Surveys and Nonresponse: Survey nonresponse often occurs when individuals refuse to answer questions. This is especially true for politically sensitive topics, such as placing politicians on an ideological scale.
The Problem: Why do people not respond? We suggest it might be related to their personality traits, specifically neuroticism — a tendency toward negative emotions and sensitivity to stress.
Our Findings: Using data from the 2014 Cooperative Congressional Election Study, we demonstrate that:
The New Model: We introduce a Bayesian hierarchical model for political science research. This statistical approach allows us to disentangle nonresponse caused by lack of information from that resulting from disincentives (like fear of error).
Implications: Our analysis shows these NA/DK answers are likely reflecting inhibited information gathering and decision-making processes among highly neurotic respondents, rather than simply a lack of knowledge.
