The blending of entertainment and education is often used as a mechanism for communicating science to the general public. Key to dissemination of scientific information is cognitive engagement of the audience with the content. The authors describe a study investigating the relationship between entertaining videos and cognitive engagement of the viewer on a topic associated with climate change. Two identical videos discussing the science of climate change were created, with one video containing additional content that was entertaining and based on popular cultural references. Viewers completed an online survey (n = 472) and the data demonstrated that there was no direct link between presentation of the climate change information in an entertaining video and an individual’s level of cognitive engagement with the content. Further, that an indirect link was identified so that perceived entertainment increased cognitive engagement. These findings may be useful for communicators of environmental issues, especially with consideration of the development of the field of edutainment.
