Network structure explains intellectual discourse across human history Open
The production of knowledge is a collective endeavor. Scientific discovery, for instance, reflects not only the insights of individual scientists but also interactions among scientists. This is often taken to reflect social influences on c…

An information-theoretic foreshadowing of mathematicians’ sudden insights Open
The “eureka” insights that drive progress in science and mathematics remain shrouded in mystery. Sudden, unexpected, appearing like “flashes of lightning”, these insights have the hallmarks of critical transitions in complex systems. Here,…

The network science of philosophy Open
Philosophy is one of the oldest forms of institutional knowledge production, predating modern science by thousands of years. Analyses of science and other systems of collective inquiry have shown that patterns of discovery are shaped not o…

A first-principles mathematical model integrates the disparate timescales of human learning Open
Lifelong learning occurs on timescales ranging from moments to decades. People can lose themselves in a new skill, practice for hours until exhausted, and pursue mastery intermittently over decades. A full understanding of learning require…

Co-speech gesture reveals the spatial foundation of children’s conceptions of time Open
Humans use space to make sense of abstract concepts. Across cultures, for instance, adults rely on mental timelines that conceptualize time metaphorically as a spatial path. Are these spatial models late-arriving "flourishes" or early-deve…

Speed-Quality Tradeoffs Shape the Structure of Decision-Making Collectives Open
Many human groups employ hierarchical decision-making, in which only a few individuals hold the power to make decisions for the collective. A common explanation for the prevalence of hierarchical decision-making is that it provides group-l…

Quirks of cognition explain why we dramatically overestimate the size of minority groups Open
Americans dramatically overestimate the size of African American, Latino, Muslim, Asian, Jewish, immigrant, and LGBTQ populations, leading to concerns about downstream racial attitudes and policy preferences. Such errors are common wheneve…

Divergent and Convergent Creativity Are Different Kinds of Foraging Open
According to accounts of neural reuse and embodied cognition, higher-level cognitive abilities recycle evolutionarily ancient mechanisms for perception and action. Here, building on these accounts, we investigate whether creativity builds …

Brain responses to a lab-evolved artificial language with space-time metaphors Open
What is the connection between the cultural evolution of a language and the rapid processing response to that language in the brains of individual learners? In an iterated communication study that was conducted previously, participants wer…

Multimodality matters in numerical communication Open
Modern society depends on numerical information, which must be communicated accurately and effectively. Numerical communication is accomplished in different modalities—speech, writing, sign, gesture, graphs, and in naturally occurring sett…

Mathematical model bridges disparate timescales of lifelong learning Open
Lifelong learning occurs on timescales ranging from minutes to decades. People can lose themselves in a new skill, practicing for hours until exhausted. And they can pursue mastery over days or decades, perhaps abandoning old skills entire…

Space in Hand and Mind: Gesture and Spatial Frames of Reference in Bilingual Mexico Open
Speakers of many languages prefer allocentric frames of reference (FoRs) when talking about small‐scale space, using words like “east” or “downhill.” Ethnographic work has suggested that this preference is also reflected in how such speake…

Do Metaphors Move From Mind to Mouth? Evidence From a New System of Linguistic Metaphors for Time Open
Languages around the world use a recurring strategy to discuss abstract concepts: describe them metaphorically, borrowing language from more concrete domains. We “plan ahead ” to the future, “count up ” to higher numbers, and “ warm ” to n…

Today is tomorrow’s yesterday: Children’s acquisition of deictic time words Open
Deictic time words like “yesterday” and “tomorrow” pose a challenge to children not only because they are abstract, and label periods in time, but also because their denotations vary according to the time at which they are uttered: Monday’…

Mastering algebra retrains the visual system to perceive hierarchical structure in equations Open
Formal mathematics is a paragon of abstractness. It thus seems natural to assume that the mathematical expert should rely more on symbolic or conceptual processes, and less on perception and action. We argue instead that mathematical profi…

Citizens are not as misinformed as they first appear: Errors in estimates of population size reflect common psychological processes Open
Americans’ tendency to massively overestimate the proportion of Americans who are immigrants, Muslim, LGBTQ, and Latino, but underestimate those who are white or Christian has been well documented and publicized over the past decade. Previ…

Literal and Metaphorical Senses in Compositional Distributional Semantic Models Open
Metaphorical expressions are pervasive in natural language and pose a substantial challenge for computational semantics.The inherent compositionality of metaphor makes it an important test case for compositional distributional semantic mod…
