Perhaps you should. It's obvious that all companies at very least desire to know who is the high performer and who is not. To deny that for a trillion dollar successful company is just ridiculous.
Well, this is what you stated previously: "there isn't any reason to believe that companies can or even <<<<want>>>> to identify the lowest performers."
And yes, there is at least some evidence to believe they do that identification somewhat successfully: their business is working.
Yes when I go to the store, I hope to find a million dollar gemstone in my loaf of bread. But is that evidence that my trip to the store was meaningfully motivated by this?
Anyway, I've made my point every way possible now, it's time to leave it and let those who understand, understand.
