The first step is admitting there’s a problem.
You didn’t define the problem. You pointed out that 10% of professors in the humanities and social sciences are Republican, but you didn’t say why that is a problem. Is it a problem because that number isn’t 0% or because it isn’t higher?
Stephen Colbert famously pointed out that “reality has a well-known liberal bias.” When he said that right in front of George W. Bush, was that an echo chamber? If he’s right, and reality does have a liberal bias, doesn’t it make sense that professors who ostensibly educate students about reality would also have a liberal bias?
If one side of an argument is right and the other is wrong (let’s take global warming), and if the left has sided with the scientifically factual view, but the right has sided with the non-scientific, counterfactual view, does the right really deserve to be represented in a discussion in higher education? Can they not simply be quickly discredited so the discussion can progress to science and fact and how to address this monumental problem in a reasonable fashion? Should professors, in an effort to be unbiased, talk about creationism in an evolutionary biology class or even a medical ethics class, or should the students get to learn the science and rational thinking they signed up to learn?
Give me a break. The problem isn’t professors or higher education. The problem is just that some people are wrong. If you believe in creationism, you’re wrong. If you deny global warming, you’re wrong. If you think there is no gender gap in media representation, you’re wrong. If you think 2000s hip hop was as good as 1990s hip hop, you’re wrong. I believe people are entitled to be wrong. If you want to believe in something ridiculous, go for it. But, you don’t get to waste every student’s time at college with your wrongness and backward thinking. Professors enjoy status, prestige, and a good income and, with that, they divest themselves of an entitlement to be wrong. Their job is to promulgate facts, to teach critical thinking and reason. It makes sense, then, if reality has a liberal bias, that few professors would be Republican. My only question is, what are those 10% thinking?
