After this lesson, students should
- Understand that there is always the inevitability of a trade-off—for a given test, one can reduce the risk of false positives by increasing the risk of false negatives, and vice versa. You make this trade-off when you determine what the threshold is (e.g. convict someone if you're 99% or 70% certain that they're guilty).
- Understand that whether false positive or negative is preferable depends on a human values judgement on the consequences of either: (e.g. "innocent people shouldn't be in jail") and risks (e.g. dangerous people committing more crimes).
