Here is a link to a video where young people are interviewed and asked very basic, almost tautological questions, such as “what country is the Queen of England from?” I think the video was before the death of the Queen, so no smart answer was given. People did not know. Nor did they know how many moons the Earth has, or what 7 + 7 + 7 equals. Yes, and they vote too. This cultural, if not dysgenic decline is alarming, and will doom civilisation if it progresses.
