ABSTRACT
Gullibility seems to be a fundamental characteristic of human beings. Although the ability to share information with others is one the major evolutionary achievements of our species, this symbolic ability can also be a major source of gullibility. Understanding the processes that lead to gullibility is of growing importance in public life. This introductory chapter will discuss the nature, functions, and social and cultural history of human gullibility. In particular, the evolutionary significance and contemporary relevance of gullibility will be considered, and the psychological processes that contribute to credulity will be reviewed. The chapter concludes with a brief overview of the book.
