HRAF Advanced Research Centers

About hrafARC

The HRAF Advanced Research Centers (hrafARC) aim to promote basic and applied research in anthropology and to encourage and support comparative and cross-cultural research. More specifically, hrafARC aims to further the development of anthropology through comparative knowledge based on testable theory, sound research design and systematic methods for the collection and analysis of data. We seek to fulfill the historic mission of anthropology to describe and explain the range of variation in human biology, society, and culture across time and space. 

The main headquarters is at the Human Relations Area Files (HRAF) building in New Haven, CT (755 Prospect Street).  HRAF is a nonprofit membership consortium affiliated with Yale University.  Carol R. Ember directs hrafARC in New Haven and Michael Fischer directs hrafARC  in the UK--see

hrafARC Projects

Natural Hazards and Cultural Transformations. (2015-2019)

Researchers from cultural anthropology, archaeology, psychology, geography and climatology conducted three types of comparisons--a worldwide cross-cultural comparison using ethnographic data, an diachronic archaeological comparison of 32 traditions before and after major severe climate events, and a comparison of countries.  We are looking at a broad variety of possible cultural transformations in response to hazards.  These range from diet and subsistence diversity, property systems, mutual aid, political economy, general cultural “tightness" and beliefs about gods involvement with weather.  All of these domains have been newly coded for this project.   Read more ...

Social Resilience to Nuclear Winter. (2018-2020)

This project employs archaeological and historical information to examine societal resilience to a catastrophic atmospheric event that block the sun and cooled the Northern Hemisphere by roughly 1 degree centigrade, creating widespread social disruption.  Peregrine uses this event as a proxy for the expected atmospheric impact of a limited nuclear war in Europe and seeks to identify strategies of resilience by examining those societies that survived, and failed to survive, the A.D. 536 event.  Read more...
