In an era where online interactions can be both motivational and toxic, researchers from the Computational Social Science Lab (CSSLab) at the University of Pennsylvania are interested in what encourages prosocial behavior — acts of kindness, support, and cooperation — on social media.

Climate change is one of the most pressing challenges of our time, demanding urgent and effective action to mitigate its severe impacts. One barrier to effective climate change action is its polarizing nature largely driven by the media, as people prefer to consume news that aligns with their political beliefs. This tendency is especially strong among climate skeptics, who are more inclined to seek information that reinforces their views on climate change. In this context, communication—especially on social media—plays a crucial role in bridging cross-partisan boundaries. However, meaningful dialogue may be hampered if individuals do not believe these interactions will be effective.

Early advocates of social media believed that the creation of these platforms would lead to positive outcomes. When Facebook was launched in 2004, it was praised for its ability to “connect the entire world.” In hindsight, many of these ideals were optimistic at their time as social media platforms are often criticized for spreading hate and misinformation.
