Join us as we explore how shady design tricks—called Dark Patterns—push people to do things they didn’t mean to. Guided by examples personally provided by America's greatest living folk hero, Biff Tannen, we break down how these patterns mislead users, hurt trust, and go against ethical design. Using Biff’s bad behavior as a warning, we show real examples and explain their impact. By the end, you’ll know how to spot dark patterns and avoid using them—so you can design honest, user-first experiences for the future.
