So why do we go through more schooling after high school? Does college actually make you smarter or is it just a credential to make you look employable? According to sociologists Richard Arum and Josipa Roksa, 36 percent of students had no gains in reasoning or writing skills after four years of college. I find it interesting that it's possible to cruise through four years of higher level education and walk away with just some good memories. We're all paying a substantial amount of money for college, but if nearly 40 percent of students today aren't learning anything, why are they doing it?
Now on the contrary, chapter 9 goes over how people who attend school have more synapses which are neural connections and are also more likely to have a higher IQ. I'm sure this is true for the majority of students. Another question having to do with correlation vs. causation that was raised in my head was are students getting higher IQ's from attending college or are students who have high IQ's just more likely to attend college? To answer this, according to the book, students who drop out of school end up with lower IQ's than students who don't even if they both start with the same IQ.
So is it worth it? I would say for most people yes. It gives you certain problem solving experiences you can't get anywhere else.
