Background

“Attention is the only thing we have”—this observation becomes particularly meaningful in the current AI era dominated by Transformer architecture. David Bessis proposed a conjecture theory about cognitive inequality in an article published in February 2026, creating an interesting contrast between how mathematicians' brains work and attention mechanisms in artificial neural networks.

The core questions in the article touch upon fundamentals of cognitive science: what exactly happens inside a brain when a person demonstrates extraordinary mathematical talent? Bessis, as a professional mathematician, observed that mathematical progress involves not only mathematics itself, but also metacognition and emotional control. This observation challenges popular genetic determinism assumptions, instead placing focus on trainable cognitive habits.

Key Insights

1. Questionable Structural Basis of Cognitive Inequality

While some people may genetically possess more efficient neural metabolism, allowing their mathematical abilities to be two to ten times greater than ordinary people, genes alone struggle to explain the observed extreme level of inequality. Unlike highly heritable polygenic traits (such as height) that typically follow Gaussian distribution, the distribution of mathematical talent more closely resembles Pareto distribution, which usually stems from sequential extraction processes—“rich get richer” mechanisms where each step builds upon previous results.

2. Special Activation Patterns in Mathematicians' Brains

A 2016 fMRI study by Marie Amalric and Stanislas Dehaene scanned professional mathematicians and non-mathematical specialists with comparable mathematical literacy, finding that professional mathematicians, when evaluating advanced mathematical statements—whether algebraic, analytical, topological, or geometric—activated a reproducible set of bilateral prefrontal, intraparietal, and ventrolateral temporal regions. Crucially, these activations avoided language-related areas; brain activity during mathematical reflection bypassed language-related regions around the central sulcus and temporal regions traditionally involved in general semantic knowledge. Amalric & Dehaene, PNAS 2016

When mathematicians think about mathematics—whether analysis, algebra, geometry, or topology—parietal and lower temporal regions of both hemispheres are activated. By contrast, non-mathematicians facing identical mathematical statements activate language processing regions. This suggests mathematicians unconsciously switch to a special “mathematical mode,” attempting to “see” and “feel” the existence of these abstract structures in a particular way.

3. Enormous Differences in Metacognitive Habits

Many distinguished mathematicians have attempted to clarify one point: their talent is primarily a cognitive attitude. Einstein claimed “I have no special talent, I am only passionately curious”; Descartes insisted at the opening of his Discourse on Method that his mind is no better than ordinary people’s; Grothendieck emphasized “this power is by no means some extraordinary gift.” David Bessis, Mathematica: A Secret World of Intuition and Curiosity

Research shows that metacognitive knowledge and metacognitive monitoring are directly positively correlated with high school students' mathematical modeling skills, and the critical thinking dimension of computational thinking mediates the relationship between metacognition and mathematical modeling skills; sufficient metacognition can improve students' critical thinking in computational thinking and enhance mathematical modeling abilities.

4. Secondary Stimuli and Synaptic Connectome

Bessis proposed a critical hypothesis: there must necessarily be physical differences between the brains of exceptionally intelligent people and ordinary people, otherwise where do cognitive differences come from? His conjecture theory posits that the cognitive differences measured at any given moment for an individual are primarily explained by differences in their synaptic connectome.

This framework views the brain as a learning device rather than a computational device. Our synaptic connectome responds to reconstruction not only from primary stimuli (raw sensory signals from the world) but also from secondary stimuli—the continuous stream of mental imagery we generate. When you read a book, the primary stimulus is the ink on the page, but if certain books make you smarter, it’s not only because of the ink itself but also because of the related secondary stimuli triggered by the book and sustained for minutes, hours, days, years—those fleeting thoughts and mental images.

5. Trainability of Attention Control

Both intelligence and metacognitive skills are considered important predictors of mathematical performance, but the role of metacognitive skills in mathematics appears to change early in secondary education, and according to monotonic development hypothesis, metacognitive skills improve with age independent of intelligence development. Veenman Research

Metacognitive instruction produced substantial positive effects on metacognitive skills (effect size ES = 1.18, p < 0.001), with students in the treatment group showing significantly greater improvements in metacognitive skills compared to the control group. This indicates that through deliberate practice, more effective attention allocation and cognitive monitoring strategies can be cultivated.

6. The Algebraic Nature of Raven’s Matrix Test

Bessis offers unique insights into IQ testing. Raven’s Progressive Matrices, as one of the most g-loaded IQ tests, actually exudes a strong undergraduate algebra flavor—all about 3-cycles and permutation matrices. He subjectively found that by projecting mathematical structure onto pictures, he could gain intuitive perception of three overlaid permutation matrices (one for background geometric shapes, one for foreground rectangles' color, one for foreground rectangles' angles), and this intuitive perception greatly reduces demands on “working memory.”

More importantly, Raven’s Progressive Matrices show an increase rate of 7 IQ points per decade, more than double the rate of the Flynn effect observed on multifactor intelligence tests like WAIS and SB. This rapid growth may be explained by the increasing permeation of tabular structures in the cognitive environment—our numerical sense has undergone substantial evolution over the past millennium.

7. The Role of Cognitive Inhibition and Confidence

Cognitive inhibition is adaptive protection against learning from unreliable mental imagery; unlocking creative thinking and mastery requires overcoming it, partly regulated by social feedback, resulting in cognitively self-reinforcing stratification that solidifies with age.

Renowned mathematician Bill Thurston observed: when someone in mid-career proves a theorem widely recognized as important, their status in the community—their ranking—immediately and significantly rises; at this point they typically become more productive, becoming centers of thought and sources of theorems. This illustrates that the elevation of confidence, becoming central in the thought network, and (most importantly) discovery of new ways of thinking, act together.

8. Training Mathematical Intuition

Bessis advocates consciously training one’s mathematical intuition to work more effectively, a process he calls “System 3,” as a continuation of psychologist Daniel Kahneman’s famous distinction between System 1 (automatic, unconscious ability) and System 2 (conscious methodological reasoning). SIAM Review

This training is not about learning information but expanding the range of structures one can conceptualize. Just as blind boy Ben Underwood learned to “see” through tongue clicks and echolocation, mathematicians through continuous metacognitive practice retrain their brains to intuitively perceive abstract structures.

Open Questions

1. Can the neural mechanism of secondary stimuli be directly measured? If cognitive development is primarily mediated by secondary stimuli, could one design longitudinal neuroimaging studies tracking the evolution of brain activation patterns in students during key stages of mathematical learning (such as the two-year intensive training of French prépa)? Bessis predicts that individual students' progress trajectories will be significantly correlated with strengthening and/or more frequent use of the Amalric-Dehaene “mathematical brain” activation patterns.

2. Can metacognitive training cross the “genius threshold”? Bessis acknowledges only a “20% full cup”—critical aspects of psychological habits and metacognitive methods have solidified before children acquire language ability. But if cognitive stratification is primarily driven by trainable attention habits rather than genetic ceilings, do there exist yet-undiscovered teaching interventions that can systematically push more people toward the extreme tail of the cognitive distribution? Or does the randomness and path dependency of early neural development set insurmountable limits on achievable cognitive restructuring?
