The Flynn Effect: Why Progress Isn’t Automatic (And What That Means for You)

In the 1980s, a quiet discovery started rippling through the scientific world.
James Flynn, a New Zealand philosopher and political scientist was buried in mountains of IQ data. He wasn’t searching for headlines. But something odd kept showing up.
IQ scores weren’t holding steady. They were rising. Fast. And not just in one country, but across nearly every developed nation on Earth. It didn’t make sense. How could entire populations become “smarter” in just a generation? And yet, the numbers didn’t lie.
People weren’t just learning more facts, they were thinking differently. More abstractly. More flexibly. More systematically. This strange, sustained trend became known as The Flynn Effect.
For nearly a century, it seemed like humanity was leveling up. But then… the curve started to flatten. And in some places, it began to drop.
When the World Builds Smarter Minds (And When It Doesn't)
The Flynn Effect wasn’t magic. It was momentum. As the 20th century advanced, so did our environments. Nutrition improved. Schools focused more on abstract reasoning. Cities grew. Jobs became more cognitively demanding. Culture began to reward symbolic thinking over survival skills. Flynn’s insight was simple but profound:
Intelligence isn’t fixed. It’s shaped by the challenges we face, the tools we use, and the questions we’re asked to answer.
In other words: change the environment, and you change the mind.
But here’s the twist. In recent decades, especially in wealthy, well-educated countries IQ scores have started to decline. The very progress we once rode… seems to be stalling. A dramatic Norwegian study tracking decades of data found IQs dropping ~7 points per generation since 1975. Why?
Because we’ve stopped building environments that stretch our thinking. We’ve optimized for speed, convenience, and dopamine not for depth, reflection, and focus.
The Hidden Cost of Easy
Swipe. Tap. Scroll. Click.
Modern life is frictionless by design. And we’re paying for it in cognitive strength. Our attention spans are shorter. Our tolerance for confusion is lower. Our ability to sit with complexity, to wrestle with ambiguity, to think slowly and rigorously? Fading.
Flynn didn’t just uncover a trend. He gave us a warning:
What isn’t deliberately strengthened will eventually weaken.
What This Means for Your Growth (And Why It’s More Urgent Than Ever)
Progress isn’t automatic. Whether you’re building a company, a career, or just trying to get better at something, you can’t coast. You grow by design, not by default.
In the age of AI, this truth becomes even sharper. A team that stops tackling hard problems, stops learning deeply, and stops seeking real feedback? Stagnates.
An entrepreneur who outsources all their thinking to tools even powerful ones like AI may become more efficient… but not more capable. The paradox: AI excels at answers but cannot ask better questions, that muscle remains human. You don’t get stronger by lifting lighter weights.IQ
The habits you build, the problems you chase, the friction you choose these are the engines of your growth.
A generation’s intelligence, a company’s resilience, a leader’s creativity, it doesn’t preserve itself. It’s cultivated. Or it withers.
The Progress Principle: Why Mastery Makes Hard Things Enjoyable
Richard Feynman, one of the greatest physicists of the last century, once said:
“The harsh reality is that if you’re not good at something, it’s hard to enjoy it.”
There’s a myth floating around the business world: that you can build something amazing by “just doing what you love.” But real work the kind that creates value, legacy, or freedom requires mastery. And mastery starts with friction. You’ve probably heard the phrase: “Starving artists can’t sell their work.” What most people miss is why. It’s not a lack of passion. It’s a lack of skill.
Great entrepreneurs become great by getting good at what others avoid: sales, systems, strategy, storytelling. And something strange happens when you do: What once felt tedious starts to feel rewarding. Even fun. Call it the Progress Principle:
Pleasure doesn’t come from finishing hard things, it comes from getting better at doing them.
Shakespeare put it best: “Things won are done; joy’s soul lies in the doing.”
The more you grow, the more you love the climb.
Final Question: Is Your Communication Evolving or Stagnating?
Like intelligence, communication doesn’t just improve on its own. It’s not automatic.
It depends on the space you create for it: Clarity over speed. Substance over noise. Curiosity over certainty. The Flynn Effect showed us something powerful: We can raise the bar, individually and collectively, if we build the right conditions. But if we stop building? Progress reverses.
So ask yourself: Are you designing your environment for growth? Or defaulting to one that slowly dulls your edge?
Progress isn’t a guarantee. But it is possible if you build for it.
"The Flynn Effect reversal isn’t fate. It’s feedback. Your cognitive environment is a choice – and the most radical act of leadership today."
