The Dumbest Generation?

,
Every generation thinks its teenagers are the worst.
The old have been wringing their hands about the young's cultural wastelands and ignorance of history at least since admirers of Sophocles and Aeschylus bemoaned the popularity of Aristophanes ("The Frogs," for Zeussakes?!) as leading to the end of (Greek) civilization as they knew it. The Civil War generation was aghast at the lurid dime novels of the late 1800s. Victorian scholars considered Dickens, that plot-loving, sentimental ("A Christmas Carol") favorite, a lightweight compared with other authors of the time. Civilization, and culture high and low, survived it all.
Is today's generation really the dumbest?
