Behavioural Psychology Effects That Change How People Buy

Why do some marketing campaigns stick in your mind while others disappear the moment you scroll past? Most marketers spend their time asking what they should say. I think the better question is why do people notice, remember and act in the first place? In this episode, I talk about five behavioural psychology effects that quietly shape buying decisions every day. Not as marketing hacks or manipulation tactics, but as practical ways to understand how real people make choices. We'll look at why familiarity builds trust, why distinctive brands are easier to remember, why the cost of doing nothing is often more motivating than the promise of a better future, why concrete language beats vague marketing every time, and why the most trusted brands aren't afraid to admit when they've stuffed up. Along the way, I'll break down campaigns from Specsavers, Cadbury, WWF, Metro Trains and KFC to show these principles in action. If you've ever wondered why some campaigns become part of culture while others vanish without a trace, this episode will change the way you think about marketing. You'll walk away with a sharper understanding of human behaviour and practical ways to build campaigns that people notice, remember and choose.   Come say hi If you've ever struggled to make your marketing memorable or wondered why your campaigns aren't cutting through, I want to hear about it.
