More Sex is Safer Sex

Book excerpt: With his long-running 'Everyday Economics' column in Slate and his popular book, The Armchair Economist, Steven Landsburg has been leading the pack of economists who are transforming their science from a drab meditation on graphs and charts into a fascinating window on human nature. Now he's back and more provocative than ever with surprises on virtually every page. In More Sex is Safer Sex, Professor Landsburg offers readers a series of stimulating discussions that all flow from one unsettling fact. Combining the rational decisions of each of us often produces an irrational result for all of us. Avoiding casual sex can actually encourage the spread of diseases. To solve population pressures, we need more people. In his tantalizing, entertaining narrative, Landsburg guides us through these shocking notions by the light of compelling logic and evidence and makes suggestions along the way: Why not charge juries if a convicted felon is exonerated? Why not let firemen keep the property they rescue? As entertaining as it is inflammatory, More Sex is Safer Sexwill make readers think about their decisions in unforgettable ways -- and spark debate over much that we all take for granted.
