Extending previous research on how science fiction viewing and science news use predict attitudes toward a range of emerging technologies, this study draws on theories of genre-specific cultivation and narrative transportation to analyze how media consumption predicts attitudes toward two speculative technologies: mind uploading and terraforming. Results from a survey of the U.S. public (N = 1,015) show that science fiction viewing was positively related to support for mind uploading, while science fiction transportation was positively related to support for terraforming, belief that people are likely to develop mind uploading, and belief that people are likely to develop terraforming. Transportation also mediated relationships between science fiction viewing and attitudes. In addition, science news use was positively related to support for each technology and belief that people are likely to develop each technology. These findings highlight the potential role of media factors in predicting attitudes about hypothetical technologies.
