The myth of the rational customer.
Marketers often assume customers weigh up options carefully, comparing features, prices, and benefits before making a choice. In reality, most decisions happen far faster and with less rational thought than we like to believe. Emotions, not logic, are usually what tip the balance.
Daniel Kahneman’s work on behavioural science helps explain why. He describes two systems of thinking. System 1 is fast, automatic, and emotional. System 2 is slower, deliberate, and logical. While we imagine that System 2 runs the show, research shows System 1 influences most everyday decisions, including buying behaviour.
Why emotions work in marketing.
There are three main reasons emotions are so powerful in campaigns:
- Speed: People often make snap decisions without detailed comparison. An emotional pull helps them act quickly.
- Memorability: We remember feelings more vividly than facts. A moving story lingers long after product specs are forgotten.
- Shareability: People are more likely to share content that stirs an emotion – whether it’s joy, pride, or outrage.
This doesn’t mean logic has no role. Features, evidence, and rational arguments help people justify their decision afterwards. But the spark that moves them to buy often comes from emotion.
Common emotional triggers.
Marketers tap into different emotions depending on the audience and context. Some of the most effective include:
- Pride: Celebrating personal achievement or progress.
- Fear of missing out (FOMO): Driving urgency with scarcity or exclusivity.
- Belonging: Showing that a brand reflects identity or community.
- Joy: Associating products with fun, humour, or delight.
- Aspiration: Connecting purchases to personal growth or ambition.
The art is matching the right emotion to the right context.
Examples in action.
John Lewis Christmas adverts have become famous for putting emotion above product features. They rarely show much detail about the items on sale. Instead, they tell heartfelt stories, of friendship, kindness, or nostalgia, that position John Lewis as part of people’s emotional lives during Christmas.
Nike’s “Dream Crazy” campaign leaned into identity and aspiration. Featuring Colin Kaepernick, it wasn’t just about trainers – it was about values, courage, and belonging to a movement. It resonated strongly with Nike’s audience, who saw the brand as aligned with their identity and ambitions.
These examples highlight how emotion connects people to brands in ways logic rarely can.
Balancing emotion and logic.
That said, emotion alone isn’t enough. Customers still want to know a product works, fits their budget, and delivers value. The most effective campaigns strike a balance – using emotion to capture attention and spark action, while providing enough rational support to reassure. A campaign that relies only on sentiment risks being dismissed as gimmickry.
The risks of emotion without substance.
When brands chase emotion without grounding it in real product value, campaigns can backfire. Overly sentimental ads may feel manipulative. Campaigns that use humour or shock without relevance often fail to convert. The lesson is simple: emotion opens the door, but the product experience must live up to the promise.
Takeaway.
People don’t buy based on logic. They buy because something makes them feel proud, safe, inspired, or connected. As a marketer, your role is to understand which emotions matter most to your audience, and then build campaigns that spark them – without neglecting rational needs.
Emotion drives attention, action, and loyalty. Get it right, and you won’t just sell a product, you’ll earn a place in your customer’s story.
