Behavioral Science and Habit Design

# Behavioral Science and Habit Design You want people to adopt a new habit, switch to a safer practice, or use your product every day. You've tried education. You've tried incentives. You've tried making the ask "go viral." Nothing stuck. This course teaches you why—and what actually works. Most behavior change fails because we skip the diagnosis. We assume people need motivation when they're drowning in friction. We assume they need willpower when they've never been prompted. We assume they understand the value when they're navigating a confusing interface. This course starts where most interventions fail: **understanding the barrier**. You'll learn the frameworks that work. The Behavioral Model—motivation, ability, trigger—is not a theory; it's a diagnostic tool that points straight to the lever. Habit loops aren't magic; they're how brains automate behavior. Choice architecture isn't manipulation; it's designing the environment so the right choice is effortless. You'll learn when to use each, and why most interventions get it wrong. But knowing the frameworks isn't enough. You'll learn to test, not guess. How to run experiments that separate your intervention's effect from coincidence, regression to the mean, and confounds. How to track whether people actually did the behavior—not whether they said they would. How to read results honestly: a novelty effect looks like success for eight weeks then collapses; you need to see the sustained curve. You'll confront the hard stuff. Unintended consequences—your safety-incentive program makes workers hide errors instead of reporting them. Implementation drift—the intervention works in the pilot site but falls apart when scaled, because the real-world context is messier. The ethics: the difference between a nudge that informs and a manipulation that removes choice. The equity gap: your app-based intervention doesn't reach the people who need it most. This isn't a magic-bullet course. Behavior change is a discipline. You'll leave knowing how to diagnose systematically, design to the barrier, test rigorously, measure fairly, and scale with your eyes open to what can go wrong. You'll learn from real cases: product adoption, health habits, organizational safety, public-service programs. You'll see what worked, what backfired, and why. You'll end with a recognition guide—a map from any behavior-change challenge to the diagnosis methods, design levers, experiments, and ethics that fit. Not a template; a way of thinking. Behavior change is learnable. The science is there. This course teaches the craft.
