Scientists who scanned European al Qaeda supporters' brains found reduced activity

Brain scans on fanatical Islamists show they have a reduced capacity for rational thought, new research suggests. Members of a radical Islamist group were asked how willing they were to'fight and die' for their ideas. Their brains were then scanned during the process. The results showed that when questioned, the part of the brain that engages in evaluating costs and consequences showed reduced activity. The scientists say this shows that when it comes to values held'sacred' to the radicals, they are immune to arguments involving costs and benefits.
