From Personal to Collective: Using Digital Storytelling to Unlock Grassroots Knowledge Psychologist Jerome Bruner said that narrative is a “principle by which people organize their experience in, knowledge about, and transactions with the social world.” Stories make information more understandable, memorable, and persuasive, unlocking grassroots knowledge and using the power of emotions to shape decisions. Digital storytelling has also emerged as an effective action research method to engage communities in collective participation and action, grounded in their sense of place and their distinctive cultural knowledge. As a tool, digital storytelling can challenge hierarchies of expertise, amplify unheard voices, and convey important emotions.
