[Science]Watson Better than MDs at Diagnosing Cancer

Simple probability:

Suppose the doctor is wrong half the time. Then there is only 25% chance both doctor will both come up with the wrong opinion. Assuming you find two doctors independent of each other.

 

medical imaging equipment (like mammography systems) already use aided detection software for potential areas of problem.
and most doctors use it for that reason... just incase of misdiagnosed lawsuits.
using multiple sources to find problems lowers misdiagnoses.
