Queueing theory, a tool for assessing the resources required to provide a service, is commonly used for predicting waiting times for call centers. Yale’s Edward Kaplan used it to analyze terror plots and found there are an average of three jihadi terror plots in the works at any time in the U.S. and at least 80% are stopped before anyone is hurt. "The reality is that we’re far safer than we often feel," Kaplan writes in the Boston Globe Magazine. The odds of dying from a terrorist attack: 1 in 20 million. The risk of being killed by lightning: 1 in 126,000; dying in a firearm assault: 1 in 340; succumbing to heart disease or cancer: 1 in 7.
