Sometimes when I’m stuck on a project, I realize I’m looping the same thoughts. That’s usually my signal to step away, because instead of solving the problem, I’m worsening it.

Researchers at Nature just introduced Centaur, a foundation model trained to do exactly that:

Simulate human reasoning across thousands of psychology experiments.

And it doesn’t simply predict outcomes.

It predicts how people will think, where they will mess up, and why they will change their minds.

That matters for anyone building products.

It means you could test ideas against a cognitive model before real users ever touch them.

To see how a customer might misunderstand a prompt, skip a step, or get stuck in a problem-solving loop.

Think of it as a behavioral mirror: showing how your product feels to the brain, not only to the metrics.

Soon, designing a great user experience will mean co-designing with an AI that already “thinks human.”
