What is the difference that ethmomethodologists see between conventional sociologists and the man in the street?

Ethnomethodologists see little difference between conventional sociologists and the man in the street; they argue that the methods employed by sociologists in their research are basically similar to those used by members of society in their everyday lives.

Members employing the documentary method are constantly theorizing, drawing relationships between activities and making the social world appear orderly and systematic. They then treat the social world as if it had an objective reality separate from them.
