Here is some pretty objective and compelling analysis of Twitter’s bias against conservatives.
Many conservatives believe that social media companies are biased against their views. This includes Donald Trump, who last year accused Twitter of “shadow banning” Republicans, and promised to “look into this discriminatory and illegal practice.” A few months later, Twitter CEO Jack Dorsey made a categorical denial of any bias while testifying before Congress:
Let me be clear about one important and foundational fact: Twitter does not use political ideology to make any decisions, whether related to ranking content on our service or how we enforce our rules. We believe strongly in being impartial, and we strive to enforce our rules impartially.
Not everyone is convinced. A June, 2018 Pew poll found that 72% of Americans believe that social media companies censor views they don’t like, with members of the public being four times more likely to report a belief that such institutions favor liberals over conservatives than the opposite. Podcasters Joe Rogan and Sam Harris both received backlash from their respective audiences for not pressing Dorsey hard enough on the censorship issue.
Until now, conservatives have had to rely on anecdotes to make their case. To see whether there is an empirical basis for such claims, I decided to look into the issue of Twitter bias by putting together a database of prominent, politically active users who are known to have been temporarily or permanently suspended from the platform. My results make it difficult to take claims of political neutrality seriously. Of 22 prominent, politically active individuals who are known to have been suspended since 2005 and who expressed a preference in the 2016 U.S. presidential election, 21 supported Donald Trump.
I began my analysis by compiling a list of every prominent individual or political party known to have been banned from Twitter since its founding. As a proxy for prominence, I used the criterion of whether the ban was important enough to warrant coverage in mainstream news sources. With the help of two research assistants, I searched both conservative and liberal media sources.
