In the deal presented to Israeli settlers, the Palestinians "would give up any claims to their right of return" or "would be required to recognize the historic and legitimate right of the Jewish people to Eretz Israel"; in that presented to the Palestinians, Israel "would recognize the historic and legitimate right of the Palestinians to their own state and would apologize for all wrongs done to the Palestinian people," or would "give up what they believe is their sacred right to the West Bank" or would "symbolically recognize the historic legitimacy of the right of return in fact granting it". In summarizing the result, cognitive psychologist Steven Pinker claims, "Unlike the bribes of money or peace, the symbolic concession of a sacred value by the enemy, especially when it acknowledges a sacred value on one's own side, reduced the absolutists' anger, disgust, and willingness to endorse violence."
