Primacy Effects and Voting Methods (Literature Review)

Abstract

The primacy effect has long been considered a decisive factor in determining election outcomes and has consequently developed a robust literature dedicated to studying it in different scenarios and contexts. However, existing research has offered limited insight into how the choice of voting method, particularly by-mail voting, may infl uence its impact on elections by altering how and when voters participate. This article fi rst reviews why the primacy effect exists, how researchers identify its infl uence, and its overall impact on election outcomes. It then discusses why the use of by-mail voting should be expected to alter the primacy effect, and analyzes two works where this relationship has been explored. Their results highlight several of the issues faced when trying to examine this relationship, but also indicate that further study is warranted and likely to be fruitful.
