As the domains of social and personality psychological science undergo marked changes in their approach to research (e.g., open science practices, and addressing the replication crisis), it is important to undertake a full review of the tools and measures that we have at our disposal.In addition, the growing sense of political and ideological polarization in contemporary western democracies necessitates a coherent and internally consistent approach to studying politically and ideologically sensitive topics. This paper explores the measurement and study of such topics, and posits that claims about (a)symmetries between ideological partisans may be rooted in different measurement approaches. A more consistent and ecologically valid approach to studying partisan engagement with political topics is advocated, focusing on situational responses to ideologically salient scenarios, rather than placing our focus on results from decontextualized self-report individual difference measures. Suggestions for broader debiasing research reforms are also explored.
Ideological measurement in social and political psychologyThe landscape of social psychology is currently undergoing some stark changes.Emerging practices to address the 'replication crisis' (Brandt et al., 2014;Lindsay, 2015) and the advent of increasingly open research practices, such as data-and materials-sharing, protocol and analytic pre-registration, and the peer-review of research plans before data are collected and results are known (Chambers, 2018;van't Veer & Giner-Sorolla, 2016; have led the field to consider some of the questionable research practices that have historically persisted in some spheres .Although these movements are clearly positive for the state of our science, they focus only on the higher-level processes associated with potential biases in research design and execution. This paper begins by looking at the 'nuts and bolts' of social and personality psychological research, as applied in the political domain, to explore potential sources of ideological bias in the conceptualization and interpretation of ideologies. That is, there is an argument to be made that our current approaches to studying similarities and differences between those from competing political or ideological persuasions (from here, these similarities and differences are referred to as 'political/ideological (a)symmetries') may contain epistemic biases on the part of the field in the aggregate. In doing so, a critique of commonly used measurement tools in the political psychology domain is offered, and further suggestions for alternative approaches to researching ideological (a)symmetries are offered that are consistent with the continuing the recent advances in social psychological research.
