This method helps participants to consider perspectives and worldviews that are not necessarily human-centred. It does this by giving these other entities (plants, animals, buildings, products, systems) a voice in debates, around the discussion table, across different meetings, and across different locations. It can involve role-play, but it is not only based on one person taking another identity for a short period of time. It relates on a thorough, often interdisciplinary research about a non-human of interest, and within the biophysical, cultural and specific project/stakeholder context. It is a powerful tool that is able to open up perspectives that usually stay invisible and therefore neglected.
