Healthy skepticism is fine, but if I’m skeptical of experts on anything novel, whose information am I supposed to trust? What is a better decision making process? Don’t we have conflicting needs here? We don’t want scientists waiting for perfect information before providing guidance on a constantly evolving situation but then we are unhappy with the guidance they provide?
