Saying I don't know
Admit uncertainty out loud instead of producing a plausible answer
Answering a question you cannot answer with three words rather than an improvised paragraph. Sinek treats it as the substance of psychological safety: if the person in charge can say it and keep their dignity, everyone below them can say it too. The alternative compounds. People act on a confident wrong answer, and they had no reason to doubt it. He pairs the habit with a mentor's move, replying what do you think, which sends the question back to whoever raised it.

Sinek calls the confidence to say I don't know the single best thing he ever learned, after years of believing a leader had to have every answer. He ties it to psychological safety: if the boss can admit it, so can everyone else.
