In this week's episode of Social Science Weekly, we delve into the world of Twitter with a study that scrutinizes the functioning and implications of Twitter's ranking algorithm. The episode is based on the paper titled "Twitter’s Algorithm: Amplifying Anger, Animosity, and Affective Polarization", from researchers Smitha Millia, Micah Carroll, Sashrika Pandey, Yike Wang, and Anca D. Dragan from Cornell Tech and Berkeley Universities. Looking at how Twitter's algorithm selects emotional content, its effects on preferences, and a surprising finding on the "echo chamber" phenomenon. We further break down the study's methodology, its limitations, and why its revelations matter to every Twitter user and those who value public discourse. Whether you're a Twitter user curious about the unseen forces shaping your feed, or a social science enthusiast looking to understand the psychological and sociopolitical implications of algorithmic curation, this episode is sure to provide some food for thought.

In this enlightening episode of Social Science Weekly, we delve into the groundbreaking paper "The spread of true and false news online" by Soroush Vosoughi, Deb Roy, and Sinan Aral, originally published in Science in 2018. We explore a phenomenon that greatly influences our perception of the world - the rapid and indiscriminate spread of true and false information on social media platforms. This comprehensive study sifts through an expansive dataset of tweets from 2006 to 2017, dissecting the mechanics of information diffusion on Twitter and providing a unique perspective on the disparities in the spread of true and false news. We also scrutinize the study's findings: that false news travels faster and reaches more people, and that users spreading false news often have fewer followers and are less active. The element of novelty and the elicitation of emotional responses, particularly surprise and disgust, were also found to significantly contribute to the spread of false news. However, we also acknowledge the limitations of this study, including the confinement of the research to Twitter and the potential for bias introduced by the fact-checking organizations. Join us as we uncover these and other nuances in this intriguing exploration of the digital information age.
