How Language Secretly Shapes Your Personality

Cognitive scientist Lera Boroditsky studies how humans think and how we get so smart—not individually, but as a group. A big part of that answer, she explains, is language and culture. The languages we marinate in contain intellectual property developed by thousands of years of ancestors, and we absorb it as children as if it were just part of the air we breathe. Yet we all walk around believing we experience reality directly and objectively, when in fact each of us is using a different set of filters.

Language Creates Different Selves

Boroditsky grew up speaking Russian in Ukraine and Belarus before learning English at age twelve. She confirms what many bilinguals report: speaking different languages can make you feel like a different person. This isn't just about context—one language being the language of childhood, another of work. There are structural elements of language that lead you to think one way or another depending on which language you're using in the moment.

What you'll learn

1 (00:04) **Bilingual Identity & the Illusion of Communication** - Lera Boroditsky reveals she grew up speaking Russian and started English at age twelve; Trevor notes he cannot detect a foreign accent in her speech.
2 (21:27) **What a Cognitive Scientist Actually Studies** - Boroditsky distills her work into a simple question: how humans think and how they get so smart as a group.
3 (23:38) **Language Shapes Personality: You Are a Different Person in Different Languages** - Boroditsky confirms that bilinguals think differently depending on which language they are using, and many feel like almost a different person.
4 (27:43) **Why Perfect Translation Is Impossible** - Every language is a complex, interconnected system where words exist in relation to each other, making exact translation across systems impossible.
5 (33:01) **Dreaming in Another Language & Comprehension vs. Production** - Boroditsky explains that the language you dream in can switch quickly, even for languages you don't speak well.
6 (37:31) **Is English the Easiest Language?** - English is not inherently easier to learn; its speakers are just more accustomed to hearing it spoken badly by second-language learners.
7 (38:40) **Political Fights & the Illusion of Shared Words** - Many arguments happen because we use the same words (like "freedom") but point to completely different concepts.

Does the language you speak shape how you see the world? Cognitive scientist Lera Boroditsky joins Trevor, Eugene, and Dave to explore how our native tongue can influence everything from our personalities to who we blame when things go wrong, and why bilingual people can feel different depending on which language they're speaking. They dive into cultures that navigate using north, south, east, and west instead of left and right, the relationship between language and thought, and why we're all susceptible to the illusion that we're better at communicating than we actually are. It’s a funny, mind-expanding conversation about how the words we use may shape far more of our world than we realize.
