"The proliferation of political mis/disinformation on social media has led many scholars to embrace “inoculation” techniques, where individuals are trained to identify the signs of low-veracity information prior to exposure. Coordinated information operations frequently spread mis/disinformation ... through inauthentic or “troll” accounts that appear to be trustworthy members to the targeted polity, as in Russia's attempts to influence the 2016 US presidential election. We experimentally tested the efficacy of inoculation against inauthentic online actors, using the Spot the Troll Quiz, a free, online educational tool that teaches how to spot markers of inauthenticity. Inoculation works in this setting. Across an online US nationally representative sample (N = 2,847), which also oversampled older adults, we find that taking the Spot the Troll Quiz (vs. playing a simple game) significantly increases participants’ accuracy in identifying trolls among a set of Twitter accounts that are novel to participants. This inoculation also reduces participants’ self-efficacy in identifying inauthentic accounts and reduced the perceived reliability of fake news headlines, although it had no effect on affective polarization. And while accuracy in the novel troll-spotting task is negatively associated with age and Republican party identification, the Quiz is equally effective on older adults and Republicans as it was on younger adults and Democrats."

"Through this research we gained insight into tactics employed by state-backed social media disinformation. With that goal, we explored user interactions with inauthentic Twitter accounts. We used multiple procedures to measure the ways in which users talked with and about the accounts employed by t ... he Russian-affiliated Internet Research Agency in the month before the 2016 U.S. Election. We found that users were overwhelming supportive of the IRA accounts, a fact that calls into question the standard representation of these accounts as “trolls.” Users were particularly supportive of the accounts that pretended to be part of a particular ideological group (on both the left and right), supporting arguments that a strategy of building connections with like-minded people was central to the IRA campaign. This strategy seems to work—on days that the Russian accounts received more support they also received more engagement." (Lay summary) more
