Anthropologist Gary Weaver suggested looking at culture as a kind of iceberg: one portion is clearly visible above the surface of the water, while the much larger chunk of ice is hidden below. The part above the water can be considered surface culture––what we can physically see or hear, including behavior, words, customs, language, and traditions. Underneath the water, invisible to all, is the deep culture. This place includes our beliefs, values, assumptions, worldview, and thought processes.
