ah yeah, i'm glad you mentioned this because that's the one thing i forgot to include in my original comment: former mckinsey people seem to only tell you what they think you want to hear. they're the ultimate sycophants -- and my experience is that they're the best that money can buy for the task of telling you that you're right, especially when you're completely wrong.

it's a real pain, especially when you don't have enough information on an issue to form an opinion yet. you'll get all kinds of probing questions trying to sneakily suss out exactly what you're expecting to see or which way you want them to affirm your opinion on the subject at hand. it seems like their target customer is always someone who wants to add legitimacy to their bad ideas, and they will treat you as such even if you don't want to fit that bill.

they're incapable of being objective regarding facts of reality because their mental model for truth is that something that is "right" or "true" only per the opinion of whichever authority figure is the most salient at the moment. it explains a lot about why they're so amoral. it also explains a lot about why they fit in so well to the world of the elites: they're not ever going to have the moral gumption to speak truth to power... or even to the disempowered.
