这是你那个链接中的解释：
In the past, the main difference used to be the fields of interests. Sociologists studied "us", meaning primarily urban, western societies, whereas Anthropologists studied "them", meaning small tribes, colonized peoples and the like.

In our days, the lines between the disciplines has blurred. The main difference seems to be methodical, as sociologists prefer a quantitative approach, with tools like polls, statistics, mass interviews etc, where anthropologists prefer a qualitative approach, meaning in-depth interviews and participatory observation.

A short attempt at an answer to a complex question.

它说，对象区别（文明人和“不开化”人）是社会学和人类学过去的区别。今天已经不强调这种区别。今天是社会学注重量化方法，而人类学仍多是质的研究，深入的访问交谈和亲身参与得来的观察。那么我想，人类学这样的方法没有什么不可以用在社会学研究中的吧？那么我想，除非郭有别的关键的错误，还不可以说郭文是民科思路。
