From the research paper:
"It’s about another exotic group: people from Western, Educated, Industrialized, Rich, and Democratic (WEIRD) societies. In particular, it’s about the Western, and more specifically American, undergraduates who form the bulk of the database"
The article seemed to blur the lines quite a bit; I thought the original question was justified and not worthy of downvotes. (why are we downvoting people that ask questions, or maybe, just maybe, misunderstood something?)
>more than 96 percent of the subjects tested in psychological studies from 2003 to 2007 were Westerners—with nearly 70 percent from the United States alone.
And I didnt see any data from what happens when they did the "money game" with Europeans, Asians, Africans, even developed South Americans.
"Recent comparative work has dramatically altered this initial picture. Two unified projects (which we call Phase 1 and Phase 2) have deployed the Ultimatum Game and other related experimental tools across thousands of sub- jects randomly sampled from 23 small-scale human societies, including foragers, horticulturalists, pastoralists, and subsistence farmers, drawn from Africa, Amazonia, Oceania, Siberia, and New Guinea"
There's been at least one meta-analysis of data with the game: http://www.econ.nagoya-cu.ac.jp/~yhamagu/ultimatum.pdf It doesn't really come to anything approaching a definitive conclusion though; in general, results vary for reasons that are unclear.
Where is the comparison to other more civilized people like Europeans, Asian countries, Africans, or even Russians.
