Pick any of the big topics of the day- referendum, climate change or even Trump’s re-election– and wander online. What one is likely to find is radical polarisation- different groups of people living in different worlds, populated with utterly different facts (Nguyen, 2019).
Enter filter bubbles and echo chambers: the powerful but often overlooked phenomena that influences not only what we see but what we believe and trust.
In today’s digitally driven world, navigating through a sea of information has become a challenge of unprecedented proportions, with discussions on pivotal topics inevitably encountering radical polarisation. This phenomenon is propelled by filter bubbles and echo chambers. Therefore, as we dive into an intricate web of digital information, it is imperative to understand how these forces operate and their far-reaching implications on our collective consciousness.
Defining and Clarifying
Let’s begin by clarifying what ‘filter bubbles’ and ‘echo chambers’ are referring to.
Filter bubbles, a potent metaphor coined by Pariser (2011), are personalised information ecosystem created by algorithms. These cocoon individuals in a world tailored to their preferences, shielding them from dissenting opinions. Importantly, social media platforms, employing advanced algorithms, play a pivotal role in facilitating this phenomenon. By carefully curating content based on user behaviour, platforms skilfully create an environment where users are exposed primarily to information that aligns with their existing beliefs, in turn being more inclined to spend time on these sites (Mims, 2017).
However, it doesn’t just stop there. Echo chambers, as first articulated by Sunstein (2017), take this concept further, suggesting the creation of bounded spaces that magnify messages and insulate them from rebuttal. The concept of echo chambers therefore opens suggestions that the underlying issue, may not lie in what people hear, but rather in whom they choose to believe. In echo chambers, insiders come to distrust everybody on the outside creating a closed loop of information that reinforces pre-existing beliefs.
So, the next question is how do these ‘bubbles’ and ‘chambers’ form?
It’s 2am, you are lying on your bed, phone in hand, scavenging the depths of TikTok. Post after post, video after video, eyes almost shut, you continue to scroll through hundreds of videos.
Whilst to us it seems mindless and almost habitual, all whilst we do this, TikTok’s algorithm, a veritable mastermind, employs a multi-phase approach to create the perfect echo chamber.
Let’s break it down:
The first phase, monitoring app activity, starts from the moment a user downloads the app. Every like, comment, follow, and interaction is meticulously analysed to build a personalised ‘For You’ page. This page becomes a customised stream of content, carefully selected to align with all previous interactions.
The second phase delves into content information. In addition to user interactions, TikTok’s algorithm scrutinises captions and hashtags associated with each post. Again, this analysis significantly influences the echo chamber, particularly in a political context, that individuals are embedded in.
The third phase considers device settings. Factors such as location, language, device type and repeated viewership play a crucial role in determining the type of videos that populate a user’s ‘For You’ page. This level of customisation ensures that users are continuously exposed to content that not only aligns with their preference, but further confirms these, deepening their immersion into the chamber.
Hence, TikTok characterised by its unique and astute algorithm, has emerged as a prominent example and formidable force in discussions about filter bubbles and echo chambers. It has evolved into a vital platform for political messaging and information consumption, particularly among the younger generations. Importantly, politicians have swiftly recognised this potential, utilising distinct features to bolster their influence and reinforce trust among like-minded followers. This marks a significant shift in how politicians engage with audience, capitalising on the power of echo chambers (Valenzula, 2022).
But are they responsible?
In the current digital age, the phenomenon of information polarisation has gained significant attention. The question that looms larger is: to what extent are filter bubbles and echo chambers responsible for this polarisation?
While the existence of filter bubbles and echo chambers is undeniable, their role in societal polarisation remains a topic of rigorous debate among scholars.
So, let’s break down the debate.
Filter bubbles and echo chambers: A Closer Look
Advocates of the view that filter bubbles and echo chambers primarily drive information polarisation emphasise the transformative impact of digital algorithms on societies information consumption. Eli Pariser, a prominent voice in this discourse, argues that it is personalised content algorithms which cocoon users within an environment that reinforce existing beliefs, therefore effectively sheltering individuals from diverse perspectives.
Pariser’s work, notably his book “The Filter Bubble: What the Internet is Hiding from You” and his TED talk “Beware Filter Bubbles”, highlight how these algorithms subtly edit the web, resulting in users being exposed only to information that aligns with preconceived notions. He contends that this isolation prevents meaningful connections and fosters passive consumption of information, likening it to ‘information junk food’.
Furthermore, he draws on Eric Schmidt’s statement which acknowledges that tailored content has become a dominant mode of consumption, blurring the line between unbiased information and curated content. Netflix researchers add that this customisation represents an ongoing struggle between one’s present and future self, perpetuating the cycle of reinforcement.
Selective Exposure: The Psychological Underpinnings
Affirming Pariser’s perspective, Beam et al (2018) delve into the psychological construct of selective exposure, asserting that individuals naturally seek information that affirms their existing beliefs. This inclination stems from cognitive dissonance, an innate protective mechanism that shields individuals from discomfort of challenging established viewpoints. Hence, algorithms employed by news aggregators and social media platforms capitalise on this tendency, perpetuating a cycle where individuals are predominantly exposed to information that mirrors their existing beliefs.
Bruns’ perspective: A Nuanced View
However, not everyone is convinced by Pariser. Axel Bruns, another prominent figure in this field, brings a nuanced perspective to this debate, cautioning against oversimplifying the issue. He contends that assigning exclusive blame on filter bubbles and echo chambers fails to account for the agency of individuals in shaping their information environment. Bruns suggests that these phenomena serve as amplifiers rather than originators of polarisation, intensifying existing divisions rooted in socio-political rifts.
Bruns also highlights the complexity of the digital information ecosystem, where various components, including search engines, social media platforms and new aggregators, contribute to content exposure. While algorithms undoubtedly play a role, user agency in selecting sources cannot be overlooked. Moreover, the role of cognitive biases like confirmation bias and motivated reasoning operates independently of algorithmic recommendations. Garrett (2009), challenges the binary view of selective exposure, emphasising how different opinions within a news story influence an individual’s use of that information.
Historical precedents: Echo chambers through time
Bruns also draws critical attention to historical precedents, underscoring that polarisation and ideological divisions are not unique to the digital age. Partisan newspapers of the 18th and 19th centuries serve as powerful examples of echo chambers long before algorithms shaped our information landscape.
Popping the bubble & escaping the chamber
Whether or not you are convinced of filter bubbles and echo chambers being responsible for societies polarisation, it is undeniable that these mechanisms are ever-present. Therefore, to counter their influence is critical.
Diversifying information sources:
To counter the influence of filter bubbles and echo chambers, actively seeking diverse information sources is paramount (Sunstein, 2017). This deliberate exposure to varying viewpoints challenges entrenched beliefs, leading to a more comprehensive understanding of complex issues, from politics to news. Such practices foster intellectual growth and dismantle the insularity of echo chambers (Pariser, 2011).
Media literacy and critical thinking:
Media literacy and critical thinking skills are also indispensable tools for navigating the digital information-rich landscape (Wineburg & McGrew, 2017). The ability to discern reliable sources, fact-check information and critically analyse content is imperative. Educational initiatives and awareness campaigns promoting media literacy empower individuals to confidently navigate the digital realm. These skills collectively contribute to breaking down echo chambers and facilitating meaningful discourse (Grizzle et al, 2017)
Conclusively, echo chambers and filter bubbles subtly shape our information consumption in today’s digital landscape. While they contribute to polarisation, Bruns’ nuanced stance urges a broader perspective, considering the intricate interplay of elements in our information ecosystem. Therefore, while filter bubbles and echo chambers are factors, appreciating the complexity of the issue provides a more accurate assessment of polarisation. However, as we move forward, a critical engagement with information is paramount and dismantling division in favour of diverse perspectives becomes a shared responsibility.
