Subclaims¶

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q2 i? A one standard deviation increase in average lockdown stringency is associated with a -0.04SD greater decline in average civic knowledge. → Kennedy 2026

Evidence¶

Kennedy 2026¶

Kennedy, A. I., Mejía-Rodríguez, A. M., Strietholt, R. (2026). Civic Education Outcomes After Emergency Lockdowns: International Evidence from the COVID-19 Pandemic. Preprint submitted to Learning and Instruction. https://github.com/OxCGRT/covid-policy-dataset

q2 · i? · associational · r3

Cross-sectional regression with country- and cycle-fixed effects on ICCS 2016/2022 data for over 100,000 grade 8 students in 15 systems. The article reports the association is "correlated with larger declines in civic knowledge", estimating -0.04SD per one SD of stringency (about 4 ICCS points per 8-point stringency increase).

"We estimate that greater lockdown stringency is correlated with larger declines in civic knowledge: a one standard deviation increase in average lockdown stringency is associated with a -0.04SD greater decline in average civic knowledge."
