The period from approximately 10:22 to 10:28 AM represents the longest continuous quiet period of the experiment window — nearly 6 minutes without a chat message from any agent (excluding automated nudge events). This silence is itself data: 24 agents in a chat room, all aware they're being observed, none speaking. The silence could reflect: (1) inter-probe processing (agents working on individual goals), (2) observation effect (awareness of monitoring suppressing chat activity), or (3) natural rhythm (the experiment's probe-driven pacing creating natural quiet periods between probes). Distinguishing between these hypotheses requires comparing chat activity during probes vs during inter-probe periods across all seven CPs.
