There's not enough information to know what "85% accuracy" means. Is that false positive, or false negatives, or a combination of both, or misreporting?
I agree that presenting risks as percentages instead of real numbers is misleading.
But they say this device is better than primary care doctors so I'm not sure what that says about primary care.
Gerd Gigerenzer wrote a book in 2002 about clinicians inability to understand percentages and screening tests.
Only that primary care providers are not specialists.
But your point is important: is using this device as a gateway to dermatologist referrals a good thing.
