Facebook and the Algorithmic Curation of Content

Facebook has recently got into trouble over an accusation that they are suppressing conservative news stories in the trending news categories. Facebook have an algorithmic system that promotes trending topics to a human curation team, who make the final decision about what gets promoted. Obviously human beings have bias. One of the interesting things that has happened in finance is that banks are using algos more and more to ensure that humans aren't involved in situations where there can be a conflict of interest. One example is the 4pm FX fix which are now required to be handled algorithmically. There's a trend here - algorithms are being used to ensure fairness. Will media companies be forced to have algorithmic editors to remove bias from reporting?
