Chapter One Summary

The first chapter of "Psychology: From Inquiry to Understanding" is an introduction to the field of psychology. It defines psychology as "the scientific study of the brain, mind and behavior." I really enjoyed this chapter, because it gave a very clear overview of the field and raised questions in an engaging way. I also liked the persuasive style of writing- the sharp criticism of pseudoscience and logical fallacies were especially interesting.
The chapter explains that the psychology goes much deeper than common sense or intuition: it is a scientific field. The writers also acknowledge that psychology is difficult to study and difficult to define. This chapter explains the levels of analysis, which can be used to define the study. The levels of analysis are likened to "rungs on a ladder," the lowest of which is biological influences. The highest level is the social level.
Chapter one also goes into depth on the challenges of psychology, noting that "human behavior is difficult to predict" because actions are multiply determined, that is, there are many factors that go into the final result. It delves into the common errors of popular psychology, including attributing complex behaviors to a single factor. It enlightens us in common errors of common sense, such as the contradictions of famous proverbs. It presents the concept of naïve realism (believing we see the world exactly how it is) and stresses the need for critical thinking: the ability to evaluate claims with an open mind, yet carefully. The chapter also highlights scientific theory, the scientific method and how they are applied to psychology. It presents science as a "safeguard against bias," particularly confirmation bias (the tendency to look for evidence that supports one's own claim, and dismiss findings that contradict it) and belief perseverance (the tendency to cling to one's initial beliefs, even when faced with contradictory evidence).
This chapter also places metaphysical claims (beliefs about the world that cannot be tested) squarely out of the scientific realm. In short, the authors do not refute metaphysical claims, but assert that since they cannot be tested, they lie outside the boundaries of science.
Chapter one also addresses psychological pseudoscience: it is defined as a "set of claims that seem scientific but aren't." Its lack of prevention against confirmation bias and belief perseverance make it particularly untrustworthy, and as the writers assert, dangerous and even deadly. The authors state that the reason humans are drawn to pseudoscience stems from an innate tendency to draw sense from nonsense and order from disorder. Our brains are predisposed towards it.
Chapter one also includes the necessity of scientific thinking. It describes scientific thinking as the "approach of evaluating all claims with an open mind, but insisting on persuasive evidence before accepting them."
This chapter also includes the history of psychology and its early leading figures. It introduces the early theoretic perspectives: what they contributed and how they continue to influence psychology today.
This chapter also discusses the "multifaceted world of modern psychology." It explains the types of psychologists that practice today and the steady growth of the field. It includes the big debates of psychology: nature versus nurture and free will versus determinism. Finally, the chapter concludes with examples with how psychology has impacted our daily lives- from paving the way to school integration to choosing the color of fire trucks to the more nocturnally visible color of lime- yellow.
