I should come clean and admit there were 2 weeks I couldn’t cross because the Hudson froze over entirely.

There was a river between the train station and my office and the choice was a 7 minute kayak or a 30 minute drive

And the nearest bridges were 7 miles in each direction

There was a river between the train station and my office

I really do mean every day too

This undersells the fact that you would sometimes do zoom meetings during the kayak!

I kayaked to work every day for 3 years

Definitely agree with all that too

The main thing I think AI is going to do is generically put pressure on all of these institutions. That opens up space for changes in general including ones that might not be directly tied to AI.

But who knows, maybe there's a "Big Short" style version of electoral shocks you could make

Something tells me this very legitimate agent may not have read my book

What’s actually going on in this statement is he’s using insider terms to sound credible to influential people within the defense policy community

There’s a lot of interbranch rivalry that ends up fueling weird terminology stuff like this

I think it can refer to marines too so possibly it covered most people who were in Iraq. But sailors and airmen definitely aren’t usually called that.

soldiers and troops are army specific

It’s a very common term in the defense world. It’s mostly just because you want a single term to refer to members of the army, navy and Air Force

Identification K9 puts professional ethics over personal attachments

Time to repost some causality memes #IdentificationK9

I remember reading a paper at one point that drew a distinction between polling vote share error (how far off the vote shares were) and polling narrative error (when the wrong party was said to be ahead). Does anyone remember the reference?

I haven’t had a chance to dig in but more recent evidence maybe looks more like an epidemic (may well change my mind again) bsky.app/profile/digt...

If someone has newer data that shows something very different I’m very happy to have my mind changed on this again. No one’s pointed to anything very conclusive that I’ve seen so far

Looking at a couple of panel studies my current working hypothesis is that sustained participation in panel studies decreases respondents life satisfaction.

Problem about the loneliness epidemic is, it's everywhere except in representative survey data. Let's look at where the claim comes from. 1/

Giving me flashbacks to the giant ISCED mapping spreadsheet I've got for one project

A world where 90% of people are getting degrees is a world where you’re sending a very strong signal by not getting one

In other words, high graduate premiums are compatible with a world where non-graduate prospects have worsened as credential requirements have increased for medium skilled jobs

I think it’s worth bearing in mind that graduate premium is a measure of difference not the level of achievement within the graduate group.

Great work in this paper figuring out the scaffolding to get this to work

I've been interested when we were going to reach the capability threshold for this.

Once the tires have been kicked, all social science journals should adopt computational reproducibility on submission.

Huge reduction in reviewer burden by eliminating a whole class of errors up front.
