What If the Most Underrated Brain in the Room Belongs to a Gen X?

👋 Hej,

Let me tell you about a generation that nobody is writing think pieces about anymore.

Not Boomers, there are entire industries built on managing their exit. Not Millennials, the world spent two decades trying to understand them. Not Gen Z, every HR conference has a panel on them right now.

I’m talking about Gen X.

Born roughly between 1965 and 1980. Old enough to remember a world without internet. Young enough to have built their careers inside it. The generation that grew up being told they were cynical, pragmatic, and quietly self-reliant, and then got on with it without making much noise.

They are now between 45 and 60. They are in the middle of the most neurologically powerful decade of their professional lives.

And most of them have no idea.

Let me start with the science, because this is where most people get it completely wrong.

The brain of a Gen X professional is not declining. It is completing.

Myelination (the protective sheath around neural connections) continues strengthening well into the fifties. The result: brain regions communicate faster, more fluidly, more in parallel. Things that required conscious effort at 30 become automatic at 50. Not because you are coasting. Because your brain has built the infrastructure to process them without burning energy.

The prefrontal cortex (the seat of complex judgment, long-range thinking, and the ability to hold contradictory truths simultaneously without panicking) reaches a functional maturity in this decade that it simply did not have at 30. The Gen X professional who says “I don’t know yet, let me think” is not being indecisive. They are using a more sophisticated cognitive tool than the person who answers in five seconds.

And then there is integrative thinking (the ability to see the pattern beneath the pattern). To notice that the new strategy looks a lot like the one that failed in 2008. To understand that the “urgent” problem is not actually the real problem. To hold the human angle, the systemic angle, and the historical angle in the same thought simultaneously.

Researchers call this a superpower. Most organisations call it resistance to change.

They are wrong. And it is costing them.

Here is what I hear when I talk to Gen X professionals — and I have been collecting these conversations for my book.

“I stopped raising my hand in meetings. Not because I don’t see the risks anymore. Because I learned that nobody wants to hear about risks before they materialise.”

“They call it lack of agility. But I’m not resisting change — I’m evaluating it. I’ve seen too many badly prepared transformations to applaud everything that moves.”

“I’m not against new. I’m against new for the sake of new.”

These are not people refusing to change. These are people who have changed enough times to know the difference between a necessary pivot and well-dressed agitation.

But here is the brutal truth about what happens to a brain that receives the same signal “you are too slow, too expensive, too analogue” for long enough.

It believes it.

Psychologists call this stereotype threat: the mechanism by which you perform below your actual capabilities not because they have diminished, but because you have internalised the gaze of those who believe they have.

You don’t lose your capabilities. You lose your belief in your capabilities.

That is not the same thing. But the result is identical.

The Gen X professional goes quiet in meetings where they should speak. Hesitates where they should act. Starts to wonder whether what they see is still worth saying.

That silence is not wisdom.

That silence is an organisation losing its best early-warning system.

Gen X grew up in analogue and learned to think in digital. They did not have the luxury of a native operating system — they had to translate, adapt, and rebuild their mental models multiple times before most of today’s workforce entered the room.

That experience, of living through discontinuity and coming out the other side, is not nostalgia. It is a blueprint.

In a world of AI disruption, geopolitical instability, and organisational complexity that no algorithm can fully navigate, the cognitive profile of the Gen X professional is precisely what is needed:

→ Pattern recognition built across decades of real crises, not simulated ones

→ Discernment — the ability to distinguish urgent from important, signal from noise

→ Integrative thinking — seeing what the optimistic and the pessimistic both miss

→ Designed intentionality — the Gen X habit of building deliberately, not reactively, because nobody was going to do it for them

That last one matters most. Gen X did not have helicopter parents or participation trophies. They were handed autonomy early — sometimes too early — and learned to design their own path on purpose. That muscle, built in adversity, is exactly what organisations need people to do right now.

The problem is not that Gen X lacks relevance.

The problem is that Gen X stopped claiming it.

Périmé? — in English, Expired? — is built on exactly this argument. The science of why the 50+ professional brain is not a liability but a premium asset, and the behavioral framework for making that case impossible to ignore.

The French version is available now. The English version: Expired? launches in September 2026.

Think of one moment in the last month where you had a perspective, a risk, or an insight — and chose not to say it. Ask yourself honestly: was that discretion? Or was that stereotype threat doing its job? Name it. Then decide whether it deserved a voice.
