Thanks for the idea for this paper, and pushing it through to the end, Awais! The topics are challenging even without coauthors with numerous assorted opinions, and you should be so proud of having pulled this together so neatly. Amazing work, truly.

"Journalism is the natural enemy to nuances"

Just highlighting that this wasn't a particularly nuanced post.

There is amazingly scientific pop science (which is the real art), and fantastically nuanced journalism.

International Women’s Day is a good moment to recognize the many women whose work, mentorship, and leadership shape science and academia, despite many structural barriers. I'm grateful for the colleagues, collaborators, and students I get to learn from every day.

Kurze Klarstellung: ich werde in der ZEIT leider falsch zitiert.

Ich schrieb, dass Depressionen sich dadurch auszeichnen, "dass Beeinträchtigungen vorliegen".

ZEIT: "dass man nicht mehr funktioniert".

Wichtiger Unterschied. War keine Absicht und wird korrigiert.

The observed smallest worthwhile difference in this study "means that the current 15% antidepressant benefit over no treatment was sufficient for 1 in 3 people to accept antidepressants given the burdens, but 2 in 3 expected greater treatment benefits."

So, is membership in Sigma Xi worth paying dues for? I've been nominated and am curious what folks think. #academicsky

I’ve decided that the whisper network functions much more efficiently as a shouting network. Whispering protects the system and those in power. Shouting increases personal vulnerability but is the only viable path to actual change.

Unmasking Academe’s Gilded Boys’ Club The Epstein files reveal an elite, chummy, and venal scholarly network.

“the Epstein files highlight issues that women in academe have mostly discussed in whisper networks: Who is unsafe to be alone with? Which advisers are to be avoided? Whose connections may come with a price?”

My effort to reproduce this paper began as part of the Institute for Replication’s ongoing project to systematically examine the reproducibility and robustness of papers in Nature Human Behaviour3; my participation in this endeavour was approved by the Ethical Review Board of Vrije Universiteit Amsterdam’s School of Business and Economics. Inspecting the paper’s first two figures revealed a mathematical impossibility. There are nine EU countries that experienced zero terror attacks during the study’s time frame. However, the paper reports that the inverse hyperbolic sine of these countries’ per capita attack rates are positive, and increase or decrease over time. This is impossible; the inverse hyperbolic sine of zero is zero4. The main outcome variable displayed in the paper’s second figure is hard-coded in the replication data as ‘DVSin’. Figure 1’s top row of plots shows that DVSin is negatively correlated with both terrorist attack rates (r = −0.107, two-sided P = 0.024) and their inverse hyperbolic sine (r = −0.108, two-sided P = 0.022). These plots also show that in the 305/420 country-year observations after 2006 experiencing zero terror attacks (72.6%), DVSin takes on 292 different positive values. This implies that the paper’s main outcome variable cannot possibly be constructed as described in the paper.

"the paper’s main outcome variable cannot possibly be constructed as described in the paper."

Retraction of 2023 paper that did not use the reported variables. The replication report is astonishing www.nature.com/articles/s41...

I don’t think it will be totally ineffective, but would rather see long term solutions that actually tackle the issues. Bans are at best a bandaid.

It’s not a good faith solution that actually tackles the problem and effectively protects vulnerable people.

Bans may also actively harm some youth (eg for LGBT folks in very rural US areas, social media is the only way to connect).

Excellent summary of validity threats (in this case to internal validity) in a clinical trials, where some common decisions researchers make basically break the benefits of random group allocation.

Believing that blocking a few apps or sites changes how folks engage with content is convenient fiction. Kids will instead move to alternative apps or sites which parents have less access to / control over.

Also, what about other vulnerable groups in society other than kids?

From UK campaign to ban social media <16: “The idea that this can be fixed with better parenting is a convenient fiction. You can’t out-parent a business model.”

But you can regulate companies, eg no ads on social media for kids. There is nothing on social media that isn’t elsewhere on the internet

In contrast, time spent on one's phone was not significantly related to mental health. Therefore, transition patterns across different technology activities may have clinical relevance beyond time spent or specific activities engaged with.
