If you must add the word “science” to your doings to make people believe it’s science…it ain’t science. Biology is biological science, but we usually say biology, and never “biology science”.
So why call sociology “social sciences”? And how about “political science”? Should that be politology?
Human psychology, of course, cannot possibly be science. Well, maybe for superhuman intellects. We can study worms pretty thoroughly. But encompassing the human mind using the human mind? I call “Gödel!” on that crap.
There’s really only one science. It’s called…Science. As a verb, it means employing the Scientific Method. As a noun, it’s all knowledge and understanding acquired through practice.
