The algorithm that works best in the liberal arts is "guess what the teacher wants to hear and say it."
The horrible truth is that this is an unreasonably effective algorithm for functioning in management. At worst, it's used by scam artists like Madoff and Ken Lay. Many executives have left a trail of destruction, moving from one company to another just before reality sets in.
If there's any attribute that will cause mankind to end up like the dinosaurs, it's like this. It's got everything to do with our inability to deal with problems like global warming and it drives the everyday mediocrity that drags us down.
Back in college I remember some of the humanities profs were known to be liberal and others were conservative. Students who had different politics frequently believed they weren't graded fairly.
The mediocracy hates STEM and has waged a war against math because, often, we can say results in STEM are objectively right or wrong.
For instance, one time I pointed out an error that a math prof made on the board and he was happy to be corrected -- it's a bit of evidence that he's succeeding at his job. But after class, a student told me he was shocked that I'd been arrogant enough to think the teacher was wrong!
On the other hand, if you don't agree with what a humanist says about Shakespeare, for instance, she might reply that "different people can believe different things" or she can be bullheaded and not admit the subjective element.
I remember having a English teacher in high school who was the most respected, but I couldn't get better than a "D" in her class because she thought I couldn't write.
A few years later I had a strech when I got most of my income from writing and copy editing so there.
