Smart people don't like the idea of intelligence. Just mention 'IQ' in polite company, and you'll be informed that IQ tests don't measure anything real, and only reflect how good you are at doing IQ tests.
But anyone who makes these arguments simply hasn't seen the scientific evidence. The research shows that intelligence test scores are meaningful and useful; that they relate to education, occupation, and even health; that they are genetically influenced; and that they are Linked to measures of the brain, including its size.
Intelligence: All That Matters is an entertaining introduction to intelligence and IQ research, covering what it is and how it's measured, its biology, why it matters, and how we might improve it. The book engages head-on with many of the criticisms of IQ testing, but also makes a positive case for intelligence research, describing the potential benefits for society that a better understanding of intelligence can bring.
