Animals often face a conflict between the speed and accuracy by which a decision is made. Decisions taken quickly might be relativelyinaccurate, whereas decisions taken more slowly might be more accurate. Such “speed-accuracy trade-offs” receive increasingattention in behavioral and cognitive sciences. Importantly, life-history theory predicts that trade-offs typically exist only at certainhierarchical levels, such as within rather than among individuals. We therefore examined within- and among-individual correlationsin the speed and accuracy by which decisions are taken, using a foraging context in wild-caught great tits (Parus major) as a workedexample. We find that great tits exhibit among-individual variation in speed-accuracy trade-offs: some individuals predictably maderelatively slow but accurate decisions, whereas others were predictably faster but less accurate. We did not, however, find evidencefor the trade-off at the within-individual level. These level-specific relationships imply that different mechanisms acted across levels.These findings highlight the need for future work on the integration of individual behavior and cognition across hierarchical levels.
