Middle alternatives revisited: how the neither/nor response acts as a ‘face-saving’ way of saying ‘I don’t know’. Southampton, GB, Southampton Statistical Sciences Research Institute, 25pp.

In this paper, we use follow-up probes administered to respondents who initially select the mid-point to determine whether they selected this alternative in order to indicate opinion neutrality, or to indicate that they do not have an opinion on the issue. We find the vast majority of responses turn out to be what we term ‘face-saving don’t knows’ and that reallocating these responses from the mid-point to the don’t know category significantly alters descriptive and multivariate inferences. Our findings have important implications for the design and analysis of bipolar ratings scales.
