Pré-publication, Document de travail: In this paper we investigate the implications of assuming that citizens are cognitively constrained for transparency in public life. We model cognitive limitations as reflecting a quantum property of people’s mental representations of the world. There exists a multiplicity of incompatible (Bohr) complementary mental representations of a situation. As a consequence the framing of information plays a crucial role. We show that additional information can be detrimental to a quantum cognitively constrained agent: he may become more confused. We suggest some implications for the design of a public agency’s website.
