In this book, Nettle begins with an overview of how the ‘Big Five’ (extraversion, neuroticism, conscientiousness, agreeableness, openness to experience) were determined and describes how different behavioral people have different characteristics. One of the main points Nettle addresses is the difference within characteristics that make a single human being different from the other. He also points the theory of how these traits have evolved over time. From my particular interest is the question of why population? Why aren’t we all roughly the same? According to Nettle, the answer is that there is not a single optimum personality that it is always beneficial to have. The heart of the book is five chapters that investigate each trait of the ‘Big Five’. Each term is described in how it relates to the brain’s mechanism or function that it expresses. For example, people that characterize themselves high in extraversion are usually energized and enjoy being social. Professors, politicians, and entrepreneurs are all considered to be extrovert people. In the other hand, neurotic people tend to experience feelings such as guilt, panic, anger, sadness, and sometimes depression. Nettle also defines conscientiousness as the state of being comprehensive, careful, or cautious. This trait also implies the desire to seek perfection when doing tasks. Agreeableness refers to individuals whose concerns are associated with cooperation and social harmony. These individuals are often identified as friendly, considerate, generous, and kind when it comes to interacting with others. Lastly, openness to experience applies to the drive of exploring new adventures, as well as seeking to engage in new challenges. People who are high on openness to experience ... ... middle of paper ... ...luences include learned responses, unconscious thought processes, and expectations and interpretation, social-cultural influences are made of childhood experiences, influence of the situation, cultural expectations, and social support. Again, this relates back to Freud’s theory of a developing personality, stating that there are several components and influences that help shape one’s unique personality. In the last chapter of the book, Nettle explains that if these traits are constantly applied to our life, we are capable of changing our lives more than we can imagine. Yet, there are several shifts that happen during a lifespan. As we grow and mature, conscientiousness and agreeableness tend to increase within our personality, while neuroticism, openness, and extraversion decrease. This reflects changes from the desire of achieving goals to relations with others.
