I've always found it a bit odd. When is that determination made exactly?

As an engineer the things I'm "right" about are often meaningless. When shit's started to really hit the fan and we're busy putting put production fires nobody cares. But for some perverse reason people still remember the architecture astronaut who devised said mess as being right. And I'm the one who's not a team player and just being difficult.

I think this one's for the managers and "rockstar" engineers.

No, read it again.

"Leaders are right a lot. They have strong judgment and good instincts. They seek diverse perspectives and work to disconfirm their beliefs."

Work to disconfirm their beliefs - this is the key. It shouldn't be "Are Right, A Lot" but more "Get's Right, Consistently." In practive, this means working to check your assumptions and actually ensure you're ... right.

lol. you don’t know the lore young padawan.

great leaders frequently change their mind based on new information. so, by definition you are either right because you changed your mind or dumb for sticking with the wrong thing.

that’s some revisionist BS right there, but can you trust someone that is not right? like a LOT!

tbh this is one of the ones that is basically ignored by strained interpretations. i.e., there's a saying that "people who are right a lot are also wrong a lot" which... sort of undermines the plain text of the principle.
