Why do liberals hate science?
The Left has long claimed that it has something of a monopoly on scientific expertise. For instance, long before Al Gore started making millions by claiming that anyone who disagreed with his apocalyptic prophecies was “anti-science,” there were the “scientific socialists.” “Social engineer” is now rightly seen as a term of scorn and derision, but it was once a label that progressive eggheads eagerly accepted.
Masking opinions in a white smock is a brilliant, albeit infuriating and shabby, rhetorical tactic. As the late Daniel Patrick Moynihan famously said, “Everyone is entitled to his own opinion, but not his own facts.” Science is the language of facts, and when people pretend to be speaking it, they’re not only claiming that their preferences are more than mere opinions, they’re also insinuating that anyone who disagrees is a fool or a zealot for objecting to “settled science.”
Put aside the fact that there is no such thing as settled science. Scientists are constantly questioning their understanding of things; that is what science does. All the great scientists of history are justly famous for overturning the assumptions of their fields. The real problem is that in politics, invocations of science are very often marketing techniques masquerading as appeals to irrefutable authority. In an increasingly secular society, having science on your side is better than having God on your side – at least in an argument.
I’m not saying that you can’t have science in your corner, or that lawmakers shouldn’t look to science when making policy. (Legislation that rejects the existence of gravity makes for very silly laws indeed.) But the real intent behind so many claims to “settled science” is to avoid having to make your case. It’s an undemocratic technique for delegitimizing opposing views and saying “shut up” to dissenters.
For example, even if the existence of global warming is “settled,” the policies for how to best respond to it are not. But in the political debates about climate change, activists say that their climatological claims are irrefutable and so are their preferred remedies.
