The Null Device
A recent study at the John F. Kennedy School of Government claims to disprove the often cited anecdotal connection between poverty and terrorism. According to the report, a nation's poverty has little effect on the occurrence of terrorism in that nation; however, levels of political freedom strongly influence terrorism. Countries with high levels of freedom and strictly controlled autocracies are both less susceptible to terrorism than countries with intermediate levels of freedom (this can be seen in Iraq and Russia). Perhaps it has to do with the intermediate countries not having cultural institutions which evolved with their recently gained freedom, or having insufficient freedom to provide peaceful outlets for grievances whilst insufficient control to effectively clamp down on violent ones.
Another factor which increases a country's frequency of terrorism is apparently geography, with mountainous terrain, jungle and similar features offering safe havens to rogue groups, as well as sources of narcotics-related income. (via bOING bOING)
