From Certainty to Wisdom

By Nathan Waterhouse · 2026-07-07

It was late in the afternoon, the part of a long workshop where people stop choosing their words carefully, and the same argument had been circling since before lunch. By now it was down to two of them, both on their feet while the rest of the room stayed seated. One was getting tense, his voice tightening each time he came back to his point, as if the room's failure to agree with him was a thing being done to him. The other was more generous about it, arms wide, palms up, conceding ground, nodding, and then arriving back at exactly the same position, certain he was right. Everyone else had gone quiet.

I was at the flipchart, trying to capture it, my breath still slightly caught from the tension.

The argument was not really about which of them was right. Both of them knew the other had a point. Neither could afford to say so without sounding as if they were folding.

Then someone who had not spoken for a while said, "Guys. It's both, and." Not either. Not but. Both, and. It landed oddly at first, almost too simple, and you could see the two of them turning it over, working out whether they had just been let off the hook or handed something harder. Slowly, once they understood what she meant, the tension began to ease.

It could have been a weak compromise. It wasn't, though it took me a while to see why. I have often imagined wisdom as a kind of calm, monk-like certainty. The wise person knows what to do, sees clearly, cuts through the noise to the answer.

Lately I have started to see it differently. One way of looking at wisdom is as the capacity to hold opposing truths without collapsing too quickly into one side.

The psychologist Igor Grossmann has spent years trying to measure wise reasoning, and what he finds is that it looks less like knowing more and more like a particular way of thinking: recognising more than one point of view, admitting the limits of your own knowledge, accepting that things change. What his work does not find is that age reliably delivers this. Growing older does not make us wiser by default. Some people harden as they age, more certain, more attached to a single view; others grow more able to hold competing perspectives as each carrying part of the truth. The difference between them is not intelligence. It is whether they can stay in the tension rather than rush to resolve it.

The seduction of certainty

Certainty is comforting. It lowers anxiety, it gives us a feeling of progress, and in organisations it is rewarded. Leaders are expected to have answers. Strategies are expected to appear coherent. Transformation plans are expected to show milestones, owners, outcomes.

There is nothing wrong with clarity. People need it. But clarity and certainty are not the same thing. Clarity says: here is what we currently understand, here is what matters, here is the direction we are choosing, here is what we will learn next. Certainty says: we have solved the ambiguity.

The danger is that many leadership challenges cannot be solved in that way. Ronald Heifetz's distinction between technical and adaptive challenges makes this concrete. Technical problems can be solved with existing expertise. Adaptive challenges are different: the problem itself may be hard to define, the solution is unknown, and, in Heifetz's account, the work can only be done through changes in people's priorities, beliefs, and habits. There is no ready-made answer to apply. There is only progress.

I touched on this in Leading on the Edge of Uncertainty, but the adaptive piece I want to draw out here is narrower. It is the moment when a leader is being asked to declare a winner between two legitimate positions, and the more useful move is to refuse the framing.

Problems and polarities

Some tensions are not problems at all. A problem can be solved and put down; a polarity has to be managed, held in a kind of ongoing balance, because both sides are permanently true. Innovation and efficiency. Autonomy and control. Change and stability. Short-term delivery and long-term renewal. None of these has a winning side, and treating them as though they do is where a lot of the trouble starts. Barry Johnson gave this its name, polarity management, and the distinction has stayed with me ever since.

What I notice in workshops is that organisations rarely treat them that way. They treat them as problems and try to solve them by picking a side. The business over-indexes on growth, then discovers inefficiency and swings hard into cost-cutting. The leadership team over-indexes on autonomy, then sees fragmentation and swings hard into control. The culture over-indexes on harmony, then struggles with accountability and swings hard into challenge. One pole becomes the answer, until its shadow becomes impossible to ignore, and then the organisation overcorrects. The pendulum swing is exhausting, and it gets described as transformation when it is closer to avoidance: we keep solving the wrong shape of problem.

I have watched this particular version play out again and again. A leadership team decides the business has grown flabby and declares a year of discipline: cut, focus, tighten. It works, for a while. Then the good people start leaving, because discipline with no room to breathe is just fear with a spreadsheet, and the same team reconvenes to announce a bold new era of empowerment and trust. Nobody in the room says the obvious thing, which is that they are not fixing the problem, they are swinging back through it, and they will be here again in three years wearing the opposite badge. Each swing feels like a decision. Together they are a way of never deciding at all.

There is a simple move that helps, though it is hard to remember when the room is tense. Whenever two capable people disagree for long enough, assume each is protecting something worth keeping. The person arguing for speed is usually protecting momentum, or competitiveness, or belief. The person arguing for patience is usually protecting quality, or trust, or coherence. Once you see each side as defending something legitimate, the question stops being which person wins and becomes what the system needs to hold.

Negative capability

John Keats had a phrase for this, written in a letter in 1817. He called it negative capability: being "capable of being in uncertainties, Mysteries, doubts, without any irritable reaching after fact and reason." Keats was writing about poetry, but the description fits the leadership work I am trying to point at.

It is the irritable reaching that does the damage, the pull towards premature resolution. In organisational life, and in our own nervous systems, the pressure is to make discomfort go away: to decide, align, and move on. A great deal of organisational behaviour is built for exactly this, smoothing over conflict and reaching alignment before people have really thought, using language that makes unresolved things sound resolved.

Discomfort is often information, though. It may signal that a real tension has surfaced, that people are carrying different truths from different parts of the system, that a strategy has not yet met reality. The capacity to stay with that discomfort, without rushing to false certainty, is closer to what wisdom looks like in practice than any particular answer.

In Why We're Brilliant at How, I wrote about how organisations default to tactics over strategy because the brain finds abstraction expensive. Holding a polarity is a related cost. It demands the same slow, effortful, energy-hungry mode of attention, and it is uncomfortable in much the same way. The pull towards picking a side is rarely a failure of nerve. It is the path of least resistance, and noticing it is most of the work.

The part nobody tells you is hard

All of this is easy to admire from a distance and difficult to do standing in front of people. Holding a tension open has a cost that the frameworks tend to skip over, and it is not intellectual. It is social. When you decline to pick a side, you deny your team the one thing they came in wanting: to know which way you lean.

People follow direction more easily than they follow doubt. A leader who says "we are going this way" gives everyone something to organise around, even when the direction later proves wrong. A leader who says "both of these matter and we are going to hold them in balance" gives them something much harder to act on, and risks looking, to the room, like someone who cannot make up their mind. The tension you are trying to hold on the team's behalf gets read as weakness in you.

I think that is the real reason leaders binary-choose, and it is not stupidity or laziness. It is self-protection. Choosing a pole looks decisive. Holding the tension looks like you do not know, and few things feel more exposing in a senior role than appearing not to know. We reach for the marker instead, draw the line, and take the private relief of having looked certain, whatever it costs later when the shadow of the pole we chose arrives on schedule.

The leaders I have watched do this well have found a way around that, and it is not the one I expected. They do not resolve the tension for the room, and they do not leave the room stranded in it either. What they do is make not-knowing feel survivable. They build enough trust, in themselves and between the people around them, to create a kind of coherence that lets everyone sit in the uncertainty without panic. The message is not "I have the answer." It is closer to "we will work this out together, and I am not frightened that we cannot yet see the end." People can follow that. It turns out you do not need to hand them a direction. You need to make it safe not to have one yet.

Often, once the pressure to decide has passed, it becomes clear there was no choice to make. We are lulled into believing we face a binary, this or that, speed or care, autonomy or control, when the honest answer was "both, and" all along. The choice was manufactured, by the meeting, by the plan, by our own discomfort with holding two things at once. The wise move was never to choose well between them. It was to notice the choice was false.

I want to be careful here, because "both, and" is also the favourite phrase of leaders who cannot bring themselves to decide anything. Held wrongly, it is not wisdom at all. It is a way of dodging a real choice while sounding thoughtful, of keeping everyone onside by committing to nothing, of letting a decision that genuinely needed making rot in the name of nuance. Some binaries are real. You cannot ship the product and keep polishing it forever; at some point the money runs out and the market moves. The skill here is not holding every tension open. It is telling the difference between a false binary, where the two poles need each other and picking one breaks the system, and a real fork, where the two roads genuinely diverge and refusing to choose is just a slower way of choosing badly. The wise leaders I have watched are not the ones who never decide. They are the ones who can feel which kind of moment they are in.

There is a clue to this buried in the word itself. The Latin for wisdom, sapientia, comes from sapere, to taste. Before wisdom meant knowing the answer, it meant discernment, the palate for telling one thing from another, this from that, the false binary from the real fork. Not the reflex to resolve, but the discrimination to know what kind of thing you are holding.

That is what the third voice in the room understood, the one who said "it's both, and" while the rest of us waited for a winner. Not a clever compromise. A refusal of the premise. Wisdom, it seems to me now, is less the ability to find the right answer than the composure to see when the question was wrong, and the nerve to still decide when it was right.
