Austin Horng-En Wang (Political Science) published an article, "Who are the non-separable voters?," in Electoral Studies. In this article, Wang examines three competing hypotheses on the formation of non-separable preferences through a poll result in the 2021 Taiwan referendum. In this referendum, Taiwanese voters were motivated to form the non-separable preferences balancing environmental protection and power supply, and the two nationwide blackouts before the referendum enforced such a motivation. Results show that most of the non-separable voters cannot be explained by the theory-driven non-separable preferences; instead, their expressed preferences in the poll are closer to non-attitude. However, the proportion of non-attitude voters was large enough to alter the result of referendum.
