‘Crowding out’ the competition: Study reveals surprising livestream chatting and tipping behavior

A new study by the University of Notre Dame found that viewers tend to tip less and chat more when they see others receiving higher tips, leading to a 'crowding-out' effect. This behavior is driven by the pursuit of social status and can be mitigated by splitting crowded livestreams into smaller virtual sessions.
