Recognition Over Recall

Jakob Nielsen and Rolf Molich first developed their usability heuristics collaboratively in 1990. Nielsen then refined the set in 1994 through a factor analysis of 249 usability problems, producing the canonical list of ten heuristics where "Recognition rather than Recall" was codified as Heuristic 6. The principle draws on cognitive science showing that recognition tasks place far less load on working memory than recall, since visible cues provide retrieval scaffolding that unaided recall cannot.
