Despite these problems, however, enriched asking can be used to conduct important research,
as was demonstrated by Stephen Ansolabehere and Eitan Hersh(2012) in their research on voting patterns in the United States.
In their paper, Ansolabehere and Hersh go through a number of steps to check
the results of these two steps- even though some of them are proprietary- and these checks might be helpful for other researchers wishing to link survey data to black-box big data sources.
