“…To test the extent to which online interactions are impacted by geographical distance, we adopted a metric from related work 72 .

Past research has attributed the circulation of online news to two main factors—individual characteristics (e.g., a person’s information literacy) and social media effects (e.g., algorithm-mediated information diffusion)—and has overlooked a third one: the critical mass created by the offline self-segregation of Americans into like-minded geographical regions such as states (a phenomenon called ‘The Big Sort’). We hypothesized that this latter factor matters for the online spreading of news not least because online interactions, despite having the potential of being global, end up being localized: interaction probability is known to rapidly decay with distance. Upon analysis of more than 8M Reddit comments containing news links spanning four years, from January 2016 to December 2019, we found that Reddit did not work as an ‘hype machine’ for news (as opposed to what previous work reported for other platforms, circulation was not mainly caused by platform-facilitated network effects). Rather, news circulation in Reddit worked as a supply-and-demand system: news items scaled linearly with the number of users in each state (with a scaling exponent $$\beta$$ β $$\approx 1$$ ≈ 1 , and a goodness of fit $$R^2\approx 0.95$$ R 2 ≈ 0.95 ). Furthermore, deviations from such a universal pattern were best explained by state-level personality and cultural factors ($$R^2\approx \{0.12, 0.39\}$$ R 2 ≈ { 0.12 , 0.39 } ), rather than socioeconomic conditions ($$R^2\approx \{0.15, 0.29\}$$ R 2 ≈ { 0.15 , 0.29 } ) or political characteristics ($$R^2\approx \{0.06, 0.21\}$$ R 2 ≈ { 0.06 , 0.21 } ). Higher-than-expected circulation of any type of news was found in states characterised by residents who tend to be less diligent in terms of their personality (low in conscientiousness) and by loose cultures understating the importance of adherence to norms (low in cultural tightness). Interestingly, the combination of those factors with low levels of education was then associated with the circulation of a particular type of news, that is, misinformation. These results suggest that online interactions are geographically bounded and, as such, news circulation cannot be studied purely as an Internet phenomenon but should be grounded into a user’s offline cultural environment, which has become increasingly segregated over the decades, and is admittedly hard to change.

Past research has attributed the online circulation of misinformation to two main factors -individual characteristics (e.g., a person's information literacy) and social media effects (e.g., algorithm-mediated information diffusion) -and has overlooked a third one: the critical mass created by the offline self-segregation of Americans into like-minded geographical regions such as states (a phenomenon called 'The Big Sort'). We hypothesized that this latter factor matters for the online spreading of misinformation not least because online interactions, despite having the potential of being global, end up being localized: interaction probability is known to rapidly decay with distance.
