Steve studies intergroup conflict, the spread of (mis)information, and how these topics interact with digital technologies, such as social media and artificial intelligence.
Some of his work has focused on how social media incentivizes the creation of polarizing content, why we believe and spread misinformation, why people share content that they say they do not like, and the impact of unfollowing hyperpartisan influencers. He has also explored the relationship between social media usage and vaccine hesitancy or the psychological effects of attending live theatre. His current work focuses on how the impact of social media differs around the globe, and how we can use recent advances in artificial intelligence to improve methods in psychological science.
