Serial Position Effect

The Serial Position Effect is a cognitive bias that suggests people are more likely to remember the first and last items in a series, with middle items often being forgotten. In UX design, this principle can influence how information is structured, such as prioritizing key content at the beginning and end of a page or navigation sequence to improve recall and attention.

The serial position effect is actionable guidance for navigation and pricing design: your most important items should appear first or last, not in the middle. In pricing page design, this means putting your recommended plan at the beginning or end of your tier list, not buried in the middle where it's least memorable. In navigation, your primary CTA and most-used features belong in the first or last positions in any list or menu.

Restaurant menus are designed using serial position effect — the most profitable items are placed at the top and bottom of sections, while lower-margin items are placed in the middle where they'll be least remembered. Digital menu boards use the same principle, placing promoted items in the first and last positions of any category list.
