As someone remarked once somewhere, it's much easier being stupid today than back in hunter-gatherer societies. Then again, the range and scope of things we have to engage today is far vaster. The world overwhelms us...
That said in regards to what Callan said, I am curious how do you people engage with run of the mill folks, being armed with all these factoids, theories and beliefs? A friend of mine (a dedicated Psych major in NA terms) uses the tools and techniques of her trade for making sales, but outside business she refrains from using it as best she can. She fails miserably of course, she routinely manipulates her girlfriend though she isn't aware of it. I haven't even clued her in on the side of Bakker, Watts and latest in NSC and CogSci, partly because I'm afraid of her skill with actual intent. I struggle myself not to be overly exploitative of people in the dark, to be honest.
