[TLDR: Ever engaged with one social media post and suddenly your whole feed looks the same? That’s no coincidence – it’s the algorithm at work. What we pause to watch, click or like tells the system what to show us next. Over time, this can colour what we see – sometimes positively, sometimes not – possibly shaping how we think, and influences what we believe. Our feeds are an algorithm’s best guess at keeping us hooked, but not necessarily a reflection of reality. This article unpacks how social media’s engagement loop can trap us in echo chambers and how to scroll with intention so the algorithm works for us, not the other way around.]

Decoding Your Feed: The Algorithm’s Take on “Normal”
Ever noticed how a simple ‘like’ can quickly fill your feed with hours of similar content? That’s algorithms at work, constantly curating what it thinks you’ll enjoy, creating the illusion that you’re seeing what “everyone” is thinking or doing. Algorithms prioritise engagement, this is why some trends have gone viral, even if they encourage dangerous behaviour.
Think about the Tide Pod Challenge in 2018 which dared users to consume laundry pods. The trend landed American children in hospitals.4 Another concerning trend was the #A4waist Challenge which promoted unhealthy ideals of body image by challenging users to measure their waist with an A4 paper.5
But what appears online isn’t always a true reflection of reality. When certain messages keep appearing, they can quietly distort our sense of what’s “popular” or “normal”, and this is particularly concerning when it comes to risky behaviours. While the vast majority of our population remains drug-free, 58% of youths in Singapore are exposed to drug abuse content on social media. 1 Long-term exposure to such content can encourage more casual attitudes toward harmful behaviour, making it seem more common or acceptable than it actually is.
Algorithms cannot evaluate content critically, but we can. The next time our feed starts shaping our perception of what’s “normal,” pause and ask: is this a true reflection of reality, or simply algorithms amplifying content that momentarily caught our attention?
The Algorithm’s Playbook: How Your ‘For You Page’ Gets Built
Social media thrives off engagement. Every click, like, comment, share or even lingering pause signals interest. These datapoints help predict future engagement: “This user liked a video on cats, so they’ll probably like these 10 other cat videos.”
This can be great for discovering new things or finding inspiration, like a new restaurant, fan theories on the hottest sci-fi show, or even empowering trends like the Ice Bucket Challenge that raised millions for ALS patients and is returning to raise mental health awareness.2 However, it can also amplify harmful content normalising drug abuse or dangerous online challenges like Subway Surfing.3
You or Your Algorithm?

The thing is, algorithms can only analyse our digital behaviour, not our intentions. A ‘like’ could be from a slip of finger. Sharing a video about drug abuse could be from shock, not because we resonate with it.
Here’s the kicker: algorithms will show similar content regardless of how we feel about it, just so we keep scrolling. This is how we become trapped in echo chambers. It’s hard to break out of these loops and because we naturally look to our peers for social cues on what’s normal, acceptable or even cool especially in our teens and twenties, it’s easy to overestimate how common certain behaviours are.
Imagine if a new challenge involving drug abuse were to emerge.
A Quick Guide to Smart Scrolling
While we can’t change how algorithms work, understanding their influence is key. To navigate these influences, consider these three tips:
- Question what seems ‘normal’: Think critically about trends – ask ourselves if these are actually common, or are we just seeing such content repeatedly because the algorithm thinks we’re interested?
- Diversify our digital diet: Explore new topics intentionally. By searching for diverse perspectives, we can break repetitive cycles and signal to algorithms to show broader ranges of content.
- Understand the marketing strategies of companies: Be aware of content that makes risky behaviours look exciting, consequence-free, or socially rewarding. See through tactics that falsely glamourise vices like drug abuse. 6
These three tips can help us tell the difference between what’s genuinely valuable and what’s just trying to grab our attention. Think of it as mental self-defense: spotting subtle manipulation, resisting the pressure to conform and making conscious choices about what we watch, like, or share. Social media algorithms are designed to capture and hold our attention, but they don’t have to control our perceptions of reality. By questioning what we see, we transform from passive consumers into active curators of our own experience.
The outcome? We make sure social media works for us, not the other way around.
