Here at the Belief Systems Lab we study ideologies and worldviews from several angles. A full list of lab publications is on the publications page.
- Worldview Conflict
- Social Status and Power
- Morality and Moralization
- Improving Psychological Science
Contrary to some scholars’ expectations (Bell, 1960), the end of ideology has yet to arrive. Conflicts over political, religious, and moral disagreements are a defining characteristic of our time. In the Netherlands, Europe, and the United States, these conflicts arise over political and religious issues, such as the role of government in healthcare, gun control, immigration, and abortion. Our research tries to understand the root causes of these ideological conflicts by studying how political, religious, and moral beliefs structure people’s attitudes and behaviors and provide people with a sense of meaning.
1. Worldview Conflict
If we take psychological findings about political and religious belief systems at face value we predict that people with more traditional belief systems are more likely to be prejudiced, intolerant, and sensitive to group boundaries compared to people with more liberal or progressive belief systems. This view is consistent with the idea that conservatives tend to be higher on need for closure and more sensitive to threat compared to liberals. We have challenged this prevailing view with our work on the ideological-conflict hypothesis (Brandt et al., 2014). We find that both liberals and conservatives will be equally intolerant of groups with differing political worldviews (Wetherell, Brandt, & Reyna, 2013). The effect has recently been extended to religious fundamentalism (Brandt & van Tongeren, in press). The impact of ideology is so strong that we find it can cause intolerance in people who profess to be open to experiences (Brandt et al, 2015). This challenges the traditional social psychological view on both prejudice and political polarization, suggesting that our current models of belief systems are incomplete.

2. System justification & the status quo
People have a pervasive tendency to support the status quo, a finding that is consistent across psychological subdisciplines including judgment and decision making, social psychology, and political psychology. In the lab, we are interested in this from two directions. First, we are interesting in how power and social status predict support for the status quo (Brandt, 2013). Currently, we are building on this work by conducting a large and international study with over 60 collaborators from around the world that will test a number of potential moderators of the association between status, power, and legitimacy among individuals and between countries. Second, we are interested in the cognitive processes that bolster such status quo biases. Currently, we are trying to understand how memory retrieval processes might underly support for the status quo. In general, the goal is understand the precise processes, so that these biases can be reduced.

3. Morality and Moralization
Moral and immoral events are common and play an important role in people’s emotional lives and in their sense of wellbeing and belonging (Hofman, Wisneski, Brandt & Skitka, 2014). How do people come to hold onto their moral beliefs in the first place and why are they such a powerful factor? We have studied this question by focusing on moralization, which is when an attitude, idea, or behavior acquires moral relevance over time (Brandt, Wisneski, & Skitka, 2015) and by trying to understand the precise mechanisms linking disgust with harsher moral judgments.

4. Improving Psychological Science
Psychological science, and social psychology in particular, has faced a number of crises over the last several years. We won’t always live up to our high expectations for a solid science, but the best response is to try our best to do better in terms of the replicability of our results, the robustness of our methods, and the quality of our theories.
