Social media has become one of the most powerful and ubiquitous means by which individuals curate, share, and communicate information with their friends, family, and the world at large. Indeed, 90% of the American adolescents are active social media users, as well as 65% of American adults (Perrin, 2015; see also Duggan & Brenner, 2013). Despite this, psychologists are only beginning to understand the mnemonic consequences associated with social media use. In this article, we will distill this nascent literature by focusing on two primary factors: the type of information (personal vs. public) and the role (producer vs. consumer) individuals play when engaging with social media. In particular, we will highlight research examining induced forgetting for personal information as well as false memories and truthiness for public information. We will end by providing some tentative conclusions and a discussion of areas in need of additional research that will provide a more holistic understanding of the mnemonic consequences associated with social media use.
