TL;DR

Event studies — the financial-sector method for attributing stock-price fluctuations to announcements — can rigorously attribute social-media sentiment changes to policy-level COVID-19 non-pharmaceutical interventions (NPIs), bringing proper event attribution and significance testing to a literature that lacked both. A case study of Twitter sentiment towards policy-level NPIs in Canada confirms a generally positive connection between NPI announcements and sentiment, with a promising correlation to a public-health survey of popular compliance.
