Speakout Advanced p 86. BBC Documentary - Stupidity. Extra Listening

This documentary raises questions about what 'stupid' really is and who this idea of stupidity can apply to. Stupidity may not be exactly what you once thought it was.
It also tells us the history of the word "moron", the difference between stupid, moron, smart, intelligent, genius and questions the regular practice of classifying peoples intelligence through standardized IQ tests.

Albert Einstein said:
"Only two things are infinite the universe and stupidity and I am not sure about the former."
