The language we speak influences behavior in surprising ways. Derek Thompson from The Atlantic shares new research from economist Keith Chen. In the 1930s, linguists proposed that the way we read, write, and talk helped to determine the way we see the world. Speakers of languages that had the same word for orange and yellow had a harder time actually distinguishing the colors. Speakers of the Kook Thaayorre language, which has no words for left and right, must orient themselves by north, south, east, and west at all time, which enhances their awareness of geographical and astronomical markers.
Last year, economist Keith Chen released a working paper (now published) suggesting speakers of languages without strong future tenses tended to be more responsible about planning for the future. Quick example. In English, we say "I will go to the play tomorrow." That's strong future tense. In Mandarin or Finnish, which have weaker future tenses, it might be more appropriate to say, "I go to the play tomorrow."
Chen wondered whether languages with weak future tenses would be more thoughtful about the future because they consider it, grammatically, equivalent to the present. He mapped stronger and weak future-tense languages across Europe and correlated the data with future-oriented behaviors like saving, smoking, and using condoms.
Remarkably, he discovered that speakers with weak future tenses (e.g. German, Finnish and Estonian) were 30 percent more likely to save money, 24 percent more likely to avoid smoking, 29 percent more likely to exercise regularly, and 13 percent less likely to be obese, than speakers of languages with strong future tenses, like English.
