That isn't laziness. It's your brain doing exactly what it was built to do.
Most buying decisions aren't made through careful comparison. They're made quickly, often in a few seconds, by a brain that is always looking for the easiest reasonable option. For brands, understanding this is one of the most useful things behavioural science has to offer. And there's a twist that surprises people: making your brand easy to choose doesn't mean making it dull.
The psychologist Daniel Kahneman popularised the idea, in his book Thinking, Fast and Slow, that we have two modes of thought. System 1 is fast, automatic and intuitive. It's what lets you recognise a friend's face or finish the phrase "fish and...". System 2 is slow, deliberate and effortful. It's what you use to fill in a tax return.
System 2 is tiring, so the brain rations it. We save it for decisions that feel unfamiliar or high-stakes and let System 1 handle everything else. Picking a sandwich, a shampoo or a streaming service almost always falls to System 1.
Which means the brand that wins is often not the one with the best argument. It's the one System 1 finds easiest to process.
Cognitive fluency describes how easy something feels to take in. When information is easy to process, we tend to like it more, trust it more and judge it as more likely to be true. When it feels like hard work, we become more sceptical.
One of the best-known studies on this comes from psychologists Adam Alter and Daniel Oppenheimer, published in 2006. They found that newly listed companies with easy-to-pronounce names outperformed companies with awkward names shortly after going public. According to Princeton's summary of the research, investing $1,000 in the ten most fluent names would have earned $333 more than investing it in the ten least fluent. The effect was strongest in the first days and weeks, and faded over time.
Nobody sensible would pick shares based on pronunciation. But investors, short on time and swamped with information, were clearly leaning on a feeling of ease. Shoppers do much the same thing in a supermarket aisle every day of the week.
Fluency is about how easily something is processed once it's in front of you. Mental availability, a term closely associated with Byron Sharp and Jenni Romaniuk of the Ehrenberg-Bass Institute, is about how easily a brand comes to mind when a need arises in the first place.
When someone thinks "I need a quick lunch" or "something to keep the kids busy on a rainy Sunday", a handful of brands pop into their head. Those brands start with an enormous advantage. Everything else has to work much harder simply to be considered.
Mental availability is built through memory links. The more often a brand is connected with particular buying moments, and the more consistently it presents itself, the faster it gets retrieved. That's why consistency matters so much. Each time a brand changes its look or its message, it risks weakening the links it has already built.
Heuristics are the mental shortcuts that let us make decent decisions quickly. A few of them turn up in shopping all the time.
Familiarity: "I know this one, so it's probably fine."
Recognition: given two options, we lean towards the one we've heard of.
Social proof: "Lots of people buy this, so it must be good."
Price as a signal: "It costs a bit more, so it's probably better quality."
These shortcuts aren't flaws in human thinking. They're how people cope with forty kinds of toothpaste. Back in the 1950s, the psychologist William Hick showed that the more options people are given, the longer they take to decide. Add a busy week, a hungry child and a phone buzzing in your pocket, and it's no surprise people reach for the option that asks the least of them.
So what does "easy to process" look like in practice? Usually it comes down to removing effort at every point where someone might hesitate.
Familiar packaging. When a pack keeps its core colours, shape and layout, regular buyers can find it in seconds. The classic cautionary tale is Tropicana's 2009 redesign in the US, which replaced its well-known orange-and-straw image with a generic glass of juice. Sales reportedly fell by around a fifth within two months and the old packaging was brought back. Shoppers hadn't stopped liking the juice. They just couldn't find it.
Simple messaging. One clear idea beats five clever ones. If a customer has to read a claim twice to understand it, most won't bother.
Recognisable brand assets. Colours, characters, sounds and taglines act as shortcuts back to the brand. They let people identify you at a glance, often before they've read a single word. Easy experiences. Websites that are simple to navigate, checkouts that don't ask for your life story and product ranges that make sense. Friction anywhere in the journey is an open invitation to go elsewhere.
This is where many brands get nervous. If the brain loves the familiar and the simple, surely the safe thing is to play it straight?
Not quite. Fluency is about how easy something is to process, which is a different question from how exciting it is. Some of the most creative brand work around is also the most fluent, because it sits on top of a consistent set of assets that people already know. A long-running brand character can appear in a completely new story every year and still be recognised instantly. The novelty lives in the idea. The ease comes from the familiar world around it.
Distinctiveness and fluency work hand in hand. A brand that looks like everyone else in its category isn't easy to choose. It's easy to confuse. Clear, ownable assets, used consistently, are what make a brand both memorable and effortless to pick out.
People are overloaded. More products, more messages, more decisions, and not much more time to make them. In that environment, the brand that takes the effort out of choosing has a real competitive advantage.
That doesn't mean stripping out personality. It means being clear about who you are, turning up the same way often enough that people learn it, and removing anything that makes choosing you harder than it needs to be.
The brain loves a shortcut. The smartest brands make sure they're the one it takes.
At Together, we use behavioural insight to help brands become easier to notice, easier to remember and easier to choose. If you'd like to find out where your brand might be creating unnecessary friction, get in touch.
What is cognitive fluency in marketing?
Cognitive fluency is how easy something feels to process. In marketing, brands that are easy to recognise, read and understand tend to be liked and trusted more, simply because they take less mental effort.
What is mental availability?
Mental availability is how easily a brand comes to mind in a buying situation. It's built by consistently linking the brand with relevant moments and needs over time, and it's closely associated with research from the Ehrenberg-Bass Institute.
Does making a brand easy to choose make it boring?
No. Fluency comes from familiar, consistent brand assets, while creativity can live in the ideas built on top of them. Brands that look like everyone else are harder to choose, not easier.
