Political psychology is an exciting field because it is directly and immediately relevant to current events. This feature of the field is also a drawback because it can unintentionally limit the knowledge of the field to current events and prevent the development of generalizable knowledge. We discuss how using representative samples, representative political systems, and representative stimuli can help political psychology develop a more comprehensive political psychology with knowledge that is both generalizable and relevant.
