Why Insight Is Not Change

A portfolio manager once walked me through his own trading data. It showed, in numbers, that he sold his winners too early and held his losers too long.

He knew the name for the pattern. He could explain the mechanism more precisely than I could, including why it had felt reasonable in the moment, every time.

What stayed with me wasn't the error. It was how completely he understood it, and how little that understanding changed the following quarter.

That gap, between what someone knows and what they actually do, is one of the most common things I see in my coaching work. It's rarely just a knowledge problem.

Understanding is the cheapest part

You already know your pattern. You've named it in a 360, at an offsite, or in a conversation with someone you trust, and you can probably describe it more precisely than the person coaching you. And you did it again on Tuesday.

Research on the intention–behaviour gap is blunter about this than most coaching advice. Across 47 experiments that deliberately changed people's intentions, a medium-to-large shift in intention produced only a small-to-medium shift in behaviour. Intention is already a step beyond understanding. Understanding sits further back still.

Sometimes insight is enough. When the behaviour was an unexamined habit, naming it can loosen or even end it. That happens, and it's why the advice to build awareness persists.

The rest of the time, something else is maintaining the pattern.

The head agrees. The body doesn't.

That phrase is coaching shorthand, not literal neuroscience. What it points at is that intellectual understanding and learned response don't change at the same speed.

Lisa Feldman Barrett's work sits within a broader predictive-processing account of the brain. In this view, the brain draws on past experience to anticipate what's likely to happen next, and updates its expectations when incoming information doesn't match. Those expectations aren't fixed. But neither are they rewritten because you've reached a new intellectual conclusion.

You may know that a few seconds of silence in a meeting won't make you look weak, and still feel the urge to fill it.

You may know your team is capable, and still feel tension when you hand over something that matters.

You may know you don't need every answer, and still feel exposed when asked something you can't immediately solve.

That's the gap. Not two organs disagreeing – one conscious conclusion, and a set of responses learned over twenty years that hasn't been given any reason to revise.

The behaviour was doing a job

Here's the part leadership advice skips most often. The behaviour you want to leave behind may also have been protecting something.

Kegan and Lahey's Immunity to Change framework describes hidden competing commitments: you can genuinely want one outcome while another part of you stays committed to avoiding a perceived risk. Interrupting may protect you from looking slow. Over-preparing may protect you from being caught without an answer. Doing the work yourself may protect you from discovering that your team can't yet deliver to the standard you need.

So stopping isn't only dropping a habit. It's removing cover, and your system reads that as risk.

There's a systemic dimension too. Teams adapt around leadership patterns. If you routinely take work back, people stop taking full ownership. If you always speak first, others wait for your view before offering theirs. Eventually it surfaces somewhere visible: a succession plan with no obvious candidate, a function that stalls whenever you're away, a board that has started asking who else could run this. By then the pattern no longer belongs only to you.

Acceptance is not resignation

The word sounds soft in a leadership context, and it isn't meant softly here. Not resignation, and not this is just who I am. What's meant is the willingness to see what's actually happening without immediately defending it, judging it, or forcing it away.

What has this behaviour been doing for me? What did it help me achieve? What did it protect me from? And what is it costing me now?

Both sides matter. Many of the behaviours that trouble people later in their careers were once intelligent responses to the environment they were working in. The founder who now struggles to delegate may have built the business precisely because she noticed everything. The fund manager who overchecks every decision may have learned, painfully, that small details matter.

These patterns didn't appear from nowhere. Often they worked, sometimes exceptionally well, and occasionally they're part of why the person succeeded at all. The difficulty comes when the context changes and the response doesn't.

That's why acceptance matters. Not because the behaviour should stay, but because fighting it stops you understanding why it's still there.

You don't have to like the pattern. It helps to give it credit for what it once helped you achieve or avoid.

What this changes on Monday

Herminia Ibarra puts it more sharply than I would: at real transition points, there's nothing you can introspect your way out of, and you act your way into new thinking rather than the reverse. That isn't an argument against looking inward. It's an argument about sequence.

What comes next will feel like a detour if you were promoted for thinking. Do it anyway.

Start with the honest sentence. Doing it myself protects me from finding out whether my team is as good as I hope. Say it aloud and notice your reaction. Tension, resistance, embarrassment or urgency are useful data. They don't prove what the underlying belief is, but they show you where to look.

Then test the expectation, not with a resolution but with a small experiment. One meeting where you don't speak first. One handover you don't immediately check. One difficult conversation you don't script. Small enough to attempt, meaningful enough to produce new evidence. Then repeat it.

That's the order I work in: notice, accept, then test. Not because change follows fixed stages – systematic reviews have found little evidence that stage-based models outperform other approaches, and people skip steps constantly. Rather because moving straight from insight to action leaves the protective logic of the old behaviour untouched.

Worth sitting with

1. What behaviour do you understand very well and still repeat?

2. What has it protected you from, and what did it earn you earlier in your career?

3. When you say the honest sentence aloud, what do you notice?

4. What small experiment would give you evidence rather than another explanation?

In short

Insight is change that hasn't reached the body yet. You can understand a pattern, know where it came from, genuinely intend to behave differently, and still repeat it – because agreement isn't experience, and because the behaviour was probably protecting something. Understanding helps you see the pattern. Acceptance helps you stop fighting it. Experience gives you something new to learn from.

Where this goes next

Reading about this is one thing. Doing it in a real role, with real stakes and people watching, is another.

Most of my work is with senior leaders, founders and investors in finance and tech, often at the point where something that contributed to their success no longer serves the role, the business, or the person they're becoming.

On acceptance: the evidence from Acceptance and Commitment Therapy concerns a multi-component intervention, so acceptance can't be isolated as the active ingredient. The role given to it here is practitioner observation, not proof that acceptance alone causes change.
