Small-Scale Question Sunday for January 18, 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.

Does anyone have their own equivalent of a personal "antimeme", a concept you familiarize yourself with (potentially with difficulty) and then inevitably forget unless you make an intentional effort to look it up?

In no particular order:

  • I often have to look up whether I need an x86 or x64 executable when I need to download a program
  • ECGs. Fucking ECGs. I get good at understanding them when I absolutely have to (before exams), but guess what, by the time the next one rolls around, it's all out of my head.
  • Fourier transforms (how they actually work, and not the conceptual strokes)
  • And many more, all of which stubbornly refuse to come to mind, because of course they do.

I can do TIA 586B in my sleep (orange-white orange, green-white blue, blue-white green, brown-white brown), and only get TIA 586A right without looking it up 50% of the time. That's not a good combination.

Constantly get df and du commands mixed up. RAID 0 versus 1. Vi keyboard shortcuts.

For historical reasons, a lot of FAA regulations go by the name 'Part XXX'. I can tell you the differences between Part 61 and Part 141 flight schools at length, so long as you don't ask me which is which. Sometimes I'll even throw in Part 151, which isn't even a relevant thing. Likewise, tach time versus hobbs time drives me up the wall, and I have to derive tach->tachometer->turning->engine time every time.

Sin and cos. And I use them a lot.

Okay, funnily enough, while I do have both schemes straight in my head (we had one building that for whatever reason seemed to have constant network issues that we largely solved by going from 586B to 586A, so I got used to the difference pretty quickly as we reworked the wiring) I swear I had 586B as 586A in my head and vice versa until seeing this post and reminding myself that no, we were using A in that clinic and not B. Doh! facepalm

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!
