I'm a cynical realist who held the same viewpoint as you: "everyone's a fucking liar. Can't they see all the shit that's being peddled is just bullshit?"

Then, I stopped worrying and loved the grift.

It's just a game to play.

I shelter my intellectual "honesty" and idealism within my side-projects.

For business? I play to win.

It's the only way I've found to stop myself from becoming a jaded hollow husk.

Escaping the KPI game? There are organizations that don't self-fellate with KPIs (rare, or impossible, as it may seem). I've found that the "corporate bullshit" curve follows the Dunning Kruger curve (with fat tails). You have the vast bulk of bullshit in the center, the average SME/Enterprise, where everyone is trying to peddle bullshit faster than their competition. On one end you have the "high-performance," "we're making obscene amounts of money, and we want to make even more" a la buyside high finance (note: there is a lot of "playing the game," but the game isn't as petty, because people have real shit to do, with a lot of money at stake). On the other end you have the "we're growing. We're making money, and we're busy getting more features out the door; we don't have time for this bullshit that pretends to be working" start-up type where everyone knows how much everyone else is "outputting." There's no room to coast; there's no layers upon layers of bureaucracy and bullshit metrics to disguise your actual worth to the org.

If neither of those two fit your temperament, then perhaps you should find a research outfit? There will still be games to play, however.

If you generally view most people as incompetent, and that you're constantly having to bear the brunt of the terrible decisions of those above you: you should start your own firm (or find more competent people to work with).
