I'll put you down as a skeptic of the Flynn Effect.
The US consistently ranks near the bottom in every measure of education. We're abysmal at science, we have no idea of geography, history, we can't read. 35% of adult males admitted in a Gallup(?) phone interview, admitted of their own free will, they didn't read a book last year. Probably proud of it. Probably say defiantly that they don't read the papers neither. Up near 50% allowed they'd read one book. And no, the Internet don't count. Lets avoid for the time being that pornography is the most accessed topic on the Web, and consider that reading a 400 page book on a single topic is not equivalent to reading 400 1 page articles on the same topic.
75% of us get most all of our news from the TV, the Internet is not putting newspapers out of business, TV is. And the infotainment shows that pass as news are absymal, see Limey's post.
We're stupid. And, pointing out that atleast some of us are smart doesn't help neither. We're a democracy, everybody votes. And most of us vote for someone who thinks like us. That's the worst thing we can do. I'm hoping to vote for someone who thinks better than I do. (by the way, I also hope for that in baseball) I think what H.L. Mencken said about 90 years ago is very close to the situation we have now. He said
"As democracy is perfected, the office represents, more closely, the inner soul of the people. We move toward a lofty ideal. On some great and glorious day, the plain folks of the land will reach their heart's desire at last, and the White House will be adorned by a downright moron.''
Mencken was, if anything, too limited in his choice of political office.
