This seems to be true of most people, and it's very sad. It's not the memorized facts of science that are important in everyday life, but rather the worldview, the way of looking at evidence and analyzing cause and effect relationships.
I learned about that in logic class in college, plus math class and philosophy. It isn't just science that includes such skills.
But, you make a good point. We should use what we learn in science class about analysis etc.
That is largely what dissection labs etc. are for I am sure.
