Cognitive load has become the web design equivalent of “eat your vegetables”—everyone knows it’s important, and we all try to do it, but sometimes it feels like we’re trying to stuff an entire kale salad into a single bite.
Sure, reducing cognitive load seems like the responsible thing to do, but is making everything simpler the best way forward?
Or, are we accidentally throwing the design baby out with the bathwater, stripping away complexity that could actually enhance the user experience?
It’s easy to fall into the trap of thinking that if we just reduce the number of choices, eliminate distractions, and simplify everything down to a perfectly clean interface, we’ll have the “perfect” site.
But is this the right approach every time? Let’s take a closer look and see if we’ve been too quick to assume that “less is more” in all cases.
The Case for Reducing Cognitive Load: Simplicity, But Not Too Simple
Before we dive into the murky waters of complexity, let’s take a moment to appreciate why cognitive load reduction is so appealing.
The theory, first introduced by John Sweller in the 1980s, tells us that our brains have a limited amount of mental bandwidth. When we’re bombarded with too much information, it can be overwhelming and, let’s face it, exhausting. In web design, this means reducing confusion by making sites easier to navigate and providing users with a clear path forward.
The logic is simple: less mental effort = happier users. And it’s hard to argue with that. After all, we all want our users to feel like they’re on a smooth, intuitive journey through our websites.
We want them to get where they need to go without feeling like they need to call in a team of detectives to figure out how to book a flight or buy a pair of socks.
But what if we’ve been so focused on reducing cognitive load that we’ve been over-simplifying? What if in our efforts to make things “easy,” we’ve stripped away something that could actually make the experience more meaningful, engaging, or even fun?
Finding Space for Complexity: Why Sometimes More is More (And That’s Okay)
Hold onto your hats, because here comes the controversial bit: sometimes, a little bit of complexity is exactly what a design needs.
Sure, the idea of a clean, minimal interface sounds dreamy—like a spa day for your brain—but a little mental effort can be surprisingly rewarding, especially if there’s a sense of accomplishment or engagement involved.
Let’s take Amazon as an example. It’s far from minimalist. In fact, it’s a design jungle. There are product recommendations, ads, reviews, and enough buttons to make you feel like you’re trying to navigate an ancient labyrinth. But here’s the thing: it works.
The cognitive load is high, yes, but it’s worth it because Amazon knows that people are there for one reason: they’re looking for something specific. They’re ready to engage, and that’s why they don’t mind the mental gymnastics involved in searching for the perfect pair of running shoes. They’re not afraid of a little complexity because the payoff is huge.
And let’s be real—sometimes you want a bit of a mental workout. If you walk into a bookstore, you don’t expect the shelves to be empty with just one book waiting for you, do you? You want choice, you want variety, and sometimes, a little bit of effort to explore the shelves is exactly what makes the experience enjoyable.
Embracing User Engagement: Giving People the Space to Explore (And Maybe Get Lost a Little)
Speaking of exploration, did you know that users actually like engaging with content that makes them think?
Sure, we often assume that everyone is a busy, distracted user who wants everything handed to them on a silver platter, but in reality, some users actively enjoy a bit of complexity. It’s like the difference between a “pick-your-own-adventure” book and one that just tells you how the story ends—one is far more fun, right?
Think about those interactive websites where users get to make decisions, follow storylines, or dive deeper into layers of information. These designs require users to think and engage, and they’re actually more fun for it. Users feel like they have control, and that sense of agency can be super satisfying.
So, what’s the takeaway here? Sometimes, just like with a good mystery novel, a little complexity can keep users hooked. They’ll stay engaged and invested because there’s something more to discover with each click.
A little challenge can be a good thing—it keeps the brain from getting too bored, and it adds an element of excitement to the experience.
Striking the Right Balance: Simplicity and Complexity Can Coexist (Like Peanut Butter and Jelly)
The truth is, the best designs don’t have to be purely minimalist or overly complex—they just need to find the right balance between simplicity and richness. Think of it like making a sandwich: you don’t just throw peanut butter on bread and call it a day (well, unless you’re in a rush, which we all do sometimes).
But when you add a little jelly, maybe some honey, and a sprinkle of creativity, that’s where the magic happens.
Take Apple, for example. Their design is clean and minimal, but it doesn’t shy away from complexity where it makes sense. The user interface is sleek and simple, but there’s so much depth behind it. You can customize settings, explore advanced features, and really get into the nitty-gritty of what the product can do.
Apple understands that the user experience can be both straightforward and rich. It’s about giving users the option to dive deep when they want to, but still guiding them through a clean, intuitive interface when they need it.
That’s the sweet spot in design: knowing when to give users simplicity and when to allow for complexity. You don’t need to choose between the two. It’s about being intentional and thoughtful in how complexity is introduced, ensuring that users feel in control and don’t get overwhelmed.
Cognitive Load Isn’t One-Size-Fits-All (And That’s a Good Thing)
At the end of the day, cognitive load is like an outfit—it’s all about what suits the situation. Yes, reducing cognitive load can be a lifesaver when you need to guide users through a simple task, like booking a flight or making a quick purchase.
But it’s also important to recognize that not all cognitive load is bad. A bit of mental effort can lead to a more engaging and satisfying experience, especially when the user is involved in something they care about or enjoy.
So, the next time you’re designing a site or an app, ask yourself: What’s the experience we’re trying to create here? Is it one where users can easily complete a task, or is it one where they can explore, engage, and learn along the way?
Simplification isn’t always the best choice. Sometimes, a little complexity makes things more interesting—and that’s perfectly okay.
Ultimately, we’re all trying to create designs that connect with users in meaningful ways. And sometimes, the best way to do that is not by stripping everything down, but by adding just the right amount of depth and engagement.
It’s like a good conversation—simple doesn’t always mean better, and a little complexity can lead to some of the most rewarding experiences.
So let’s not be afraid to get a little creative and embrace the beauty of both simplicity and complexity. After all, they can live happily together—like peanut butter and jelly.
