- Lucas: So there's this experiment from the 1960s. Psychologist Robert Zajonc showed people a series of Chinese characters — completely unfamiliar symbols — and varied how many times each one appeared. Some he showed once, some five times, some up to twenty-five times. Luna: And the participants had no idea what the characters meant, right? They were just meaningless shapes. Lucas: Exactly. Later, he asked them to rate how positive or negative the characters felt. The ones they'd seen more frequently were rated more favourably — even though they had no conscious memory of having seen them before. That's the Mere Exposure Effect in its purest form. Luna: So the brain builds a preference for something just because it's familiar, even if we're not aware we've encountered it. That's wild. Lucas: And it's been replicated dozens of times — with nonsense words, faces, geometric shapes, even musical snippets. The effect is robust. And it has huge implications for marketing, because it suggests that brand preference can be built through sheer repetition, independent of any rational evaluation. Luna: But isn't that just advertising 101? Show the ad enough times and people buy? Lucas: It's deeper than that. The Mere Exposure Effect works even when the exposure is subliminal — flashed so quickly you can't consciously register it. And it works even when the person initially dislikes the stimulus. In one study, participants were exposed to a piece of music they initially hated; after repeated hearings, their liking increased. Luna: So you can literally wear down resistance through repeated exposure. Lucas: That's the mechanism. But there's a critical nuance: the effect is curvilinear. Up to a point, more exposure increases liking. After that, overexposure breeds boredom or annoyance. So marketers need to find the sweet spot — enough repetition to build familiarity, not so much that it becomes grating. Luna: Can you think of a brand that nailed that balance? Or one that overdid it? Lucas: Coca-Cola is a classic example of sustained, moderate exposure. Their logo and red color are everywhere, but they vary the creative execution — seasonal ads, limited editions, cultural tie-ins — so the repetition doesn't feel stale. They've been doing it for over a century. On the other hand, think of those direct to consumer mattress companies that saturated podcasts and YouTube for a couple of years. Eventually, listeners started rolling their eyes. Luna: Yeah, I remember that. There was a point where you couldn't hear a podcast without a mattress ad. And the effect probably flipped from familiarity to annoyance. Lucas: Exactly. The two-factor model explains this: initial exposure reduces uncertainty, which feels good. But after uncertainty is gone, further exposure only increases boredom. So the key is to create enough novelty within the familiar framework. Luna: How does this play into digital platforms where algorithms control exposure? Lucas: It's everywhere. Take Netflix's thumbnail selection — they show you the same title with different artwork depending on your viewing history. The algorithm optimises for the image you're most likely to click, which often means images from movies or shows you've already seen partially. They're banking on the Mere Exposure Effect to make that thumbnail feel more appealing. Luna: And Spotify's Discover Weekly — it mixes familiar artists with new ones. The algorithm knows that if you've heard a song before, even once, you're more likely to like it. So it blends in tracks that are similar but not identical to what you've heard. Lucas: Right. And that's smart because the Mere Exposure Effect is strongest for stimuli you initially had a neutral or slightly positive reaction to. If you've never heard an artist, the first exposure is novel — but it might be too unfamiliar to generate a preference. By embedding new songs in a playlist with familiar ones, Spotify gives the new song a boost. Luna: So how should a small business owner or a startup marketer apply this? They don't have the budget for a Super Bowl ad. Lucas: The good news is, the Mere Exposure Effect doesn't require huge reach. It requires frequency. For a local business, that could mean consistent social media posting — even if only a small audience sees it, repeated exposure to that same audience builds a sense of familiarity and trust. It could mean being present at community events regularly, or running a retargeting ad campaign that shows a banner to the same visitors multiple times. Luna: So it's about showing up consistently, not trying to go viral. Lucas: Exactly. And one more thing: the effect works across sensory modalities. Seeing a brand name repeatedly in your email inbox, hearing it on a podcast, seeing a billboard — all those exposures add up, even if they're in different contexts. So a multi-channel approach can amplify the effect without necessarily increasing ad spend on any single channel. Luna: It's almost like you're building a mental shortcut for the consumer: 'I've seen this before, so it must be okay.' Lucas: That's exactly what's happening. And it's worth noting that the Mere Exposure Effect works even when the initial encounter was negative. There's a study where participants saw a person who initially seemed unlikeable; after repeated brief exposures, their rating improved. So even if your first impression isn't great, consistency can eventually turn it around. Luna: But there's a limit, as you said. How do you know when you've hit that sweet spot? Lucas: That's the million-dollar question. There's no universal number — it depends on the stimulus, the audience, the context. But a rule of thumb from advertising research is that three to five exposures in a short period can build awareness, but beyond seven to ten within a week, you risk diminishing returns. The key is to monitor engagement metrics and brand sentiment over time. Luna: And if you see people actively ignoring or complaining about your ads, you've probably passed the peak. Lucas: Exactly. Now, there's one more nuance I want to mention: the Mere Exposure Effect is strongest when the exposures are spaced out over time, rather than massed all at once. That's why media planners talk about 'frequency capping' — limiting how many times a person sees an ad per day. Spaced repetition builds familiarity more effectively than a single binge. Luna: So don't blast your audience with the same ad in a single day. Spread it out over a week. Lucas: Right. And this ties back to the idea that the brain's initial response to a stimulus is uncertainty. Repeated but spaced exposure reduces that uncertainty gradually, like getting to know a new colleague over several coffee breaks rather than a single eight-hour meeting. Luna: That's a great analogy. I'm thinking about how this applies to personal branding, too. If you want people to trust your expertise, you need to show up consistently — post regularly, comment on threads, be visible. It's the same principle. Lucas: Absolutely. The Mere Exposure Effect doesn't care if it's a product or a person. It's a fundamental feature of how our brains process stimuli. And it's one of the most reliable effects in psychology. Which is why it's worth understanding if you're trying to build any kind of brand. Luna: So if I'm launching a new product, I should focus less on making one perfect ad and more on a sustained campaign that puts it in front of the same people multiple times? Lucas: That is exactly the takeaway. The first time they see it, they're neutral or skeptical. The third time, it starts to feel familiar. The fifth time, they might actually consider buying. That's the Mere Exposure Effect in action. Luna: And this is why so many marketing psychology podcasts and books exist — because understanding how your brain works can make you a better marketer. Lucas: Speaking of which, if this conversation sparked something you've actually used in your own work, you're exactly the kind of listener who keeps this show going. Marketing Psychology with Fexingo stays ad-free because of listener support — buy me a coffee dot com slash fexingo. It's a simple way to say 'this was worth my time'. Luna: Yeah, and it really does make a difference. Even a small contribution helps us keep digging into these topics without running ads. Lucas: So back to the Mere Exposure Effect — one more practical example. Think about how brands use jingles. The repetition of a short melody, even if you don't like it at first, can become lodged in your brain. And over time, that melody becomes associated with the brand, triggering a feeling of familiarity whenever you hear it. Luna: Like the 'Nationwide is on your side' jingle. I haven't heard it in years, but I still remember it. Lucas: Exactly. That's the Mere Exposure Effect compounding over decades. And it's one reason why audio branding is so powerful — because we can't easily block out sounds the way we can ignore visual ads. Luna: So if you're a startup, maybe a podcast ad read that runs for several months on a niche show could be more effective than a single splashy billboard. Lucas: Potentially, yes. Especially if the podcast audience is consistent and the host's voice becomes familiar. The listener hears the host every week, and then they hear your brand mentioned in that familiar voice — the effect is amplified. Luna: I love that this effect is so simple yet so powerful. It's not about tricking people; it's about tapping into how our brains naturally work. Lucas: And that's what makes it ethical — as long as you're not manipulating people into buying something harmful, you're just making it easier for them to recognise and trust you. Which is a legitimate business goal. Luna: Alright, I think we've covered the core of the Mere Exposure Effect. Let's leave listeners with one actionable tip. Lucas: Sure: next time you're planning a marketing campaign, ask yourself: 'Am I prioritising frequency over flash?' If the answer is no, consider shifting your budget toward repeated, spaced exposures across a few channels rather than a one-off spectacle. Your audience's subconscious will thank you. Luna: And they'll probably end up liking your brand more — without knowing why. Lucas: Exactly. That's the beauty of the Mere Exposure Effect.
