Eight Psychology Experiments for Marketers

What happens when you combine practical digital marketing experience with behavioural science? In this episode, Daniel Rowles is joined by Phil Agnew, host of the Nudge podcast and a specialist in behavioural science, to explore eight psychology experiments and principles that can help marketers create more effective campaigns, stronger customer experiences and more persuasive messaging. Phil shares the original studies behind concepts such as social proof, loss aversion, anchoring and the peak-end rule, then shows how they can be applied in real marketing scenarios, from Reddit ads and SaaS websites to loyalty programmes, pricing pages and customer journeys. The result is a highly practical episode for marketers who want to sharpen their thinking and make better decisions in a world full of noise, automation and increasingly generic content. In This Episode Social proof: why it still works, why specificity matters, and why implying popularity can be more powerful than simply claiming it Loyalty and endowed progress: how giving customers a sense of momentum can make them more likely to complete a journey and stay engaged Loss aversion: why messages framed around what people stand to lose can outperform those focused only on gains The pratfall effect: how showing a flaw, when paired with clear competence, can make a brand or person more likeable Distinctiveness: why standing out matters even more in an AI-saturated content landscape Anchoring: how the first number, comparison or frame people see can radically shape how they judge value The peak-end rule: why customers often remember the emotional high point and the ending of an experience more than everything in between Visible effort: why people value products, services and content more when they can see the work behind them Real examples from digital marketing: including Reddit ad testing, website messaging, social proof banners, pricing psychology and travel search UX Key Takeaways Behavioural science is most useful when it is translated into practical tests, not treated as abstract theory Social proof works best when it feels natural and contextual, rather than overly promotional Small shifts in wording can have a major effect on click-throughs, conversions and retention Customers do not always judge experiences rationally. They remember moments, contrasts and endings Showing some humanity or imperfection can make brands feel more credible and relatable Distinctive positioning is becoming more valuable as AI makes average content easier to produce at scale Helping customers feel progress, momentum or visibility into effort can improve engagement and loyalty Marketers should revisit core psychological principles before chasing every new platform or tool 📥 Access the show notes, tools, and links at:
