WEIRD

You're WEIRD:

Did you know that the famous Ultimatum Game doesn't play out the same way in other cultures? Westerners famously reject unfair offers:

It seems most of humanity would play the game differently. Joseph Henrich of the University of British Columbia took the Ultimatum Game into the Peruvian Amazon as part of his work on understanding human co-operation in the mid-1990s and found that the Machiguenga considered the idea of offering half your money downright weird — and rejecting an insultingly low offer even weirder.

"I was inclined to believe that rejection in the Ultimatum Game would be widespread. With the Machiguenga, they felt rejecting was absurd, which is really what economists think about rejection," Dr. Henrich says. "It's completely irrational to turn down free money. Why would you do that?"

It turns out the Machiguenga — whose number system goes: one, two, three, many — are not alone in their thinking. Most people from non-Western cultures introduced to the Ultimatum Game play differently than Westerners. And that is one clue that the Western mind differs in fundamental ways from the rest of humanity, according to Dr. Henrich. He and two other UBC researchers authored a paper shaking up the fields of psychology, cognitive science and behavioural economics by questioning whether we can know anything about humanity in general if we only study a "truly unusual group of people" — the privileged products of Western industrial societies, who just happen to make up the vast majority of behavioural science test subjects.

The article, titled "The weirdest people in the world?", appears in the current issue of the journal Brain and Behavioral Sciences. Dr. Henrich and co-authors Steven Heine and Ara Norenzayan argue that life-long members of societies that are Western, educated, industrialized, rich, democratic — people who are WEIRD — see the world in ways that are alien from the rest of the human family. The UBC trio have come to the controversial conclusion that, say, the Machiguenga are not psychological outliers among humanity. We are.
