What is ethnographic present?

The timeless ethnographic present is the concept of studying a people as you can view them at a specific time and then writing about it, in an ethnography, as if it was how they always were. It is the lack of the historical view of a people and is often thought of in modern anthropology in a bad way because it assumes that primitive peoples don't have a history in the same way we do and that they exist in this constant state, the timeless ethnographic present.
