Writers and thinkers have long felt the creative benefits of international travel. Ernest Hemingway, for example, drew inspiration for much of his work from his time in Spain and France. Aldous Huxley, the author of Brave New World, moved from the U.K. to the U.S. in his 40s to branch out into screenwriting. Mark Twain, who sailed around the coast of the Mediterranean in 1869, wrote in his travelogue Innocents Abroad that travel is “fatal to prejudice, bigotry, and narrow-mindedness.”

In recent years, psychologists and neuroscientists have begun examining more closely what many people have already learned anecdotally: that spending time abroad may have the potential to affect mental change. In general, creativity is related to neuroplasticity, or how the brain is wired. Neural pathways are influenced by environment and habit, meaning they’re also sensitive to change: New sounds, smells, language, tastes, sensations, and sights spark different synapses in the brain and may have the potential to revitalize the mind.
“Foreign experiences increase both cognitive flexibility and depth and integrativeness of thought, the ability to make deep connections between disparate forms,” says Adam Galinsky, a professor at Columbia Business School and the author of numerous studies on the connection between creativity and international travel. Cognitive flexibility is the mind’s ability to jump between different ideas, a key component of creativity. But it’s not just about being abroad, Galinsky says: “The key, critical process is multicultural engagement, immersion, and adaptation. Someone who lives abroad and doesn’t engage with the local culture will likely get less of a creative boost than someone who travels abroad and really engages in the local environment.” In other words, going to Cancun for a week on spring break probably won’t make a person any more creative. But going to Cancun and living with local fishermen might.
In Galinsky’s latest study, published last month in the Academy of Management Journal, he and three other researchers examined the experiences of the creative directors of 270 high-end fashion houses. Combing through 11 years’ worth of fashion lines, Galinsky and his team searched for links between the creative directors’ experience working abroad and the fashion houses’ “creative innovations,” or the degree “to which final, implemented products or services are novel and useful from the standpoint of external audiences.” The level of creativity of a given product was rated by a pool of trade journalists and independent buyers. Sure enough, the researchers found a clear correlation between time spent abroad and creative output: The brands whose creative directors had lived and worked in other countries produced more consistently creative fashion lines than those whose directors had not.
The researchers also found that the more countries the executives had lived in, the more creative the lines tended to be—but only up to a point. Those who had lived and worked in more than three countries, the study found, still tended to show higher levels of creativity that those who hadn’t worked abroad at all, but less creativity that their peers who had worked in a smaller number of foreign countries. The authors hypothesized that those who had lived in too many countries hadn’t been able to properly immerse themselves culturally; they were bouncing around too much. “It gets back to this idea of a deeper level of learning that’s necessary for these effects to occur,” Galinsky says.
Cultural distance, or how different a foreign culture is from one’s own, may also play a role: Surprisingly, Galinsky and his colleagues found that living someplace with a larger cultural distance was often associated with lower creativity than living in a more familiar culture. The reason for that, they hypothesized, was that an especially different culture might come with a bigger intimidation factor, which may discourage people from immersing themselves in it—and no immersion, they explained, could mean none of the cognitive changes associated with living in another country.
Cross-cultural experiences have the potential to pull people out of their cultural bubbles, and in doing so, can increase their sense of connection with people from backgrounds different than their own. “We found that when people had experiences traveling to other countries it increased what’s called generalized trust, or their general faith in humanity,” Galinsky says. “When we engage in other cultures, we start to have experience with different people and recognize that most people treat you in similar ways. That produces an increase in trust.”
This trust may play an important role in enhancing creative function. In a 2012 study out of Tel Aviv University, researchers found that people who “believe that racial groups have fixed underlying essences”—beliefs the authors termed “essentialist views”—performed significantly worse in creative tests than those who saw cultural and racial divisions as arbitrary and malleable. “This categorical mindset induces a habitual closed-mindedness that transcends the social domain and hampers creativity,” the study authors wrote. In other words, those who put people in boxes had trouble thinking outside the box.
Of course, although a new country is an easy way to leave a “social comfort zone,” the cultural engagement associated with cognitive change doesn’t have to happen abroad. If a plane ticket isn’t an option, maybe try taking the subway to a new neighborhood. Sometimes, the research suggests, all that’s needed for a creative boost is a fresh cultural scene.
