In the pre-holiday issue, we have prepared a real mix of topics and forms for you to elaborate on - from a clinical case through analyses of the scientific literature to several reports of original research. In my classes with students, I often emphasise how important intuition and experience are, in addition to reliable knowledge, which we must constantly update by reading, among other things, APP. The psychiatrist's intuition is certainly based precisely on knowledge and daily experience in clinical work. Do you know what 'jizz' is? I had no idea either, although when I glanced at the authors (Slawek Murawiec and Prof Trojanowski) I suspected it would be ornithological. In this article we have bird species identification, medical intuition and the theory of the brain "as a tool for making predictions". This text is thought-provoking. For encouragement, I would add that we also have statistical theories and artificial intelligence here. Real scientific jazz, full of improvisation and freedom of ideas.
