Your Marketing Was Built for a Customer Who Doesn't Exist

Most business owners test their marketing the same way: they read their own landing page and ask, "Would I fill in this form?"

That question is the most expensive mistake in marketing.

You know your product inside out. You've spent months thinking about positioning. You care deeply about the details that separate you from competitors. Your customer hasn't thought about you for a single second until they landed on your page. They'll give you about 54 seconds of attention before they leave. And according to Nielsen Norman Group's eye-tracking research, they'll read roughly 20% of the text on that page.

Your marketing was designed for a careful, rational evaluator. Your actual customer is a scanner with their thumb hovering over the back button.

A study involving 714 marketing executives, published in the Journal of Marketing Research, found that when marketers actively suppressed their personal preferences while predicting customer behaviour, their prediction errors decreased by more than 50%. Not a 10% refinement. Not a marginal improvement. They were wrong by half.

The Bias That Costs You Half Your Leads

Psychologists call it the false consensus effect: the tendency to overestimate how much other people share your views, preferences, and behaviours. It was first documented by Lee Ross in 1977, and it shows up everywhere. But marketing is where it does the most financial damage.

The American Marketing Association highlighted the CBS Copenhagen research showing that more than 70% of marketers project their personal preferences onto consumers. This isn't a rookie mistake. The study tested experienced marketing executives and found the bias was just as strong in senior leaders as in juniors.

Here's why it's so persistent: you can't unknow what you know. Daniel Kahneman calls this the curse of knowledge. Once you understand your own product, your own industry, your own pricing structure, you lose the ability to see your business through the eyes of someone encountering it for the first time. Every feature seems obvious. Every benefit seems self-evident. Every page of your website seems clear.

It isn't. Not to them.

The uncomfortable implication is that your expertise is actively working against your ability to market it. The better you understand your product, the worse you become at explaining it to someone who doesn't.

You Build for System 2. They Buy with System 1.

Kahneman's distinction between System 1 (fast, automatic, intuitive) and System 2 (slow, deliberate, analytical) thinking is one of the most commercially useful frameworks in psychology. It explains the projection problem perfectly.

Marketers are System 2 thinkers by profession. You compare features. You evaluate ROI. You read case studies. You analyse competitors. So when you build a landing page, you build it for someone who thinks the way you do: carefully, logically, with full attention.

But most buying decisions run on System 1. Your customer isn't weighing pros and cons. They're scanning for signals that this business is trustworthy, relevant, and "good enough."

Byron Sharp's research at the Ehrenberg-Bass Institute confirms this across multiple countries and categories. Most consumers don't perceive meaningful differences between competing brands. 77% of Apple users don't see the brand as uniquely different from competitors. They chose it because it was mentally available, not because they sat down and compared specifications.

Sharp describes buyers as "cognitive misers": people who spend just enough mental effort to make a decision that's good enough, then move on. They satisfice rather than optimise.

The evidence from decades of eye-tracking research shows what this looks like in practice:

The Perception Canyon

If the false consensus effect were a small, correctable bias, it might not matter much. But the gap between what businesses believe and what customers experience is staggering.

It gets worse. According to Qualtrics customer experience data, 66% of brands believe their customer experience is improving. Only 17% of consumers agree. That's not a gap. It's a canyon.

Where does this canyon come from? The same place: projection. Businesses evaluate their own marketing through the eyes of someone who already knows the brand, already understands the offer, and already cares about the details. The customer is coming in cold.

Rory Sutherland captures why this matters. He argues that decisions rarely follow strict logic. Instead, they obey "psycho-logic": internal psychological rules that prioritise feelings, context, and intuition over rational calculation. The most persistently overlooked variable in business isn't data or strategy. It's the psychological reality that sits beneath every buying decision and is almost entirely absent from how businesses build their marketing.

Your landing page might explain your service beautifully. Your ad copy might cover every benefit. Your email sequence might build a logical case over seven touchpoints. But if the customer's actual decision process runs on gut feel, familiarity, and mental shortcuts, then your carefully constructed argument is playing to an empty room. This is also why the way you describe your product often matters more than the product itself.

What This Actually Looks Like in Your Business

Theory is one thing. Here's how the projection bias shows up in the marketing of a typical Australian SME:

This is also why clicks that don't convert to leads are rarely a traffic problem. They're a gap between what your marketing communicates to you (who already understands) and what it communicates to a stranger (who doesn't).

The Uncomfortable Fix

Sutherland argues that "it doesn't pay to be logical if everyone else is being logical." Applied here: it doesn't pay to build marketing the way every other business does, which is to say, for themselves.

The fix is uncomfortable because it requires admitting that your intuition about your own customers is, statistically, wrong about half the time.

What This Means for Your Business

The false consensus effect isn't a theoretical curiosity. It's the reason your landing page converts at 3% instead of 8%. It's the reason your email open rates decline after the second send. It's the reason your Google Ads get clicks but not enquiries.

The gap between how you experience your marketing and how your customers experience it is measurable, significant, and fixable.

Pick one page. Strip it back to what a scanner needs in 54 seconds. Test it against your current version. The results will tell you how far your internal perspective has drifted from your customer's reality.

The next time you're reviewing your marketing and thinking "this makes sense to me," remember: the research says that's exactly the problem.
