All things considered, science is the best means of understanding almost everything around us. It works well on the human scale and stands as a stark counter-point to beliefs that by their very nature refute the notion of evidence. And I would be the last person to attack people encouraging the rest of us to use our ability to be rational, thereby defending the value and the necessity of science. But I will lift a querying hand when the notion of ‘science’ is held to be immutable, because ‘science’ as such does not exist. Science is a process to be sure, a way of thinking, but what science is above all is that which scientists do, and alas, scientists are people, too. As potentially fallible, irrational, biased, greedy, in short, as flawed, as the rest of us. So, by all means defend science as a process. But don’t confuse it with the very human endeavor of science as a profession. Because they’re not the same thing. And this is why when some guy in a white lab-coat says ‘you can trust me, I’m a scientist,’ best take it with a big bucket of salt, and then say ‘Fine, now show me the evidence and more to the point, show me how you got to it.
