Ever wonder how certain products feel inevitable the moment they appear—rearranging entire markets overnight? In this episode of The Design Psychologist, Thomas sits down with UX pioneer Larry Marine to unpack the mechanics of truly disruptive research—the kind that yields insights so fundamental they can’t be unseen.

Most teams unknowingly skip a handful of critical research steps, blinding themselves to the knowledge that changes everything. Larry shows us how treating users, tasks, and entire processes as flows of knowledge reframes both what you look for and what you ultimately build. Along the way we probe why familiar tools like personas sometimes help—and sometimes hurt—and how principles from cognitive science give sharper edges to every question we ask. 

🔍 You’ll learn 

• What makes research “disruptive.” Why some methods surface game-changing insights while standard approaches miss them.
• The critical steps most teams skip. How a small shift early on can rewrite both your findings and your final design.
• Knowledge-centric mapping. Viewing users and processes through the lens of knowledge—revealing needs that action-based models overlook.
• Where personas really belong. When they clarify design decisions and when they get in the way.
• Cognitive science in practice. Concrete ways to align products with how people actually think and behave.
• A self-audit toolkit. Practical prompts to evaluate (and radically improve) your current research workflow. 

Whether you’re launching a start-up or steering a mature product team, this conversation arms you with a sharper lens and actionable tools to uncover deeper, more market-shaking insights—before someone else does.
