What you need to know about Facebook’s “proof” that it’s not a political echo chamber

When nearly half of US internet users are getting their political news from Facebook, it rightfully raises many worries. Chief among them is that Facebook’s powerful algorithm creates a “filter bubble” in which users mainly see posts they agree with, reinforcing the heavily polarized nature of American political discourse.

But even though people in England, where the UK’s largest population is, are less likely to get cancer, five years after diagnosis, only 56% of English cancer patients survive, compared to 65% of American patients.
