The COVID‐19 pandemic impeded social interaction, negatively affecting well‐being worldwide. To slow virus spread, practices were enacted to minimize face‐to‐face contact, leading to increased social disconnection. As people turned increasingly to online environments (e.g., social media) to fulfill needs for inclusion and belonging, misinformation regarding COVID‐19 simultaneously ran rampant. The purpose of the current study was to examine whether impeded social inclusion may have contributed to the spread of misinformation. We recruited a sample of adult social media users in the United States ( N = 431) and randomly assigned them to be either included, ostracized (i.e., ignored), or rejected (i.e., to receive explicitly negative attention). Participants subsequently rated their willingness to share COVID‐19 claims via social media (in fact, all claims were false). Participants learned that sharing some claims would likely lead to high expected engagement from others on social media (e.g., “likes”), whereas some claims would likely lead to little expected engagement. While information sharing was low in our sample, participants were more willing to share claims that they believed would lead to higher levels of engagement—consistent with the idea that sharing information is motivated not only by the desire to educate others but also to elicit social connection. However, this behavioral intention was no more common among participants who had been momentarily ostracized or rejected online than among participants who had been included. Future research should continue to explore the link between social exclusion and the motivation to disseminate (mis)information beyond a pandemic‐related context.
