Two, that the claim that “I had measles as a kid and I’m fine” is a flagrant example of survivorship bias.

Survivorship curves show female right whales can live to very old ages, but humans are causing North Atlantic right whales to die well short of their potential.

Plotted for comparison is the U.S. survivorship curve for women as estimated by the Social Security Adminstration.

Using these photos, we developed what scientists call “survivorship curves” by estimating the probability whales would disappear from the photographic record as they aged.

From these survivorship curves, we could estimate maximum potential lifespans.
