Steven Landsburg's writings are living proof that economics need not be "the dismal science." Readers of The Armchair Economist and his columns in Slate magazine know that he can make economics not only fun but fascinating, as he searches for the reasons behind the odd facts we face in our daily lives. In More Sex Is Safer Sex, he brings his witty and razor-sharp analysis to the many ways that our individually rational decisions can combine into some truly weird collective results -- and he proposes hilarious and serious ways to fix just about everything.
When you stand up at the ballpark in order to see better, you make a rational decision. When everyone else does it too, the results, of course, are lousy. But this is just the tip of the iceberg of individual sanity and collective madness. Did you know that some people may actually increase the spread of sexually transmitted diseases when they avoid casual sex? Do you know why tall people earn more money than shorter competitors? (Hint: it isn't just unfair, unconscious prejudice.) Do you know why it makes no sense for you to give charitable donations to more than one organization?
Landsburg's solutions to the many ways that modern life is unfair or inefficient are both jaw-dropping and maddeningly defensible. We should encourage people to cut in line at water fountains on hot days. We should let firefighters keep any property they rescue from burning houses. We should encourage more people to act like Scrooge, because misers are just as generous as philanthropists.
Best of all are Landsburg's commonsense solutions to the political problems that plague our democracy. We should charge penalties to jurors if they convict a felon who is later exonerated. We should let everyone vote in two congressional districts: their own, and any other one of their choice. While we're at it, we should redraw the districts according to the alphabetical lists of all voters, rather than by geography. We should pay FDA commissioners with shares of pharmaceutical company stocks, and pay our president with a diversified portfolio of real estate from across the country.
Why do parents of sons stay married more often than parents who have only daughters? Why does early motherhood not only correlate with lower income, but actually cause it? Why do we execute murderers but not the authors of vicious computer viruses? The lesson of this fascinating, fun, and endlessly provocative book is twofold: many apparently very odd behaviors have logical explanations, and many apparently logical behaviors make no sense whatsoever.
为甚么我们总是一窝蜂去读畅销书?容我大段引述梁文道的解释,它至少不会比大部分畅销书更冗长: 「一本书不能有太多创见,以致于过度违背常识,才看几页就受不了。但是它却要显得有点智慧,将读者都明白甚至认同的道理用很聪明的方法包装一下,使得读者感到有那么一点...

评分在我看来第一章是最精彩的,以经济学的方法科学论证了禁欲教育所带来的出乎意料的糟糕效果,事情的真相常常事与愿违,后文中还指出了环保教育也可能陷入类似的误区。顺带嘲讽了宗教保守主义,毕竟宗教的本质是不断召唤过去来支持现在的合法性。其他章节也多有精彩的内容,其核...

其实这书不错 但是此类书都透着洋洋自得的气息
评分感觉一般!讲道理很勉强!
评分读懂不到百分之五十。
评分there is a major flaw of the theory: more sex, there will be more infection of HIV. Thus, the ratio of infection is indeed reduced by more sex, however, the result is still opposite of good.
