Renowned brain researcher Stefan Kölsch presents the first book that explores the significance and dangers of the subconscious for our health – grounded in the latest scientific findings, accessible to everyone, and filled with numerous examples. Most processes in the brain occur unconsciously. Our subconscious quickly and automatically detects dangers or rewards, often long before we consciously recognize a given situation. Unfortunately, this unconscious thinking repeatedly makes the same mistakes: it simplifies numbers and probabilities, overestimates the value of things we own, notices flaws in others faster than in ourselves, and alters memories based on new information. Moreover, the subconscious thinking system is also an emotional system – and thus, subconscious thinking errors lead to emotional errors. They are responsible for us getting stuck in negative thought loops, entering (self-)destructive conflicts with others, and falling into unhealthy moods. In his new book, Stefan Kölsch reveals this naturally given yet often overwhelming and therefore fatal mechanism and shows how we can escape the vicious cycle of bad vibrations.
