The Study of Social Differences and Inequalities Lab, created in 2001, has a transdisciplinary character, proposing to analyse the historically produced diacritic traits that shape difference and inequality. Especially, those related to status, for instance, position in the labour market, gender, generation, ethnic and racial status, and also, linguistic, regional and national status, among others, that not only distinguish, but hierarchize, subordinate, oppose and exclude people and groups, directing and producing behaviour. It is understood that taxonomies aren’t neutral and are experienced within a correlation of knowledge and power in the construction of their subjectivities. status, de ocupação no mercado de trabalho, de gênero, de geração, as étnicas e as raciais, assim como as linguísticas, as regionais e nacionais, entre outras, que não apenas distinguem, mas hierarquizam, subordinam, opõem e excluem pessoas e grupos, direcionando e produzindo condutas. Entende que as taxonomias não são neutras, encontrando-se na relação saber-poder em suas construções de subjetividades.

LEDDES is, therefore, ethically focused on the questioning of social difference and inequality affirming the importance of treating people equally in all institutional spheres and situations that affect their opportunities. With this in mind, we propose a historiographic exercise which is always interacting with the diversified agenda of movements and groups that make up society, establishing a dialogue with other spaces of knowledge, whether academic or not. This concern guides our research and outreach practice through a plural perspective without losing the power of analysis and our commitment as professionals of historical knowledge.
