Arnold Kling reviews Greg Ip's Foolproof: Why Safety Can Be Dangerous and How Danger Makes Us Safer. An excerpt:
One, which I call the engineers, seeks to use the maximum of our knowledge and ability to solve problems and make the world safer and more stable; the other, which I call the ecologists, regards such efforts with suspicion, because given the complexity and adaptability of people and the environment, they will always have unintended consequences that may be worse than the problem we are trying to solve.
As your faithful blogger loves to point out, the Law of Unintended Consequences reigns supreme. It is unbreakable.
