The evolution of self-control.
Open accessAbstract
Significance: Although scientists have identified surprising cognitive flexibility in animals and potentially unique features of human psychology, we know less about the selective forces that favor cognitive evolution, or the proximate biological mechanisms underlying this process. We tested 36 species in two problem-solving tasks measuring self-control and evaluated the leading hypotheses regarding how and why cognition evolves. Across species, differences in absolute (not relative) brain volume best predicted performance on these tasks. Within primates, dietary breadth also predicted cognitive performance, whereas social group size did not. These results suggest that increases in absolute brain size provided the biological foundation for evolutionary increases in self-control, and implicate species differences in feeding ecology as a potential selective pressure favoring these skills.

TL;DR
This study experimentally compared self-control across 567 individuals from 36 mammal and bird species using two problem-solving tasks and phylogenetic comparative methods. It found that absolute brain volume, not relative brain volume, best predicted performance, and that within primates dietary breadth—but not social group size—was strongly associated with self-control.
Key findings
- Across species, absolute brain volume (endocranial volume, ECV) was a robust predictor of self-control, explaining substantial variance on the cylinder task and composite score (r² = 0.43–0.60); residual brain volume explained only 3% of variance in composite scores.
- Within primates, absolute brain volume was the best predictor (r² = 0.55–0.68), and dietary breadth also covaried strongly with self-control (r² = 0.68); a multiple regression including both ECV and dietary breadth explained 82% of variance in primate composite scores.
- Social group size (population and foraging group size) and percent fruit in diet were not significant predictors of primate self-control, whereas observational measures such as social learning, extractive foraging, tool use, tactical deception, and g_s covaried positively with experimental scores.
- Performance on the two tasks was strongly correlated across species (r = 0.53, n = 23, P < 0.01), and scores from multiple populations of the same species were highly correlated (cylinder: r = 0.95, n = 5, P = 0.01; A-not-B: r = 0.87, n = 6, P = 0.03).
Methods
- The study tested 567 individuals representing 36 species on two self-control tasks: the A-not-B task (27 species, n = 344) and the cylinder task (32 species, n = 439), using standardized pretest criteria and species-level mean performance.
- Phylogenetic generalized least squares (PGLS) was used to test associations between cognitive performance and neuroanatomical predictors (absolute ECV, residual brain volume, encephalization quotient) and socioecological predictors (group size, frugivory, dietary breadth), accounting for phylogenetic nonindependence.
- For primates, the authors also fit a multiple regression with absolute ECV and dietary breadth as predictors of composite cognitive scores, and reconstructed ancestral states along the primate phylogeny.
Limitations
- The paper states that analyses were restricted to whole-brain volume measures because comparative data on finer neuroanatomical substrates (e.g., neuron counts, regional volumes, functional connectivity) were limited.
- The paper cautions that single-task species data must be interpreted cautiously, citing the Asian elephant’s A-not-B performance, and notes that task features may be more appropriate for some species than others.
- The paper states that ecological analyses focused on primates because they were best represented and had systematically compiled ecological data; it also notes that more nuanced social/ecological measures may be needed to detect relationships. Evident from the text: the design is correlational, taxonomic sampling is uneven across groups, and the composite score was available for only 23 species.

In the paper
“In humans, self-control has been linked to health, economic, social, and academic achievement, and is known to be heritable (170-172).”

In the paper
“For example, the best performing species in our sample were predominantly anthropoid primates, species that have evolved unique prefrontal areas that are thought to provide a cognitive advantage in foraging decisions that rely on executive function (176-178).”
§ The evolution of self-control > Discussion
What the sources say
hedgedconditional- Asserted: passes — The authors put it forward as true.
- Checkable: passes — It can be checked against evidence.
- Load-bearing: fails — The paper’s conclusions may not depend on it.
- Based: passes — The paper gives a reason why it holds.
Probably not a substantial claim. The paper’s conclusions may not depend on it.
The paper relies on this without support.
The two problem-solving tasks validly measure self-control across species.
“We experimentally evaluated these major evolutionary explanations by quantitatively comparing the cognitive performance of 567 individuals representing 36 species on two problem-solving tasks measuring self-control.”
The paper relies on this without support.
The composite score averaging performance across tasks is a valid broader index of self-control.
“Because the two tasks assessed complementary but not identical abilities, the composite score serves as a broader index of self-control across tasks.”
Claims other papers make about this one
Each is checked against this paper’s own text: does it say what the citing paper says it does?
The cited source says what the claim attributes to it.
In the citing paper
“Absolute brain size is often a reasonable predictor of specific cognitive abilities in studies that did not use the measure based on cognitive equivalence [Benson-Amran et al., 2013;MacLean et al., 2014;Horschler et al., 2019].”
From A Farewell to the Encephalization Quotient: A New Brain Size Measure for Comparative Primate Cognition (2021) · cites this paper as MacLean et al., 2014
In the citing paper
“In primates, absolute brain size predicts neuron number and is strongly correlated with the ability to inhibit prepotent responses (MacLean et al., 2014).”

Self-check
Percentages, sums and reported differences re-computed from the paper’s own numbers.
Each contradiction between two passages listed here was confirmed by an independent check.
Rated major: it would touch a result — a value a result rests on, reported and recomputed p-values on opposite sides of the significance level, two passages that conflict with no sign which is right, or a cited work retracted before this paper was published.
In the paper
§ The evolution of self-control > Discussion
“even the most predictive neuroanatomical measures failed to account for more than 30% of cognitive variance across species in this study.”
§ The evolution of self-control > Methods
“| | Absolute brain volume | Composite | 5.67 | 21 | <0.01 | 0.60 | 0.00 |”
Rated minor: it would not touch a result — a value no result rests on, a p-value that stays on the same side of the significance level, or a conflict that is clerical, resolved elsewhere in the paper, or outside its own findings.
In the paper
§ The evolution of self-control > Methods
“In both tasks and in the composite measure, ECV was a significant predictor of self-control.”
§ The evolution of self-control > Methods
“| | Absolute brain volume | A-not-B | 1.03 | 25 | 0.16 | 0.04 | 0.69 |”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
