If you look at our society you will see a number of social problems that are difficult to change through social work or by politics. Thus, the increasing aggression in our society seems to be unstoppable. Football vandals destroy train after train and senseless violence seems to make sense for some people. In this book you will see that there is an underlying basis to human behavior that is mostly not mentioned. That basis is made up of a number of biological factors. Can more insight into these biological factors lead to a better world? This book and the website want to provide an answer to that question.
