Echo chamber (media)

From Wikipedia, the free encyclopedia

An echo chamber is "an environment where a person only encounters information or opinions that reflect and reinforce their own."[1]

In discussions of news media, an echo chamber refers to situations in which beliefs are amplified or reinforced by communication and repetition inside a closed system and insulated from rebuttal.[1] By participating in an echo chamber, people are able to seek out information that reinforces their existing views without encountering opposing views, potentially resulting in an unintended exercise in confirmation bias. Echo chambers may increase social and political polarization and extremism.[2]

The term is a metaphor based on an acoustic echo chamber, in which sounds reverberate in a hollow enclosure. Another emerging term for this echoing and homogenizing effect within social media communities on the Internet is cultural tribalism.[3]

Many scholars note the effects that echo chambers can have on citizens' stances and viewpoints, and specifically implications has for politics.[4] However, some studies have suggested that the effects of echo chambers are weaker than often assumed.[5]

Concept[]

The Internet has expanded the variety and amount of accessible political information. On the positive side, this may create a more pluralistic form of public debate; on the negative side, greater access to information may lead to selective exposure to ideologically supportive channels.[2] In an extreme "echo chamber", one purveyor of information will make a claim, which many like-minded people then repeat, overhear, and repeat again (often in an exaggerated or otherwise distorted form)[6] until most people assume that some extreme variation of the story is true.[7]

The echo chamber effect occurs online when a harmonious group of people amalgamate and develop tunnel vision. Participants in online discussions may find their opinions constantly echoed back to them, which reinforces their individual belief systems due to the declining exposure to other's opinions.[8] Their individual belief systems are what culminate into a confirmation bias regarding a variety of subjects. When an individual wants something to be true, they often will only gather the information that supports their existing beliefs and disregard any statements they find that are contradictory or speak negatively upon their beliefs.[9] Individuals who participate in echo chambers often do so because they feel more confident that their opinions will be more readily accepted by others in the echo chamber.[10] This happens because the Internet has provided access to a wide range of readily available information. People are receiving their news online more rapidly through less traditional sources, such as Facebook, Google, and Twitter. These and many other social platforms and online media outlets have established personalized algorithms intended to cater specific information to individuals’ online feeds. This method of curating content has replaced the function of the traditional news editor.[11] The mediated spread of information through online networks causes a risk of an algorithmic filter bubble, leading to concern regarding how the effects of echo chambers on the internet promote the division of online interaction.[12]

It is important to note that members of an echo chamber are not fully responsible for their convictions. Once part of an echo chamber, an individual might adhere to seemingly acceptable epistemic practices and still be further misled. Many individuals may be stuck in echo chambers due to factors existing outside of their control, such as being raised in one.[13]

Furthermore, the function of an echo chamber does not entail eroding a member's interest in truth; it focuses upon manipulating their credibility levels so that fundamentally different establishments and institutions will be considered proper sources of authority.[14]

Empirical research[]

However, empirical findings to clearly support these concerns are needed [15] and the field is very fragmented when it comes to empirical results. There are some studies that do measure echo chamber effects, such as the study of Bakshy et al. (2015).[16][17] In this study the researchers found that people tend to share news articles they align with. Similarly, they discovered a homophily in online friendships, meaning people are more likely to be connected on social media if they have the same political ideology. In combination, this can lead to echo chamber effects. Bakshy et al. found that a person's potential exposure to cross-cutting content (content that is opposite to their own political beliefs) through their own network is only 24% for liberals and 35% for conservatives.

However, there are other studies which contradict this. Some found that news reports are also shared if they don't align with the political believes.[18] Others found that people using social media are being exposed to more diverse sources than people not using social media.[19] In summation, it remains that clear and distinct findings are absent which either confirm or falsify the concerns of echo chamber effects.

Difficulties of researching processes[]

There are several reasons why empirical findings are so fragmented and unclear. First, there are some conceptual unclarities due to different definitions and the novelty of these phenomenons. Therefore, there are inconsistent measuring methods and usage of the concepts which means that studies aren't comparable. In addition to that, the data that is used in the empirical research isn't representative for the entire population, as Facebook users for example are more likely to be feminine and have a higher educational status than the average US population. Another problem is the aggregation bias where individually, effects are being measured, but when adapted to the population it can lead to ecological fallacy. Furthermore, social media platforms are continually changing their algorithmic filtering without making these algorithms public. This makes it difficult to get consistent and comparable results. Finally, most studies are done in the US, therefore in a two party system and can not be conferred to political systems with several different parties.[20]

Echo chambers vs epistemic bubbles[]

In recent years, closed epistemic networks have increasingly been held responsible for the era of post-truth and fake news.[21] However, the media frequently conflates two distinct concepts of social epistemology: echo chambers and epistemic bubbles.[14]

An epistemic bubble is an informational network in which important sources have been excluded by omission, perhaps unintentionally. It is an impaired epistemic framework which lacks strong connectivity.[22] Members within epistemic bubbles are unaware of significant information and reasoning.

On the other hand, an echo chamber is an epistemic construct in which voices are actively excluded and discredited. It does not suffer from a lack in connectivity; rather it depends on a manipulation of trust by methodically discrediting all outside sources.[23] According to research conducted by the University of Pennsylvania, members of echo chambers become dependent on the sources within the chamber and highly resistant to any external sources.[24]

An important distinction exists in the strength of the respective epistemic structures. Epistemic bubbles are not particularly robust. Relevant information has merely been left out, not discredited.[25] One can ‘pop’ an epistemic bubble by exposing a member to the information and sources that they have been missing.[13]

Echo chambers, however, are incredibly strong. By creating pre-emptive distrust between members and non-members, insiders will be insulated from the validity of counter-evidence and will continue to reinforce the chamber in the form of a closed loop.[23] Outside voices are heard, but dismissed.

As such, the two concepts are fundamentally distinct and cannot be utilized interchangeably. However, one must note that this distinction is conceptual in nature, and an epistemic community can exercise multiple methods of exclusion to varying extents.

Further information: filter bubble

A filter bubble – a term coined by internet activist Eli Pariser – is a state of intellectual isolation that allegedly can result from personalized searches when a website algorithm selectively guesses what information a user would like to see based on information about the user, such as location, past click-behavior and search history. As a result, users become separated from information that disagrees with their viewpoints, effectively isolating them in their own cultural or ideological bubbles. The choices made by these algorithms are not transparent.

Further information: homophily

Homophily is the tendency of individuals to associate and bond with similar others, as in the proverb "birds of a feather flock together". The presence of homophily has been detected in a vast array of network studies.

Both echo chambers and filter bubbles relate to the ways individuals are exposed to content devoid of clashing opinions, and colloquially might be used interchangeably. However, echo chamber refers to the overall phenomenon by which individuals are exposed only to information from like-minded individuals, while filter bubbles are a result of algorithms that choose content based on previous online behavior, as with search histories or online shopping activity.[16] It is equally important to understand that although similar, homophily and echo chambers are not the same either.

Implications of echo chambers[]

Online communities[]

Online social communities become fragmented by echo chambers when like-minded people group together and members hear arguments in one specific direction with no counter argument addressed. In certain online platforms, such as Twitter, echo chambers are more likely to be found when the topic is more political in nature compared to topics that are seen as more neutral.[26] Social networking communities are communities that are considered to be some of the most powerful reinforcements of rumors[27] due to the trust in the evidence supplied by their own social group and peers, over the information circulating the news.[28][29] In addition to this, the reduction of fear that users can enjoy through projecting their views on the internet versus face-to-face allows for further engagement in agreement with their peers.[30]

This can create significant barriers to critical discourse within an online medium. Social discussion and sharing can potentially suffer when people have a narrow information base and do not reach outside their network. Essentially, the filter bubble can distort one's reality in ways which are not believed to be alterable by outside sources.[31]

Offline communities[]

Many offline communities are also segregated by political beliefs and cultural views. The echo chamber effect may prevent individuals from noticing changes in language and culture involving groups other than their own. Online echo chambers can sometimes influence an individual's willingness to participate in similar discussions offline. A 2016 study found that "Twitter users who felt their audience on Twitter agreed with their opinion were more willing to speak out on that issue in the workplace".[10]

Group polarisation can occur as a result of growing echo chambers. The lack of external viewpoints and the presence of a majority of individuals sharing a similar opinion or narrative can lead to a more extreme belief set. Group polarisation can also aid the current of fake news and misinformation through social media platforms.[32] This can extend to offline interactions, with data revealing that offline interactions can be as polarising as online interactions (Twitter), arguably due to social media-enabled debates being highly fragmented.[33]

Examples[]

Ideological echo chambers have existed in many forms, such as:

  • The McMartin preschool trial coverage was criticized by David Shaw in his 1990 Pulitzer Prize winning articles, "None of these charges was ultimately proved, but the media largely acted in a pack, as it so often does on big events, and reporters' stories, in print and on the air, fed on one another, creating an echo chamber of horrors."[34] Shaw stated that this case "exposed basic flaws" in news organizations such as "Laziness. Superficiality. Cozy relationships" and "a frantic search to be first with the latest shocking allegation". His mention of "Reporters and editors often abandoned" journalistic principles of "fairness and skepticism" and "frequently plunged into hysteria, sensationalism and what one editor calls 'a lynch mob syndrome'" shows the effect of such an echo chamber and how it alters the coverage of specific types of media.
  • The conservative radio host, Rush Limbaugh, and his radio show was categorized as an echo chamber in the first empirical study concerning echo chambers by researchers Kathleen Hall Jamieson and Frank Capella in their book: Echo Chamber: Rush Limbaugh and the Conservative Media Establishment (2008)[35]
  • The Clinton-Lewinsky scandal reporting was chronicled in Time magazine's 16 February 1998 "Trial by Leaks" cover story[36] "The Press And The Dress: The anatomy of a salacious leak, and how it ricocheted around the walls of the media echo chamber" by Adam Cohen.[37] This case was also reviewed in depth by the Project for Excellence in Journalism in "The Clinton/Lewinsky Story: How Accurate? How Fair?"[38]
  • A New Statesman essay argued that echo chambers were linked to the UK Brexit referendum.[39]
  • The subreddit /r/incels and other online incel communities have also been described as echo chambers.[40][41][42]
  • Discussion concerning opioid drugs and whether or not they should be considered suitable for long-term pain maintenance.[43]
  • The 2012 presidential election was described as an echo chamber, as information was exchanged primarily among individuals with similar political and ideological views.[44]

However, since the creation of the internet, scholars have been curious to see the changes in political communication.[45] Due to the new changes in information technology and how it is managed, it is unclear how opposing perspectives can reach common ground in a democracy.[46] The effects seen from the echo chamber effect has largely been cited to occur in politics, such as Twitter[47] and Facebook during the 2016 presidential election in the United States.[17] Some believe that echo chambers played a big part in the success of Donald Trump in the 2016 presidential elections.[48]

Countermeasures[]

From media companies[]

Some companies have also made efforts in combating the effects of an echo chamber on an algorithmic approach. A high-profile example of this is the changes Facebook made to its "Trending" page, which is an on-site news source for its users. Facebook modified their "Trending" page by transitioning from displaying a single news source to multiple news sources for a topic or event.[49] The intended purpose of this was to expand the breadth of news sources for any given headline, and therefore expose readers to a variety of viewpoints. There are startups building apps with the mission of encouraging users to open their echo chambers, such as unFound.news.[50] Another example is a beta feature on BuzzFeed News, called "Outside Your Bubble".[51] This experiment adds a module at the bottom of BuzzFeed News articles to show reactions from various platforms, like Twitter, Facebook, and Reddit. This concept aims to bring transparency and prevent biased conversations, diversifying the viewpoints their readers are exposed to.[52]
