Are there political biases on Wikipedia?

Jim O'Shaughnessy's guest, Gurwinder Bhogal, discussed the potential for political bias on Wikipedia on the Infinite Loops 2023. Bhogal expressed distrust in Wikipedia, noting that although it appears that anybody can edit it, there is actually a form of gatekeeping in place. He pointed out that only certain sources are permitted for citations, and these sources often have a consistent political leaning. This gatekeeping can lead to biased content or speculative claims being presented as facts on the platform 1.
