The purpose of this article is to reflect mainly based on Vygotsky and Moscovici, on the development of theories about the relationship between the studies in cognitive and social approaches that happened in the sixties Europe, to understand the historical mo-ment in which it began its social approach by the In-formation Science (CI) as she institutionalized with a strong tendency to US influence in its epistemo-logical composition. Raises reflections that depart from social representations coming from the Socio-logy and Social Psychology seek to realize influen-ces and / or equivalence in relation to the emergence of social approach to CI. It also briefly the Latour's view of the idea of purification and modern science in order to understand how CI falls within that theo-retical framework. As a result, it was noticed and it was discussed on delaying the onset or the adoption of a social nature in theoretical and methodological field of IC, not a science-modern, open to interdisci-plinary solutions (strongly linked to Sociology) for some of their research problems and a member of a network of horizontal socio-technical relations.
