A 2020-election field experiment: switching users from algorithmic to chronological feeds changed exposure but not downstream attitudes over three months.
The book’s stance. Bears on adding-channel-can-accelerate-divergence, timescale-distinction, and medium-attached-to-every-gate. Pressure-tests short-run gate-tuning effects; read correctly it supports the timescale distinction, since three-month nulls say nothing about decades. Quote-backed supports/pressureTests edges pending extraction of the source PDF.
