Question

The sociologist Mitch Duneier wrote his ethnography, Sidewalk, about street vendors in New York City’s Greenwich Village. While writing the book, Duneier was particularly concerned that the people he was studying would alter their behavior when he was present, especially since his background was very different from theirs. What do sociologists call this problem?

Answer 1

The interference in the observation participation

Step-by-step explanation:

When an ethnographer starts a social study he or she need to observe as much as he or she can the culture, the people, the common and uncommon situations. To collect as much information as they can. Of course at the begging the new group will react strange because there is a new member, but by passing the time, they used to the presence of this member and the behavior returns to the "normal" state.
