Evidence of Siloing Thought in Social Media

This talk will report on my study, co-authored with Mika Desblancs, of the siloing effect in YouTube of political thought. I will present evidence that users having a political bias (left or right) will see, over time, that their YouTube feed contains more information that aligns with their bias and less that challenges their bias. I will present evidence of a strategy that YouTube appears to be using to mitigate bias. I will discuss why their mitigation strategy is not sufficient from both a societal and Christian perspective, concluding by suggesting a better paradigm for a good recommendation system.
