To elaborate on this a little in a health economics context: I do some work on the effectiveness of algorithmic prediction on pt outcomes. Identifying both mechanisms and outcomes is an *incredibly* complicated process, not least because patients are always being intervened upon. >

Where have all the comments gone?
For decades, the American Economic Review regularly published formal comments — papers that replicate, reassess, or challenge earlier AER articles.
In our latest blog post, we show: they’ve nearly disappeared.

This is stenography, not news reporting. The BBC ought to provide some context, such as putting the scale of the changes which Reform claim are possible into context. This omits the major policy of revoking ILR and deporting legal migrants at unprecedented scale.

mainlymacro.blogspot.com/2026/02/how-...
'Tilting left' won't help. Labour has lost much of its base not so much because it hasn’t been left wing enough in economic terms, but more because it has sounded and acted in an illiberal way.

Interviewers were paid per interview, not per hour, so they nudged respondents to skip those questions. Make the question less burdensome, train or monitor interviewers, or (radical idea) pay them properly and missing friends reappear. 3/

Weekend plug for my new personal post: Why does regulation often feel so toothless?

Sometimes regulators are just useless, but more often the problem is that governments don’t give them the tools or the powers to deter bad behaviour

Today we’re looking back at Episode 165: ‘Dark Star’ by the Grateful Dead.

Cocking in at 4.5 hours long, Andrew delves into the career of the American rock band - but also the historical and cultural context.

A reminder to the news media: “conflicting accounts” is what you say BEFORE the incontrovertible video evidence appears. After that, your job is to ask why one side is lying, not to repeat the lie and pretend no one knows the truth.

The BBC coverage is absolutely terrible.

It leads on "sharply contested narratives"

It has a dramatic skew to the US government

It has posted the video but has failed to report on what it shows: it shows the US govt account is untrue

So this is sort of fascinating because on the one hand obviously the Roman imperial senate was a shadow of what, say, the Senate of the third and second centuries BC had been, but at the same time it was a pretty crucial component of imperial governance into the third century.

You can see some of these stereotypes - the simple, morally pure countryside vs. the morally compromised, inauthentic city - play out in Greek and Roman literature.

So this is a very old idea that recurs regularly.

When asked, most people (72.4%) living near lynx in Norway say they LIKE living with lynx. Just 8.3% say they dislike lynx. In Scotland, where we're currently denied the opportunity to live near lynx, the majority of people WANT to see lynx reintroduced.

James Watson, dead at 97, was a scientific legend and a pariah among his peers James Watson, the co-discoverer of the structure of DNA who died Thursday at 97, was a scientific legend and a pariah among his peers.

A Sharon Begley byline, almost 5 years after her death.

Upon hearing the news James Watson had died, a STAT reporter said in our Slack, "I wish I could read what Sharon would have written."

Incredible news: Sharon in fact did pre-write a Watson obit. And it is masterful and excoriating.
