Q1.  According to a study by researchers at four British universities, for each I5-point increase in IQ, the likelihood of getting married increases by around 35% for a man but decreases by around 58% for a woman. Why?

In the original version of this question we misstated a statistic. This was caused by reproducing an error that appeared in several media summaries of the study. We are grateful to one of our contestants, Xinyi Zhang, who helped us to see (with humility and courtesy) why we should take more care to check our sources. We corrected the text on 4 April. Happily, the correction does not in any way alter the thrust of the question.

根据英国四所大学的一项研究，智商每提高 15 分，男性结婚的可能性就会增加 35%，而女性结婚的可能性则会降低 58% 。为什么？

在这个问题的原始版本中，我们错误地陈述了一项统计数据。这是由于复制了多家媒体研究摘要中出现的错误而造成的。感谢我们的一位参赛者Xinyi Zhang，帮助我们发现了这个问题。之后我们将会更加仔细地检查消息来源。现在我们于 4 月 4 日更正了文本。幸好，此次更正并没有以任何方式改变问题的主旨。
