What are five specific limitations of focus groups?

●   “Polarization effect” exists whereby attitudes become more extreme after group discussion.
●   Only one or a few topics can be discussed in a focus group session.
●   A moderator may unknowingly limit open, free expression of group members.
●   Focus groups may produce groupthink.
●   It is not clear whom the members of the focus group are representing—themselves, social groups, or their membership to the focus group.
●   Focus group participants produce fewer ideas than individual interviews do.
●   Focus group studies rarely report all the details of study design/procedure.
●   Researchers cannot reconcile the differences that arise between individual-only and focus group-context responses.
