  When conducting COVID-19-related research, mathematicians may find themselves
in public service roles. They might engage in policy discussions, collaborate
with politicians and other non-scientists, and use the predictive power of
mathematics to shape substantial decisions. We aim to promote good practice for
ethical mathematical modelling in these difficult times. We begin with some
observations about mathematical modellers, then derive eight questions that all
mathematicians should constantly ask themselves, in order to develop their
mathematics responsibly and ethically.
