TED Talk: How Language Shapes the Way We Think – Lera Boroditsky

SUMMARY

The speaker begins by drawing attention to the remarkable human ability to communicate

through language. By producing simple sounds, humans can transmit highly complex thoughts,

ideas, and images across space and time. Language allows us not only to share knowledge but

also to create entirely new thoughts in someone else’s mind—for example, imagining a

jellyfish waltzing in a library. This raises an ancient and central question: does language shape

the way we think? Thinkers from Charlemagne, who believed each language grants a “second

soul,” to Shakespeare, who suggested names and words may not matter, have debated this

issue. Until recently, the debate lacked scientific evidence, but modern linguistic and cognitive

research now provides insights.

The speaker presents a series of striking examples:

1. Spatial orientation – In Kuuk Thaayorre, an Aboriginal language in Australia, speakers

do not use “left” or “right” but rely entirely on cardinal directions (north, south, east,

west). Even greetings are tied to orientation. As a result, speakers of this language are

extraordinarily good at staying oriented in space—something English speakers struggle

with, as shown when an audience fails to identify southeast with eyes closed. This

demonstrates that language and culture can train humans to develop cognitive skills

previously thought to be biologically limited.

2. Time perception – In English, time is usually organized left to right, reflecting writing

direction. Hebrew and Arabic speakers, by contrast, arrange time from right to left. The

Kuuk Thaayorre again show a different approach: they arrange time east to west,

aligned with the movement of the sun across the landscape. Unlike egocentric English

speakers, whose concept of time shifts with body orientation, the Kuuk Thaayorre

anchor time to the external world. This shows that even fundamental concepts like time

are shaped by linguistic patterns.

3. Numbers and counting – Some languages lack precise number words such as “seven”

or “eight.” Speakers of these languages cannot count exactly or easily match quantities.

In contrast, speakers of languages with number systems acquire the ability to

manipulate abstract mathematics. Number words, therefore, act as a crucial “cognitive

tool” that opens access to complex reasoning, algebra, and science.

4. Color distinctions – Languages differ in how they divide the color spectrum. English

has a single word “blue,” while Russian requires distinguishing between “goluboy”

(light blue) and “siniy” (dark blue). Russian speakers, accustomed to making this

distinction in daily speech, are quicker to perceive differences between light and dark

blue, and their brains register these shifts more categorically than English speakers.

Thus, language can even influence basic perception.

5. Grammatical gender – Many languages assign gender to nouns. These grammatical

categories influence thought in subtle ways. For instance, in German, “bridge” is

feminine, while in Spanish it is masculine. German speakers often describe bridges with

adjectives like “elegant” or “beautiful,” while Spanish speakers tend to say “strong” or

“sturdy.” The arbitrary assignment of gender alters how speakers perceive and describe

the same object.

6. Events, agency, and blame – English encourages agent-focused descriptions (“He broke

the vase”), even for accidents. Spanish, however, often frames such events passively

(“The vase broke”). This linguistic difference shapes memory and judgment: English

speakers tend to remember who was responsible, while Spanish speakers are more

likely to recall that it was accidental. Moreover, English speakers assign more blame

and punishment when the language emphasizes agency. This has practical implications

for eyewitness testimony, legal reasoning, and moral judgment.

From these examples, the speaker highlights that language influences thought in different

dimensions:

• Broad frameworks, like how space and time are conceptualized.

• Deep cognitive abilities, such as mathematics enabled by number words.

• Basic perceptual processes, as in color discrimination.

• Wide-ranging categories like gender, which affect descriptions of everyday objects.

• Personally significant judgments, including memory, blame, and responsibility.

The broader conclusion is that human languages, numbering around 7,000 worldwide,

represent 7,000 cognitive universes. Each language offers its speakers unique ways of

perceiving, organizing, and interpreting reality. Yet this richness is under threat, as one

language is lost every week, and nearly half may disappear within a century. The tragedy is

compounded by the fact that most cognitive science research relies almost exclusively on

American, English-speaking undergraduates, ignoring the vast diversity of human linguistic

experience.

The talk closes with a reflective challenge: these findings are not just about “other people.”

The language you speak shapes your own mind. This awareness opens the possibility of asking:

Why do I think the way I do? How else could I think? What new thoughts might I want to create

through language?
