"a ‚significant' p-value between 0.01 and 0.05 should be interpreted with the expectation that the effect is exaggerated by more than 50% (median 1.56) and that an exact replication has about a one-in-three chance of also being significant." evidenceinthewild.com/p-value-look...
The P-Value Got a Lecture. It Needed a Lookup Table.
Ten years after the ASA told us to stop misusing p-values, we're still arguing about thresholds. Erik van Zwet and colleagues did something different: they asked 23,000 clinical trials what a p-value ...

This is my favorite climate change chart. Japanese monks, aristocrats, and emperors kept meticulous records of cherry blossom festivals for 1,200 years and accidentally built the world's longest climate dataset.
Ecologists! I have received four sets of paper reviews back in the last month, and two had obviously AI generated reviews: @plos.org and @journalofecology.bsky.social. We also have reviews from @journalofecology.bsky.social that I strongly suspect were AI. Our peers are intellectually lazy.
A perfectly timed capture wins @nhm-london.bsky.social #WPOTY Nuveen People’s Choice Award. 📸 🎉 Huge congratulations to photographer Josef Stefan on this incredible capture of an Iberian lynx playing with its prey.
Power is not the ‘probability of obtaining a statistically significant result.’ It is this probability only if the true effect is equal to the alternative hypothesis used for power calculation and if all model assumptions are correct. Giving less power to statistical power doi.org/10.1177/0023...

Today we set up two insect monitoring stations in the glorious sunshine as part of a Masters thesis project. We will be comparing this with traditional monitoring to improve our understanding of the role of AI to supplement and enhance insect monitoring 🐝🪰🦋💚 @globalchangeeco.bsky.social
"The number of birds captured in mist nets plummeted by 40% between 2001 and 2014. Likewise, bird numbers fell by 50% during systematic surveys of birds by sight and sound. The most severe declines occurred among species that feed on insects."
Birds are vanishing from tropical forests. Is another ‘silent spring’ coming?
As mysterious bird declines crop up in the Amazon and beyond, scientists suspect climate change may be to blame

We promote relaxing long-held views of what a statistical interval does, or should, represent and see interpreting confidence or credible intervals as compatibility intervals as a step in this direction. Giving less power to statistical power doi.org/10.1177/0023...

A successful study should result in useful information about how compatible the data (and background assumptions) are with values large (or small) enough to be deemed practically important. Giving less power to statistical power doi.org/10.1177/0023...

My book is now published! 🌏🎶🧪 You can download it for free at academic.oup.com/book/62353 - I’d be grateful if you do! I also published an accessible summary with audio/video today in @nature.com: www.nature.com/articles/d41... Try reading that first, then give the whole book a read if you like it!
ERROR RATES ARE HYPOTHETICAL!! "They seem to bring an air of objectivity and comfort to an otherwise challenging and messy research process; but their roots inhabit the same soil as statistical hypothesis tests that have been criticized for decades"
