Abstract
It is an important and controversial topic whether voters can make reasonable choices or not. In this paper, I review the recent advancements on this topic in voting behavior. I first review literature until the late 90s and confirm the ignorance of voters and irrationality of their decision, which was presented in the American Voter, has been refuted. Next, I review the recent revision of voters' rationality based on the advancements of psychological research. In addition, I also review the applications of biological and neural sciences, which provides the scientific explanation of voters' emotional responses. Finally, I summarize the characteristics of the recent research movements and discuss the future of this research field.
