A worldview, according to terror management theory (TMT), serves as a buffer against death anxiety. It is theorized that living up to the ideals of one's worldview provides a sense of self-esteem which provides a sense of transcending the limits of human life (e.g. literally, as in religious belief in immortality; symbolically, as in art works or children to live on after one's death, or in contributions to one's culture). Evidence in support of terror management theory includes a series of experiments by Jeff Schimel and colleagues in which a group of Canadians found to score highly on a measure of patriotism were asked to read an essay attacking the dominant Canadian worldview.
