Your Brain on AI: The Shocking Decline in Creative Thinking (2025)

Our ability to solve complex problems without AI has plummeted 30% in just five years.

That's not just a statistic – it's the sound of your brain cells surrendering.

We are announcing a new series we are calling –  Creative Thinking in the AI Age – on strengthening your uniquely human creativity while using AI as a partner, not a replacement.

Today, we will explore how AI dependency is creating a pandemic of reduced creative thinking and why this matters more than you might realize.

Look around. We've all seen it – colleagues endlessly prompting AI for answers, friends asking their devices the same questions with slight variations, and kids who reach for ChatGPT before trying to solve a problem themselves. It's happening everywhere. We're witnessing a slow, subtle decline in our collective ability to think deeply, creatively, and independently.

This cognitive shift is measurable. Recent research from the University of Toronto found that college students today show a 42% decrease in divergent thinking scores – our ability to generate multiple solutions to problems – compared to students just five years ago. The difference? The widespread adoption of AI tools.

This isn't just happening in schools. Creative professionals show similar patterns. Marketing agencies report that junior staff increasingly struggle to generate original campaign concepts without AI prompting. Engineering teams face growing difficulties when asked to ideate without computational assistance.

But this isn't a rant against technology. AI is here to stay, and it offers tremendous benefits. The real issue is how our relationship with these tools is reshaping our cognitive capabilities.

Remember when calculators became widespread? Many feared we'd lose our ability to do basic math. They weren't entirely wrong, but we adapted. The difference now is that AI doesn't just handle calculations – it's beginning to think for us.

This surrender of our thinking faculties brings us to an uncomfortable but powerful concept from theologian Dietrich Bonhoeffer. Writing from a Nazi prison in 1943, he described a phenomenon he called “stupidity” – not as a lack of intelligence, but as a social contagion where independent thinking is surrendered to external forces.

Bonhoeffer wasn't talking about AI, obviously. But his insight that humans will easily surrender their thinking faculties to external authorities is profoundly relevant today. We're increasingly outsourcing our cognitive heavy lifting to algorithms, and our brains are adapting accordingly.

Let me show you what I mean with a quick demonstration. Take 30 seconds right now to list five uncommon uses for a paperclip. No use of AI. I'll wait.

How'd you do? If you struggled, you're not alone. In tests conducted before widespread AI adoption, the average person could generate 8-12 unique ideas. Today, that number has dropped to 3-5.

This decline in creative thinking ability is not only disappointing – it has neurological implications. When we regularly outsource thinking, the neural pathways associated with creative problem-solving literally weaken. It's cognitive atrophy – it's like any other muscle, use it or lose it. And with AI, you aren’t using it.

The consequences are more serious than you might think. Here's what's happening: AI is great at finding the optimal solution within defined boundaries using “convergent thinking.” Give AI the parameters of a problem, and it'll efficiently identify the best answers within a set of constraints.

But what humans uniquely excel at is “divergent thinking” – our ability to break through boundaries, reimagine the entire problem, and make unexpected connections between seemingly unrelated ideas. This is where breakthroughs happen. Recent research from the University of Bergen shows that while AI can generate more ideas than the average person, the most creative human solutions significantly outperform AI in originality and innovation.

Here's the paradox: the more we rely on AI, the more we get trapped in what psychologists call “AI-reinforced conventional thinking.” Let me demonstrate.

In a creative thinking workshop I ran not long ago, I asked participants to design a new coffee cup. Most drew variants of the same cylindrical container with a handle. When asked why, they couldn't explain – they'd simply imposed an invisible constraint.

But when one participant suggested a coffee cup that could be worn as a ring, the floodgates opened. Suddenly, people were designing coffee cups that doubled as plant holders, that changed color with temperature, and that folded flat for storage.

This mental breakthrough reveals what neuroscientists call the “first insight phenomenon” – that moment when one disruptive idea shatters the invisible walls of conventional thinking and unleashes a cascade of creative possibilities. We're not just limited by what we know, but by what we don't realize we're assuming.

When we look at history's greatest innovations, this ability to think beyond self-imposed constraints becomes even more critical. The transistor. Penicillin. The theory of relativity. The internet itself. None of these came from incremental optimization.

They required creative leaps that defied conventional thinking – precisely the kind of thinking we're at risk of losing in our growing dependency on AI.

But here's the good news – research from cognitive neuroscience and psychology confirms what I've seen firsthand: our thinking skills can be systematically improved. We can rebuild and strengthen these creative pathways with the right techniques.

This is where the concept of neuroplasticity becomes crucial. Like muscles, cognitive abilities respond to consistent, targeted exercise. And just as we've developed scientific approaches to physical fitness, we now have evidence-based methods for improving creative thinking skills.

The research findings are encouraging: In just minutes a day of targeted practice, people show measurable improvements in creative output. And unlike many skills that decline with age, creative thinking can actually improve throughout our lives – if we nurture it.

We stand at a crossroads. One path – cognitive surrender – is seductively easy. The other path requires effort but leads to something extraordinary: a partnership where AI handles the routine while we cultivate our uniquely human capacity to imagine what has never existed before.

Here's what gives me tremendous hope: our brains remain remarkably adaptable throughout our entire lives.

In the next episode, we'll dive into this revolutionary science and learn how to rewire our thinking for an AI-augmented world without losing what makes us human.
