On Monday, the Institute for Strategic Dialogue, a London-based think tank that researches extremism, released some timely data showing that some of the same politicians calling out Twitter’s inaction are indeed facing more of attacks online than other politicians. 

The study: Researchers collected publicly tagged mentions on Twitter and Facebook for a handful of politicians for two weeks in June and July, scrutinizing them manually and using AI to identify abusive posts. 

Overall, researchers found that women and people of color were “far more likely than men to be abused on Twitter.” They found that women received an average of 12% more abuse on Facebook than male politicians. Between 5 and 10% of mentions of most male politicians were considered abusive, while mentions of women politicians on Twitter contained abuse between 15 and 39% of the time. 

Overall, women were targeted much more personally by the tweets in the study. While male politicians primarily faced abuse that used general terms, women—and in particular, Representatives Alexandria Ocasio-Cortez and Nancy Pelosi—were attacked with deeply personal and gendered language. 

The conclusion: The fact that these groups face much more harassment should be surprising to literally nobody who has been on Twitter. But the study is of such a small number of politicians that it is easy to read too much into the specifics. 

However, the report helps to quantify one of the platform’s longest-running issues at a crucial moment, as Kamala Harris, the Democrat’s vice presidential candidate, prepares to debate Vice President Mike Pence, and as activists raise alarms about online voter suppression campaigns targeting women and non-white voters. 

The findings may not really be new, but they reinforce what women and people of color have been saying about Facebook, Twitter, and other major social media companies for years: that while the sites may increasingly have policies banning abusive behavior, the enforcement of those policies often leaves its most common targets open to sustained, coordinated harassment.
