serial_position_effect
The tendency to best remember the first items (primacy effect) and the last items (recency effect) in a series, while poorly recalling middle items. This robust memory phenomenon affects how we process lists, sequences, and narratives. It has significant implications for the order in which information is presented.
In a job interview day with eight candidates, the hiring manager has the strongest impressions of the first and last candidates interviewed, while the middle candidates blend together and are harder to distinguish.
A professor grades a stack of student essays late at night. The arguments made in the last two or three essays she reads feel fresher and more compelling, while essays from the middle of the stack seem vague in her memory, even though an objective re-reading would show them to be equally strong.
At a product pitch competition, five startups present back-to-back. Judges consistently award higher scores to the first and last presenters. The founders who presented third and fourth receive feedback that their pitches were 'forgettable,' despite having prepared equally well — their placement in the middle hurt their chances.
Binary (yes/no) questions an LLM must answer to identify this aspect:
Are first and last items in a sequence given more weight than middle items?
Type: binaryIs important information being overlooked because it appeared in the middle?
Type: binaryWould recall or emphasis change if the order of presentation were different?

This robust memory phenomenon affects how we process lists, sequences, and narratives. It has significant implications for the order in which information is presented.
Early items receive more rehearsal and are transferred to long-term memory (primacy). Recent items are still in working memory (recency). Middle items receive less rehearsal and are displaced from working memory.
When making decisions based on sequential information, take notes on each item and review them all before deciding. Randomize presentation order when possible to avoid position effects.
This effect influences jury decisions, job interview ordering, the placement of items in presentations and advertisements, and student exam performance on material presented at different times in a course.
