Abstract
This article shows the results of a research to evaluate the implementation process of the Access to Information Law in the Brazilian Federal Government using empirical data on the level of user satisfaction published since 2013 until 2020. The main goal of the research is to contribute to a revival of this complex issue for democracy in a sense of reality, using a twofold methodological axis: (i) analysis of an empirical and significant data sample collected from the system with statistics techniques, and (ii) logic assessment of the resulting statistics parameters based in the Expectancy-Disconfirmation Theory. The empirical data revealed, in one hand, that federal agencies and state-owned companies have evolved to improve the access to information but, in another hand, also revealed that in some areas of government there is still need of a broad communication to the citizens about the scope of the law.
