科学就是要允许犯错误

迄今为止,新的发现经常被当作是医学的主要目标。但是今天要取得新的发现实在是太容易了。任何人只要有一点点资金以及冰箱里存放着一些生物标本就能够取得数以千计的所谓的“发现”。

事实上,我们可以提出来的研究课题正以指数级的速度增长着。像一片指甲那么大的医学元件可以根据极少量的血测量出一个人一百万个不同的生物元素。由此马上可以提出一百万个研究课题。但是即便凭借正确的统计试验,几万生物元素会只是出于偶然而似乎显得很重要。然而其中只有很少一些是真正重要的。绝大部分这些初始的研究只会带来虚假的发现。

所以今天的主要课题是通过在不同的环境下重复这些“发现”来证明它们是否是正确的。需要有几个不同的研究小组运用通常的规则来一次又一次地证实它们是“成立”的。此外,所有的研究小组都必须同意不会只选择和报告那些看上去最吸引人的数据。如果只是加以选择地报告的话,那么我们最后只能得到由所有研究小组所发表的一长串完全错误的发现,而很少一些真正的成果却被淹没在这堆无法被重复的废物中。

    Angela Merkel’s Endgame?

    The collapse of coalition negotiations has left German Chancellor Angela Merkel facing a stark choice between forming a minority government or calling for a new election. But would a minority government necessarily be as bad as Germans have traditionally thought?

    Preparing for the Trump Trade Wars

    In the first 11 months of his presidency, Donald Trump has failed to back up his words – or tweets – with action on a variety of fronts. But the rest of the world's governments, and particularly those in Asia and Europe, would be mistaken to assume that he won't follow through on his promised "America First" trade agenda.

    The Platform Economy

    While developed countries in Europe, North America, and Asia are rapidly aging, emerging economies are predominantly youthful. Nigerian, Indonesian, and Vietnamese young people will shape global work trends at an increasingly rapid pace, bringing to bear their experience in dynamic informal markets on a tech-enabled gig economy.

    Profiles in Discouragement

    One day, the United States will turn the page on Donald Trump. But, as Americans prepare to observe their Thanksgiving holiday, they should reflect that their country's culture and global standing will never recover fully from the wounds that his presidency is inflicting on them.

    How Women Shape Coups

    In Zimbabwe, as in all coups, much behind-the-scenes plotting continues to take place in the aftermath of the military's overthrow of President Robert Mugabe. But who the eventual winners and losers are may depend, among other things, on the gender of the plotters.

    The Abnormality of Oil

    At the 2017 Abu Dhabi Petroleum Exhibition and Conference, the consensus among industry executives was that oil prices will still be around $60 per barrel in November 2018. But there is evidence to suggest that the uptick in global growth and developments in Saudi Arabia will push the price as high as $80 in the meantime.

    The Saudi Prince’s Dangerous War Games

    Saudi Arabia’s Crown Prince Mohammed bin Salman is working hard to consolidate power and establish his country as the Middle East’s only hegemon. But his efforts – which include an attempt to trigger a war between Israel and Hezbollah in Lebanon – increasingly look like the work of an immature gambler.
