But I thought poverty was the source of all the ills in the world ...

The Pew Research Center’s Global Attitudes Project conducted public opinion surveys in February 2004 in Jordan, Morocco, Pakistan, and Turkey, involving about 1,000 respondents in each country. One of the questions asked was, “What about suicide bombing carried out against Americans and other Westerners in Iraq? Do you personally believe that this is justifiable or not justifiable?” Pew kindly provided me with tab­ulations of these data by respondents’ personal characteristics.

The clear finding was that people with a higher level of education are in general more likely to say that suicide attacks against Westerners in Iraq are justified. I have also broken this pattern down by income level. There is no indication that people with higher incomes are less likely to say that sui­cide-bombing attacks are justified.

Another source of opinion data is the Palestinian Center for Policy and Survey Research, headquar­tered in Ramallah. The center collects data in the West Bank and Gaza Strip. One question, asked in December 2001 of 1,300 adults, addressed attitudes toward armed attacks on Israeli tar­gets. Options were “strongly support,” “support,” “oppose,” “strongly oppose,” or “no opinion.”

Support turned out to be stronger among those with a higher level of education. For exam­ple, while 26 percent of illiterates and 18 per­cent of those with only an elementary education opposed or strongly opposed armed attacks, the figure for those with a high school education was just 12 percent. The least supportive group turned out to be the unemployed, 74 percent of whom said they support or strongly back armed attacks. By comparison, the support level for merchants and professionals was 87 percent.

Related findings have been around for a long time. Daniel Lerner, a professor at MIT at the time, published a book in 1958 called The Passing of Traditional Society in which he collected and analyzed data on extremism in six Middle Eastern countries. He concluded that “the data obviate the conventional assumption that the extremists are simply the have-nots. Poverty prevails only among the apolitical masses.”
