- Medical science handles variation by simply assuming that large enough samples will average out variation. This loses a ton of information as the “average person” is a construct that almost certainly doesn’t exist.
- news media on medical science glosses over all uncertainties in the name of clickbaity sensationalism.
- lawyers are the incentivized by our adversarial legal system to adopt aggressively hyperbolic interpretations of the science to sue people and extract money.
- medical associations then tweak policies to protect against malpractice
Run this loop enough times and lots of noise gets amplified.
My hope is the AI+sensors ushers in the era of truely personalized medicine.
Well, this wouldn't even be that bad, if sample size were actually large enough.
My point goes beyond that one: yes, variance is a problem. But _even_ _just_ getting good averages, for all their faults, requires a bigger n than many studies have. Especially observational studies.
