A Peek into the Political Biases in Email Spam Filtering Algorithms During US Election 2020

Hassan Iqbal, Usman Mahmood Khan, Hassan Ali Khan, Muhammad Shahzad

Abstract

Email services use spam filtering algorithms (SFAs) to filter emails that are unwanted by the user. However, at times, the emails perceived by an SFA as unwanted may be important to the user. Such incorrect decisions can have significant implications if SFAs treat emails of user interest as spam on a large scale. This is particularly important during national elections. To study whether the SFAs of popular email services have any biases in treating the campaign emails, we conducted a large-scale study of the campaign emails of the US elections 2020 by subscribing to a large number of Presidential, Senate, and House candidates using over a hundred email accounts on Gmail, Outlook, and Yahoo. We analyzed the biases in the SFAs towards the left and the right candidates and further studied the impact of the interactions (such as reading or marking emails as spam) of email recipients on these biases. We observed that the SFAs of different email services indeed exhibit biases towards different political affiliations. We present this and several other important observations in this paper.

    • I believe this is the study mentioned in the tweet: https://arxiv.org/pdf/2203.16743.pdf I'd say that mass unsolicited emails asking for money are the definition of spam and by default mail filters should get rid of all - republican, democrat, or Nigerian princess. Google rolled…

    • “Our observations in §4.1 to answer Q1 revealed that all SFAs exhibited political biases in the months leading upto the 2020 US elections. Gmail leaned towards the left (Democrats) whereas Outlook and Yahoo leaned towards the right (Republicans). Gmail marked 59.3% more emails…

    • I kinda agree with Sen. Grassley, although he doesn't seem to be articulating the issue very well. Remember what happened in 2020: near the presidential election, you couldn't even DM the URL of the NY Post story to others. [1] That's blatant censorship, no matter the merits of…

    • There is at least the appearance of bias in these algorithms, with Google being a rather extreme example. It’s not easily explained away by other factors. Study showed a smaller bias towards the right for Yahoo/Outlook. I wouldn’t be too surprised if a number of Dems support…
