In observational research, was it possible or reasonable to use multiple observers or teams, diverse in age, gender, or ethnicity? Were observational findings cross-checked with other researchers? Were negative cases sought out to test emergent propositions?

Were the research setting and findings described in such a way that the reader can “see”

and “feel” what it was like there? Was reliability addressed by making observations in various settings, at various times of the day, days of the week, and months of the year?
