I also struggled with this topic and found a video about this that helped me remember it. They talked about Sensitivity by relating it to “The Sensitive Scanner” aka the TSA scanners at airports that beep for a lot of people who don’t actually have weapons on them. So there are a lot of false positives. But if someone DOES have a weapon, it will always beep (true positive). So in that way, a test with high sensitivity is a great way to rule something OUT because there is very little chance someone who has the condition (a weapon in this case) would get a false negative.
High sensitivity = very few false negatives! Every time I see sensitivity I just picture the Sensitive Scanner as my visual.
I also think about pregnancy tests that advertise being “highly sensitive”. If you are pregnant, it would be basically impossible to NOT test positive. So it’s a good way to rule it out.
Hope that helps!
