Contemporary social media platforms offer a rich ground for the spread of misinformation.The exact sharing and motivation behind why misinformation spreads through social media so easily remains unknown. A 2018 study of Twitter determined that, compared to accurate information, false information spread significantly faster, further, deeper, and more broadly. Combating its spread is difficult for two reasons: the profusion of information sources, and the generation of "echo chambers". The profusion of information sources makes the reader's task of weighing the reliability of information more challenging, heightened by the untrustworthy social signals that go with such information. The inclination of people to follow or support like-minded individuals leads to the formation of echo chambers and filter bubbles. With no differing information to counter the untruths or the general agreement within isolated social clusters, some writers argue the outcome is a dearth, and worse, the absence of a collective reality, some writers argue. Although social media sites have changed their algorithms to prevent the spread of fake news, the problem still exists. Furthermore, research has shown that while people may know what the scientific community has proved as a fact, they may still refuse to accept it as such.
