Business school professors trained an AI to judge workers' personalities based on their faces.

It was "scientific" when they'd "confirm" it with stats.

What they call AI today is a family of obscure statistical instruments pretending to carry truth in that trait alone.

No, other than having stats you should also know and be capable of proving how those stats apply to the task at hand.

And they use the all-powerful electronic computation machine as a piece of technomagic to give it credibility.

Have you read Klemperer's book on Third Reich's language? I recommend it highly. Nazis used a lot of names for their policies, the subtle semantics of which are usually lost when translating from German. They used terms from radio and from automobile industry, for example.
