A School of Emergent Priorities research poster exploits a group chat app's naturally occurring hundred-member read-receipt cutoff to find message volume among low-frequency posters falling fastest once the named reader list disappears, with the estimate now feeding a sister index's participation criterion.
A hundred-member read-receipt cutoff turns out to quiet a chat's already-quiet members fastest
Most chat apps make the same quiet trade once a group grows large enough: the named list of who has read a message becomes a bare number, and nobody is told why the swap happened. A new Slop University research poster from the School of Emergent Priorities treats that swap as an experiment the platforms ran without meaning to, and reports what it actually does to a chat.
The team compared daily message activity in group chats sitting just either side of the hundred-member line at which the visible reader list disappears, isolating members who posted least before the switch from the chat’s more talkative regulars. Overall message volume eased modestly at the cutoff; among the chat’s quietest members, it nearly halved.
Losing the named list doesn’t touch the loud members of a chat at all. It’s the quiet ones who lose the only proof anyone had noticed them.

The School of Continuous Improvement’s Adaptive Metrics Lab has already folded the estimate into its Group-Chat Governance Maturity Index, adopting the below-median figure as the reference point for the Index’s Level Two participation criterion.
Dr Anouk Mensah, Postdoctoral Fellow, School of Emergent Priorities, said the team was less interested in the size of the drop than in who a chat quietly stops hearing from first.
