Experience makes one wise, says a proverb. Without mistakes and errors, there is no development. However, the current zero-error culture struggles to accept mistakes. Until now, humans, as fragile beings in the delicate structure of the world, have relied primarily on experience to correct and limit their errors and mistakes. In light of the rapid increase in abstract knowledge against the backdrop of virtual worlds, it is becoming increasingly difficult to have tangible experiences. As a result, managing mistakes is increasingly overwhelming. Does the antiquated human in a zero-error culture mutate into the greatest conceivable accident and risk factor? Is this why there is relentless work on perfecting oneself? Manfred Osten raises the fundamental question of the relativity of our rationally oriented Western understanding of mistakes.
