Applied Psychology: Psychology based UI improvements
summary
Explains concrete UI fixes: apply Gestalt proximity and the law of prognance to remove dividers and group items into cards, use zebra rows for tables, enforce consistent button styles so CTAs read as such, and size/place buttons per Fitts' law for thumb reach. Uses color and bolding to signal thresholds, leverages the von Restorff effect to highlight one item, limits choices to three–four with progressive disclosure, and warns defaults (opt‑in vs default opt-out) drive huge behavior differences.
