A bigger picture – there is always a difference how we address risks coming directly from Hashem, or indirectly from our enemies:
David rightfully choose a plague v. a war, as there is no end to which evil people might go; We teach Torah in the face of Romans or Soviets, etc. But there is no chiyuv to do bris milah on a bleeding child to prove that we are big tzadikim. This was also addressed in some of teshuvos regarding Covid.
Where the limits of risk are might be a subject for debate. People can indeed be affected by biases here: some because they “believe in science” and will swallow anything to show how “progressive” they are; others – because they do not trust anything “from goyim” and do not know anything themselves. Most are affected by the bias of convenience and personal finance – I don’t want to do some extras; do something my friends do not do; or that can hurt my mossad. (kiso/koso/kaaso).
