Polarized users reinforce their preexisting beliefs through the influence of their like-minded neighbors. In the left panel, for any user $u\in V_{\mathrm{science}}^L$, we show the peer influence probability ${\mathrm{PIP}}_{\mathrm{science}}^u$ of $N_s(u)$ on u across the pages of ${𝒫}_{science}^u$, versus the number of likes ${\log }_2(\theta (u))$. Segments represent the average of peer influence probabilities regarding users with a liking activity in the range of the corresponding bin. The right panel shows the same quantities for polarized users in $V_{\mathrm{conspir}}^L$.
