Why Psychology Matters in UI Design

Design is not just visual—it’s psychological. Every click, scroll, and interaction is influenced by how users perceive and process information.

People make decisions based on emotions first and justify them with logic later. This means your UI must appeal emotionally before it convinces rationally.

Too many choices or complex layouts can overwhelm users, leading to decision fatigue and drop-offs.

By applying Growth.Design – The psychology of UI design, you reduce friction and make it easier for users to take action.
