🧠 Do We Think Differently in Another Language?

Have you ever noticed that you feel slightly different when you speak English, French, Spanish or another foreign language?

Maybe you are more confident, less emotional, funnier — or simply more direct.

This isn't necessarily your imagination. Research suggests that the language we use can influence our emotions, decisions and behaviour. Scientists call one part of this the “foreign language effect.” (The Guardian)

🌍 One language, one mindset?

Imagine you are making an important decision. In your native language, the situation may feel very personal and emotional. In a foreign language, you might feel slightly more detached.

For example, researchers have found that people can be less influenced by certain emotional biases and more willing to take calculated risks when making decisions in a foreign language. A 2022 meta-analysis found a small but significant foreign-language effect on decision-making. (Cambridge University Press)

One famous experiment involved the classic trolley problem: would you sacrifice one person to save five others? Participants were more likely to choose the utilitarian option when considering the dilemma in a foreign language. (The Guardian)

So, could switching languages help you think more rationally?

Sometimes — but don't expect your second language to turn you into Spock. 🖖

The effect is real enough to have been studied extensively, but scientists are still investigating exactly why it happens and when it appears. More recent research also suggests that the effect can vary depending on factors such as language experience and context. (Cambridge University Press)

🎭 Do we have a different personality in another language?

You may have heard bilingual people say:

“I'm a completely different person when I speak English.”

There may be something behind this — but probably not in the way you think.

Speaking another language can activate different cultural expectations and social behaviours. You might become more formal in German, more expressive in Spanish, more restrained in English — not because the language has magically changed your personality, but because you are also changing your social and cultural context.

Research with Chinese-English bilinguals, for example, found that language use and cultural context could influence how people expressed different personality traits. (PubMed)

Think of it as having different settings rather than different personalities.

You are still you — but different sides of you may become more noticeable.

💭 A foreign language can create emotional distance

Your mother tongue is usually connected to your earliest memories, family, childhood and strong emotional experiences.

A language learned later in life may feel more “neutral”.

This can have an interesting effect: using a second language may create a little emotional distance from what you are saying or thinking.

Research has even explored whether recalling difficult experiences in a foreign language can reduce emotional distress. (The Guardian)

That doesn't mean you should suddenly discuss all your problems in French! 🇫🇷 But it helps explain why saying “I love you” in your native language may feel much more intense than saying the same words in a language you learned at 20.

🧠 Is speaking several languages good for the brain?

Learning another language is certainly mentally demanding.

When bilingual people speak, their brain has to manage more than one linguistic system. Both languages can remain active, so speakers constantly need to select the appropriate language and manage interference. Research has found effects of bilingual experience on brain function and structure. (ScienceDirect)

But here's an important caveat: “bilingualism makes you smarter” is too simple.

Scientists still debate how much bilingualism improves general cognitive abilities such as executive function. A 2023 review in Nature Reviews Psychology notes that the evidence is mixed and that some apparent advantages may come from the specific experience of using two languages rather than a general cognitive boost. (Nature)

So don't learn Italian because someone promised you a superhuman brain. 😄

Learn it because you're making your brain do something complicated, flexible and new.

🇪🇺 And perhaps that's the biggest benefit

Learning a language isn't simply learning new words.

You are learning:

• 🧠 new ways of expressing ideas

• 🎭 different ways of presenting yourself

• 🌍 another cultural perspective

• 🔄 mental flexibility

• 🗣️ new ways of communicating with people

And sometimes, switching languages can give you a slightly different perspective on the same situation.

So the next time you switch from Serbian to English, don't worry about having an accent or searching for the perfect word.

You may be doing something much more interesting:

you are training your brain to see the world through another linguistic lens. 🌍
