This paper examines how violence in the Second Intifada influences Palestinian public opinion. Using public opinion poll micro data linked to data on fatalities, we find that although Israeli violence discourages Palestinians from supporting moderate political positions, this “radicalization” is fleeting, and vanishescompletely within 90 days. We do find evidence suggesting that major political events in the Palestinian-Israeli conflict have had a longer-term impact on political preferences. Individuals who were teenagers during the period of the Oslo negotiations tend to have relatively moderate preferences, while those who were teenagers during the First Intifada tend to be relatively radical.
