I think the replicability affordance of social media, its potential to like, retweet, and reshare information, is an important stimulate of the so-called illusory truth effect. If we hear the same false information repeatedly, we more easily come to believe it. Social media and its replicability affordance certainly played a huge role in the illusory truth effect. I think that this phenomenon, in fact, confirms our media affect theories. Messages have the highest impact when they converge with the opinions and norms in the environment of the message recipient. In my DSM Model, the Differential Susceptibility to Media Effects Model, which I co-developed with Jochen Peter, we have called this effect the context-content convergence effect. The DSM Model is my most cited model. I wrote it together with Jochen Peter, and in this model we integrated insight from a dozen earlier media affect theories. An important premise of most of these theories is that media effects are conditional, which means that they do not equally hold for all media users. Based on these earlier theories, I tried to conceptualize three types of differential susceptibility to media effects: dispositional, developmental, and social susceptibility. I already gave one example of social susceptibility by means of the context-content convergent hypothesis. This hypothesis explains why media messages that converge with yourthe opinions, values and norms in one's environment have a particularly high impact on media users. Our DSM model explains, for example, how one's pre-existing moods can predict social media use. Low moods can lead some social media users to browse positive information, which make them happy afterwards. But among some others, it can lead to doom scrolling, the repeated exposure to negative messages, which could worsen their already low mood. I think the challenge for communication scholars is to figure out the specific characteristics and circumstances of both these doom scrollers. I hope that we, in our team, will soon be better able to answer these questions.
