A new paper analyzes the “production-consumption gap” on social media, where a small subset of users produce most of the content, and considers its implications for the study of phenomena such as political polarization, and for the design of policy interventions. Prithvi Iyer considers the results:
What a New Study Reveals About the Production-Consumption Gap on Social Media | TechPolicy.Press
Prithvi Iyer considers new research on how online content reveals the tip of the iceberg, leading to incorrect inferences about online public opinion.
