This is a thread of things I've recently published, starting with my book from last year, with Open Book Publishers, defending the claim that knowledge is interest-relative.

I'll continue this thread when new stuff comes out.

Knowledge: A Human Interest Story
In this book the author argues for a groundbreaking perspective that knowledge is inherently interest-relative. This means that what one knows is influenced not just by belief, evidence, and truth, bu...

I think it's even more Nordic-coded. Everyone I've met from Norway and Finland was like "Of course it's important to be able toski long distances and then shoot. That's why we're not speaking Russian here."

I thought that most of those had a steady source of income, either from fixed costs for users or from ads, and the microtransactions were a nice bonus. But I could be wrong - maybe there are some that live on selling swords or power-ups.

I think the analogy to music would be bundling across local newspapers. Roughly no one pays for a subscription to local papers outside where they live. But would people pay for a bundle that includes local coverage of every town in the country? Maybe.

I’ve never seen anyone make microtransactions work as a primary revenue stream over any time.

The music case is instructive. As soon as it became possible, people ditched iTunes for streaming. For a few years we replaced albums with songs, then replaced both with whole catalogs.

The whole era either side of the Atlantic would have been a golden age. Marat was literally a poster, de Miranda would never have shut up, Dessalines would have been memorably blocked by the mods on every site except the one he owned, etc.

There is some philosophy of science stuff about this. The part I know the best is fairly abstract modelling like this paper, but I think there is also some more historical work on what kinds of diversity are needed for a scientific community to work well.

my students and I are trying to figure out the meaning of "slash," as in "I'm an actor slash writer", contrast "and" "or" and "and-or"

we've worked that, in a context in which A & B are holding their office hours together:
I'm going to A { and / *or / slash / *and-or } B's office hours

Right, but I thought the earlier post about sophistry was suggesting the other direction, and that seemed pretty implausible to me.

I'm not sure there's anything wrong here, but if there is, I suspect the causal arrow goes the other way: Anthropic pays her (in part) because she already believes these things.

A lot of pro-industry science over the years comes from people being paid to do what they wanted to do anyway.

In Australia, you'd only see someone described on a chryon as an "OK Senator" if it was a satirical show, and the Senator was completely useless.

One of our grad students, Mica Rapstine, has written about how properly valuing something requires being angry when it is mistreated.

Not quite the thing you’re looking for I suspect, because not about utility, but might be adjacent to it.

Minneapolis is a place that means a lot to me, so I wrote a short Substack about the city, its people, and what we all owe them.

Glad to share a new paper with Ivan Boldyrev and Bob Sugden, written for the 75th anniversary of the famous 1952 Paris conference on risk.

We reconstruct the rich discussions at the meeting and address the “sleeping beauty puzzle” linked to ideas presented there by Allais and Arrow.

Lots of Dems want to find their version of early 90s Paul Keating, who did all these things perfectly, and won the longest of long shot elections.

Then they have to hope their candidate doesn’t turn into mid 90s Paul Keating who stepped on every rake he could see.
Gallego’s whole thing of moderating on policy, radicalizing on tactics/partisanship, and attacking when events allow is pretty clearly trying to find a way through the “popularism/populism/future of Dems” stuff.
