Dangers of the group mentality
Alan Judd on Marc Sageman's latest book Marc Sageman is deservedly one of the best-known academics working on terrorism. A clinical psychologist and former CIA officer, in 2004 he published Understanding Terror Networks, a book which enlarged the way the subject was seen. Hitherto, most researchers and governments had located the ‘root causes’ of terrorism either in religion (Islam) or in social and economic conditions. A third approach, the biographical, offered fascinating case-histories of terrorists thought to be mad or incomprehensibly evil and who generally turned out to be rather more commonplace. Sageman’s achievement was to start with evidence, not theory.
