Case studies of clear emergencies lack variability needed for causal comparisons.

Evidence

As a case study, the London bombings analysis was limited in its ability to provide evidence about the role of common fate and shared social identity. In the first place, due to the difficulty of getting people to talk about such distressing experiences, the interview part of the dataset was small. Second, the dataset as a whole was low in variability (for example, reports of help were overwhelming), which meant that it was difficult to make comparisons and show the effects associated with different levels of key variables. What was needed to provide a better examination of the social identity approach to mass emergency behaviour was a study using a comparative design. — John Drury, The role of social identity processes…, 76
