Drawing on a thorough examination of case law, as well as extensive empirical research, including surveys involving over 4,000 members of the general public, interviews with judges and legal practitioners and focus groups representing various sections of the community, this book concludes that the law reflects fundamental misperceptions about what people think and how they are influenced by the media. The result is that the law tends to operate so as to unfairly disadvantage publishers, thus contributing to defamation law's infamous 'chilling effect' on free speech.
