Summary: New research reveals that the brain leaves subtle, measurable traces of creative insight minutes before an “aha!” moment. By filming mathematicians as they worked through difficult problems, researchers discovered that behavior became less predictable just prior to a breakthrough.
Applying tools from information theory, the research team showed that unpredictability in moment-to-moment actions increased as novel cognitive connections formed. These results provide a fresh empirical window into the dynamics of creativity and suggest the possibility of anticipating insight across a range of disciplines.
Key Facts
- Creativity Traces: Moments of insight are preceded by measurable increases in behavioral unpredictability.
- Cross-Disciplinary Potential: The approach can be applied beyond mathematics to fields such as science, design, and the arts where thinking evolves through observable steps.
- Interdisciplinary Advance: The study blends ideas from physics, ecology, and psychology with information-theoretic methods to map creativity’s micro-dynamics.

Insight that feels instantaneous may actually have a detectable buildup.
“Aha!” moments are often described as sudden and unpredictable, but this study shows they can be preceded by subtle, measurable changes in behavior. The researchers developed a method to detect those changes minutes before participants verbalized an insight, opening a new avenue for studying how breakthroughs emerge in real time.
The study appears in the Proceedings of the National Academy of Sciences (PNAS). The lead author is Shadab Tabatabaeian, Ph.D. in Cognitive and Information Sciences from the University of California, Merced. Tyler Marghetis, assistant professor of Cognitive and Information Sciences at UC Merced, is the senior author. Co-authors include Artemisia O’bi (Indiana University) and David Landy (Netflix and Indiana University).
To investigate the approach of insight, the team video-recorded six Ph.D.-level mathematicians as they worked on problems drawn from the William Lowell Putnam Mathematical Competition. Recording took place in familiar settings—offices and seminar rooms—with participants using blackboards and chalk as they reasoned through proofs and ideas.
From these recordings the researchers extracted a dense record of behavior, documenting more than 4,600 discrete interactions with the blackboard—writing, pointing, erasing, and shifts in attention. Analyzing these moment-to-moment actions with information-theoretic measures, they observed a consistent pattern: in the minutes before a mathematician exclaimed “aha!” or “I see it!”, their sequence of actions became noticeably less predictable.
That rise in unpredictability was quantified using an information-theoretic index designed to capture how surprising or novel a sequence of behaviors is relative to prior patterns. The more the pattern diverged from routine transitions between ideas or actions, the stronger the signal that an insight was imminent. The authors liken this to “critical fluctuations” observed before transitions in physical and ecological systems—periods when a system explores new configurations prior to a shift.
“This discovery was only possible because we combined perspectives from very different fields,” said Marghetis. “We used concepts from ecology and physics, applied tools from information theory, and built on decades of psychological research into creativity. The result highlights dynamics that aren’t confined to any single discipline.”
Although the experiment focused on expert mathematicians, the researchers note that the method should generalize to other domains where thinking proceeds through visible, discrete steps: a chemist sketching molecular structures, a designer rearranging prototypes, or an artist experimenting with form and composition. In each case, traces of emergent novelty may appear in behavior before a person reports an insight.
The authors suggest this information-theoretic approach could help scientists better understand the micro-dynamics of creativity and, potentially, develop ways to anticipate breakthroughs as they arise. More broadly, the findings emphasize that sudden insights can be framed as transitions within complex systems—transitions that leave measurable foreshadowing in observable activity.

An information-theoretic foreshadowing of mathematicians’ sudden insights by Shadab Tabatabaeian et al., Proceedings of the National Academy of Sciences (PNAS). DOI: 10.1073/pnas.2502791122
Abstract (summary)
The sudden “eureka” insights that propel science and mathematics retain an air of mystery. These abrupt, unexpected events resemble critical transitions in complex systems. Zooming in on mathematicians working on proofs in their own departments, the authors show that sudden insights are anticipated by a system-agnostic, information-theoretic early warning signal. Dense behavioral recordings reveal that blackboard interactions—writing, gesturing, erasing—grow increasingly unpredictable before an insight, analogous to the critical fluctuations that precede transitions in physical and ecological systems. The paper explores when this early warning applies to systems with discrete, symbolic dynamics and argues that explaining innovators’ sudden insights requires attention to the local, distributed systems of their intellectual activity.
