It was a treatise on research methodology, describing how to do cross-cultural studies of morals and moral behavior.

这是一篇关于研究方法论论文，描述了何进道德和道德跨文化研究。

Why do we study sleep? Sleep is something that has really been an unexplored topic cross-culturally.

我们何要研究睡眠？睡眠这个题还没有以跨文化方式研究过。

And if everything looks promising, then it will justify trying to build a sleep lab and study sleep across cultures that way.

果各种迹象看起来都比较好，那就可以有理由建立一个睡眠实验室，以那种方式研究跨文化睡眠状况。

This is not entirely true though and we know that through some very interesting cross-cultural research that compares these biases across different countries, in this study between the United States and India.

但这并不完全正确， 我们知道，通过一些非常有趣跨文化研究， 比较了不同国家之间这些偏见，在这项研究中， 美国和印度之间存在偏见。
