With more than half a million deaths due to the Sars-Cov-2 virus in Brazil between March 2020 and June 2021, the Federal Government has been held responsible by society and other strata of power for mismanaging the pandemic of Covid-19. This led the Federal Senate to open a Investigating Comission (CPI) of Covid, in 2021, to investigate the actions and omissions of the Government in this pandemic period. It is within this universe that we aim, in this work, to explain how the Dunning-Kruger Effect (DUNNING, 2011) and cognitive dissonance (FESTINGER, 1968) are manifested in the CPI, institutionalizing disinformation (WARDLE; DERAKHSHAN, 2017) in Brazil. For this purpose, we selected excerpts from the testimonies of three prominent figures in the government summoned to testify in the process: oncologist Nise Yamaguchi, pediatrician Mayra Pinheiro and General Eduardo Pazuello and we show how these concepts materialize in their speeches. Preliminary results indicate that the disinformation board is legitimized at an institutional level, mainly by the beliefs and values that can be demonstrated by the dunning-kruger effect and by the cognitive dissonance acting on decision-makers in the Federal Government.
