We introduced the podcast with a two-part series with Dr. Peter H. Ditto, Professor of Psychology & Social Behavior, telling us about โPolitical Sectarianismโ explaining how our divide goes beyond policy preferences and ideas, arguing that American political partisans are bonded by something that looks more like religious faith where “our” side is morally superior to the other.
The โpolitical sectarianismโ research examined a vast array of related research, including research that found that tweets with negative emotion got more engagement, more reactions and reshares, and further, that tweets with moral language got even more engagement.
We talked to Dr. Kurt Gray, Professor of Psychology and Neuroscience, about research showing how virality metrics, simply showing how popular a message is, can cause moral panics that in turn result in expressions of outrage.
The research we talk about in this episode builds on all this. The paper is titled: Out-group animosity drives engagement on social media
In this episode you will learn about negative affect language, moral language, negativity bias, social identity theory, and much more.
You really want to listen to this conversation. Itโs so good that this will be a two-part series.
