多少发展数据算够?

内罗毕—科技的迅速进步极大地降低了收集数据的成本。太空、天空、实验室和实地传感器,以及新兴的众包机会和已得到广泛使用互联网和移动电话正在让人们获得从前无从获得的巨量信息。比如,如今非洲农村地区的小农轻点屏幕就可以了解天气预报和市场价格。

数据革命为改善个层面决策提供了巨大的潜力——不论是本地农民还是业务遍布全球的发展组织。但光是收集数据是不够的。还必须管理和评估信息——合理地完成这一任务可能远比收集数据更复杂、更昂贵。如果需要改善的决策从一开始无法得到合理的识别和分析,就极有可能让巨大的集体努力付诸东流或出现方向性错误。。

这一结论本身便是基于实证分析。比如,监测农业或环境管理项目能带来积极影响,这一观点的支持证据很弱。多个领域——包括环境政策、商业投资和网络安全——的量化决策分析表明,人们倾向于高估做出好决策所需要的数据量或误解需要的数据类型。

    Populist Plutocracy and the Future of America

    • In the first year of his presidency, Donald Trump has consistently sold out the blue-collar, socially conservative whites who brought him to power, while pursuing policies to enrich his fellow plutocrats. 

    • Sooner or later, Trump's core supporters will wake up to this fact, so it is worth asking how far he might go to keep them on his side.

    The Man Who Didn’t Save the World

    A Saudi prince has been revealed to be the buyer of Leonardo da Vinci's "Salvator Mundi," for which he spent $450.3 million. Had he given the money to the poor, as the subject of the painting instructed another rich man, he could have restored eyesight to nine million people, or enabled 13 million families to grow 50% more food.

    Two Myths About Automation

    While many people believe that technological progress and job destruction are accelerating dramatically, there is no evidence of either trend. In reality, total factor productivity, the best summary measure of the pace of technical change, has been stagnating since 2005 in the US and across the advanced-country world.

    The Hungarian Government’s Failed Campaign of Lies

    The Hungarian government has released the results of its "national consultation" on what it calls the "Soros Plan" to flood the country with Muslim migrants and refugees. But no such plan exists, only a taxpayer-funded propaganda campaign to help a corrupt administration deflect attention from its failure to fulfill Hungarians’ aspirations.
