You will find 169 cognitive biases in this book. Some of them are already well researched, and we have only vague ideas for some. Nevertheless, this book should give you a comprehensive overview and introduction to cognitive biases. I have provided the QR-Codes to the respective biases for those who need more detailed information. In addition, I have added a chapter on "Algorithmic Biases" because the more artificial intelligence systems are used in decision-making, the more significant the topic of algorithmic biases becomes. "Let's learn more about our human biases to make less biased conclusions in the future. A world with less bias is a better world." ~ Murat Durmus
