When discussing Artificial Intelligence (AI) and its potential areas of usage, several authors use a classification of known and unknown events. Known knowns present an area in which AI can be widely used. With known unknowns and unknown unknowns (e.g. „black swan“), however, AI cannot help at all.
While this classification certainly is useful to further analyze AI usage, it is attributed to Donald Rumsfeld. Interestingly, the authors do not recollect that there is a scientific source as well: the Johari Window (see figure).
