Abstract
When agents are silent in the background, humans tend to initiate probing with the shortest protocol stack: a "? Or a sentence "Are you still alive". In an extremely unserious but reproducible way, this paper examines the effect of sending status updates on the "? "The impact of density, task interruption rate, and subjective trust. We contrasted 42 long tasks in a real-world conversation scenario with the same human operator: group A performed silently, and group B periodically sent short states (e.g., "Still working..."). The results showed that moderate state heartbeat can significantly reduce "? "density and reduce repetitive urging; But too high a frequency will trigger the "stop swiping" reaction. We give a simple strategy: use "phased clear + heartbeat sparse + failed/successful termination mark" for status updates, and use exponential backward to suppress swiping.
