This is a shit take. The meme is showing two different stereotypes of college freshman. There is not a qualitative difference between the "hard" sciences and the others; the biologists climatologists and psychologists I've known all adhere to the same scientific method and mathematical rigor I learned getting my handful of grad and postgrad degrees in physics math and compsci. The only real difference I've seen is that "soft" sciences tend to work on problems with more stochastic moving parts, making them harder to understand on average. They're not easier, you're just ignorant of the complexity and too arrogant to consider the expertise and accomplishments of others.
