It is definitely true that <a href=\"http:\/\/graphics.wsj.com\/blue-feed-red-feed\/#\/trump\" target=\"_blank\" rel=\"noopener\">there is a lot of easily accessible, clearly identifiable, highly partisan content on social media<\/a>. It is also true that, to some extent, social media users can make choices as to which sources they follow and engage with. Whether people use these choice affordances solely to flock to content reinforcing their political preferences and prejudices, filtering out or avoiding content that espouses other viewpoints, is, however, <strong>an empirical question<\/strong>\u2014not a destiny inscribed in the way social media and their <a href=\"http:\/\/science.sciencemag.org\/content\/348\/6239\/1130\" target=\"_blank\" rel=\"noopener\">algorithms<\/a> function.<\/p>\n<p>To contribute to this conversation, here I present some data from <strong>online<\/strong> <strong>surveys conducted in 2017 in France, Germany, and the United Kingdom <\/strong>immediately after each country\u2019s general elections. (A few days ago I published <a href=\"http:\/\/www.repubblica.it\/politica\/2018\/02\/08\/news\/le_elezioni_i_social_e_le_bolle_ideologiche_ecco_il_profilo_degli_utenti_piu_a_rischio-188165084\/\" target=\"_blank\" rel=\"noopener\">an article in the Italian newspaper <\/a><a href=\"http:\/\/www.repubblica.it\/politica\/2018\/02\/08\/news\/le_elezioni_i_social_e_le_bolle_ideologiche_ecco_il_profilo_degli_utenti_piu_a_rischio-188165084\/\" target=\"_blank\" rel=\"noopener\"><em>la Repubblica<\/em><\/a> where I presented data on Italy telling a similar story.) The surveys were fielded as part of a <a href=\"http:\/\/www.webpoleu.net\/\" target=\"_blank\" rel=\"noopener\">comparative project on social media and political participation<\/a>, funded by the Italian government, for which I serve as Principal Investigator. We commissioned Ipsos to interview samples of 1,750 respondents per country. We constructed these samples to be representative of internet users in each country based on gender, age, education, region of residence, and occupational condition. The research design is the same as the one employed in other research we have published, which you can check out <a href=\"http:\/\/journals.sagepub.com\/doi\/abs\/10.1177\/1461444815616223\" target=\"_blank\" rel=\"noopener\">here<\/a>, <a href=\"http:\/\/journals.sagepub.com\/doi\/abs\/10.1177\/1940161216642152\" target=\"_blank\" rel=\"noopener\">here<\/a>, <a href=\"http:\/\/www.tandfonline.com\/doi\/abs\/10.1080\/10584609.2016.1201558\" target=\"_blank\" rel=\"noopener\">here<\/a>, and <a href=\"http:\/\/www.tandfonline.com\/doi\/abs\/10.1080\/1369118X.2017.1350730\" target=\"_blank\" rel=\"noopener\">here<\/a>. Augusto Valeriani and I are writing <a href=\"https:\/\/cristianvaccari.com\/books\/\">a whole book<\/a> about this and other topics, which will include data from nine Western democracies including the three this post is about. Surveys are imperfect instruments, but (as we argue in the publications linked above) they are still among the best tools to measure users\u2019 experiences across different environments, media, and digital platforms. This is relevant to the question that sparked this post: <strong>to understand whether social media function as filter bubbles, we need to know how prevalent filter bubbles are both on social media and in other environments<\/strong>. Surveys allow to gauge differences and similarities between these spaces.<\/p>\n<p>To find out whether users encounter political content and views they mainly agree and\/or disagree with, we asked respondents <strong>two simple questions<\/strong>: \u201cHow often do you <strong>agree<\/strong> with the political opinions and messages published on social media platforms by the people you follow?\u201d and \u201c\u201dHow often do you <strong>disagree<\/strong> with the political opinions and messages published on social media platforms by the people you follow?\u201d. To compare users\u2019 experiences across different environments, we asked a similar pair of questions focusing on <strong>face-to-face conversations<\/strong> (the phrase we used was \u201cthe opinions of others you speak with about politics, excluding online contacts\u201d) and <strong>mass media<\/strong> (where we asked respondents to focus on \u201cthe political opinions or political contents you see in the news on television or newspapers\u201d). To each question, respondents could answer \u201cAlways or very often\u201d, \u201cOften\u201d, \u201cSometimes\u201d, \u201cNever\u201d, and \u201cI don\u2019t know\u201d. The chart below shows the percentages who answered either \u201cAlways or very often\u201d or \u201cOften\u201d, excluding \u201cDon\u2019t know\u201d answers. The questions on social media were asked only to those respondents who claimed to use at least one social media platform (90% of our sample).<\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-214\" src=\"https:\/\/vaccari.files.wordpress.com\/2018\/01\/picture19.png?w=525\" alt=\"Picture1\" \/><\/p>\n<p>In all three countries, <strong>the percentages of users who claim to often agree with the political content they see on social media are substantially lower than the percentages of users who claim to often disagree with those contents<\/strong>. There are country variations, with more balanced results in Germany (29.3% disagreement, 24.8% agreement) and more lopsided patterns in the UK (32.3% disagreement, 21.6% agreement) and, especially, France (32.9% disagreement, 17.9% agreement). Still, the overall finding is clear: <strong>social media users are more likely to disagree than agree with the political contents they see on these platforms<\/strong>.<\/p>\n<p>Moreover, <strong>citizens are much more likely to encounter disagreeable views on social media than in face-to-face conversations<\/strong>, as we can see by comparing the left and center pane of the figure above. The patterns that emerge for offline discussions are the mirror image of those observed for social media, with substantially more users claiming they often agree with other people they talk to compared with those who claim they often disagree with them. The difference between agreement and disagreement in face-to-face conversations is of about 10% in France and the UK, and a whopping 36.8% in Germany (58.1% agreement, 21.3% disagreement). Thus, <strong>social media augment political pluralism when compared with face-to-face political talk<\/strong>.<\/p>\n<p>However, <strong>television and newspapers are the most important vehicles for political pluralism<\/strong>, as you can see by comparing the left and right panes in the figure. In both the UK and France, twice as many respondents claim they often disagree with the political views expressed in TV and newspapers than those who claim they often agree. In Germany, the difference is still quite large (36% disagree, 26.5% agree) and larger than for social media. Consistent with <a href=\"https:\/\/www.cambridge.org\/core\/journals\/american-political-science-review\/article\/facilitating-communication-across-lines-of-political-difference-the-role-of-mass-media\/59FA5A11AF6875C9BDADA19C6CEBBE9F\" target=\"_blank\" rel=\"noopener\">research by Diana Mutz and Paul Martin<\/a> from nearly two decades ago, in general, <strong>the mass media are the main source of exposure to counter-attitudinal political information<\/strong>.<\/p>\n<p>Assessing the frequency of political agreement and disagreement on social media in isolation from one another is helpful, but how much overlap there is between them? Do people who report often agreeing with others also feel they often disagree with others, or are these separate groups of people, some of whom are in echo chambers while others are constantly battling against others they disagree with? To find out, I combined the answers to the questions on agreement and disagreement. The math is pretty simple, as you can see from the illustration below. Respondents who answered \u201cNever\u201d to both questions were classified as engaging with \u201c<strong>No content<\/strong>\u201c.Respondents who agree more often than they disagree with the content they see are classified as seeing \u201c<strong>Supportive<\/strong>\u201d messages, and those who disagree more often than they agree are confronted with \u201c<strong>Oppositional<\/strong>\u201d messages. Finally, respondents who gave the same answers to both questions were classified as seeing \u201c<strong>Two-sided<\/strong>\u201d content. (Of course, there can always be more than two sides to any political conflict, especially in European party systems; I use this term to echo <a href=\"https:\/\/books.google.co.uk\/books?id=83yNzu6toisC&amp;printsec=frontcover&amp;dq=zaller+nature&amp;hl=en&amp;sa=X&amp;ved=0ahUKEwihhKmJ3ILZAhXqLMAKHXALC_gQ6AEIKTAA#v=onepage&amp;q&amp;f=false\" target=\"_blank\" rel=\"noopener\">John Zaller\u2019s classification of campaign messages<\/a>, which I find helpful to think about these issues.)<\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-219\" src=\"https:\/\/vaccari.files.wordpress.com\/2018\/02\/screen-shot-2018-02-01-at-11-06-29.png?w=525\" alt=\"Screen Shot 2018-02-01 at 11.06.29.png\" \/><\/p>\n<p><strong>Most users claim to agree as often as they disagree with the political content they see on social media<\/strong>, so I classify them as encountering two-sided messages. Among respondents who identify a one-sided tendency in the content they see, <strong>users who predominantly see oppositional content greatly outnumber those who predominantly see supportive content<\/strong>. There are, again, some country variations, with French respondents more likely to see oppositional content (29.5%) than British (26.1%) and German ones (25.8%), and, conversely, German respondents more likely to see supportive content (20%) than British (16.1%) and French ones (12.8%).<\/p>\n<p>Overall, the picture is clear: if you ask social media users to evaluate their levels of agreement and disagreement with the political content they see, <strong>ideological echo chambers and filter bubbles on social media are the exception, not the norm. <\/strong>Being the exception does not mean being non-existent, of course. Based on these estimates, <strong>between one in five and one in eight social media users report being in ideological echo chambers<\/strong>. However, most social media users experience a rather balanced combination of views they agree and disagree with. If anything, <strong>the clash of disagreeing opinions is more common on social media than ideological echo chambers<\/strong>.<\/p>\n<p><a href=\"http:\/\/www.lboro.ac.uk\/departments\/socialsciences\/staff\/cristian-vaccari\/\">Cristian Vaccari<\/a>, Reader in Political Communication, Loughborough University.<\/p>\n<p>This article was originally published on <a href=\"https:\/\/cristianvaccari.com\/\">cristianvaccari.com<\/a>.
