I see this as a negative, kind of like police profiling, or lie detectors.

Sure it's cast here as a 'good thing', but in the long run it can get pretty ugly. People perceived by the fallible system can be the first to be let go, less likely to be promoted, etc, and I think that's where the majority of action in this area will wind up.

The biggest problem is that because the system is so fallible people will be miscategorized.
