Social proof: use and backfires

Welcome to another episode of Build a Better Agency! This week, host Drew McLellan sits down with agency owner and behavioral science expert Nancy Harhut to unlock the hidden forces behind human decision-making—and how they impact your agency's marketing success. Drawing on her years of experience and her deep dive into the psychology of persuasion, Nancy brings a fresh perspective on why people do what they do—and how marketers can ethically harness those instincts to drive action.

In this episode, Nancy breaks down the fundamentals of behavioral science, emphasizing the powerful shortcuts our brains take when making decisions. Together, Drew and Nancy explore concepts like autonomy bias, social proof, and left-digit pricing, providing practical strategies for agencies to leverage these psychological triggers in everything from copywriting to pricing models. Whether it's using testimonials the right way, framing choices to nudge conversions, or tapping into the subtle cues that build trust, Nancy's real-world examples and research-backed tips are sure to spark new ideas.

They also tackle the big question of technology's role in the age of AI—exploring how artificial intelligence can support (but not replace) the human art of persuasion. Plus, they discuss how behavioral science applies across both B2B and B2C spaces, and offer actionable advice for getting clients on board with a more psychologically informed approach to marketing.

If you're ready to move beyond generic messaging and start connecting with your audience on a deeper, more instinctive level, this episode is a must-listen. By the end, you'll have a toolkit of proven tactics you can apply to your agency's work immediately—boosting engagement, persuasion, and results for both you and your clients.
