The simplest solution is often the best. If there are several equivalent solutions available, the simplest or least complex solution should always be preferred. Similar to the KISS principle.
Occam's razor states that when there are several possible explanations for a phenomenon, the simplest explanation should usually be preferred, as long as it sufficiently covers all observable facts. A more complicated approach is therefore only justified if the simpler hypothesis cannot explain important aspects.

Application in UX and UI design
In UX and UI design, Occam's razor can help to reduce information architectures, workflows and visual elements to the essentials. When considering several solutions to a particular design problem, the simplest and clearest variant is often the most successful because it avoids unnecessary complexity and does not overwhelm users.
Interface designs that focus on visually supporting the necessary functions and omit unnecessary details usually lead to a more intuitive and user-friendly User Experience.
