Accuracy rate isnt a good metric for tests for rare diseases, a much better metric is sensitivity. Sensitivity is the measure of positive result accuracy. Which in this case is .0033%. This test would be more of a screening for a more expensive test than an actual conclusive result.

there's an issue with the original premise though, as 97% accuracy doesn't necessarily tell you if it's about false positives or false negatives

The flaw in this logic is that you are assuming that you are testing at random and not testing people who have signs that they have it

i agree, its not intuitive, but the explanation is still simple. the disease is simply so rare, that a false positive on a farely accurate test for the disease is more likely than actually having the disease

they probably tested you because you showed symptoms. your chance of false positive is 3%

the problem is: statistics don't matter for a single person. it doesn't help the one infected that his chances of actually having the disease were slim.

You forgot one important aspect: if you are tested for that disease, there is already reasonable suspicion you could have it, which raises the chances you actually have it on a positive result immensly.

You're kinda ignoring the possibility of false negatives here in a "realistic" scenario.

Yeah but if you show symptoms of the disease the chances would go up no?
