Several themes describe misconceptions about mental illness and corresponding stigmatizing attitudes. Media analyses of film and print have identified three: people with mental illness are homicidal maniacs who need to be feared; they have childlike perceptions of the world that should be marveled; or they are responsible for their illness because they have weak character (29-32). Results of two independent factor analyses of the survey responses of more than 2000 English and American citizens parallel these findings (19,33):- fear and exclusion: persons with severe mental illness should be feared and, therefore, be kept out of most communities;- authoritarianism: persons with severe mental illness are irresponsible, so life decisions should be made by others;- benevolence: persons with severe mental illness are childlike and need to be cared for.- Although stigmatizing attitudes are not limited to mental illness, the public seems to disapprove persons with psychiatric disabilities significantly more than persons with related conditions such as physical illness (34-36).
