A intera??o que existe entre governo e cidad?os ? determinante para que as pol?ticas p?blicas de um pa?s sejam condizentes com as prefer?ncias da popula??o e n?o de grupos de poder. Sendo assim, torna-se importante analisar a ideia subjacente ? democracia de "governo pela discuss?o" ? luz de teorias que nos iluminem tanto no que diz respeito ? ideia de decis?o coletiva justa, quanto, ao real comportamento humano. Para tal, primeiramente ? apresentada a ideia de raz?o p?blica a contraponto, em particular, as vis?es de Rawls e Sen, dando ?nfase para ao conceito de imparcialidade nas decis?es pol?ticas. Em seguida, na terceira se??o, trabalham-se as ideais de racionalidade, razoabilidade, introduzindo-se os conceitos de heur?sticas, vieses, e valores sociais. Assim, constr?i-se uma associa??o para se pensar sobre os resultados de diferentes tipos de comportamento humano para a democracia e como ? poss?vel refletir a partir dele sobre as ideias de objetividade posicional e transcendental. Finalmente, na se??o IV, realiza-se uma investiga??o emp?rica atrav?s da base de sobre a rela??o entre percep??es sobre informa??es e disposi??es pol?ticas e a frequ?ncia de conversa sobre pol?tica com os amigos. Utiliza-se um modelo de regress?o log?stica ordenada, com dados do Latino Bar?metro de 2015 para o Brasil, aliado ao m?todo de componentes principais para capturar dimens?es explicativas relevantes. Os seguintes resultados obtidos contradizem as hip?teses pr?vias: a falta de confian?a no governo e a percep??o de garantias faltantes n?o significativos, o ativismo dissociado a causas espec?ficas reduz, ao passo que, um senso de cidadania ao reverso aumenta as chances de se conversar sobre pol?tica com mais frequ?ncia com amigos. / The present dissertation aims to investigate the instrumental role of human behaviour for democracy through the idea of public reason. The interaction between government and citizens is decisive for a country's public policies to be in line with population preferences rather than power groups. Thus, it becomes important to analyse the idea underlying democracy of "government by discussion" in the light of theories that enlighten us both with regard to the idea of just collective decision and real human behaviour. To this end, we first counterpoint the idea of public reason, in particular, of Rawls and Sen, with an emphasis on the concept of impartiality in political decisions. Then, in the third section, we work on the notions of rationality, reasonableness, introducing the concepts of heuristics, biases, and social values. Thus, an association is constructed for thinking about the results of different types of human behavior for democracy and how the ideas of positional and transcendental objectivity fit this purpose well. Finally, in section IV, we conduct an empirical investigation based on the relationship between perceptions of relevant political information and dispositions and the frequency of political talk with friends. We use a logistic regression model, with data from the 2015 Latin Barometer for Brazil, combined with principal components method to capture relevant explanatory dimensions. The following results contradict previous hypotheses: lack of trust in the government and the perception of absent guarantees are not significant, while activism dissociated of specific causes reduces and a reverse sense of citizenship increases the chances of talking about politics more frequently with friends.
