I see the question this way: Everything we learn, is culture (at least individually), most of it is prevalent in our environment (time and place) and therefore could be labeled as part of the societal culture. An then, there could be a quest to see if this that we learn, reflects what we arbitrary deem as proper of the "un-contaminated", or "un-spoiled" traditions from some society or place.
