Happy Black Friday! Disclaimer: this is not a Black Friday sale. And I’m not trying to sell you anything—except maybe behavioral science in the broader sense. 🤑
But I was recently shopping for an accent chair on Facebook Marketplace, and the experience highlighted the key barriers involved in secondhand shopping:
1. Informational: This chair is nice, but are there others? What do they cost?
2. Logistical: Is this chair worth driving an hour to pick up? Can I get it delivered?
3. Mental model: My understanding of the marketplace is limited. What product categories can I find here? How does it work?
The 3B Framework: Black Friday Edition
How to fix this? How could an e-commerce platform increase sales without offering 90% off Black Friday Bonanza deals?
At Irrational Labs, we use the 3B framework. So in this teardown, I put on my behavioral science hat and ask: how could a savvy PM use the 3B’s (key behavior, barriers, benefits) to boost user engagement and help me get that perfect accent chair? This isn't just about clicks and views; it's about understanding and designing for psychology.
Topics I touch on:
🤖 Increasing trust in AI
🛒 Balancing short-term vs. long-term conversions
🧩 Building a mental model for your product or service
Black Friday may be overhyped but this is one ‘sale’ you don’t want to miss if you want to engage your users more.
See you next time (by then, hopefully I’ll have that accent chair). 🛋️ 👋
