摘要:The COVID-19 crisis is an opportunity for scientists to showcase their skill and the impact that good science can have on society. However, not all scientists have risen to the occasion with the sense of responsibility and accountability that their work deserves. Scientists worldwide have shown, and continue to show, great enthusiasm regarding the use of specific scientific tools, mainly modelling and predictive analytics, to estimate how the virus spreads and behaves and to assess interventions against counterfactual scenarios. In this Commentary, we question whether the application of these tools has always been appropriately managed by discussing the underlying elements of modelling which need to be understood and evaluated for results to be meaningful and credible.
