“After all, your chances of winning a lottery and of affecting an election are pretty similar. From a financial perspective, playing the lottery is a bad investment. But it's fun and relatively cheap: for the price of a ticket, you buy the right to fantasize how you'd spend the winnings - much as you get to fantasize that your vote will have some impact on policy.”

“Social scientists sometimes talk about the concept of "identity". It is the idea that you have a particular vision of the kind of person you are, and you feel awful when you do things that are out of line with that vision.”

“Information is a beacon, a cudgel, an olive branch, a deterrent--all depending on who wields it and how.”

“When the solution to a given problem doesn’t lay right before our eyes, it is easy to assume that no solution exists. But history has shown again and again that such assumptions are wrong. This is not to say the world is perfect. Nor that all progress is always good. Even widespread societal gains inevitably produce losses for some people. That’s why the economist Joseph Schumpeter referred to capitalism as “creative destruction.” But humankind has a great capacity for finding technological solutions to seemingly intractable problems, and this will likely be the case for global warming. It isn’t that the problem isn’t potentially large. It’s just that human ingenuity—when given proper incentives—is bound to be larger. Even more encouraging, technological fixes are often far simpler, and therefore cheaper, than the doomsayers could have imagined. Indeed, in the final chapter of this book we’ll meet a band of renegade engineers who have developed not one but three global-warming fixes, any of which could be bought for less than the annual sales tally of all the Thoroughbred horses at Keeneland auction house in Kentucky.”

“In the United States especially, politics and economics don’t mix well. Politicians have all sorts of reasons to pass all sorts of laws that, as well-meaning as they may be, fail to account for the way real people respond to real-world incentives.”

“Morality, it could be argued, represents the way that people would like the world to work, wheareas economics represents how it actually does work.”

“But in both instances, the dissemination of the information diluted its power. As Supreme Court Justice Louis D. Brandeis once wrote, "Sunlight is said to be the best of disinfectants.”
