In early July, Cassie Pritchard argued on Twitter that liberalism had failed; it bet the farm on economic progress making people happier, but although it delivered impressive economic progress, happiness had failed to follow. In late July, I countered that Pritchard had made a mistake by comparing happiness to income, when the literature instead supports a correlation of happiness with log(income).

[previously in series: 1, 2, 3, 4, 5, 6, 7, 8, 9] Paul Graham once said that every city sends a message. New York says you should make more money. Berkeley says you should live better. Boston says you should be smarter. People shouldn’t decide on a permanent residence until they’ve lived in several cities and understand their differing psychological effects. San Francisco sends a message too.

Superforecasting is the art/science/sport of predicting the future - for example, who will win elections, which countries will fight wars, when key technologies will be discovered. Over the past few years, it went from an obscure academic subfield to a multibillion dollar industry in the form of prediction markets. More recently, AI superforecasters have come close to the accuracy of top humans, and their performance is rising rapidly.

[This is one of the finalists in the 2026 book review contest, written by an ACX reader who will remain anonymous until after voting is done. I’ll be posting about one of these a week for several months. When you’ve read them all, I’ll ask you to vote for a favorite, so remember which ones you liked] A couple of decades ago in Kabul, a fellow aid worker on his third beer came up with a vivid simile for what American money was doing to the Afghan organizations implementing USAID projects.

The annual prediction market conference was earlier this month. This was the year prediction markets went from an obscure hobby to a multi-billion dollar industry; from semi-illegal to having the President’s son as an advisor. I can’t remember if anyone talked about any of that. It didn’t even register. All eyes were on the AI superforecasters. I met an AI superforecaster startup founder who told me his AI had turned $35 into $2 million on Kalshi over seven months.

I. Having kids has given me new appreciation for old poetry. The first time I read Song of Hiawatha, I skimmed over the part in Book 3 where Hiawatha first meets his father Mudjekeewis: Filled with joy was Mudjekeewis When he looked on Hiawatha, Saw his youth rise up before him In the face of Hiawatha, Saw the beauty of Wenonah From the grave rise up before him.

The philosophers of the Frankfurt School practiced a technique called negative dialectics, where concepts are defined as much by what you can’t say about them as what you can. Appropriately, the Frankfurt School has ended up defined by what you can’t say about them. You can’t say that they invented a new form of left-wing thought called Cultural Marxism.

Sorry, I give up. In past elections, I’ve covered every single candidate for governor of California, from the incumbents all the way down to the cranks. In 2022 there were twenty-six of them, and I covered them all. But sorry, I give up. This year there are sixty. It’s too many. I can’t disambiguate them all into unique individuals with their own personalities, hopes, and dreams. So as consolation for the list I’m not giving you, here are the basic types, and a few examples of each.

“All exponentials eventually become sigmoids” is an annoying AI talking point.

Inconclusion, the only good theory of taste is Nostalgebraist’s. He wrote a post called Hydrogen Jukeboxes, analyzing the literary output of an AI called R1. This AI tried hard to write good fiction, which was part of the problem. It crammed its stories with what Nostalgebraist called (stealing a term from Ginsberg) the “eyeball kick” - a flashy stylistic move that immediately catches the reader’s attention and “wows” them.
