Small-Scale Question Sunday for June 7, 2026

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

What employees have you fired so far?

In Zvi's recent post, I noticed an interesting pairing of two things:

Sell your house. Stuart Thompson lets Gemini (because he had a free account there from work that saved him $8 a month?!) walk him through everything involved in the sale, including being his agent. The problem is, Stuart does not seem to realize he does not know the counterfactual?

Stuart A. Thompson: In the end, using A.I. netted me more than $90,000. That includes the premium over the asking price, plus the roughly $36,000 in fees I didn’t pay.

I mean, yes, the agents he talked to early on told him he’d lose money, and instead he turned a profit. But only after the sale did he talk to another agent for an expert opinion, and that expert expected a higher sale price than Stuart got, meaning he almost certainly listed too low. Stuart thinks that after the agent fee he still basically broke even, but I’m guessing he put in more work and stress this way, and took on more downside risk. I know that if I am ever selling or buying, I will be using AI extensively as part of the effort, but I am going to stick with Danielle Wiedemann. I am confident that her help, connections and advice were worth far more than the fee, and would be again.

and:

For those confused about the radiology example, yes, AI is better than radiologists at reading x-rays, and many other components of professional services, and does so at cost epsilon, and this is super useful. Even if no one is out of work quite yet, often there is a ton of value in ‘pretty good answer, vastly better than you could otherwise get without a professional, for cost ~$0’ when the professional costs $1,000 and up.

It was a bit stark, because getting a pretty good answer, vastly better than you could otherwise get without a real estate professional, would seem to cost ~$0, when the professional apparently costs something like $36,000 and up. So why not fire the real estate agent?

There could be a variety of reasons involving the nature of the work, regulatory barriers, etc., but one thing that comes to mind is that Zvi has paid for a real estate agent before and is consciously thinking about what that situation is like when thinking about whether he would hire again. Whereas, I doubt he's hired a radiologist before and is probably not in a situation where he's thinking super seriously about the considerations that would be involved if he had a need for such a service.

This leads me to ask, "Which employees have you fired?" In this case, "employees" can be read broadly, covering folks like real estate agents/radiologists, who you may procure services from on occasion, in addition to actual employment relations if you're a manager/business owner. But I want to particularly hone in on examples where you have paid a human for a particular service in the past and have subsequently encountered a nearly-identical need, but have chosen to not pay a human now for the service.

This question is in significant part simply selfish. I might be missing some aspect in my life where I can save a bunch of money. That would be cool, and I'd like to do that if I can.

radiologist

I recently got a cheap knee MRI at a local facility and wanted to double-check the radiologist's report and maybe learn something about how to read MRIs. So I uploaded the .zip of obscurely formatted images to Claude (highest-powered free model as of a week ago, on high setting) and asked for an opinion. It did a great job of parsing the file and coming up with a plausible-sounding stream of orthopedic gobbledegook, but failed to identify a partially torn quadriceps tendon, which was far and away the most significant finding in the radiologist's report and is generally consistent with symptoms and history. When I nudged it a little bit, it seemed to pick up on the quad tendon, but when I asked it to highlight the finding on the relevant frame it identified a random location on the IT band as the quad tendon. I wasn't quite sure myself at first, not having a ton of experience with either AI or reading MRIs, and I got Claude fairly confused by asking about the difference between sagittal and coronal before I figured out what was going on. (All this took several days, since I was hitting my token cap fairly quickly on high setting.). Super impressive natural language processing, but I'm not sold on its radiological abilities, and I seem to recall hearing quite a while ago that the days of human radiologists were numbered.

Yeah I am sure that AI will come for Radiologists and everyone else eventually but we are still far away. They aren't right all the time, and the expectation is you are right all the time for one (and when they are wrong they are sometimes wrong in the most basic of ways).

That says nothing about being about to talk to primary teams about the read, rare findings, and how to manage incidental findings, as well as other basic radiology tasks.

People want this fight to be over because they hate doctors or certain kinds of expense, but we aren't there yet.

I wonder how its radiological abilities compare to ultrasonic nondestructive testing analysis? Seems like a similar field, and I believe it was getting touted for the latter as well.

It looked like much of the skill of ultrasound specialists was in moving the device around to get the correct locations in real time, and then they would mark it off on their checklist, and a doctor would look at it later (but also they already have an opinion on morality in the moment). So an LLM could replace the analysis, but not the moving the device around while jostling the item being scanned (at least for pregnancies).

Yeah, I was thinking much more of the interpretation that the initial reading-taking.

What is this place?

This website is a place for people who want to move past shady thinking and test their ideas in a court of people who don't all share the same biases. Our goal is to optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.

The weekly Culture War threads host the most controversial topics and are the most visible aspect of The Motte. However, many other topics are appropriate here. We encourage people to post anything related to science, politics, or philosophy; if in doubt, post!

Check out The Vault for an archive of old quality posts. You are encouraged to crosspost these elsewhere.


Why are you called The Motte?

A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, it's an element in a rhetorical move called a "Motte-and-Bailey", originally identified by philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial but high value claim to a defensible but less exciting one upon any resistance to the former. He likens this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired propositions to which one retreats when hard pressed."

On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.


New post guidelines

If you're posting something that isn't related to the culture war, we encourage you to post a thread for it. A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a submission statement. A submission statement is required for non-text sources (videos, podcasts, images).

Culture war posts go in the culture war thread; all links must either include a submission statement or significant commentary. Bare links without those will be removed.

If in doubt, please post it!
