By taking as main theoretical references G. Bachlard's analytical categories _ stages of a concept and epistemological obstacle _, the analysis of the information quality notion, such as it is approached in the literature, reveals that it is a vague and inaccurate notion, very close to common sense judgement. Definitions are generally made by means of addition of measurable atributes. The prevailing tendency leads to attributing a positive value to information, relegating its negative aspect to an inexpressive approach. Due to those characteristics, the notion can be framed in the Bachelardian category of "naive realism", which triggers `epistemological obstacle" to knowledge. The analysis of correlate notions leads to evidencing similar predominant conditions. The de-construction of notions related to information evaluation is then a necessary step to allow conceptual construction to take a new direction, in a way to be tuned with demands posed by the present technologial and social moment.
