles ahead.”
—War
Trying to fight a modern war in postmodernity. #FAIL
When modern methods fail, there’s always the Medieval ones to fall back on.

Anyway, this is a great summary (via @robertwiblin):

🧬 Science reform should be evidence-based. We need WAY more qualitative evidence to better understand what makes scientists productive or not.

There are only a handful of people doing science ethnography. Can we get more researchers onto this task? nintil.com/science-fundin… Image
To do science ethnography well, you need to understand both the scientific field AND ethnographic theory and methods at the Master’s level at least, and ideally PhD-level in both.

Currently this is nearly career suicide. Must change if we want to understand how science works.
A success story is Park Doing’s ethnography of the Cornell synchrotron. After doing an electrical engineering Master’s, he managed the synchrotron X-ray source while doing an ethnography PhD. Image

🐀 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.

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….
