text: Allcott et al. (2020) found detectable effects on political polarization from just four weeks of Facebook deactivation, demonstrating that polarization-relevant attitude change can manifest in short experimental windows.

text: The framing requires experimental or quasi-experimental evidence with defensible aggregation arguments; rejecting three-month experiments as insufficient would eliminate the primary evidence base for any causal conclusion.
