# Exercise Cognitive Function Older Adults: When Positive Effects Do Not Generalize ## Signal Exercise had a moderate positive effect on global cognition (d = 0.43; SE = 0,11; p < 0,001) [R1] ## Update Exer-tour and exer-score yielded significant moderate effects on executive function (Stroop A/C; d's = 0.51 and 0.47); there was no significant interaction effect. [R2] ## Synthesis Exercise had a moderate positive effect on global cognition (d = 0.43; SE = 0,11; p < 0,001) In contrast, Exer-tour and exer-score yielded significant moderate effects on executive function (Stroop A/C; d's = 0.51 and 0.47); there was no significant interaction effect. Therefore, for exercise cognitive function older adults, a positive result on the promise endpoint cannot establish differential benefit on the update's null endpoint; decisions should treat the signal as comparator- and outcome-specific rather than a uniform intervention effect. [R1] [R2] ## Limitations The two receipts concern different populations, comparators, and outcomes; without a head-to-head comparison, they cannot establish that one intervention is uniformly superior or harmonize dose, duration, and endpoint aggregation. [R1] [R2] ## Falsifier This boundary would be overturned if receipt-matched evidence in the same populations showed a significant benefit on the update's null comparison or no positive effect on the promise endpoint.
