I have become more and more data-driven as I get older, especially when it comes to “big picture” things like politics, economics and security. Although like anything it can be manipulated, it is much easier to spot the manipulation if we can all look at the model and the underlying data. One of my favorite authors on the subject of security (in various forms from computers and networks to physical security issues and terrorism) is Bruce Schneier. He gave a talk at TEDxPSU last year and it is now available on TED – well worth watching.
