Contact: The consequences of growing up amid diversity just discussed bring us to the effects of prolonged contact on Us/Theming. In the 1950s the psychologist Gordon Allport proposed “contact theory.” Inaccurate version: bring Us-es and Thems together (say, teenagers from two hostile nations in a summer camp), animosities disappear, similarities start to outweigh differences, everyone becomes an Us. More accurate version: put Us and Thems together under narrow circumstances and something sort of resembling that happens, but you can also blow it and worsen things.
Some of the effective narrower circumstances: each side has roughly equal numbers; everyone’s treated equally and unambiguously; contact is lengthy and on neutral territory; there are “superordinate” goals where everyone works together on a meaningful task (say, summer campers turning a meadow into a soccer field).
How do we bring people who disagree back together? Technology is really good at getting people to do things which are individually gratifying so how do we encourage individuals to do something which is individually difficult but will have a strong positive effect on society?
