The West has been below replacement level fertility before. By the 1920s, more than half of European nations had fertility rates below 2.1. But fertility recovered – often to far above replacement level – in the famous Baby Boom. How did we pull it off? (🧵)

Several research teams are currently testing gene therapies to treat congenital deafness.

Vaccines have saved over 150 million children over the last 50 years, and have been a massive driver of reductions in infant mortality.

New article by Hannah Ritchie on a major recent study:

'Sneaked references: Fabricated reference metadata distort citation counts'

This, in our view, is a very important paper.

We recall reading a preprint and glad to see that it is now published. buff.ly/3QAPsaC

- No confidence regions in the plot
- These are parent reports
- WhatsApp is considered “social media” in this analysis
- Note that the US has an age limit for social media (13) via the Congress in the Children's Online Privacy Protection Act.

Hey Berlin people and beyond -- I will give a talk at the Berlin Epidemiological Methods Colloquium (Berlin Epi Methods). If you want to join us, you can find registration links for both in-person and digital attendance here: bemcolloquium.com/meetings-calen…

Old thread, but super important work - both due to the elegant technique used to arrive at this answer (which has key applications to trials I haven't seen people exploit yet) and due to the result (which points at prognostic covariates to increase power in longitudinal designs)

Now published in Nature Mental Health!

Main difference since the first preprint was posted: we now have results for #autism as well! Results are similar to Bipolar and OCD 🧵👇

New meta-analysis in The BMJ about the treatment of depression with psilocybin🍄
Despite its positive conclusions, the authors make the most recurrent errors in meta-analyses

Let's see if by pointing them out we can make them less and less frequent🧵

This is the second meta-analysis in psychiatry I've seen in the past 2 months that (very likely) confuses standard errors with standard deviations, leading to ridiculous effect sizes.
The BMJ has an impact factor above 100(!). Neither the reviewers nor the editor noticed that…

N=33 per cell, no prereg, data on request, no blinding, d=.62.
these figures negatively affect my scientific body image; they're too perfect.

Vielleicht haben viele hier (so wie ich) an der Uni gelernt, dass Belohnung die intrinsische Motivation zerstört.
Stellt sich raus: diese Annahme beruht auf wenig bis gar keiner wissenschaftlichen Evidenz und Fehlinterpretationen der Literatur durch Deci und Ryan.…

Ignazio Ziano Huh... too many scales you say....

One of the major criticisms of operationalism is the uncontrollable proliferation of concepts. Ironically, psychology is experiencing a massive proliferation of constructs even though modern psychology tends to follow a realist approach to measurement.

The reduction of child mortality is one of the big achievements of our time.

But it is hard to celebrate something that is *not* happening. So, for my new article, I turned things around.

👇This is the main chart and takeaway.
