Some groups take days to process information from a Google search before they are ready to discuss it on Reddit, meaning timing is a property of the community's collective brain, not the time of day.

We test whether the delay between information seeking (Google Search) and social engagement (Reddit) is random noise or a structural manifestation of collective cognitive processing. The goal is to explain why identical timing strategies succeed in some domains yet fail in others, and to replace one‑size‑fits‑all calendars with community‑specif
