- Lucas: Luna, I want to start with a bet. I'm going to show you two sequences of Chinese characters — you don't read Chinese, right? Luna: Not a single character. I'd be guessing. Lucas: Good. So I flash one sequence five times, and another sequence just once. Then I ask you which one you like better. Which do you pick? Luna: I'm guessing the one I've seen more. Even though I have no idea what either means. Lucas: Exactly right. And that's the mere-exposure effect — probably the most boringly powerful bias in consumer behavior. The more you've seen something, the more you tend to like it, even if you never consciously paid attention. Luna: But this feels almost too simple. Like, of course I prefer the familiar. Isn't that just habit? Lucas: It's deeper than habit. The classic experiment was done in 1968 by Robert Zajonc at the University of Michigan. He showed people nonsense words, Chinese characters, even random polygons — things with no prior meaning. And the more times a stimulus appeared, the higher the participants rated it on a likeability scale. The effect held even when exposures were subliminal — one millisecond flashes, too fast for conscious recognition. Luna: Subliminal? So my brain is keeping score even when I'm not aware of seeing anything? Lucas: Exactly. Your brain has a kind of fluency detector. Familiar stimuli are easier to process — the neural pathways fire more smoothly — and that ease gets misattributed as liking. It's an efficiency hack that evolution built into us: if you've survived an encounter before, it's probably safe. But in the supermarket, it means you reach for the brand you've seen 10,000 times. Luna: And companies know this. Coca-Cola's red can, the shape of a Tide bottle — they're designed to be unmistakable, even from the corner of your eye. Lucas: Right. And it's not just visual. Think about jingles, sound logos like the Intel chime, even the font on a Starbucks cup. Every repeated exposure builds a tiny preference increment. Over decades, that compounds into a massive moat. A 2019 study in the Journal of Marketing found that established brands can charge a 'familiarity premium' of roughly 15 to 20 percent over generics, even when the products are chemically identical. Luna: So generic ibuprofen and Advil are the same drug, but Advil gets a 20 percent markup because we've seen the name since childhood. Lucas: Exactly. And the effect is strongest in low-stakes decisions — grabbing a soda, picking a snack, choosing a streaming movie. When we don't care deeply, we default to the familiar. It saves mental energy. Luna: But what about high-stakes decisions? Like choosing a software platform for your business? Does mere exposure still work? Lucas: That's a great question, and it gets into the boundary conditions. For complex products, mere exposure isn't enough — you also need the illusion of truth. If you've seen an ad for a CRM tool 50 times, you start to believe its claims are more credible, even if you've never evaluated it. A 2018 study in the Journal of Consumer Research showed that repeated exposure to a brand name increased trust ratings about 30 percent, independent of any actual information. Luna: So the incumbency advantage is huge. A new brand not only has to be better, it has to overcome the 'I've never heard of you' skepticism. Lucas: And that's why venture-backed startups burn cash on ads before they have a product. They're buying exposures to build the familiarity buffer. The first 10 million impressions aren't about conversion — they're about creating the feeling that 'this company is everywhere, so it must be legitimate.' Luna: I've heard that called the 'familiarity tax' on new entrants. It's the extra cost of being unknown. Lucas: Exactly. And there's a fascinating twist: the mere-exposure effect can backfire if the initial exposure is negative. Zajonc found that if you flash a stimulus too many times — say, more than 20 iterations — the preference plateaus and can even decline. Overexposure breeds boredom. That's why brands do refreshes, like Coca-Cola's 'Share a Coke' campaign with names on bottles. It reintroduces novelty while keeping the core shape. Luna: So there's a sweet spot. Enough to be familiar, not so much that you're annoying. Lucas: Right. And the digital world makes this even more powerful. Think about your Netflix homepage. The thumbnails you've already hovered over, the shows you've partially watched — they get priority placement. Netflix's algorithm literally exploits mere exposure by showing you what you've already glanced at. It's not just personalization; it's a preference-creation engine. Luna: And that's why I end up watching the same true-crime docuseries I've seen clips of before, instead of that award-winning foreign film I've never heard of. Lucas: Exactly. The foreign film has zero prior exposures in your brain. It's competing against maybe 50 exposures for that true-crime show. The playing field isn't level. Luna: Okay, so if I know about this bias, can I overcome it? Or am I stuck reaching for the same brands forever? Lucas: You can overcome it, but it takes deliberate effort. One strategy is to force yourself to choose the unfamiliar option in a low-risk category — say, buy the off-brand cereal once. Usually, you'll find it's fine, and future exposures to that brand will start building a new familiarity loop. Another trick is to delay your decision. When you pause for 10 seconds, the automatic fluency-based preference weakens, and you can engage more analytic thinking. Luna: So the bias is strongest when we're in a hurry. That's why checkout lanes are full of familiar candy bars. Lucas: Exactly. And why Amazon's one-click ordering is so effective. It removes the pause where you might second-guess. Luna: Speaking of second-guessing, I want to bring up the endowment effect — the fact that we value things more once we own them. Is mere exposure a prerequisite for that? I mean, if I've never seen a product, can I really feel attached to it? Lucas: That's a sharp connection. I'd argue that mere exposure is a necessary condition for the endowment effect. You can't feel ownership attachment to something you haven't had time to become familiar with. In fact, one study found that ownership feelings increased after just 30 seconds of tactile contact — like holding a mug. But that 30 seconds is essentially a burst of exposure. So yes, familiarity is the foundation on which loss aversion builds. Luna: So the whole edifice of consumer bias — anchoring, loss aversion, mental accounting — it all rests on this bedrock of 'I've seen it before, therefore I like it.' Lucas: I think that's defensible. It's the most primitive cognitive shortcut. And it's worth reflecting on that, because if you're aware of it, you can start questioning your own preferences. Like, do I actually like this brand, or have I just seen it a hundred times? Luna: That's a question worth asking before every purchase. And honestly, that's the kind of insight we try to bring every week on this show — the tools to think a little more clearly about your own money. And we do it without ads, because we think that helps keep the perspective honest. Lucas: Absolutely. We deliberately keep this show ad-free. So if you've been getting value from these episodes — whether it's mere exposure or mental accounting — and you want to support that independence, there's a simple way. It's buy me a coffee dot com slash fexingo. That's buy me a coffee dot com slash fexingo. No pressure, just an option to keep this free for everyone. Luna: And it honestly makes a difference. Even one coffee helps cover hosting and research time. So thank you to anyone who's already done that. Lucas: Alright, back to the brain. So where do we go from here? The mere-exposure effect has an interesting implication for product launches. If you're introducing something truly novel — like a new category of food — you might need to give away samples for free just to get that first exposure. Because the first taste is the hardest hurdle. Luna: Costco does this brilliantly with their sample stations. You try a tiny sausage, you feel a flicker of familiarity, and suddenly the bulk pack seems appealing. Lucas: Exactly. That first exposure is an investment in future preference. And the effect can last for years. A 2020 study found that consumers who tried a new snack in a store were 40 percent more likely to buy it again six months later, even if they didn't remember trying it. Luna: They didn't even remember? So it's pure subconscious influence. Lucas: Completely subconscious. That's the eerie part. Your brain keeps a tally you can't access. And that's why the most successful brands are the ones that get into your peripheral vision early and stay there. It's not about convincing you; it's about being there. Luna: So next time I'm in the grocery aisle, I'll try to ask myself: am I reaching for this because I've seen it 500 times, or because I actually want it? Lucas: And if you can answer honestly, you've already beaten the bias. For today, that's a good note to end on. Thanks for listening.
