Query: YouTube, The Great Radicalizer? Auditing and Mitigating Ideological
  Biases in YouTube Recommendations   Recommendations algorithms of social media platforms are often criticized for
placing users in "rabbit holes" of (increasingly) ideologically biased content.
Despite these concerns, prior evidence on this algorithmic radicalization is
inconsistent. Furthermore, prior work lacks systematic interventions that
reduce the potential ideological bias in recommendation algorithms. We conduct
a systematic audit of YouTube's recommendation system using a hundred thousand
sock puppets to determine the presence of ideological bias (i.e., are
recommendations aligned with users' ideology), its magnitude (i.e., are users
recommended an increasing number of videos aligned with their ideology), and
radicalization (i.e., are the recommendations progressively more extreme).
Furthermore, we design and evaluate a bottom-up intervention to minimize
ideological bias in recommendations without relying on cooperation from
YouTube. We find that YouTube's recommendations do direct users -- especially
right-leaning users -- to ideologically biased and increasingly radical content
on both homepages and in up-next recommendations. Our intervention effectively
mitigates the observed bias, leading to more recommendations to ideologically
neutral, diverse, and dissimilar content, yet debiasing is especially
challenging for right-leaning users. Our systematic assessment shows that while
YouTube recommendations lead to ideological bias, such bias can be mitigated
through our intervention.
