I'd be curious about what method was used when he "monitored the IQ of workers throughout the day." I don't think I've ever heard of an "instant IQ" test that was anything but a parlor game/joke.

Maybe he emailed them a test periodically? If they answered quickly they were "less smart?"

A fairly well-known consultant, J. M. Juran, from many years ago produced a monster "Quality Management" handbook in which he propounded something to the effect (paraphrased from memory):

"It doesn't matter if the employees who do the work believe that your methods will work. You must determine what manager is primarily responsible for paying your consulting fee, and impress him."

(Of course, the new edition probably says "him or her" but this was 25 years ago.)

This sounds like a "consultant report" to me.
