I speak Spanish reasonably well but I find it very tiring … which suggests that I probably think more clearly and ethically in Spanish than in English.
Like so many things, it’s all related to our two different modes of thinking: System1 and System 2. System 1 is fast and efficient and operates below the level of consciousness. It makes a great majority of our decisions, typically without any input from our conscious selves. We literally make decisions without knowing that we’re making decisions.
System 2 is all about conscious thought. We bring information into System 2, think it through, and make reasoned decisions. System 2 uses a lot of calories; it’s hard work. As Daniel Kahneman says, “Thinking is to humans as swimming is to cats; they can do it but they’d prefer not to.”
English, of course, is my native language. (American English, that is). It’s second nature to me. It’s easy and fluid. I can think in English without thinking about it. In other words, English is the language of my System 1. At this point in my life, it’s the only language in my System 1 and will probably remain so.
To speak Spanish, on the other hand, I have to invoke System 2. I have to think about my word choice, pronunciation, phrasing, and so on. It’s hard work and wears me out. I can do it but I would have to live in Spain for a while for it to become easy and fluid. (That’s not such a bad idea, is it?)
You may remember that System 1 makes decisions using heuristics or simple rules of thumb. System 1 simplifies everything and makes snap judgments. Most of the time, those judgments are pretty good but, when they’re wrong, they’re wrong in consistent ways. System 1, in other words, is the source of biases that we all have.
To overcome these biases, we have to bring the decision into System 2 and consider it rationally. That takes time, effort, and energy and, oftentimes, we don’t do it. It’s easy to conclude that someone is a jerk. It’s more difficult to invoke System 2 to imagine what that person’s life is like.
So how does language affect all this? I can only speak Spanish in my rational, logical, conscious System 2. When I’m thinking in Spanish, all my rational neurons are firing. I tend to think more carefully, more thoughtfully, and more ethically. It’s tiring.
When I think in English, on the other hand, I could invoke my System 2 but I certainly don’t have to. I can easily use heuristics in English but not in Spanish. I can jump to conclusions in English but not in Spanish.
The seminal article on this topic was published in 2012 by three professors from the University of Chicago. They write, “Would you make the same decisions in a foreign language as you would in your native tongue? It may be intuitive that people would make the same choices regardless of the language they are using…. We discovered, however, that the opposite is true: Using a foreign language reduces decision-making biases.”
So, it’s true: I’m a better person in Spanish.
