Haunting Messages: Online Videos and Public Belief in Paranormal Phenomena.

Despite broad skepticism within the scientific community regarding paranormal phenomena such as ghosts and unidentified flying objects (UFOs), many members of the public believe in these phenomena. Previous studies have argued that viewing paranormal-themed television-including documentary, reality, and news programming-can cultivate such beliefs. In addition, recent research suggests that the online video-sharing platform YouTube may serve as an important source of messages about fringe phenomena.

Wedding Imagery and Public Support for Gay Marriage.

This study uses an experiment embedded in a large, nationally representative survey to test whether exposure to imagery of a gay or lesbian couple's wedding influences support for gay marriage. It also tests whether any such effects depend on the nature of the image (gay or lesbian couple, kissing or not) and viewer characteristics (sex, age, race, education, religion, and ideology). Results show that exposure to imagery of a gay couple kissing reduced support for gay marriage relative to the baseline.

Contested evidence: Exposure to competing scientific claims and public support for banning bisphenol A.

The public controversy surrounding bisphenol A (BPA) revolves around competing claims about what scientific evidence shows regarding the effects of the chemical on human health. This study uses an experiment embedded within a public opinion survey to test the effects of exposure to such claims on public support for banning the use of BPA in products. Exposure to the claim that "there is not enough scientific evidence that BPA harms human health" reduced support, whereas exposure to the claim that there "is enough scientific evidence" failed to increase support.

Investigating CSI: portrayals of DNA testing on a forensic crime show and their potential effects.

The popularity of forensic crime shows such as CSI has fueled debate about their potential social impact. This study considers CSI's potential effects on public understandings regarding DNA testing in the context of judicial processes, the policy debates surrounding crime laboratory procedures, and the forensic science profession, as well as an effect not discussed in previous accounts: namely, the show's potential impact on public understandings of DNA and genetics more generally. To develop a theoretical foundation for research on the "CSI effect," it draws on cultivation theory, social cognitive theory, and audience reception studies.
