No, I meant the false negative rate. Imagine you have a hiring process. It marks some applicants as "should hire" and some as "shouldn't hire". False negatives are marked "shouldn't hire" when really you should have hired them.

The only way to determine your false negative rate is to hire a bunch of "shouldn't hire"s and see how they work out.

Easy hire, easy fire is inhumane to people who believe that once you get one job somewhere your problems are over. Never-hire-because-we-never-want-to-fire is inhumane to people who interview poorly and do good work -- they're humans too. You can't win them all.
