单选题 The report from the Bureau of Labor Statistics was just as gloomy as anticipated. Unemployment in January lumped to a 16-year high of 7.6 percent, as 598 000 jobs were slashed from US payrolls in the worst single-month decline since December, 1974. With 1.8 million jobs lost in the last three months, there is urgent desire to boost the economy as quickly as possible. But Washington would do well to take a deep breath before reacting to the grim numbers. Collectively, we rely on the unemployment figures and other statistics to frame our sense of reality. They are a vital part of an array of data that we use to assess if we're doing well or doing badly, and that in turn shapes government policies and corporate budgets and personal spending decisions. The problem is that the statistics aren't an objective measure of reality; they are simply a best approximation. Directionally, they capture the trends, but the idea that we know precisely how many are unemployed is a myth. That makes finding a solution all the more difficult. First, there is the way the data is assembled. The official unemployment rate is the product of a telephone survey of about 60 000 homes. There is another survey, sometimes referred to as the 'payroll survey, ' that assesses 400 000 businesses based on their reported payrolls. Both surveys have problems. The payroll survey can easily double-count someone: if you are one person with two jobs, you show up as two workers. The payroll survey also doesn't capture the number of self-employed, and so says little about how many people are generating an independent income. The household survey has a larger problem. When asked straightforwardly, people tend to lie or shade the truth when the subject is sex, money or employment. If you get a call and are asked if you're employed, and you say yes, you're employed. If you say no, however, it may surprise you to learn that you are only unemployed if you've been actively looking for work in the past four weeks; otherwise, you are 'marginally attached to the labor force' and not actually unemployed. The urge to quantify is embedded in our society. But the idea that statisticians can then capture an objective reality isn't just impossible. It also leads to serious misjudgments. Democrats and Republicans can and will take sides on a number of issues, but a more crucial concern is that both are basing major policy decisions on guesstimates rather than looking at the vast wealth of raw data with a critical eye and an open mind.

单选题 The most important divide in America today is class, not race, and the place where it matters most is in the home. Conservatives have been banging on about family breakdown for decades. Now one of the nation's most prominent liberal scholars has joined the chorus. Robert Putnam is a former dean of Harvard's Kennedy School of Government and the author of Bowling Alone (2000), an influential work that lamented the decline of social capital in America. In his new book, Our Kids, he describes the growing gulf between how the rich and the poor raise their children. Among the educated elite the traditional family is thriving: fewer than 10% of births to female college graduates are outside marriage—a figure that is barely higher than it was in 1970. In 2007 among women with just a high-school education, by contrast, 65% of births were non-marital. Race makes a difference: only 2% of births to white college graduates are out-of-wedlock, compared with 80% among African-Americans with no more than a high-school education, but neither of these figures has changed much since the 1970s. However, the non-marital birth proportion among high-school-educated whites has quadrupled, to 50%, and the same figure for college-educated blacks has fallen by a third, to 25%. Thus the class divide is growing even as the racial gap is shrinking. Upbringing affects opportunity. Upper-middle-class homes are not only richer (with two professional incomes) and more stable; they are also more nurturing. In the 1970s, there were practically no class differences in the amount of time that parents spent talking, reading and playing with toddlers. Now the children of college-educated parents receive 50% more of what Mr. Putnam calls 'Goodnight Moon' time (after a popular book for infants). Working-class parents, who have less spare capacity, are more likely to demand that their kids simply obey them. In the short run this saves time; in the long run it prevents the kids from learning to organize their own lives or think for themselves. Poor parenting is thus a barrier to social mobility, and is becoming more so as the world grows more complex and the rewards for superior cognitive skills increase. Stunningly, Mr. Putnam finds that family background is a better predictor of whether or not a child will graduate from university than 8th-grade test scores. Kids in the richest quarter with low test scores are as likely to make it through college as kids in the poorest quarter with high scores. Mr. Putnam suggests a grab-bag of policies to help poor kids reach their potential, such as raising subsidies for poor families, teaching them better parenting skills, improving nursery care and making after-school baseball clubs free. He urges all 50 states to experiment to find out what works. A problem this complex has no simple solution.
