The world is confusing. Culture, history, politics present a confusing mix. But in a process of triangulation we can work out who we are and who we have been. By taking data from more than two points in time/space we can co-ordinate who we are.
Anthropologist Keith Hart explains the process. He was born in Manchester and he has spent time in North America and the Caribbean. By pulling ethnographic facts and resources from each of these three locations he was able to better understand North Atlantic culture and his own family background (source essay ‘Manchester on my Mind’).
Anthropologist are able to weave this meta data.
