This year definitely didn’t turn out the way I expected in January, but predictions predict the future, not what we thought. That’s kind of their point, actually. So here’s how I did, on this list. (I have had a number of other prediction sets, this just judges my 1-shot predictions…


People should predict things, it’s crazy that more people don’t, yadda yadda yadda. But I will say this seems to be changing — more and more people are on board with this idea. In any case, this is now my 5th round of yearly predictions — On Medium since 2017


If you have a belief, you should be willing to bet. It’s useful as mechanism to ensure people’s claim aren’t empty signalling. It’s also good as a way to check that your claims are concrete enough to be resolvable, and that you don’t change the way you score your predictions…


Well, it’s that time of year again, when most famous prognosticators around the world given imprecise and non-judge-able claims about what the world will look like, and if they’re wrong, no-one will know.

The few and the proud, however, are willing to put our (mostly non-existent) reputations on the line…


Here’s my Annual Review.

I mark each True / False, and sometimes include [notes at the end.] Obviously, not all predictions can be scored yet, but this is for the items I do know. (I will remove /modify this line after I’ve updated again.)

I am once again making a yearly set of public predictions which I will publicly score early next year, as I did last year and the year before (as well as in other formats and/or less publicly in various forums…


Medium is now gated. I’ve moved. Non-gated post replacement link.

OK, it’s (slightly after) that time of year again, and I need to make my new predictions. But you can’t improve unless you figure out how you’ve been doing, so here’s my review of last year’s predictions. …


A recent story said that there was a terrorist “planning” to attack the Italian town of Macomer (pop. approx. 10,000) by putting Ricin and Anthrax in the water supply. That sounds scary, right?

First, he didn’t HAVE Anthrax or Ricin. He was planning on buying it online. Somehow. (No, no-one…


Blockchain enthusiasts have occasionally claimed that blackchains allow “an asset without a liability,” a phrase used by Walker and Luu, and echoed by Nic Carter. Despite being a ledger, the blockchain is not money owed by anyone — which is a informal understanding of what a liability is. …


This is a simple point, but one that gets overlooked, so I think it deserves a clear statement. Morality is less effective than incentives at changing behavior, and most of the time, policy is the way incentives get changed.
