Speaking as an officially-diagnosed zebra (Ehlers-Danlos syndrome), it took a year of doctor searching until I found a specialist who knew what to look for.. and it started with someone in a powerchair I met at a party remarking that my skin felt velvety like his.
Many doctors are bad at conditional probability. [0] 2% of the healthy population is hypermobile, and hEDS is ~1:5000. But P(hEDS|atrophic scars, spontaneous dislocations, 7/9 Beighton score, paralysis attacks) is much higher. There's a weird stigma against zebras seeking diagnoses because you almost have to do your own research to be diagnosed properly.

- taneq 8y agoYeah, I remember reading something about that in some introductory Bayesian statistics article. They asked a whole bunch of doctors the P(cancer | positive screening test) question and their answers were way off. Which is fair because it's pretty unintuitive, but also not good because they're using that intuition to make life-and-death decisions. By weird coincidence, I think one of my friends was recently diagnosed with EDS after a long, long search to find out what was actually going on with her.
