For the last 50 years, we've designed cars to be safe...

For the 50th-percentile male.

We love a good 'association as as fluid' metaphor, but this guy takes it to the next level.

12/10 for the reminder that conditioning on a collider doesn't just mess with your identification; it can also flood your basement.
I built a DAG diagram with garden hoses for teaching.
Pictured: a collider bias diagram, inspired by a blocked pipe situation I experienced (which I credit with giving me the intuition though it also ruined my belongings in the flooded cellar).

Lovely interview! We always preprint our analyses coming from @estbiobank.bsky.social, and personality X job satisfaction is no exception!

@renemottus.bsky.social
For Maris Vainre & coauthors, sharing their preprint led to coverage in New Scientist, 1,800+ downloads, & invites to discuss their work.

Their study explores whether people in certain professions are more or less satisfied with their jobs & lives. Read more in our Q&A!

Whoever wins the #worldseries tonight is going to make a legion of fans for life
The psychology of fans &identification with teams is fascinating
Like goslings, boys imprint on the team that wins when they are young. A championship leads them to identify with a team for life, especially boys 8-12

Can apple cider vinegar make you lose weight?

Probably not. My piece this week takes a look at a fascinating example of unreliable science, forensic metascience, and seriously problematic data.

Cool educational thread on vitamin B12
🧪🍎📃
Vitamin B12 is a rather unique vitamin.

Only certain bacteria and archaea can make it, not plants or animals.

Animals require B12 and can obtain and store it, which is why meat and fish are well-known sources for humans.

But what about non-animal foods? Can they provide any B12 at all?🧵⤵️
