I made a #Shiny app about post hoc power and effect-size uncertainty. If you accept an observed effect, you also need to accept its uncertainty. The app shows how power wobbles when you consider the CI, not just the estimate. Embrace the #wobble #samplesize open.substack.com/pub/mzlotean...

🚨 Come to iIIRG 2026 to hear our talk about better methods to analysing interview data! @drcodyporter.bsky.social @mattansb.msbstats.info #belgium #conference #methods #investigativeinterview

2026 is shaping up to be another year with lots of new research!

Is there a teaching & learning part of Bluesky? www.linkedin.com/posts/cody-n...

Currently a lot of attention is going to get people to preregister, to check preregistrations, and noting deviations. But the most important step will be evaluating the impact of the deviations! There is almost no work on this. Good topic for a young metascientist!

Our #openaccess paper on the Tree of Life methodology in a UK secure forensic inpatient setting is out in #CurrentPsychlogy ToL supported identity development, and fostered shared understanding & community. See link: link.springer.com/article/10.1... #ForensicPsychology #MentalHealth

The Perspectives on Scientific Error (#PSE8) conference was great - I will be coming back. It was nice meeting so many new people, and getting the opportunity to discuss statistical, philosophical, and meta-scientific issues of scientific error.

This was a banger of a talk.

Insights from the #PSE8 conference Day 2: I was particularly struck by a presentation from Prof Leif Nelson on the detection of problematic data. I wonder how many of us have came across problematic papers - or datasets and don’t what to do!? #ResearchIntegrity #OpenScience

Insights from the Perspectives on Scientific Error (#PSE8) conference 🧵 Day 1: what a thought provoking morning. Replication remains one of the cornerstones of scientific progress, yet replication studies are still notoriously difficult to publish. Many never make it into print at all.

Everything is ready for the Perspectives on Scientific Error conference that starts tomorrow in Leiden! I look forward to hanging out with the mix of metascientists, philosophers of science, and statisticians! So many old friends will be there (and hopefully some new ones)! #PSE8

Compositional data (proportions that sum to 1) behave in ways standard models aren’t built for I walk through why Dirichlet regression is often the right tool & what extra insight it gives using a real ex of eyetracking #Dirichlet #r #brms #guide #eyetracking open.substack.com/pub/mzlotean...

WhatsApp responded to the findings of our new Cambridge Trust and Safety index: "WhatsApp said in a statement that it welcomed the research into an industry it said was "aiming to mislead internet services." Unsurprisingly, X did not return messages seeking comment www.reuters.com/business/med...

It was a pleasure to present at the Decepticon 2025 conference!! 🔗 Presentation slides: www.linkedin.com/posts/cody-n...

I'm privileged to be able to teach psychology to the Forensic Science students in their final year at @UWEBristol . If you're considering studying with us at the, I can wholeheartedly recommend this course!! www.linkedin.com/posts/cody-n...

Our discussions were around toxicology, changes in legislation, confirmation bias in the courtroom, typical errors that crime authors make, and that is to give a few examples! If you’re in the Bristol areas I would recommend these ‘Desert Island Books’ events. www.linkedin.com/posts/cody-n...

Hey #Criminology folk, Does anyone know of any research on how the #policing of different age ranges within populations impacts on how we understand the Age/Crime curve?? #LifeCourse #DevelopmentalCriminology #CriminalJustice #Desistance

To test mediation in an experiment, it's not enough to just randomly assign participants to X. Manipulating both X and M is ideal, but if you can't, this paper shows you how to perform sensitivity analyses that quantify how much confounders fucked up your model. journals.sagepub.com/doi/full/10....
