This article argues that in order to adequately comprehend and explain change, the field needs to engage more completely with the challenges of researching change over time, and ground the theorizing of change more firmly in empirical research. The goal of this article is to foster a more concerted discussion on these issues that will hopefully move research forward. The first part of the article reviews the breadth and diversity of existing empirical approaches to comprehending change over time across the field.
