Social media algorithms are like the wizards behind the curtain—pulling strings, shuffling data, and shaping the conversations we see without most of us even noticing. These algorithms are everywhere, deciding what shows up on your Instagram feed, which tweets pop up in your timeline, and even what political videos autoplay on YouTube. But in the grand scheme of things, their impact goes beyond just keeping us entertained or helping us reconnect with high school friends. They’re steering public opinion, and when it comes to political candidates, the effects can be downright seismic.
Understanding how these algorithms influence public opinion means diving into the murky waters of how they work, what they prioritize, and—crucially—how they affect our views on politics. And if there’s one thing that’s clear from the get-go, it’s this: algorithms don’t just reflect our preferences; they mold them, often subtly but sometimes with all the finesse of a sledgehammer.
At its core, a social media algorithm is a decision-making engine. It’s a piece of code designed to sift through mountains of data (your likes, comments, shares, how long you spend reading certain posts) and serve up content that aligns with what it thinks you want to see. Sounds harmless, right? But the thing is, when you mix algorithms with political content, it’s a whole different ball game. It’s not just about showing you cute puppy videos—it’s about reinforcing your political beliefs or nudging you toward a particular candidate, even if you don’t realize it’s happening.
Now, let’s take a step back and look at the bigger picture. Algorithms feed off engagement, and they prioritize content that generates more clicks, comments, and shares. This is where the rubber meets the road in terms of political influence. Content that stirs up strong emotions—anger, fear, outrage—tends to perform better than content that’s more neutral or balanced. Political posts that provoke these emotions are exactly what algorithms love to push to the top of your feed. The more people engage with a post, the more visibility it gains, and before you know it, a polarizing political opinion is reaching millions.
This leads us to the infamous echo chamber effect, where people are increasingly exposed to information that confirms their existing views. Algorithms are essentially designed to give users more of what they want, which sounds good in theory, but in practice, it can isolate people from opposing viewpoints. If you’ve ever wondered why your social media feed seems to be filled with people who think just like you, that’s the echo chamber at work. It’s not necessarily that everyone shares your opinions, but rather, the algorithm is feeding you content that aligns with what you already believe. This phenomenon is particularly dangerous in politics, where exposure to diverse opinions is critical for a functioning democracy.
The echo chamber effect can have a dramatic impact on elections. If voters are only exposed to one side of the argument, they’re more likely to view the opposing side as extreme, incompetent, or downright dangerous. In fact, research shows that echo chambers can lead to increased polarization, as people become more entrenched in their views and less willing to consider alternative perspectives. In the political world, where winning hearts and minds is everything, this kind of self-reinforcing feedback loop can be incredibly powerful.
But it’s not just echo chambers that are the problem. Algorithms also play favorites when it comes to what type of content they push to the top of the pile. Take, for example, the concept of virality. Content that goes viral—whether it’s a meme, a video, or a controversial political take—gets a big boost in visibility thanks to algorithms. The more people engage with it, the more it spreads, like wildfire through a dry forest. In the political realm, this often means that the most provocative, outrageous, or emotionally charged content gets the most attention. And let’s be real—reasoned, nuanced debate rarely goes viral.
This is where the danger of misinformation comes into play. Algorithms don’t differentiate between factual information and falsehoods—they only care about engagement. As a result, fake news can spread just as quickly, if not more so, than the truth. We saw this during the 2016 U.S. presidential election, where misinformation about candidates spread like a plague across social media platforms. In fact, one study from the Massachusetts Institute of Technology found that false stories on Twitter spread faster and reached more people than true ones, particularly when they were related to politics.
But algorithms don’t just amplify the loudest voices; they also have the power to silence others. Enter the world of shadowbanning and de-boosting. These terms might sound like something out of a dystopian novel, but they’re very real in today’s social media landscape. Shadowbanning occurs when a platform reduces the visibility of a user’s content without informing them. This can happen for a variety of reasons, but in the context of politics, it’s particularly concerning. Critics argue that social media companies are using these tactics to suppress certain political views, giving an unfair advantage to one side over the other.
Of course, not everything about algorithms is doom and gloom. Political campaigns have learned to harness the power of these digital gatekeepers to their advantage. Microtargeting, for example, is a strategy where political ads are tailored to specific groups of people based on their online behavior. This allows campaigns to deliver highly personalized messages that resonate with individual voters. If you’ve ever noticed an eerily specific political ad pop up on your social media feed, you’ve experienced microtargeting firsthand. It’s like digital whispering—campaigns can subtly sway your opinion without you even realizing it.
Nowhere is this more apparent than in the rise of political memes. What used to be a niche corner of the internet has become a full-blown battlefield in the world of political campaigns. Memes are funny, quick to consume, and highly shareable—qualities that make them ideal for spreading political messages. And algorithms absolutely love memes. Their visual nature, combined with their ability to provoke a strong emotional response, means that they’re often prioritized in users’ feeds. Political candidates and their supporters have become masters of the meme game, using humor and satire to subtly—or not so subtly—push their agendas.
But memes aren’t the only way political candidates are leveraging social media algorithms. Influencers, too, have become key players in the game. Social media stars with massive followings can sway public opinion with a single post, and political campaigns are increasingly partnering with these influencers to reach new audiences. Whether it’s a subtle endorsement or a full-blown campaign ad, influencers can help political candidates reach voters who might not otherwise engage with traditional political content. And because influencers’ posts are often promoted by algorithms, their reach can be enormous.
All of this begs the question: are algorithms biased? The short answer is yes, but not necessarily in the way you might think. Algorithms are created by humans, and as such, they can inherit the biases of their creators. This means that certain political ideologies or candidates may be inadvertently favored by the way an algorithm is designed. For example, a platform that prioritizes engagement might end up favoring more sensationalist political content, which tends to come from more extreme viewpoints. Similarly, if an algorithm’s training data is skewed toward a particular demographic, it might not accurately reflect the diversity of political opinions in the real world.
The influence of algorithms on political candidates isn’t just a domestic issue—it’s a global one. In countries around the world, social media algorithms have played a role in shaping political discourse. From the Brexit vote in the UK to the rise of populist leaders in India, algorithms have become powerful tools for political actors looking to sway public opinion. In some cases, this has led to increased political engagement, but in others, it has exacerbated polarization and division.
With all of this in mind, it’s important to ask: are algorithms helping or hurting democracy? On the one hand, they’ve made it easier for people to access information and engage with political content. On the other hand, they’ve created filter bubbles, spread misinformation, and amplified divisive voices. Some experts argue that algorithms are contributing to a decline in civic engagement, as people become disillusioned with the polarized, hyper-partisan content they see online. Others, however, believe that algorithms can be harnessed for good, by encouraging more thoughtful political conversations and helping people connect with candidates who align with their values.
So, what can be done to mitigate the negative effects of algorithms on political opinion? For starters, platforms need to be more transparent about how their algorithms work. Users should have a better understanding of why they’re seeing certain content and how their data is being used to shape their online experience. Additionally, there needs to be greater accountability when it comes to the spread of misinformation. Social media companies have made strides in this area, but there’s still a long way to go.
Ultimately, it’s up to all of us to be more aware of how algorithms are influencing our political views. By diversifying our social media feeds, engaging with different perspectives, and fact-checking the information we come across, we can start to take back control from the algorithms. And as governments around the world consider new regulations on social media platforms, we may soon see more efforts to rein in the power of algorithms.
The future of political campaigning in the age of algorithms is uncertain, but one thing is clear: social media isn’t going anywhere. As technology continues to evolve, so too will the ways in which algorithms shape public opinion. Whether this leads to a more informed, engaged electorate or a more divided, polarized one remains to be seen. But one thing’s for sure—algorithms will be pulling the strings, whether we like it or not.
