"We believe strongly in being impartial, and we strive to enforce our rules impartially," he continued. "We do not shadowban anyone based on political ideology. In fact, from a simple business perspective and to serve the public conversation, Twitter is incentivized to keep all voices on the platform." The company has been accused of discriminating against and shadow banning conservatives by President Trump and others. But it has continued to deny those accusations. Dorsey's statement also says that silencing any political perspective "is antithetical to our commitment to free expression."
In his discussion of Twitter's algorithms, Dorsey also addresses recent high-profile incidents including a search issue that caused both Democrat and Republican accounts to not be auto-suggested when users were searching for them. Dorsey says that the issue was fixed within 24 hours once identified and upon further investigation, Twitter found that the problem didn't have an effect on Congressional leaders' follower counts. Dorsey also noted that a recent feature that filtered out accounts that might be abusive from users' searches was ultimately turned off because the company decided a "higher level of precision" was needed for it to be effective.
To further address accusations of political bias, Twitter recently analyzed tweets sent by members of Congress for 30 days and Dorsey said that the company found no significant difference between the number of times a tweet sent by a Democrat was viewed versus a tweet published by a Republican.
Other issues mentioned by Dorsey include previous and current efforts to fight malicious activity from foreign groups, various functions of its algorithms and its attempts to improve conversations on its platform. Earlier this year, Twitter reached out to experts for ideas on how to boost healthy and civil conversations on its platform and Dorsey discusses that effort in his statement. He said that the company has been collaborating with the nonprofit group Cortico and the MIT Media Lab, exploring how to measure health on the platform, and will also partner with the University of Oxford and Leiden University on the effort.
"The purpose of Twitter is to serve the public conversation, and we do not make value judgments on personal beliefs," Dorsey concluded. "We are focused on making our platform -- and the technology it relies upon -- better and smarter over time and sharing our work and progress with this committee and the American people. We think increased transparency is critical to promoting healthy public conversation on Twitter and earning trust."
