An ENTIRE podcast on collider bias 🤓🎉 - love it! Here is our take for gene x evironment studies! Can’t wait to listen! www.nature.com/articles/s41...

Gene-environment dependencies lead to collider bias in models with polygenic scores - Scientific Reports

Some said it couldn’t be done. That it was impossible; ridiculous; absurd. But @tomchivers.bsky.social and I have done it: recorded a whole podcast episode about collider bias. www.thestudiesshowpod.com/p/episode-57...

In response to the final few seconds in this podcast, that CB is something to be aware of but really hard to actually DO anything about. Here’s our suggestions in the genetic epidemiology context: journals.plos.org/plosgenetics...

Strategies to investigate and mitigate collider bias in genetic and Mendelian randomisation studies of disease progression

Genetic studies of disease progression can be used to identify factors that may influence survival or prognosis, which may differ from factors that influence on disease susceptibility. Studies of dise...

Indeed, great episode by @tomchivers.bsky.social & @stuartjritchie.bsky.social on collider bias & for criminologists worth checking this research note pmc.ncbi.nlm.nih.gov/articles/PMC...

Taking the problem of colliders seriously in the study of crime: A research note

We provide a brief overview of collider bias and its implications for criminological research. Owing to the nature of the topics studied, as well as the common data sources used to carry out much of t...

Collider bias is hugely overlooked in Criminology, both quant and qualitative research. This is one of the best explanations I've heard - definitely worth a listen. https://www.thestudiesshowpod.com%2Fp%2Fepisode-57-collider-bias&utm_campaign=aga&utm_source=agsadl1%2Csh%2Fx%2Fgs%2Fm2%2F4

This is such a silly straw man, and Carl (and everyone reposting this) should know better. The argument is that *to the greatest extent possible, science should not be political*. Everyone agrees that it IS political, but that’s bad! We should make it less so.

In case you didn’t know, I’ve been doing these monthly Substack link posts about bad science (fraud, the replication crisis, bias in science, dodgy journals, all that stuff). Feel free to subscribe, or to send me links to include in the next one! www.sciencefictions.org/p/science-fi...

Science Fictions links for October 2024

Including a good scientific report about the bad scientific reports published in Scientific Reports

Great example of bias and hype in scientific reporting and media coverage, thanks for highlighting @nbtiller.bsky.social Good chapter with lots of other examples of this in 'Science Fictions', by @stuartjritchie.bsky.social

Left, a non-randomized study showing that saunas significantly decrease arterial stiffness. Right, a randomized, crossover study, showing no benefits on arterial stiffness/blood flow. Note the colossal difference in media attention. In the media, sensational studies > robust ones. #science #media
