This paper is an essay on nonrespondent bias in statistical random sampling surveys. In particular, it focuses on the personalities of respondents and nonrespondents in survey cooperation. First, I review previous relevant research on nonrespondent bias and outline the main points of the nonrespondent bias problem. Next, focusing on items related to interpersonal trust, I analyze personality differences between cooperative and non-cooperative respondents using time series data from the Japanese National Character Survey and its related surveys. I then present rules of thumb that may be useful for survey researchers dealing with nonrespondent bias. Finally, I discuss future issues. Particular mention will be made of social disparities in electoral voting and polling, i.e., people who tend to drop out of electoral voting and polling.
