# The Ebb and Flow of Controversial Debates on Social Media

## TL;DR

This study examines how polarization on controversial topics on Twitter changes over time and in response to external events, revealing that activity correlates with polarization but no consistent long-term trend exists.

## Contribution

It provides a longitudinal analysis of polarization dynamics on Twitter, highlighting the relationship between activity spikes and polarization without identifying a persistent long-term trend.

## Key findings

- Increased activity correlates with increased polarization.
- No consistent long-term trend in polarization over 2011-2016.
- External events trigger activity surges and polarization shifts.

## Abstract

We explore how the polarization around controversial topics evolves on Twitter - over a long period of time (2011 to 2016), and also as a response to major external events that lead to increased related activity. We find that increased activity is typically associated with increased polarization; however, we find no consistent long-term trend in polarization over time among the topics we study.
