@johnzajac @sidereal @seachanger @inquiline right. As a clinically trained data scientist who has worked with vaccines, biotechnology, ecologists, public health, interoperability, and health care, even most of my own peers in the US regard me as "eccentric" for still masking indoors. On an intellectual level, some do know better... However, thanks to present day top-down messaging, they perceive the social cost of being cautious as greater than the social benefit of "fitting in".
