The whole "false positives" narrative is an example of the "saying something enough makes it true" fallacy.

I've interviewed dozens of people, and you can easily root out false positives by asking about their prior experience. Simply probing about things like design patterns to challenges with Javacript front-end coding is enough. If the candidate can go into explicit detail about past projects including bugs they fixed and limitations they came across in a Angular 6 project (as an example), then that's usually a good sign they know what they're talking about.
