A popular argument that is commonly put forth as an explanation linking digital technologies to political polarization is related to their ability to foster the emergence of echo chambers where extremist ideas are amplified. Sunstein (2018), a leading proponent of this view, argues that the main characteristic of social networking sites is that they allow politically like-minded individuals to find one another. In this environment, citizens are only exposed to information that reinforces their political views and remain isolated from other individuals with opposing views, in part due to the filtering effects of ranking algorithms that generate filter bubbles (Pariser, 2011) and create incentives for publishers to share clickbait and hyperpartisan content (Benkler et al, 2018). The outcome of this process is a society that is increasingly segregated along partisan lines, and where compromise becomes unlikely due to rising mistrust on public officials, media outlets, and ordinary citizens on the other side of the ideological spectrum.
一个流行的观点通常被用来解释数字技术与政治两极分化之间的联系,这与数字技术能够促进回音室的出现有关,回音室是极端主义思想被放大的地方。桑斯坦(2018)是这一观点的主要支持者,他认为社交网站的主要特征是它们允许政治志同道合的个人找到彼此。在这种环境下,公民只会接触到强化其政治观点的信息,并与持反对意见的其他个人保持隔离,部分原因是排名算法的过滤作用产生了过滤气泡(Pariser, 2011),并为出版商分享标题党和超党派内容创造了激励(Benkler等人,2018)。这一过程的结果是,社会的党派界限日益分化,由于对政府官员、媒体和意识形态另一边的普通公民日益不信任,妥协变得不太可能。

Bots and Computational Propaganda: Automation for Communication and Control 机器人和计算宣传:通信和控制的自动化

Public awareness surrounding the threat of political bots, of international fears about armies of automated accounts taking over civic conversations on social media, reached a peak in the spring of 2017. OnMay 8 of that year, former Acting US Attorney General Sally Yates and former US Director of National Intelligence James R. Clapper Jr. sat before Congress to testify on what they called “the Russian toolbox” used in online efforts to manipulate the 2016 US election (Washington Post Staff 2017). In response to their testimony and a larger US intelligence community (IC) report on the subject Senator Sheldon Whitehouse said, “I went through the list [of tools used by the Russians] . . . it looked like propaganda, fake news, trolls, and bots. We can all agree from the IC report that those were in fact used in the 2016 election” (Washington Post Staff 2017). Yates and Clapper argued that the Russian government and its commercial proxy – the Internet Research Agency (IRA) – made substantive use of bots to spread disinformation and inflame polarization during the 2016 US presidential election. These comments mirrored concurrent allegations made by other public officials, but also by academic researchers and investigative journalists, around the globe. Eight months earlier, during a speech before her country’s parliament German Chancellor Angela Merkel raised concerns that bots would affect the outcome of their upcoming election (Copley 2016). Shortly thereafter, the New York Times described the rise of “a battle among political bots” on Twitter. Around the same time, research from the University of Southern California’s Information Sciences Institute concretized the ways that social media bots were being used to manipulate public opinion:
公众对政治机器人威胁的意识,以及国际社会对大量自动账户接管社交媒体上公民对话的担忧,在2017年春天达到了顶峰。当年5月8日,美国前代理司法部长萨利·耶茨和美国前国家情报总监詹姆斯·克拉珀在国会就他们所谓的“俄罗斯工具箱”在网络上操纵2016年美国大选作证。参议员谢尔登·怀特豪斯(Sheldon Whitehouse)在回应他们的证词和一份更大的美国情报界(IC)关于该主题的报告时说:“我仔细研究了(俄罗斯人使用的)工具清单……它看起来像是宣传、假新闻、喷子和机器人。我们都可以从IC的报告中同意,这些实际上是在2016年选举中使用的。”(华盛顿邮报职员2017)耶茨和克拉珀认为,俄罗斯政府及其商业代理——互联网研究机构(IRA)——在2016年美国总统大选期间大量利用机器人传播虚假信息,煽动两极分化。这些言论反映了全球其他政府官员以及学术研究人员和调查记者同时提出的指控。八个月前,德国总理安格拉·默克尔在她的国家议会发表演讲时表示担心机器人会影响即将到来的选举结果(Copley 2016)。此后不久,《纽约时报》在推特上描述了“政治机器人之间的战斗”的兴起。大约在同一时间,南加州大学信息科学研究所(University of Southern California’s Information Sciences Institute)的研究具体化了社交媒体机器人被用来操纵公众舆论的方式:

Comparative Media Regulation in the United States and Europe 美国和欧洲媒体监管的比较
Pub Date : 2020-08-31 DOI: 10.1017/9781108890960.010
F. Fukuyama, Andrew J. Grotto
In current debates over the Internet’s impact on global democracy, the prospect of state regulation of social media has been proffered as a solution to problems like fake news, hate speech, conspiracy-mongering, and similar ills. For example, US Senator Mark Warner has proposed a bill that would enhance privacy protections required of internet platforms, create rules for labeling bot accounts, and change the legal terms of the platforms’ legal relationship with their users. In Europe, regulation has already been enacted in the form of the European Union’s General Data Protection Regulation (GDPR) and new laws like the Network Enforcement Law (NetzDG). This chapter will survey this rapidly developing field, putting current efforts of liberal democracies to regulate internet content in the broader perspective of legacy media regulation. As we will see, there are very different national approaches to this issue among contemporary liberal democracies, and in many respects the new internet regulations, actual and proposed, are extensions of existing practices. We conclude that, in the US case, content regulation will be very difficult to achieve politically and that antitrust should be considered as an alternative. Media regulation is a sensitive and controversial topic in all liberal democracies. The US Constitution’s First Amendment protects freedom of speech, while media freedom is guaranteed in various legal instruments governing the European Union and the Council of Europe, as well as in the European Convention on Human Rights. Freedom of speech is normatively regarded as critical to the proper functioning of a liberal democracy, and the
在当前关于互联网对全球民主影响的辩论中,国家监管社交媒体的前景被视为解决假新闻、仇恨言论、阴谋论和类似弊病等问题的办法。例如,美国参议员马克·华纳(Mark Warner)提出了一项法案,该法案将加强对互联网平台的隐私保护,为标记机器人账户制定规则,并改变平台与其用户法律关系的法律条款。在欧洲,监管已经以欧盟的《通用数据保护条例》(GDPR)和《网络执法法》(NetzDG)等新法律的形式颁布。本章将调查这一快速发展的领域,将当前自由民主国家在传统媒体监管的更广泛视角下监管互联网内容的努力。正如我们将看到的,在当代自由民主国家中,有非常不同的国家方法来解决这个问题,在许多方面,新的互联网法规,无论是实际的还是拟议的,都是现有实践的延伸。我们的结论是,在美国的情况下,内容监管将很难在政治上实现,反垄断应被视为一种替代方案。在所有自由民主国家,媒体监管都是一个敏感而有争议的话题。美国宪法第一修正案保护言论自由,欧盟和欧洲委员会的各种法律文书以及《欧洲人权公约》也保障媒体自由。言论自由在规范上被认为是自由民主正常运作的关键

Misinformation, Disinformation, and Online Propaganda 错误信息、虚假信息和网络宣传
Pub Date : 2020-08-31 DOI: 10.1017/9781108890960.003
A. Guess, Benjamin A. Lyons
Not long ago, the rise of social media inspired great optimism about its potential for flattening access to economic and political opportunity, enabling collective action, and facilitating new forms of expression. Its increasingly widespread use ushered in a wave of commentary and scholarship seeking to meld wellestablished bodies of knowledge on mass media, economics, and social movements with the affordances of this new communication technology. Several political upheavals and an election later, the outlook in both the popular press and scholarly discussions is decidedly less optimistic. Facebook and Twitter are more likely to be discussed as incubators of “fake news” and propaganda than as tools for empowerment and social change. The resulting research focus has changed, too, with scholars looking to earlier literatures on misperceptions and persuasion for insight into the challenges of the present. The terms “misinformation,” “disinformation,” and “propaganda” are sometimes used interchangeably, with shifting and overlapping definitions. All three concern false or misleading messages spread under the guise of informative content, whether in the form of elite communication, online messages, advertising, or published articles. For the purposes of this chapter, we define misinformation as constituting a claim that contradicts or distorts common understandings of verifiable facts. This is distinct conceptually from rumors or conspiracy theories, whose definitions do not hinge on the truth value of the claims being made. Instead, rumors are understood as claims whose power arises from social transmission itself (Berinsky 2015). Conspiracy theories have specific characteristics, such as the belief that a hidden group of powerful individuals exerts control over some aspect of society (Sunstein and Vermeule 2009).
不久前,社交媒体的兴起激发了人们对其潜力的极大乐观,人们认为它有可能使经济和政治机会变得平坦,使集体行动成为可能,并促进新的表达形式。它的日益广泛使用引发了一波评论和学术浪潮,这些评论和学术试图将大众传媒、经济学和社会运动方面的成熟知识体系与这种新通信技术的功能融合在一起。几次政治动荡和选举之后,大众媒体和学术讨论的前景显然不那么乐观。Facebook和Twitter更有可能被视为“假新闻”和宣传的孵化器,而不是赋权和社会变革的工具。由此产生的研究焦点也发生了变化,学者们着眼于早期关于误解和说服的文献,以洞察当前的挑战。“错误信息”、“虚假信息”和“宣传”这三个词有时可以互换使用,定义也在不断变化和重叠。这三者都涉及在信息内容的幌子下传播的虚假或误导性信息,无论是以精英交流、在线信息、广告还是发表文章的形式。为了本章的目的,我们将错误信息定义为构成与可验证事实的共同理解相矛盾或扭曲的主张。这在概念上不同于谣言或阴谋论,谣言或阴谋论的定义并不取决于所提出的主张的真实价值。相反,谣言被理解为其力量来自社会传播本身的主张(Berinsky 2015)。阴谋论具有特定的特征,例如相信一个隐藏的强大个人团体对社会的某些方面施加控制(Sunstein和Vermeule 2009)。

Democratic Creative Destruction? The Effect of a Changing Media Landscape on Democracy 民主创造性破坏?不断变化的媒体格局对民主的影响
Pub Date : 2020-08-31 DOI: 10.1017/9781108890960.008
R. Nielsen, R. Fletcher
The move to a more digital, more mobile, and more platform-dominated media environment represents a change to the institutions and infrastructures of free expression and a form of “democratic creative destruction” that challenges incumbent institutions, creates new ones, and in many ways empower individual citizens, even as this change also leaves both individuals and institutions increasingly dependent on a few large US-based technology companies and subjects many historically disadvantaged groups to more abuse and harassment online. That is the argument we advance in this chapter, where we will aim to step away from assessing the democratic implications of the Internet on the basis of individual cases, countries, or outcomes to focus on how structural changes in the media are intertwined with changes in democratic politics. We will set aside considerations of (important) individual phenomena like the Arab Spring, the indignados movement, and #MeToo, or (important) individual outcomes like the 2014 Indian general elections, the UK (Brexit) referendum on EU membership, or the 2016 US presidential elections, and instead identify a few key changes at the institutional level and the individual level that are part and parcel of the rise of digital media and discuss how this rise is in turn changing the institutions and infrastructures that enable free expression. Inspired by James Webster (2014) and his work on structuration, we examine structural change by considering the interplay between institutional change on the supply side and aggregate individual-level behavior on the demand side. We will do so through the lens of news, first the news media as an institution and second news as part of how individual citizens engage with public life. We focus on news as one of several key aspects of democratic politics, key to how we imagine it in its ideal forms and key to how we realize it imperfectly in practice. The structural changes we analyze are not dictated by technology but
向更数字化、更移动化、更以平台为主导的媒体环境的转变,代表了自由表达的制度和基础设施的变化,也是一种“民主创造性破坏”的形式,它挑战现有的制度,创造新的制度,并在许多方面赋予公民个人权力,尽管这种变化也使个人和机构越来越依赖少数几家美国大型科技公司,并使许多历史上处于劣势的群体在网上受到更多的虐待和骚扰。这就是我们在本章中提出的论点,我们的目标是在个别案例、国家或结果的基础上评估互联网的民主含义,而不是关注媒体的结构变化如何与民主政治的变化交织在一起。我们将不考虑(重要的)个别现象,如阿拉伯之春、愤怒者运动和#MeToo,或(重要的)个别结果,如2014年印度大选、英国退欧公投或2016年美国总统大选。而是在制度层面和个人层面找出数位媒体崛起的关键变化,并讨论数位媒体的崛起如何反过来改变使言论自由得以实现的制度和基础设施。受詹姆斯·韦伯斯特(James Webster, 2014)及其结构化研究的启发,我们通过考虑供给侧制度变革与需求侧个人总体行为之间的相互作用来研究结构性变化。我们将通过新闻的镜头来做到这一点,首先是作为一个机构的新闻媒体,其次是作为公民个人如何参与公共生活的一部分的新闻。我们将新闻视为民主政治的几个关键方面之一,是我们如何想象其理想形式的关键,也是我们如何在实践中不完美地实现它的关键。我们分析的结构变化不是由技术决定的,而是

Online Political Advertising in the United States 美国的网络政治广告
Pub Date : 2020-08-31 DOI: 10.1017/9781108890960.007
E. Fowler, Michael M. Franz, Travis N. Ridout
Digital political advertising comes inmany forms, appears in amyriad of places, and can be targeted in many more ways than traditional television advertising. At its most basic, digital political advertising is interactive content placed for a fee. It includes display advertising (images, audio, or video) and search advertising (based on keyword search behavior); the goal may be to build supporter distribution lists, to fundraise for a candidate, party, or specific political cause, to persuade, or to increase name recognition and distribute information. Paid political ads can appear as banners (across the top of the page), as page takeovers, on the side of a webpage or news feed, in mobile apps, or in social media feeds where viewers can interact, like, or share them, further disseminating paid content organically. Some online ads feature call-to-action buttons and some auto-play as pre-roll advertising, appearing before consumers can continue their online activity. Some can be skipped and others will not allow further action until the ad finishes playing. According to Borrell Associates, digital advertising made up a small fraction (less than 1 percent, $71million) of political ad spending in the United States in 2014 but was projected to comprise a fifth of spending (20.1 percent, $1.8 billion) in 2018 (Borrell Associates 2018). Although digital advertising in campaigns has been around for a while and has been a growth market for several cycles now, it has long been overlooked by scholars, especially in comparison to traditional television advertising, for which there is a long and robust literature (see Fowler, Franz, and Ridout 2016), and even organic social media content, for which there is burgeoning research (Borah 2016; Bode et al. 2016). The lack of research on paid online advertising stems, in large part, from the difficulty in tracking the placement of and spending on online ads on websites, in apps, and on social media. Unlike television, where commercial tracking data has been available for two decades, systematic commercial tracking of digital advertising is very new, and until the aftermath of the 2016
数字政治广告有多种形式,出现在无数的地方,比传统的电视广告有更多的针对性。最基本的是,数字政治广告是付费投放的互动内容。它包括展示广告(图像、音频或视频)和搜索广告(基于关键字搜索行为);目标可能是建立支持者分布名单,为候选人、政党或特定的政治事业筹集资金,说服或提高知名度和传播信息。付费政治广告可以以横幅(在页面顶部)的形式出现,也可以作为页面接管,出现在网页或新闻动态的侧面,出现在移动应用程序中,或者出现在社交媒体动态中,浏览者可以与之互动、点赞或分享,从而进一步有机地传播付费内容。一些在线广告以号召按钮和一些自动播放的广告为特色,在消费者继续他们的在线活动之前出现。有些可以跳过,有些则不允许进一步操作,直到广告播放完毕。根据博雷尔协会的数据,2014年,数字广告占美国政治广告支出的一小部分(不到1%,7100万美元),但预计到2018年将占支出的五分之一(20.1%,18亿美元)(博雷尔协会2018年)。尽管竞选活动中的数字广告已经存在了一段时间,并且现在已经成为几个周期的增长市场,但长期以来一直被学者们所忽视,特别是与传统电视广告相比,传统电视广告有悠久而强大的文献(见Fowler, Franz, and Ridout 2016),甚至有机社交媒体内容,也有新兴的研究(Borah 2016;Bode et al. 2016)。在很大程度上,缺乏对付费在线广告的研究,是因为很难追踪在线广告在网站、应用程序和社交媒体上的投放和支出。在电视上,商业跟踪数据已经存在了20年,而数字广告的系统商业跟踪是非常新的,直到2016年大选之后

Facts and Where to Find Them: Empirical Research on Internet Platforms and Content Moderation 事实及其来源:互联网平台与内容监管的实证研究
Pub Date : 2019-12-16 DOI: 10.1017/9781108890960.011
Daphne Keller, P. Leerssen
Reliable information about platforms’ content removal systems was, for many years, hard to come by. But data and disclosures are steadily emerging as researchers focus on the topic and platforms ramp up their transparency measures, including both self-regulatory efforts as well as disclosures required by law. This essay reviews the current and likely future sources of information. First, we discuss disclosures from platforms and other participants in content moderation, such as users and governments. Second, we discuss independent research from third parties such as academics and journalists, including data analysis, interviews and surveys. Finally, before concluding the essay, we list specific questions and areas for future empirical research.
多年来,很难获得有关平台内容删除系统的可靠信息。但随着研究人员对这一话题的关注,以及平台加大透明度措施(包括自我监管努力和法律要求的披露),数据和披露正在稳步涌现。这篇文章回顾了当前和未来可能的信息来源。首先,我们讨论来自平台和其他内容审核参与者(如用户和政府)的披露。其次,我们讨论来自第三方(如学者和记者)的独立研究,包括数据分析、访谈和调查。最后,在总结本文之前,我们列出了未来实证研究的具体问题和领域。
