From the perspective of science communication, this study explores how documentaries construct audiences' perceptions and attitudes toward specific scientific issues, and how to preserve accurate scientific concepts after artistic processing. In view of the high knowledge complexity and precision of genetic technology issues, which are different from the nature or environmental documentaries that focus on presentation, this paper chooses the documentary Human Nature as the main research object. This study also concerns the effects of metaphors and cognitive schema in the viewing process, such as how the film shapes the audience's impression of the scientific community and whether the presentation of ethics issues of scientific and technological is appropriate.
The study found that, in terms of technology, the narrative of this film can stimulate the audience's interest in learning, guide them to participate in the process of scientific logical inference, and stimulate their interest in learning. The open ending can also preserve the audience's thinking space after watching the film, which is helpful for the improvement of citizens' scientific literacy. But compare with the scientist Jennifer Doudna's book A Crack in Creation, this study found that on the ethical level, this film presents scientific facts one-sidedly when discussing ethical issues, and uses the metaphor of literature and science fiction to call on the audience's fear of technology. There is a risk of causing viewers to be afraid and emotional about CRISPR, which is an aspect that still needs to be handled with caution.
