I always find it amusing when people assert that economics isn’t a science. Such statements suggest that they don’t know what scientists do. Here’s a reminder: Scientists observe the world. They develop theories that aim to explain what they see. They collect data to test their theories and reject those that don’t conform to the data. They try their best to put aside ideological preferences and preconceived notions. Most important, they always remain open to changing their minds when presented with better theories or new data. This approach can be applied whether one is studying apples falling from a tree or gross domestic product fluctuating over time. As Albert Einstein put it: “The whole of science is nothing more than a refinement of everyday thinking.”
