How smart are you? If that question doesnt spark a dozen more questions in your mind (like What do you mean by smart, How do I measure it and Whs asking?), then The Mismeasure of Man, Stephen Jay Goulds masterful demolition of the IQ industry, should be required reading. Goulds brilliant, funny, engaging prose dissects the motivations behind those who would judge intelligence, and hence worth, by cranial size, convolutions, or score on extremely narrow tests. How did scientists decide that intelligence was unipolar and quantifiable?
