# Equivalence of timing and content choice

## Quote: Equivalence of timing and content choice

> "Critically, when we statistically compared effect sizes across the two studies, the differences between timing and content choices were indistinguishable. That is, whether viewers chose the ad itself or the timing of ad display, the benefits were roughly equivalent."

**Why it matters:** This is the load-bearing sentence of the entire source. It is the direct evidence for [[claim-timing-content-equivalence]] and the pivot for the contrarian argument in [[contrarian-timing-vs-content]] — that *when* an ad plays can be swapped for *which* ad plays with no loss of benefit. Note the phrase 'across the two studies,' which is the basis for the study-count nuance flagged in [[claim-timing-content-equivalence]].
