“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.
