When you speak another language, you become someone else (and science proves it)

Have you ever had that strange feeling?

You speak French with your friends. You feel a certain way. Calm, maybe a little reserved.

Then you switch to English or Spanish. And suddenly, without even realizing it, you’re not quite the same person anymore. You laugh louder. You’re more direct. More expressive. You make jokes you would never make in your native language.

You tell yourself it’s all in your head. That you’re playing a role.

In reality, what you’re experiencing has a scientific name. And it’s one of the most fascinating transformations that an internship abroad can offer you.

The Phenomenon Has a Name: The Bilingual Personality

When you change languages, you change mental frameworks. Your emotions, your tone, your reactions, everything shifts toward another version of yourself.

Researchers in psycholinguistics have confirmed this since the 1960s: this phenomenon is called the Bilingual Personality Hypothesis. According to them, your personality is not fixed. It is fluid, and the language you speak acts like a lens that colors the way you experience the world.

You’re not schizophrenic. You’re simply multidimensional. And that’s excellent news.

What Science Says (Concretely)

One of the first researchers to document this phenomenon was Susan Ervin-Tripp, a psycholinguist from Berkeley.

In 1968, she asked Japanese-American women living in San Francisco to complete the same sentences in Japanese and then in English.

The result?

To the sentence “When my desires conflict with my family…”, here were the responses:

• In Japanese: “…it is a time of great unhappiness.”
• In English: “…I do what I want.”

Why such a difference? Because each language activates a different cultural framework in the brain. In Japanese, the culture of family harmony takes over: conflict with loved ones becomes painful. In English, it is the American culture of individualism that speaks: asserting yourself becomes natural, almost obvious.

These women are not lying. They genuinely feel both realities.

More recent studies confirm it: according to research conducted among Mexican-American bilinguals, participants scored higher in extraversion, openness, and confidence when taking tests in English rather than Spanish.

Language is not neutral. It transforms you.

Why Does This Happen?

Every language carries within it:

• a culture (codes, values, references)
• a rhythm (the speed of English, the warmth of Spanish)
• emotions (some words exist in one language but not another)
• a relationship to the world (politeness, hierarchy, intimacy)

When you immerse yourself in a new language, your brain aligns with these codes. You become more direct in English because it is a language of action. Warmer in Spanish because it is a language of emotion. More structured in German because it is a precise language.

You’re not pretending. You’re embodying another side of yourself.

Why It’s a Superpower

Here’s the real magic: living in another language reveals parts of yourself you didn’t know existed.

You discover:

• That you can be funnier than you thought
• That you can be more assertive without being aggressive
• That you can speak in front of 20 people without panicking
• That you can flirt, negotiate, and defend an idea with ease

This new version of yourself has always been inside you. It was just waiting for another language to come out.

And the best part? Once you’ve unlocked it, you bring it back home with you. You return more open-minded, freer, and more yourself.

The “Third Culture Identity” Effect

Young graduates who have spent several months abroad develop what anthropologists call a third culture identity, an identity that is no longer solely French, but something between multiple cultures.

You integrate the best codes from each culture:

• German efficiency
• Spanish friendliness
• Dutch honesty
• British humor
• Italian elegance

And you come back with an upgraded version of yourself, capable of navigating any context.

That’s exactly what the best companies are looking for today.

The Superpower on the Job Market

On a resume, it may not be immediately visible. But during an interview, you can feel it instantly.

A candidate who has completed an internship in Madrid or Berlin has:

• a different presence
• stronger verbal confidence
• rare behavioral flexibility
• the ability to adapt to any type of person

International recruiters detect it within 30 seconds. And that’s what makes all the difference between you and another “academically perfect” profile who has never left their comfort zone.

Several studies show that multilingual people develop stronger emotional intelligence: they know how to read social codes, adapt their communication, and negotiate in complex environments.

These are the profiles everyone wants to hire.

How to Trigger This Transformation

Spoiler: it doesn’t happen by watching Netflix in the original version.

You can know all the grammar and vocabulary of a language, but you won’t become “another version of yourself” until you actually live inside that language.

You need to:

• live in the language (at work, in the street, at parties)
• miss jokes, expressions, and hidden meanings
• observe how locals interact
• let yourself be influenced by their rhythm, tone, and humor

This immersion is what creates the transformation. Not evening classes.

And that’s exactly what an internship abroad allows you to do, far better than a short Erasmus exchange or a tourist trip.
