Does the language you speak create your reality?

Lera Boroditsky: How language shapes the way we think · 11:46 · Video: TED · Watch at the source

In short: With roughly 7,000 languages spoken globally, humanity has constructed 7,000 different cognitive universes. From how we perceive colors to how we orient ourselves in space, the structures of our speech may do more than just communicate thoughts—they may fundamentally shape the very way we think.

The question of whether linguistic structures influence cognition is an ancient one. As the Holy Roman emperor Charlemagne once suggested, possessing a second language is akin to having a second soul. This implies that language is not merely a neutral tool for transmitting information, but a framework that crafts our perception of reality. Cognitive scientist Lera Boroditsky argues that the answer to whether language shapes thought is a resounding yes, pointing to the incredible flexibility of the human mind. This concept suggests that our speech acts as a lens for our experiences. It highlights how linguistic diversity reveals the immense ingenuity of the human brain.

Evidence for this connection can be found in how different cultures navigate and categorize the world. For instance, some Aboriginal communities in Australia do not rely on relative terms like 'left' or 'right.' Instead, they utilize cardinal directions to orient themselves, fundamentally altering their spatial awareness. Similarly, linguistic nuances in vocabulary can change perception; in Russian, for example, there are multiple distinct words used to describe shades of blue.

This capacity for language is a unique human ability that allows us to transmit complex, even bizarre, ideas across vast reaches of space and time. By converting air vibrations into structured thoughts, we can plant entirely new concepts in another person's mind—such as a jellyfish waltzing in a library while contemplating quantum mechanics. This ability to transmit knowledge across minds highlights the profound power of the 7,000 diverse linguistic structures that exist today. This process begins when we make specific sounds through exhaling. These tones and hisses create vibrations that eventually reach the listener's eardrums.
