This demonstrates the Serial Position Effect: items at the beginning (primacy) and end (recency) are remembered better than those in the middle.
Formulated by Hermann Ebbinghaus, 19th century
The serial position effect describes how people recall the first items in a sequence (primacy) and the last items (recency) far better than anything in the middle.
It was first documented by psychologist Hermann Ebbinghaus in his 19th-century memory experiments and remains a cornerstone of cognitive psychology.
In interfaces, it is why the most important navigation links go at the start or end of a menu, and why onboarding flows put the single most critical action as the first or last step, not buried in the middle.
