Panel time series for \(p_i^{\text {Death}}(t)\) (blue), the logarithm of the daily deaths (orange), and the logarithm of the daily cases (green). Each panel presents a different country, with the country name provided in the subplot title. The correlation between \(p_i^{\text {Death}}(t)\) and the national daily death rate is given in parentheses for each country. Data is smoothed with a 3-day moving average and standardized with their z-score to make them visually comparable. Black vertical lines represent peaks in the death discourse caused by exogenous events not related to psychophysical numbing (see “Appendix 2” for details) which we remove from the time series
