“The impact that shifting languages can have on us reveals how central it is to our identities and social connections. In a series of intriguing studies, Boaz Keysar and his colleagues at the University of Chicago have shown that when speaking a second language, people tend to behave more rationally. In our native languages, we’re somewhat stuck in our habits, and likely to be susceptible to classic cognitive biases. But the more thoughtful effort that is required to speak a second language helps elevate us into more rational territory.”
