"Why do some individuals decide to break with society and embark on a career in terrorism? Do terrorists share common traits or characteristics? Is there a terrorist personality or profile? Can a terrorist profile be developed that could reliably help security personnel to identify potential terrorists, whether they be would-be airplane hijackers, assassins, or suicide bombers? Do some terrorists have a psychotic (see Glossary) personality? Psychological factors relating to terrorism are of particular interest to psychologists, political scientists, and government officials, who would like to be able to predict and prevent the emergence of terrorist groups or to thwart the realization of terrorist actions. This study focuses on individual psychological and sociological characteristics of terrorists of different generations as well as their groups in an effort to determine how the terrorist profile may have changed in recent decades, or whether they share any common sociological attributes. This study is not about terrorism per se. Rather, it is concerned with the perpetrators of terrorism. Prepared from a social sciences perspective, it attempts to synthesize the results of psychological and sociological findings of studies on terrorists published in recent decades and provide a general assessment of what is presently known about the terrorist mind and mindset."
