This paper proposes an experimental approach to studying different aspects
of discrimination. We let participants play various games with opponents of
distinct ethnic affiliation. Strategies based upon such ethnic affiliation
provide direct evidence of ethnic discrimination. This approach was utiliz
ed to study ethnic discrimination in Israeli Jewish society. Using the "tru
st game," we detected a systematic mistrust toward men of Eastern origin. A
"dictator game" experiment indicated that this discrimination was due to (
mistaken) ethnic stereotypes and not to a "taste for discrimination." The "
ultimatum game" enabled us to trace another ethnic stereotype that reversed
the discrimination's direction. One of the surprising results is that this
ethnic discrimination is an entirely male phenomenon.
