This letter was written by José Nun in November 1968. It was his public response to the objections raised by other researchers concerning the ethical standards with which he had conducted the Social Marginalization Project. Fifty years have passed since José Nun carried out said study. This letter was first published by Casa de las Americas in 1971, and is still today a key reference concerning the issue of research integrity. In fact, it could be argued this is one of the first documents that addressed research integrity in social sciences within the Latin-American context. In many respects, the ethical considerations taken by José Nun for conducting the study (autonomy, independence, proper data handling, among others) match the guidelines established by Ethics Committees nowadays.
