Culturally, yes, we are getting dumber. Language and other arts are being tossed wayside for the sake of "right now" entertainment, but by and large the human race is not any more stupid than any prior generations. You really have to look at what society pushes on its offspring as the leading factor in our decline. Whereas it was once an honor to attend a university and be considered a scholar, it is now this expected experience that takes a backseat to being an athlete or getting your five minutes of fame on youtube or american idol. One day our increasingly impetuous behavior will lead to our own demise as we develop better and faster ways to destroy ourselves, that's why it's important to look at yourself and evaluate your own actions and ensure that your children are equipped with the necessary tools to appreciate concepts like honor, hard work, and respect.
