I discuss it in my science class. I discuss why it may be true, but it isn't science.
Science doesn't deal with right vs. wrong or good vs. bad, either. That doesn't mean those concepts don't exist; it just means they aren't part of science.
I didn't learn much, if anything, about "least common denominator" in English class, but that didn't make it a less valid topic in math class.
I seem to recall touching on these in Science (Sociology) class. The "irrational roots of rationality" of Max Weber pondered why we do the "right" thing.
