A research agenda for encouraging prosocial behaviour on social media.

Many studies examine antisocial behaviours on social media-such as sharing misinformation or producing hate speech-but far fewer examine how platforms can incentivize more prosocial behaviour. We identify several ways in which social media platforms currently enable such behaviour, including (1) connecting new communities, (2) enabling collective problem-solving and (3) expanding the boundaries of philanthropy. However, we also discuss how some of the factors that enable prosocial behaviour can also empower malicious actors-as well as the challenge of creating prosocial behaviour that is sustainable and impactful offline.

Interventions to reduce partisan animosity.

Rising partisan animosity is associated with a reduction in support for democracy and an increase in support for political violence. Here we provide a multi-level review of interventions designed to reduce partisan animosity, which we define as negative thoughts, feelings and behaviours towards a political outgroup. We introduce the TRI framework to capture three levels of intervention-thoughts (correcting misconceptions and highlighting commonalities), relationships (building dialogue skills and fostering positive contact) and institutions (changing public discourse and transforming political structures)-and connect these levels by highlighting the importance of motivation and mobilization.
