# The intelligence of humans is rapidly declining, whether measured by SAT scores,<ref>''See, e.g.'', David G. Savage, "The Long Decline in SAT Scores," Educational Leadership 290 (Jan. 1978). [http://www.ascd.org/ASCD/pdf/journals/ed_lead/el_197801_savage.pdf]</ref> music, personal letters,<ref>E.g., Civil War letters.</ref> quality of political debates,<ref>E.g., contrast the Lincoln-Douglas debates with debates today.</ref> the quality of news articles,<ref>''The Federalist'' was written for the newspaper audience in the late 1780s, but is far too intellectual for newspapers today.</ref> and many other measures. This means that if one goes back far enough, intelligence will end up reaching ridiculously high, if humans were supposedly hundreds of thousands of years old. There is also scientific evidence that there were more geniuses around a thousand years ago and intelligence has tapered off since then.
