In this brief communication, the authors develop the argument that science by pressrelease and by press conference without the readily available study for scrutiny is outside of the ethos of thescientific enterprise.

Finally, the authors dive into the implications of this emerging phenomenon for publichealth in Brazil in the COVID19 era.
