Three forms of leadership are frequently identified as prerequisites to the re-humanization of the healthcare system: ‘authentic leadership’, ‘mindful leadership’ and ‘ethical leadership’. In different ways and to varying extents, these approaches all focus on person- or human-centred caring. In a phenomenological action research project at a Danish hospital, the nurses experienced and then described how developing a conscious sense of wonder enhanced their ability to hear, to get in resonance with the existential in their meetings with patients and relatives, (...) and to respond ethically. This ability was fostered through so-called Wonder Labs in which the notion of ‘phenomenon-led care’ evolved, which called for ‘slow thinking’ and ‘slow wondrous listening’. For the 10 nurses involved, it proved challenging to find the necessary serenity and space for this slow and wonder-based practice. This article critiques and examines, from a theoretical perspective, the kind of leadership that is needed to encourage this wonder-based approach to nursing, and it suggests a new type of leadership that is itself inspired by wonder and is guided by 10 tangible elements.
