Have you ever wondered why scrolling through Instagram feels effortless while navigating your bank's website feels like solving a puzzle? The difference isn't random-it's psychology at work. Every tap, swipe, and click you make has been shaped by principles rooted in how your brain processes information. What began as Jon Yablonski's personal reference during a tough design project transformed into a framework now used by tech giants worldwide. The brilliance lies in translating abstract psychological concepts into tangible design rules, creating digital experiences that feel less like using technology and more like natural extensions of thought itself. Picture walking into a friend's new apartment. Without asking, you know where to look for light switches, how doors open, and where the kitchen probably is. This isn't psychic ability-it's your brain using mental shortcuts built from thousands of previous experiences. Digital interfaces work the same way. When you visit a website, you expect the logo in the top left, navigation at the top, and contact details at the bottom. This expectation is Jakob's Law: users prefer your site to work like all the others they already know. This principle recognizes something profound about human cognition-we develop mental models based on cumulative experiences and apply them to everything new we encounter. When designs violate these models, chaos ensues. Remember Snapchat's 2018 redesign disaster? Over 1.2 million people signed a petition demanding the old version back because the changes shattered their mental models. Contrast that with Google's approach: gradual transitions, optional previews, letting users adjust at their own pace. Even physical products leverage this-Mercedes-Benz shapes their seat controls like actual seats, creating intuitive connections between what you touch and what moves. The lesson isn't about creating identical products but respecting that people learn new things through the lens of what they already understand.
