You brought a smile to my face. I came here to post this same point.

The piece is kind of making a basic fundamental mistake in measurement, assuming that all variability is meaningful variability.

There are ways of making the argument they're trying to make, but they're not doing that.

Also, sometimes a single overall score is useful. A better analogy than the cockpit analogy they use is clothing sizing. Yes, tailored shirts, based on detailed measurements of all your body parts, fit awesome, but for many people, small, medium, large, x-large, and so forth suffice.

I think there's a lesson here about reinventing the wheel.

I appreciate the goals of the company and wish them the best, but they need a psychometrician or assessment psychologist on board.
