Terrific @scientificdiscovery.dev post on randomized controlled trials in @ourworldindata.org.

Including this important chart on the impact of pre-registration.

Magically, when people had to pre-register outcomes, many of the benefits disappeared.

A #SysReview of adverse events reporting in psychotherapy #RCT -s:
www.tandfonline.com/doi/full/10....

60% of 81 RCTs (since 2007) reported harmful effects.

Based on these data, one can expect adverse events to affect 1/10 (serious adverse events 1/21) patients.

Remember, if you encounter what seems like an implausible survey finding, ask:
1. Were survey respondents selected randomly or was this an opt-in poll?
2. Could the results, especially for young adults, be driven by bogus respondents?

New blog post! Why experiments are the gold standard for answering causal questions (pedermisager.org/blog/why-exp...). Many text books insist on experimental evidence to draw causal inferences bvut don't fully explain exactly what gives experiments their special powers.

this was the biggest and fastest win against a pathogen in medical history

also it was a brand new pandemic pathogen

simply awe-inspiring, if you understand anything about the promise of clear thinking and hard work to do good and achieve great things
To say that "the data show these vaccines fail" in regards to the mRNA plaform is unforgivable.

For those of you that don't remember - this is the data from a SINGLE dose. In December 2020. So good I cried in grateful tears.

Mistakes are a failure of systems, not people. In a working system, making a mistake is normal, but inconsequential. 🧵

Asking whether living in cities affects mental health is too simplistic.

In 500,000 adults, we find no universal urbanicity–mental disorder link.

Cities worldwide include very different living conditions & characteristics.

We need to identify which aspects of urban life harm or protect well-being
How does where we live – urban, rural, or in-between – relate to our mental health? 🌆🏞️

In this cross-national study, we investigate the links between urbanicity, anxiety and depressive disorders in 500,000 adults across the UK, Norway, and New Zealand 🧵
