南方离婚率低因为爱吃米 In China, as in many countries, the north-south divide runs deep. People from the north are seen as hale and hearty, while southerners are often portrayed as cunning, cultured traders. Northerners are taller than southerners. The north eats noodles, while the south eats riceand according to new research, when it comes to personality, that difference has meant everything。 A study published Friday by a group of psychologists in the journal Science finds that Chinas noodle-slurping northerners are more individualistic, show more analytic thought and divorce more frequently. By contrast, the authors write, rice-eating southerners show more hallmarks traditionally associated with East Asian culture, including more holistic thought and lower divorce rates。 The reason? Cultivating rice, the authors say, is a lot harder. Picture a rice paddy, its delicate seedlings tucked in a bed of water. They require careful tending and many hours of laborby some estimates, twice as much as wheatas well as reliance on irrigation systems that require neighborly cooperation. As the authors write, for southerners growing rice, strict self-reliance might have meant starvation。 Growing wheat, by contrast, the norths staple grain, is much simpler. One Chinese farming guide from the 1600s quoted in the study advised aspiring farmers that if one is short of labor power, it is best to grow wheat。 |
