According to Kathryn Schulz, her book Being Wrong is "about what happens when our beliefs, including our most fundamental, convincing, and important ones fail us" (91). She then goes into defining what belief is, and it turns out that Schulz's coverage of belief and how it works assists in illuminating why beliefs have consequences and carry weight.
Later, Schulz notes that "every one of us confuses our models of the world with the world itself--not occasionally or accidentally but necessarily" (107). That confusion and our assumptions about those who believe differently than we do explains why conflicts arise and become increasingly problematic.
