What this does not establish
Do not infer metered emissions, universal moral-persuasion effects or long-term persistence.
Counterevidence & uncertainty
Behavior was self-reported, sample N was small, messages were not randomly shuffled by day, and subgroup backlash qualifies the average direction.
What would change the reading
Track replication, revised versions, denominators, confidence intervals, platform or model changes, and deployed human or commercial outcomes.
