Resumen:
Online video has become a relevant tool to disseminate scientific information to the public. However, in this arena, science
coexists with non-scientific or pseudoscientific beliefs that can influence people¿s knowledge, attitudes, and behavior. Our
research sets out to find empirical evidence of the representation of pro-science, anti-science and neutral stances in online
videos. From a search on Google videos, we conducted content analysis of a sample of videos about climate change,
vaccines and nanotechnology (n = 826). Results indicate that a search through Google videos provides a relatively small
representation of videos with an anti-science stance, which can be regarded as positive, given the high potential influence
of this search engine in spreading scientific information among the public. Our research also provides empirical evidence
of the fact that an anti-science stance is more frequent in user-generated content than in videos disseminated by other
types of producers.
