Language as a Cognitive Superpower: How Humans Learn Faster
Cecilia Heyes labels language a 'cognitive gadget' for precise social learning
Language is not the engine of thought. It is a tool, remarkably precise, yet fundamentally optional to the mind that wields it. That, at least, is the provocative claim at the heart of cognitive scientist Cecilia Heyes’s latest argument.
She calls language a “cognitive gadget,” an evolutionary contraption that lets humans learn from one another with surgical accuracy. Strip away our ability to speak, and we remain thinking, reasoning, loving beings. Strip language from a large language model, and you are left with empty code.
This asymmetry has profound consequences: if AI enthusiasts believe text-based training alone can forge general intelligence, they may be mistaking the scaffolding for the cathedral.
Understood this way, language is what the cognitive scientist Cecilia Heyes calls a "cognitive gadget" that "enables humans to learn from others with extraordinary efficiency, fidelity, and precision." Our cognition improves because of language -- but it's not created or defined by it. Take away our ability to speak, and we can still think, reason, form beliefs, fall in love, and move about the world; our range of what we can experience and think about remains vast. But take away language from a large language model, and you are left with literally nothing at all.
An AI enthusiast might argue that human-level intelligence doesn't need to necessarily function in the same way as human cognition. AI models have surpassed human performance in activities like chess using processes that differ from what we do, so perhaps they could become superintelligent through some unique method based on drawing correlations from training data. But there's no obvious reason to think we can get to general intelligence -- not improving narrowly defined tasks --through text-based training.
After all, humans possess all sorts of knowledge that is not easily encapsulated in linguistic data -- and if you doubt this, think about how you know how to ride a bike. In fact, within the AI research community there is growing awareness that LLMs are, in and of themselves, insufficient models of human intelligence.
Language is a tool, not a soul. It sharpens our thought, but it does not conjure it from nothing. We can lose the words and still keep the world, the feel of a bike beneath us, the ache of love, the quiet certainty of a belief held without explanation.
An LLM, by contrast, is a ghost that vanishes when the text goes dark. Its intelligence is a library without a reader. The AI community is waking up to this: pattern-matching on petabytes of prose is not a path to general intelligence.
It is a spectacular parlor trick, but a trick nonetheless. True cognition reaches beyond the sentence, into muscle memory, into the unsaid, into the spaces between. Language is a gadget we wield, not the wizard that wields us.

Common Questions Answered
How does Cecilia Heyes describe language as a 'cognitive gadget'?
Heyes views language as a learned social tool that dramatically enhances human learning capabilities, rather than an innate biological trait. She argues that language enables humans to learn from each other with extraordinary efficiency, precision, and accuracy, functioning more like a sophisticated cognitive mechanism than a hardwired communication system.
Can humans think and reason without language according to Heyes' perspective?
Yes, Heyes suggests that humans can think, reason, form beliefs, and experience the world independently of language. Her perspective emphasizes that cognition exists separately from linguistic ability, with language serving as an additional tool that enhances social learning and communication.
What makes language a powerful social learning mechanism in Heyes' theory?
Language acts as a 'cognitive gadget' that allows humans to learn from each other with remarkable efficiency and precision. By enabling more accurate transmission of complex information and experiences, language supercharges our ability to share knowledge and understand each other's perspectives in ways that go beyond basic communication.
