The Skill AI Can't Replace: Judgment for Chiefs of Staff

This is the last piece in a 4-part arc on managing the AI you didn't hire. We covered how to find it, get your team to use it, and supervise what it does on its own. All of it points at the one thing you can't hand off: your judgment. AI drafts the memo, summarizes the deck, models the scenario, and flags the risk. The judgment about what matters, what's worth the risk, and what your executive needs is where you earn your seat. That call is the whole job.

I use AI right up to the edge of a decision, then I stop. Before a hard call, I have it lay out the assumptions I'm resting on, the strongest case against what I'm leaning toward, and who loses if I'm right. It's caught blind spots I was too close to see. The call itself always stays with me. The moment I catch myself wanting it to just tell me what to do, that's my signal I haven't thought hard enough yet. AI sharpens whatever judgment I bring.

In Deloitte's 2026 Global Human Capital Trends survey, 60% of executives now use AI to support their decisions. Ask them what skills matter most as AI takes on more, and the top answers are judging the quality of AI's output and critical thinking. As the tools handle more of the analysis, the judgment about whether to trust it and what to do with it is what's rising in value. (Deloitte Insights, 2026)
