Benford’s Law is wild once you see it everywhere. Have you tried running it on any datasets yourself yet, like public company financials or tax data releases. Btw, let's connect and support each other!

Tomorrow at 7am AZ time I give grand rounds for University of Arizona in Tucson and the real over-arching idea I want to convey is in this book.

Today I learned about Benford’s Law: in real world data, roughly 30% of numbers start with “1”, whether it’s stock prices, city populations, or electric bills. forensic accountants use this to detect fraud, since fabricated numbers don’t follow Benford’s law.

10 RCTs,N=1142 ankle ORIF pts: cast 6% wound comps vs EFT 14%; RR2.14. Impaired healing 2% vs 4%, RR2.03; superficial infxn 4% vs 8%, RR1.87. Deep infxn/reop ns. ∴ early motion costs wound risk; for surgeons, favor ≥2wk cast post op.

davembennett What's the best predictor of world-class performance in runners?
Volume of Training.
You've got to spend a lot of time doing the thing if you want to get good at just about anything.
Same goes for Orthopaedics: the number of intentional focused thoughtful reps that you reflect on and learn from is what you should SEEK as a trainee. See and learn from every patient you can. Do it for your future patients.

It’s time to get rid of modules and drastically decrease all meeting so I can see more patients.

Animal experiments & 2D cellular models cannot capture human bone structure, disease heterogeneity, or clinical outcomes.

My only defense: audiobooks were much less of a thing when I started out, and when you read, your brain eventually sort of skips the dialogue tags. In audio, there's no skipping, you hear every single one. So it's far more annoying to just use "said" in audio. Anyway, now it's an addressed issue.

framing matters. In kids 36-83mo, N=279, permission to lie ↓ deception: Study1 3.79 vs 4.66 lies/6; Study2 adj OR 0.51; Study3 OR 0.36. For AIS brace wear, carefully framed limited off time may paradoxically ↑ adherence by activating duty norms.

I think of AI more like eyeglasses. Does my ability to extrapolate from a blurry field of vision suffer because I have these tools to help focus? Yes. What exactly is the benefit of being able to less correctly extrapolate from a blurry field of vision again?

‘Everyone is Replaceable’: Death Rattles Oregon Amazon Facility A worker died at Amazon’s Troutdale warehouse last week. Employees were told to look away.

For more than a week, Amazon has managed to keep a death at its Troutdale, Oregon, facility out of public view.

Workers I spoke to are pissed.

Re-watching Game of Thrones with my oldest, and remembering that this was 11.5 years ago, in between seasons four and five, joking that he needs to write.

I can’t remember who said it, but Martin is only going to be posthumously releasing the books. There’s zero chance they aren’t completed yet.

I wonder if this is the real reason economists think doctors are overpaid?

You can use AI to help you create highly reproducible mathematical formulas that predict the future even though that may not be your specialty.
