In the academic world of universities in the United States, the rules governing how and when you may use the ideas and words of others are taken very seriously. There are widely varying cultural assumptions about how knowledge is created and legitimated, and varying norms about the treatment of existing writings by subsequent authors. The Western academic world is highly individualistic and places emphasis on being able to judge and give credit for the work of each student or researcher. "World majority" students from collectivist societies come from nations where one's experiences, thoughts and ideas are interwoven with those of others, both living and dead.
