Manipulations are present everywhere in daily life, as it is impossible not to manipulate! Both personality diagnostics and the analysis of social systems and processes focus on these social stages, which are subject to mutual influences, and this book deals with extensively. Traditionally, psychological diagnostics either use so-called lie scales or measure conspicuous bodily signals, such as polygraphs, to uncover attempts at manipulation or deception. Differentially diagnosed personality profiles generally round off the assessment of individuals. System-relevant analyses in social situations examine interactions between competing parties that want to achieve their influencing or action strategies through rational moves and observe the processes from a higher level. You will learn about the insights from the diagnostics of manipulations that you can benefit from as a reader in this reading. Target Groups: Executives, HR experts in academia and practice, and specialists who need to assess the credibility of statements based on fiction and truth or are involved in other support mandates.
