I want to pause here and talk about this notion of consensus, and the rise of what has been called consensus science. I regard consensus science as an extremely pernicious development that ought to be stopped cold in its tracks. Historically, the claim of consensus has been the first refuge of scoundrels; it is a way to avoid debate by claiming that the matter is already settled. Whenever you hear the consensus of scientists agrees on something or other, reach for your wallet, because you're being had. Let's be clear: the work of science has nothing whatever to do with consensus. Consensus is the business of politics. Science, on the contrary, requires only one investigator who happens to be right, which means that he or she has results that are verifiable by reference to the real world. In science consensus is irrelevant. What is relevant is reproducible results. The greatest scientists in history are great precisely because they broke with the consensus. There is no such thing as consensus science. If it's consensus, it isn't science. If it's science, it isn't consensus. Period.
I would remind you to notice where the claim of consensus is invoked. Consensus is invoked only in situations where the science is not solid enough. Nobody says the consensus of scientists agrees that E=mc2. Nobody says the consensus is that the sun is 93 million miles away. It would never occur to anyone to speak that way.
People often assume that science is only about empirical research - that it's merely about facts and figures, which happens to be nowhere near the truth. Facts are the fundamental building blocks of science, but bringing those facts together to have an insight of a certain phenomenon requires a rational, conscientious and creative mind. It's only through rigorous analysis and observation, as well as, creative contemplation, of the empirical evidence, i.e. facts, discovered through decades of research, that we can understand a certain phenomenon. Science cannot exist without empirical evidence, but evidence alone can't take science ahead and upwards, for that, we need some rather naΓ―ve and conscientious minds who can pierce through the evidence in order to have a practical insight of the big picture of a certain phenomenon. In short, there's more to science than facts and figures. Think of facts and figures as bricks and cement, and science or scientific understanding as a building. Without the vision of the architect, it's impossible to construct the building no matter how much bricks and cement you have.
