副標題：Adults in rich countries are less literate than they were a decade?ago. That requires attention主要說在富裕國家成年人數學和閱讀能力不如小學生，并建議政府應該改善兒童課程和成人教育系統來應對
研究發現成年人在數學和閱讀方面不比小學生好：Data?released on December 10th by the OECD, a club of mostly rich?countries......The latest tests were carried out in 31 rich countries......They suggest that a fifth of adults do no better in maths and reading than might be expected of a primary school child大人不如小孩系列
這樣可能的原因：人口變化New immigrants often struggle with a new language. The native-born have ageing brains.社交媒體削弱敏銳度. Some speculate that Netflix, video games and social media are sapping acuity. 教育和培訓系統失敗It is just as likely that education and training systems have misfired.竟然沒有提到短視頻影響？？？
導致技能最高和最低人之間差距拉大：In many countries the gap in ability between the highest- and lowest-skilled grown-ups is widening (not because smarty-pants are doing better, but because the least able are doing worse).這個也很反直覺，那就是有些人保持自己不提升，結果在社會上也是頂尖的存在，因為下面沒有追趕上來的人，而是都掉隊了
怎么辦？改善兒童課程Improving lessons for children is the surest way of creating more capable grown-ups; governments ought to start there.改善成人教育系統These hand dropouts second chances; they also serve people who change careers and help migrants integrate.
