In recent years, the issue of experimentation upon nonhuman animals has become the subject of media attention. One aspect of the media presentation is the status attributed to claims-makers on either side of the issue. Research suggests that perceived expertise of the source of arguments can play a role in attitudes formed by audiences. This study examines mainstream print and broadcast media presentation of the status of individuals quoted regarding the issue of animal experimentation. Those supporting continued experimentation are significantly more likely to be presented as professionals or experts. Attitude formation is discussed in light of these findings.
