Hidden Power

How Boards and CEOs Win the AI Era: Human Judgement, Cognitive Agency & Relationship Capital

Published by Amplify, in association with Thinkers50. Publishing 1 November 2026.

Every board in the world is racing to adopt AI. Almost none of them can answer the only question that matters: what happens to the humans who decide?

Hidden Power by Dr Kate Barker — hardcover edition, gold-foil title on a white cover.

The night the missiles came, I was at dinner on the 24th floor of The Link at One Za’abeel. The news moved across every phone at the table, and the remarkable thing was that the room kept going. Deals kept being discussed. Introductions kept being made.

Somewhere over the Gulf, the world was changing shape, and forty of the most powerful people in the region simply absorbed it and carried on.

That is where this book begins, because that is what the AI era actually feels like from inside the rooms where the decisions get made. The extraordinary has become ambient. The signals never stop. And the leaders who win are not the ones who react fastest to what is racing across the table. They are the ones who can still tell which of it matters.

The scenes that made me write it

I have spent years inside boardrooms on four continents, from sovereign wealth committees in the Gulf to technology boards in Europe and North America, and the same scenes kept repeating until I could no longer pretend they were exceptions.

A chair asks her board a simple question: now that the AI programme is live, who owns the decisions it makes? The silence lasts eleven seconds. I counted. The programme moves two billion dollars of exposure, it was approved eight months earlier, and not one person at that table can say where the accountability went. It didn’t disappear. It moved. And nobody in the room knows where.

An executive team spends an hour agreeing enthusiastically on a strategy. Then, one by one and in confidence, five of the seven tell me they think it will fail. The alignment I watched was a performance staged for the machine-made numbers on the screen. The strategy everyone applauded has no owner and five quiet opponents, and it is about to consume three hundred million dollars.

A chief executive, one of the most impressive people I have worked with, reads a recommendation to his board with total conviction, and halfway through I realise he is not summarising his judgement. He is reciting the model’s. He has stopped noticing the difference. His brilliance is exactly what makes it invisible, because everyone in the room assumes the thinking is his.

If any of that feels familiar, it should. It is happening in your organisation right now.

The uncomfortable truth

The advantage in the AI era does not go to whoever adopts the technology fastest. Adoption is now table stakes; your competitors have the same models you do. The advantage goes to the boards and chief executives who can still think clearly when the machine sounds certain, because as AI makes capability abundant, what becomes scarce is stubbornly human: the judgement to know when a persuasive answer is wrong, the cognitive agency to remain an active thinker rather than a fluent approver, and the relationship capital that carries a hard decision through an organisation when the data alone cannot. That is the hidden power. Most institutions are trading it away without noticing, and they will not discover the cost until a decision that mattered goes wrong with nobody’s hands on it.

What you will take from it

By the last page you will know where accountability actually sits in your AI-enabled decisions, and where it has silently moved. You will know how to spot performed alignment before it costs you, and how to tell when a leader’s conviction is borrowed from the machine. And you will hold the two instruments I use inside those rooms: the Board AI Index, which maps an institution’s readiness and oversight across five levels from Reactive to Integrated, and the Executive Cognitive Advantage Index, which maps the five human dimensions on which a leader’s performance now turns. The stories are mine. The evidence is bigger: doctoral research across six thousand executive leaders worldwide, and advisory work spanning heads of state, sovereign programmes and more than one hundred Fortune 500 companies.

Who it is for

Chairs and boards governing AI-enabled transformation. Chief executives deciding what to hand to the machine and what to keep human. Sovereign and institutional leaders whose decisions must stand up to scrutiny operationally, reputationally and historically. If you have ever sat in a meeting where everyone agreed and nothing was true, this book was written in that room.

The technology was never the difference. We are.
