Field experiments with 601 settlers tested compromise on land and right of return.

Evidence

In September 2005 we conducted our first field experiments (Ginges, Atran, Medin, & Shikaki, 2007) in the West Bank and Gaza to test the effect of different forms of incentives on the willingness of a representative sample of 601 Jewish settlers to compromise over two key issues in the Israeli–Palestinian conflict: exchanging land for peace, and recognizing the legitimacy of the right of return for Palestinian refugees. — Scott Atran and Jeremy Ginges, Sacred Values and Cultural Conflict, 26
