Dariusz Galasinski employs a discourse analytical approach to the study of deception in The Language of Deception. The book focuses on the deceptive messages themselves -- how language is used to deceive others and what kinds of linguistic devices are used.

Galasinski develops a theory of deception based on his extensive study of debates and interviews of American and British politicians. Actual exchanges such as one in which a politician is asked the same question 14 times and evades it 14 times provide fascinating insight into deceptive linguistic practices.
