Recency effect
The most recent items and events loom largest in memory and judgment.
What it means
The recency effect is the finding that information encountered most recently is more accessible and more heavily weighted than information encountered earlier. In list recall it is the second half of the serial position effect, and its mechanism is that the final items are still residing in short-term or working memory at the moment of retrieval, so they are recalled quickly and accurately. This origin is confirmed by the fact that introducing a delay or a distracting task before recall selectively eliminates the recency advantage while leaving early-item (primacy) recall intact. Beyond list memory, recency biases broader judgment: recent events come easily to mind (linking it to the availability heuristic), so people overweight the latest data point when judging trends, performance, or risk. It competes with the primacy effect, and the balance between them depends on timing and on whether a judgment is made immediately or after a delay. It matters because the order and timing of information shape evaluations — the last impression in an interview, the most recent quarter's results, or the closing argument can dominate a decision out of proportion to its true weight.
Examples
Interviewers often remember the last candidate most vividly, giving them an edge unrelated to their actual qualifications.
Reading back a shopping list, you reliably recall the last two items — milk and bread — and lose the middle ones, because the final entries are still sitting in working memory.
A fund that surged last quarter pulls in floods of new money while a decade of mediocre returns barely registers — investors weight the newest number far above the older ones.
