The book, Inside Influence: The Psychology of Power in Human Life, examines why people increasingly entrust significant power to a small number of leaders and how this power can profoundly influence those who hold it. While Authoritarian leadership is sometimes justified as a source of stability in uncertain times, psychological research shows that power can distort judgement, reduce empathy and encourage impulsive or unethical behaviour, often making it difficult to give up. Schermuly argues that the key is not to reject power but to understand its psychological mechanisms, from the personal resources that create influence to the biological and cognitive changes triggered by gaining or losing power. He explores why certain individuals rise to power, how power can corrupt decision-making and how organisations can mitigate these risks through distributed structures, better leader selection and psychological empowerment. Rather than teaching readers how to obtain power, the book reveals how power shapes us, offering a research-based foundation for using it more responsibly and for the common good.
