People are people, all over the world. At the same time, though, cultures can be quite different from place to place. How much does the place have to do with the culture that evolves there?

Arizona State University researchers Alexandra Wormley and Michael Varnum are social psychologists. Their field has been zeroing in on fascinating connections – like the observation that places with less access to water tend to have cultures that are more forward-looking. When fresh water is scarce, they write, “there is more need to plan so that it doesn’t run out,” or so the thinking goes.

Wormley and Varnum compiled a data set based on how 200 societies ranked on nine key features of ecology and dozens of aspects of cultural variation. They identified a number of previously unnoticed relationships between the ecology and the culture of particular societies – and even quantified how much of these differences can be traced to environmental factors.
