Scarcity

这本书最锋利处，在于它把'穷所以懒、忙所以乱'这类日常自责，重新归因为一种系统性的心理机制。它提出'带宽'概念——心智容量会因稀缺而缩水，让你既缺乏洞察力、又削弱执行控制力，于是越是缺钱缺时间，越容易做出不明智的选择，反而把处境推得更糟。读者读后'一身冷汗'，正源于此：许多失误并非不够谨慎，而是从心理过程根源处产生的偏见。它也因此引发争议：有人嫌它'一句话来回说一千遍'，有人却从中获得解释力与自我宽慰。它适合那些长期在deadline里冲刺、或困于收支紧绷的人——不是教你更努力地克制，而是让你看清：没有余闲本身，就在制造新的错误。

Sendhil Mullainathan is Professor of Economics at Harvard University. His real passion is behavioral economics, understanding what makes people tick - whether a senior executive in New York or a farmer in rural Tamil Nadu. He enjoys having written but is of a mixed mind about writing. He also occasionally enjoys doing: he helped co-found a non-profit to apply behavioral science (ideas42); and has worked in government. Much to the surprise of who know him well, he is a recipient of the MacArthur "genius" award. His hobbies include basketball, googling and fixing-up classic espresso machines. He also enjoys speaking about himself in the third person, which works well for bios but less well in daily life. Eldar Shafir is an American psychologist, and the author of Scarcity: Why Having Too Little Means So Much[1] (with Sendhil Mullainathan). He is the William Stewart Tod Professor of Psychology and Public Affairs at Princeton University Department of Psychology and the Woodrow Wilson School of Public and International Affairs. He is a Faculty Associate at the Institute for Quantitative Social Science at Harvard University. He is co-founder and Scientific Director at ideas42, a social-science R&D lab. His area of study is behavioral economics, that is, how the decisions people make affect their financial outcomes. His research has led him to the general conclusion that people often make inadvisable decisions on financial matters when they think they are being rational.
