The Illusion of Political Independence

This study discusses the asymmetric dominance effect in the context of political elections with third-party candidates. Animal and human research both show that the addition or removal of a third option influences choices between the remaining two options. The direction of sway created by the addition/removal of the 3rd option is context-dependent and unconsciously regulated. The results confirmed our hypotheses that both the timing and perceived viability of third-party candidates significantly influence voter preferences, with the strongest effects observed when third-party candidates remain present through election day. These findings suggest that the impact of third-party candidates extends beyond simple vote-splitting and is at least partly unconscious, though direct implicit measures were not employed. This study is situated in the context of U.S. presidential elections and focuses on moderate voters.
