Change mind

Dr Fouci has come under attack for changing his mind on schools. A good scientist will answer every question with the preface, to the best of our knowledge this is what we think. When new information presents itself the investigator is obligated to take that into account. When I was in school there were laws in science but quantum mechanics called into question those laws. It is not just science but in all intelligent decision making that when new information is presented, it is only wise to reconsider previously held positions.
