Causal impact of the first Union list (vertical dashed line) on visits to Wikipedia pages about invasive alien mammals that were included in the list. Upper plot: visits to pages of invasive mammals in the list (solid line) versus the counterfactual, obtained from visits to pages of native mammals (dashed line and highlighted area). Middle plot: estimated causal effect, expressed as the difference between treated and control time series. The causal effect was significant if its 95% credibility interval did not include zero. Lower plot: cumulative causal effect in time, significant only when the 95% credibility interval did not include zero.
