Polarisation and Spread of Misinformation on Social Media
Prof. Dr. Faisal Shafait, National University of Sciences and Technology
Date: 3rd January, 2023
Time: 11:00 am to 12:00 pm
Venue: SINES (next to NSTP), NUST H-12 Campus
Contrary to expectations that the increased connectivity offered by the internet, particularly Online Social Networks (OSNs), would result in a broad consensus on contentious issues, we instead frequently observe the formation of polarised echo chambers, in which only one side of
an argument is entertained. These can progress to filter bubbles, actively filtering contrasting opinions, resulting in vulnerability to misinformation and increased polarisation on social and political issues. These have real-world effects when they spread offline, such as vaccine hesitation and violence. Our work seeks to better understand how echo chambers manifest in different discussions dealing with various issues over an extended period.
