Based upon the results of three empirical studies conducted in Chile, this paper discusses: (1) the expansion of the perception of a specific type of inequalities in this society: interactive inequalities. These are perceived inequalities that focus on the treatment received in ordinary interactions between individuals and between these and institutions; (2) The fact that these new perceptions must be understood in the context of specific socio- historical transformations of the meanings and scope of the notion of equality. Therefore, this paper pays attention to the paths by which equality has acquired new content in Chilean society – equality in the social bond – making possible and legitimizing the perception of what we have called interactive inequalities. Finally, it argues for the importance and analytical priority of the sociological study of equality, especially when approaching inequalities.
