A series of links and articles about how anthropology becomes when it decides to enter into action, i.e. coming out of an (impossible) “pure†observation and getting politically involved into the field it studies. In the seventies, in Italy, they used the expression “ricerca-intervento“, that translated the english “action researchâ€. Many experiences of those times are having a continuity until today, for example the “inchiesta operaia†(worker’s inquiry) autogestionated and driven by activists or by the same people who participate of social conflicts. While the field of “applied anthropology†is being colonized by NGOs and development plans, almost always under control or even financed by the same governments, the social movements are developing some other forms of creation of knowledge.
