Facebook Deactivation Experiment Reveals Surprising Impacts on Misinformation and Political Engagement
A groundbreaking study involving over 35,000 Facebook and Instagram users just before the 2020 US presidential election has shed light on the effects of social media disconnection during a politically charged period. The experiment, published in the journal PNAS, involved paying a randomly selected group of participants to deactivate their accounts for either one or six weeks. Surprisingly, the study found that disconnecting from these platforms had minimal impact on overall political opinions, polarization, or beliefs about election fraud. However, one key finding emerged: deactivating Facebook, but not Instagram, reduced belief in circulating misinformation.
This decrease in misinformation susceptibility coincided with a decline in online political participation among the Facebook-deactivated group. The study, conducted by over 30 academics from US universities in collaboration with Meta researchers, is part of a larger project that previously revealed findings such as conservatives’ higher consumption of misinformation on Facebook. The sheer scale of the experiment, involving ten times the sample size of previous studies, makes it the most comprehensive analysis of social media deactivation to date.
Stanford University professor Matthew Gentzkow, one of the study’s authors, highlights two primary takeaways: the lack of significant impact on core political views despite disconnection, and the notable reduction in misinformation belief alongside a decrease in political knowledge among Facebook-deactivated users. This suggests that Facebook serves as a conduit for both accurate and false information, raising complex questions about the platform’s role in shaping public discourse. The observed impact on misinformation belief was unexpectedly large, given the generally low levels of exposure reported in prior research, according to Gentzkow.
Despite the study’s groundbreaking scope, utilizing unprecedented access to internal Meta data, limitations exist in extrapolating these findings to the broader societal impact of Facebook. The study only captures the behavior of individuals within a society where the majority continue to use the platform. It cannot definitively answer the hypothetical question of what the political landscape would look like in a world without Facebook, a scenario acknowledged by both Gentzkow and independent expert David García, a professor at the University of Konstanz.
The research also clarified the distinct roles of Facebook and Instagram in the political arena. While both platforms experienced a decrease in online political participation among deactivated users, only Facebook deactivation demonstrably impacted misinformation belief and political knowledge. This suggests that despite Instagram’s growing popularity, Facebook remains the dominant force in shaping political outcomes online. Interestingly, those who deactivated from Facebook for six weeks exhibited greater skepticism towards political information encountered upon their return, a shift observed on both Facebook and Instagram. This suggests that time away from the platforms heightened user awareness of the prevalence of low-quality or inaccurate content.
The study explored several other crucial aspects of political engagement. While online political participation declined among Facebook-deactivated participants, voter turnout remained unchanged, indicating that online activity does not necessarily translate directly to offline voting behavior. Furthermore, deactivating either platform did not significantly affect political polarization, perceived election legitimacy, or candidate preference. An intriguing, though statistically inconclusive, finding suggested that Facebook deactivation might have marginally decreased support for Donald Trump and influenced voter turnout among Republicans and Democrats. However, researcher David García points out that the study’s high standard of evidence may have underestimated the potential significance of this result, given the typically close margins of US elections. The intricacies of these findings demand careful interpretation.
The study itself involved a complex recruitment process. Meta invited millions of users to participate, with a significantly smaller subset completing the experiment, which included surveys and a financial incentive for six-week deactivation. This meticulous methodology, coupled with the unprecedented access to internal data, provides valuable insights into the complex relationship between social media usage and political behavior, though further research remains essential to fully understand the societal implications of these platforms.
