The New York times has an op-ed piece titled “Republicans Against Science.” What’s ironic is the fact that it’s written by Keynesian economics Paul Krugman. That’s a bit like a pot calling a kettle black. Keynesians like to tout their scientific approach to economics through the use of empirical and mathematical methods but being economics isn’t a natural science, and individual factors can’t be isolated, traditional scientific methods prove to be almost completely useless. Any scientist will point out the fact that you have to use the right tool for the job and the only effective tool for studying economics is praxeology.
