In this study, we assessed the impact of providing students with short video clips highlighting the relevance of material they are learning in the genetics classroom to their everyday lives. These interesting but non-learning objective oriented clips, referred to as "seductive details," have been studied extensively in laboratory contexts. In laboratory studies, seductive details have been shown to actually decrease learning, leading some to recommend that any information not directly pertaining to academic learning outcomes be removed from education materials. We aimed to uncover effects of seductive details in an actual college course, in a manner divorced from the confounding variation introduced by instructor-level differences in personality and lecture styles. Our results show that, in a flipped-classroom environment, seductive details do not harm students' content attainment, interest, or perceived learning, but they are memorable. Students with high background knowledge of genetics reported greater learning after watching videos containing seductive details than students who watched equivalent videos without seductive details, but there was no difference in quiz scores between the groups. These results contradict some of the major effects observed throughout decades of studies conducted in artificial psychology laboratory environments and highlight possible affective benefits of instructors using seductive details.
