We estimated ideological preferences of 3.8 million Twitter users and, using a data set nearly 150 tweets concerning 12 political and nonpolitical issues, explored whether online communication resembles an “echo chamber” (as result selective exposure segregation) or “national conversation.” observed that information was exchanged primarily among individuals with similar in the case issues (e.g., 2012 presidential election, 2013 government shutdown) but not many other current events Boston...
Significance Twitter and other social media platforms are believed to have altered the course of numerous historical events, from Arab Spring US presidential election. Online networks become a ubiquitous medium for discussing moral political ideas. Nevertheless, field psychology has yet investigate why some ideas spread more widely than others.

A poisonous cocktail of othering, aversion, and moralization poses a threat to democracy
In countries where citizens have strong grievances against the regime, attempts to address these in course of daily life are likely entail high costs coupled with very low chances success any meaningful sense; consequently, most will choose not challenge thus reflecting now well-known collective action problem. When a regime commits electoral fraud, however, an individual's calculus regarding whether participate protest can be changed significantly. This argument yields important...
This article provides a detailed set of coding rules for disaggregating electoral volatility into two components: caused by new party entry and old exit, vote switching across existing parties. After providing an overview both types in post-communist countries, the causes are analysed using larger dataset than those used previous studies. The results startling: most findings based on elections countries included studies disappear. Instead, exit is found to be largely function long-term...
Are legislators responsive to the priorities of public? Research demonstrates a strong correspondence between issues about which public cares and addressed by politicians, but conclusive evidence who leads whom in setting political agenda has yet be uncovered. We answer this question with fine-grained temporal analyses Twitter messages during 113th US Congress. After employing an unsupervised method that classifies tweets sent citizens into topics, we use vector autoregression models explore...
It is often claimed that social media platforms such as Facebook and Twitter are profoundly shaping political participation, especially when it comes to protest behavior. Whether or not this the case, analysis of “Big Data” generated by usage offers unprecedented opportunities observe complex, dynamic effects associated with large‐scale collective action movements.

Social media have provided instrumental means of communication in many recent political protests. The efficiency online networks disseminating timely information has been praised by commentators; at the same time, users are often derided as “slacktivists” because shallow commitment involved clicking a forwarding button. Here we consider role these peripheral participants, immense majority who surround small epicenter protests, representing layers diminishing activity around committed...
How can one technology—social media—simultaneously give rise to hopes for liberation in authoritarian regimes, be used repression by these same and harnessed antisystem actors democracy? We present a simple framework reconciling contradictory developments based on two propositions: 1) that social media voice those previously excluded from political discussion traditional media, 2) although democratize access information, the platforms themselves are neither inherently democratic nor...
A major point of debate in the study Internet and politics is extent to which social media platforms encourage citizens inhabit online “bubbles” or “echo chambers,” exposed primarily ideologically congenial political information. To investigate this question, we link a representative survey Americans with data from respondents’ public Twitter accounts ( N = 1,496). We then quantify ideological distributions users’ environments by merging validated estimates user ideology full set followed...
Scholars and commentators have debated whether lower-threshold forms of political engagement on social media should be treated as being conducive to higher-threshold modes participation or a diversion from them. Drawing an original survey representative sample Italians who discussed the 2013 election Twitter, we demonstrate that more respondents acquire information via express themselves politically these platforms, they are likely contact politicians e-mail, campaign for parties candidates...

Based on online surveys of representative samples Italian German individuals posted at least...

We investigated the effects of Facebook’s and Instagram’s feed algorithms during 2020 US election. assigned a sample consenting users to reverse-chronologically-ordered feeds instead default algorithms. Moving out algorithmic substantially decreased time they spent on platforms their activity. The chronological also affected exposure content: amount political untrustworthy content saw increased both platforms, classified as uncivil or containing slur words Facebook, from moderate friends...
