Gmail favored left-wring candidates while Outlook favored right-wing candidates. The most popular email provider Gmail favors liberal candidates by marking fewer of their emails as spam, while more emails from conservative candidates are marked as spam, according to a new study. The Department of Computer Science at North Carolina State University conducted a study to find out if spam filtering algorithms (SFAs) have a political bias. The study, titled “A Peek into the Political Biases in Email Spam Filtering Algorithms During US Election 2020,” was conducted between July 1 2020, and November 30, 2020. The researchers created 102 email accounts on Yahoo, Gmail, and Outlook and subscribed to the campaign emails of 156 House, 78 Senate, and two presidential candidates. https://reclaimthenet.org/study-suggests-email-provider-bias-in-sending-candidates-emails-to-spam
