Toward the end of a long profile of sociologist Matthew Desmond is an interesting section regarding ethnographic methods:

Desmond has done an especially good job spelling out precisely how he went about his research and verified his findings, says Klinenberg. At the start of Evicted, an author’s note states that most of the events in the book took place between May 2008 and December 2009. Except where it says otherwise in the notes, Desmond writes, all events that happened between those dates were observed firsthand. Every quotation was “captured by a digital recorder or copied from official documents,” he adds. He also hired a fact-checker who corroborated the book by combing public records, conducting some 30 interviews, and asking him to produce field notes that verified a randomly selected 10 percent of its pages.

Desmond has been equally fastidious about taking himself out of the text. Unlike many ethnographic studies, including Goffman’s, his avoids the first person. He wants readers to react directly to the people in Evicted. “Ethnography often provokes very strong feelings,” he says. “So I wanted the book to do that. But not about me.”

Ethnographers should be more skeptical about their data, Desmond believes. In his fieldwork, for example, he saw women getting evicted at higher rates than men. But when he crunched the data, analyzing hundreds of thousands of court records, it turned out that was only the case in predominantly black and Latino neighborhoods. Women in white neighborhoods were not evicted at higher rates than men. The field had told him a half-truth.

Still, beyond acknowledging that the reception of Goffman’s book shaped his fact-checking, he will say nothing about the controversy. Even an old journalism trick — letting a silence linger, in the hope that an interviewee will fill it — fails to wring a quote from him. “This is such a good technique,” he says after a few seconds, “where you just kind of let the person talk.” Then he sips his Diet Coke, waiting for the next question.

This gets at some basic questions about what ethnography is. Should it be participant observation with a reflexive and involved researcher? Letting the research subjects speak for themselves with minimal interpretation? Should it involve fact-checking and verifying data? Each of these could have their merit and sociologists pursue different approaches. Contrasting the last two, for example, how people describe their own circumstances and understanding could be very important even if what is reported is not necessarily true. On the other hand, more and more ethnographies involve reflexive commentary from the researcher on how their presence and personal characteristics influenced the data collection and inteprretation.

It sounds to me like Desmond is doing some mixed methods work: starting with ethnographic data that he directly observes but then using secondary analysis (in the example above, using official records) to better understand both the micro level that he observed as well as the broader patterns. This means more work for each study but also more comprehensive data.
