Russian Twitter Campaigns During the 2016 Presidential Race Didn’t Change Voting Behavior

Exposure to Russian Twitter campaigns in 2016 presidential race was highly concentrated, largely limited to strongly partisan Republicans.

New study shows online push by foreign disinformation accounts didn’t change attitudes or voting behavior—but disinformation effort may still have had consequences.

Russian Twitter campaigns during the 2016 presidential race primarily reached a small subset of users, most of whom were highly partisan Republicans, shows a new study by NYU’s Center for Social Media and Politics. In addition, the international research team found that despite Russia’s influence operations on the platform, there were no measurable changes in attitudes, polarization, or voting behavior among those exposed to this foreign influence campaign.

Previous research and government investigations have concluded that Russian interference in the 2016 U.S. election was designed to influence the voting behavior of Americans in favor of GOP nominee Donald Trump, either by shifting support toward Trump himself or by encouraging disaffected liberals—often Bernie Sanders voters—to vote for a third-party candidate or to abstain from voting altogether.

“Despite this massive effort to influence the presidential race on social media and a widespread belief that this interference had an impact on the 2016 U.S. elections, potential exposure to tweets from Russian trolls that cycle was, in fact, heavily concentrated among a small portion of the American electorate—and this portion was more likely to be highly partisan Republicans,” explains Professor Joshua A. Tucker, co-director of the Center for Social Media and Politics (CSMaP) and one of the authors of the paper, which appears in the journal Nature Communications.

Potential exposure to Russian coordinated influence accounts, by the Internet Research Agency, an organization closely linked to the Russian government, was heavily concentrated: only 1% of users in the study accounted for 70% of exposures. In addition, those who identified as “Strong Republicans” were exposed to roughly nine times as many posts from Russian foreign influence accounts than were those who identified as Democrats or Independents.

Limited Impact on Attitudes, Polarization, and Voting Behavior

The study, which included researchers from the University of Copenhagen, Trinity College Dublin, and Technical University of Munich and examined social media users’ behaviors and attitudes in both April and October of 2016, also concluded that there was no relationship between exposure to the Russian foreign influence campaign and changes in attitudes, polarization, or voting behavior.

Despite these results, the researchers caution that Russia attempts to alter the outcome of the election may have had other effects.

Broader Implications for Electoral Integrity and Public Trust

“It would be a mistake to conclude that simply because the Russian foreign influence campaign on Twitter was not meaningfully related to individual-level attitudes that other aspects of the campaign did not have any impact on the election, or on faith in American electoral integrity,” says the University of Copenhagen’s Gregory Eady, one of the study’s co-lead authors.

“Debate about the 2016 U.S. election continues to raise questions about the legitimacy of the Trump presidency and to engender mistrust in the electoral system, which in turn may be related to Americans’ willingness to accept claims of voter fraud in the 2020 election and future elections,” adds Trinity College Dublin’s Tom Paskhalis, the other co-lead author of the study.

Domestic Content Overwhelms Russian Influence on Twitter

Notably, the study also found that exposure to the Russian influence campaign on Twitter was significantly eclipsed by content from domestic news media and politicians. On average, the study’s respondents were exposed to roughly four posts from Russian foreign influence accounts per day in October of 2016. But, over the same period, they were exposed to an average of 106 posts on average per day from national news media and 35 posts per day from U.S. politicians.

“In other words, online users saw 25 times more posts from national news media and nine times as many posts from politicians than those from Russian foreign influence accounts,” observes Technical University of Munich’s Jan Zilinsky, one of the study’s authors, “to say nothing of what they might have learned about the election from other media, such as television or online news.”

The paper’s other authors were Jonathan Nagler, a professor in NYU’s Department of Politics, and Richard Bonneau, a professor in NYU’s Department of Biology and Courant Institute of Mathematical Sciences. Tucker, also director of NYU’s Jordan Center for the Advanced Study of Russia, and Nagler are co-directors of CSMaP.

The study analyzed a three-wave longitudinal survey of nearly 1,500 U.S. respondents conducted by YouGov. The respondents, who consented both to provide their Twitter account information for research purposes and to answer questions concerning their political attitudes and beliefs at multiple points during the 2016 U.S. election campaign, were surveyed in April 2016 and October 2016 as well as shortly after the election—to indicate whether they voted and, if so, for whom. The composition of the respondents was approximately representative of the demographic profile of the U.S. voting-age public.
