comment Statistics: Why doesn't the probability of an accurate medical test equal the probability of you having disease?
Back in the real world, most medical tests don't have a simple "right 90% of the time" state: initial screening tests are chosen to have a very low false negative rate, for example, while they may have a higher false positive rate. This preserves resources, as the more expensive and precise tests are used only on those who were found positive in the initial screening. Furthermore, you don't care about the incidence of the condition in the population at large: you care about the incidence in the population being tested.
