Is AI Killing Our Creative Diversity? When All of Humanity Shares One "Smart Brain"
Imagine walking into a paint store on a sunny afternoon, planning to buy some colors to paint the ideas in your head.
In the past, everyone who entered chose different colors. Some loved deep indigo, some preferred wild lemon yellow, and some would even mix their own strange, unnameable shade of gray. Though the quality of the paintings varied, placing them all side by side revealed a colorful world full of surprises.
Now, a super sales assistant has moved into this store — AI.
It greets everyone enthusiastically: "Dear, based on my big-data analysis, these pigments are currently the most popular and the easiest to make good-looking paintings with. I suggest you use these three." So everyone walks out holding the exact same palette.
The result: everyone's paintings have indeed become "better," but spread all the paintings out in a plaza and you'll discover in horror — my God, why has everyone painted exactly the same thing?
This is the uncomfortable truth revealed by a major paper published on arXiv on May 7, 2026 — "Ex Ante Evaluation of AI-Induced Idea Diversity Collapse": AI is causing a "Diversity Collapse" in global human creativity.
What Is "Diversity Collapse"?
The paper's authors, Nafis Saami Azad and Raiyan Abdul Baten, propose a sharp distinction: individual utility vs. population-level crowding.
- Individual Utility: This is AI's strength. It helps you write smoother code, more moving love letters, more professional status reports. For you personally, AI genuinely makes you stronger.
- Population-level Crowding: This is the overlooked side effect. When millions of people use the same model (say, GPT-4 or Claude) to seek inspiration, AI tends to steer everyone toward the highest-probability, most "safe" direction.
The Hard Data in the Paper
To quantify this "disappearance of creativity," the authors developed a set of mathematical tools, including an excess crowding coefficient (\(\Delta\)) and a human-relative diversity ratio (\(\rho\)).
They had AI and humans complete creative tasks such as writing short stories and brainstorming marketing slogans, and found:
While individual AI-generated works are high quality, the similarity and overlap between multiple AI outputs is extremely high.
Mathematical tests showed that the three most advanced AI models all have diversity ratios (\(\rho\)) significantly below 1. This means: if you rely on AI for creative work, the total amount of unique ideas humanity produces shrinks dramatically compared to a world without AI.
What Should We Do?
Feynman once said: "I would rather have questions that can't be answered than answers that can't be questioned."
If we abandon humanity's most precious, somewhat chaotic and error-prone originality in pursuit of a little bit of "safe good-looking," then the pond of human inspiration may slowly dry up into stagnant water.
The paper also offers a prescription for AI developers:
AI's optimization objective should not just be "useful" — it should "encourage divergence."
The AI of the future should not be the shopping guide telling you the "trending colors," but an inspiration partner that notices "everyone has been painting in blue lately — shall I recommend some purple instead?"
To summarize:
Tools are meant to extend our hands and feet, not to homogenize our brains.
The next time you click the "generate inspiration" button, remind yourself: AI's most perfect answer may also be the most mediocre consensus. Sometimes, deliberately choosing the "strange color" AI didn't recommend is your last act of stubbornness — the way you preserve human dignity in the AI era.
Don't let intelligence kill diversity. Don't let our world, with AI's help, become more and more boring.
