Sensitivity and specificity: alien edition: a light-hearted look at statistics.

Zoltan: Captain, since Org “enthusiastically landed” our ship, I have successfully repaired all our equipment except for the tricorders. While they are highly reliable in identifying which humans are pregnant, their compromised power supply won’t last until the planned abduction date. We are, therefore, evaluating other potential identification methods. We will use the tricorders as the gold standard to measure the effectiveness of the other methods. Then we can use the other methods on abduction day.
