Just to clarify, as others have pointed out, the leadership principles at Amazon are in no way a new experiment. I don't know their origins but I wouldn't be surprised to learn they are nearly as old as the company itself (probably a few years younger).

They are deeply engrained in Amazon culture. They are brought up frequently. They are used as the basis for both hiring and promotion decisions.

Regardless of whether or not you (or employees) agree with them. I think what's interesting is that you call them out as too long to be useful. But my guess is +90% of salaried employees at Amazon could recite all of them and give examples of what they intend to convey. I suppose this is a testament to Amazon HR?
