You regular reminder that millions has been spent on research into therapeutic benefits of insert placebos, to no avail, mainly because scientists who should know better still believe that the rooster crowing must make the sun rise.

You wouldn't promise such things even in your grant application (which are always overly optimistic).

But nevertheless he said by September we will know. Not sure what knowing means here

Never got such a lot of feed back on any of my work. Even personal emails and ofc letter to editor from a panel of keen&offended arthroscopists.

Letter and response better fun than the paper itself

Regional variation in low-value musculoskeletal surgery: a nationwide study from the Finnish Care Register | Acta Orthopaedica

actaorthop.org/actao/articl...

We examined temporal and regional patterns of low value operations in Finland

Rates are declining but we found large regional disparities inconsistent with variability in morbidity.

Hospital size and past incidence (treatment culture) explain variance

What happens if we don't operate people with failed nonoperative treatment?

They nevertheless recover.

Ineffective surgery does not magically become effective if other treatments are ineffective.

Unfortunately, they cannot.

Aluksi ajattelin kirjoittaa siitä, miten oikeistopopulismi toimii. Mutta te tiedätte ne kaikki jo: vastakkainasettelu, uhriutuminen, huomion kaappaaminen.

Joten käänsin kysymyksen toisinpäin: miksi sen vastustaminen ei toimi?

If you ever wondered how the KGB manipulated foreigners and got them to repeat Soviet propaganda, spend some time listening to Steve Witkoff talk about his wonderful conversations with Vladimir Putin.

What’s in the millions of tonnes of sludge spread on to UK farmland? Toxic waste – and ministers don’t care | George Monbiot Water companies let waste disposers, for cash, dump their loads into sewage farms. When it is recklessly used as fertiliser, we are all at risk, says Guardian columnist George Monbiot

I don't often ask people to write to their MPs. But I think they might listen to you on this, as it's so jaw-droppingly awful, and they're almost certainly unaware of it. www.theguardian.com/commentisfre...

A pro-Russian MP asks the PM of Estonia why when he uses Google, he is shown ads for "same-sex sex toys" and "swingers clubs."

PM Kristen Michal then explains how the Internet works. Algorithms track your prior activity and customize ads to display your interests.

It is also possible that other factors explain most of the observed variability and the effect could be (quite) constant, right?

Karelia, once seized from Finland, now ranks as Russia's most depressive region. In contrast, Finland consistently tops global happiness rankings. This reflects the Russian tendency to conquer territories at great human cost, only to neglect them afterward.
