Kumashiro defines common sense simply as what everyone should know. Common sense is often information that we take for granted and assume that everyone possesses. As Kumarshiro discovers, common sense can vary around the world. It seems to be something that does not remain constant from region to region. It appears to directly correlate with economics, culture, and climate. Even something as simple as growing up in a rural setting may dictate that my common sense may differ from that of a person who grew up within an urban center. Common sense is vital because it is something that we apply daily within our interactions with others. It also is something that we should possess to function effectively within society.
