One of the dangerous conveniences afforded by social media is that news consumption has changed from pull to push. With personalized feeds, readers no longer need to visit individual news sources. Instead, users rely on personalization algorithms to decide what they should read. Because social media companies make money from engagement, these algorithms are tuned to show us what we want to see.
The implication of this is that social media companies have stopped showing users content that they are unlikely to agree with in favor of posts that we are likely to agree with - the perfect breeding ground for fake news. Since what we want to read isn't necessarily what we should be reading, those who wish to be well-informed should opt out of personalization algorithms when determining what to read and actively seek out a healthy news diet.
