Definitely.
The emergence of echo chambers has given rise to a problem: digital platforms overall make it easier for individuals to adhere to beliefs, even causes. In fact, platforms do more than just allow for a message to be shared; they dictate that the message be shared, using recommendation algorithms—which are purported to know what users like—to edit, select and customize the message.
You may have noticed that, when you shop online for a pair of shoes, when you open your browser a few hours or days later, Google shows you ads with different pairs of shoes. It's exactly the same thing for extremist ideologies. If you start visiting certain sites on Twitter, Facebook and other social media, going forward, you will always see similar beliefs promoted and that will help crystallize those beliefs.
Digital platforms contribute to something else: they fuel rumours that are sometimes, but not always, based on conspiracy theories. Those rumours are especially appealing to people who have certain questions, sometimes legitimate ones—in connection with the COVID‑19 health measures, for instance. After repeated exposure to much more sophisticated conspiracy theories that are explained in simple, but understandable, terms, people can get drawn in by groups and individuals who are promoting extremist ideologies online.
