　　New to the Tenth Edition
　　The tenth edition of How to Think Straight About Psychology has no major structural revisions because a chapter reorganization occurred in a previous edition. The content and order of the chapters remain the same. At the request of reviewers and users, this edition remains at the same length as the ninth edition. Readers and users have not wanted the book to lengthen and, indeed, it has not. I have continued to update and revise the examples that are used in the book (while keeping those that are reader favorites).
　　Some dated examples have been replaced with more contemporary studies and issues. I have made a major effort to use contemporary citations that are relevant to the various concepts and experimental effects that are mentioned. A large number of new citations appear in this edition (172 new citations, to be exact!), so that the reader continues to have up-to-date references on all of the examples and concepts.
　　The goal of the book remains what it always was—to present a short introduction to the critical thinking skills that will help the student to better understand the subject matter of psychology. During the past decade and a half there has been an increased emphasis on the teaching of critical thinking in universities (Abrami et al., 2008; Sternberg, Roediger, & Halpern, 2006). Indeed, some state university systems have instituted curricular changes mandating an emphasis on critical thinking skills. At the same time, however, other educational scholars were arguing that critical thinking skills should not be isolated from specific factual content. How to Think Straight About Psychology combines these two trends. It is designed to provide the instructor with the opportunity to teach critical thinking within the rich content of modern psychology.

　　There exists a body of knowledge that is unknown to most people. This information concerns human behavior and consciousness in their various forms. It can be used to explain, predict, and control human actions. Those who have access to this knowledge use it to gain an understanding of other human beings. They have a more complete and accurate conception of what determines the behavior and thoughts of other individuals than do those
　　who do not have this knowledge.
　　Surprisingly enough, this unknown body of knowledge is the discipline of psychology.
　　What can I possibly mean when I say that the discipline of psychology is unknown? Surely, you may be thinking, this statement was not meant to be taken literally. Bookstores contain large sections full of titles dealing with psychology. Television and radio talk shows regularly feature psychological topics. Magazine articles quote people called psychologists talking about a variety of topics. Nevertheless, there is an important sense in which the field of psychology is unknown.
　　Despite much seeming media attention, the discipline of psychology remains for the most part hidden from the public. The transfer of “psychological” knowledge that is taking place via the media is largely an illusion. Few people are aware that the majority of the books they see in the psychology sections of many bookstores are written by individuals with absolutely no standing in the psychological community. Few are aware that many of the people to whom television applies the label psychologist would not be considered so by the American Psychological Association or the Association for Psychological Science. Few are aware that many of the most visible psychological “experts” have contributed no information to the fund of knowledge in the discipline of psychology.
　　The flurry of media attention paid to “psychological” topics has done more than simply present inaccurate information. It has also obscured the very real and growing knowledge base in the field of psychology. The general public is unsure about what is and is not psychology and is unable to independently evaluate claims about human behavior. Adding to the problem is the fact that many people have a vested interest in a public that is either without evaluative skills or that believes there is no way to evaluate psychological claims. The latter view, sometimes called the “anything goes” attitude, is one of the fallacies discussed in this book, and it is particularly costly to the public. Many pseudosciences are multimillion-dollar industries that depend on the lack of public awareness that claims about human behavior can be tested. The general public is also unaware that many of the claims made by these pseudosciences (e.g., astrology, psychic surgery, speed reading, biorhythms, therapeutic touch, subliminal self-help tapes, facilitated communication, and psychic detectives) have been tested and proved false. The existence of the pseudoscience industry, which is discussed in this book, increases the media’s tendency toward sensationalistic reporting of science. This tendency is worse in psychology than in other sciences, and
　　understanding the reasons why this is so is an important part of learning how to think straight about psychology.
　　This book, then, is directed not at potential researchers in psychology but at a much larger group: the consumers of psychological information. The target audience is the beginning psychology student and the general reader who have encountered information on psychological issues in the general media and have wondered how to go about evaluating its validity.
　　This book is not a standard introductory psychology text. It does not outline a list of facts that psychological research has uncovered. Indeed, telling everyone to take an introductory psychology course at a university is probably not the ultimate solution to the inaccurate portrayal of psychology in the media. There are many laypeople with a legitimate interest in psychology who do not have the time, money, or access to a university to pursue formal study. More importantly, as a teacher of university-level psychology courses, I am forced to admit that my colleagues and I often fail to give our beginning students a true understanding of the science of psychology. The reason is that lower-level courses often do not teach the critical analytical skills that are the focus of this book. As instructors, we often become obsessed with “content”—with “covering material.” Every time we stray a little from the syllabus to discuss issues such as psychology in the media, we feel a little guilty and begin to worry that we may not cover all the topics before the end of the term.
　　Consider the average introductory psychology textbook. Many now contain between 600 and 800 multicolumned pages and reference literally hundreds of studies in the published literature. Of course, there is nothing wrong with such books containing so much material. It simply reflects the increasing knowledge base in psychology. There are, however, some unfortunate side effects. Instructors are often so busy trying to cram their students full of dozens of theories, facts, and experiments that they fail to deal with some of the fundamental questions and misconceptions that students bring with them to the study of psychology. Rather than dealing directly with these misconceptions, the instructors (and the introductory textbook authors) often hope that if students are exposed to enough of the empirical content of psychology, they will simply induce the answers to their questions. In short, the instructors hope that students will recognize the implicit answers to these questions in the discussions of empirical research in several content areas. All too often this hope is frustrated. In a final review session—or in office hours at the end of the term—instructors are often shocked and discouraged by questions and comments that might have been expected on the first day of the course but not after 14 weeks: “But psychology experiments aren’t real life; what can they tell us?”; “Psychology just can’t be a real science like chemistry, can it?”; “But I heard a therapist on TV say the opposite of what our textbook said”; “I think this theory isstupid—my brother behaves just the opposite of what it says”; “Psychology is nothing more than common sense, isn’t it?”; “Everyone knows what anxiety
　　is—why bother defining it?” For many students, such questions are not implicitly answered merely by a consideration of the content of psychology. In this book, I deal explicitly with the confusions that underlie questions and comments such as these.
　　Unfortunately, research has shown that the average introductory psychology course does surprisingly little to correct some of entering students’ misconceptions about the discipline (Keith & Beins, 2008; Kowalski & Taylor, 2009; Standing & Huber, 2003; Taylor & Kowalski, 2004). This unfortunate fact provides the rationale for this book. Psychology students need explicit instruction in the critical thinking skills that will make them into independent evaluators of psychological information.
　　Years after students have forgotten the content of an introductory psychology course, they will still use the fundamental principles covered in this book to evaluate psychological claims. Long after Erikson’s stages of development have been forgotten, students will be using the thinking tools introduced in this text to evaluate new psychological information encountered in the media. Once acquired, these skills will serve as lifelong tools that will aid in the evaluation of knowledge claims. First, they provide the ability to conduct an initial gross assessment of plausibility. Second, these skills provide some criteria for assessing the reliability of “expert” opinion.

　　The Freud Problem
　　Stop 100 people on the street and ask them to name a psychologist, either living or dead. Record the responses. Of course, Dr. Phil, Wayne Dyer, and other “media psychologists” would certainly be named. If we leave out the media and pop psychologists, however, and consider only those who have made a recognized contribution to psychological knowledge, there would be no question about the outcome of this informal survey. Sigmund Freud would be the winner hands down. B. F. Skinner would probably finish a distant second. No other psychologist would get enough recognition even to
　　bother about. Thus, Freud, along with the pop psychology presented in the media, largely defines psychology in the public mind.
　　The notoriety of Freud has greatly affected the general public’s conceptions about the field of psychology and has contributed to many misunderstandings. For example, many introductory psychology students are surprised to learn that, if all the members of the American Psychological Association (APA) who were concerned with Freudian psychoanalysis were collected, they would make up less than 10 percent of the membership. In another major psychological association, the Association for Psychological Science, they would make up considerably less than 5 percent. One popular introductory psychology textbook (Wade & Tavris, 2008) is over 700 pages long, yet contains only 15 pages on which either Freud or psychoanalysis is mentioned—and these 15 pages often contain
　　criticism (“most Freudian concepts were, and still are, rejected by most empirically oriented psychologists,” p. 19).
　　In short, modern psychology is not obsessed with the ideas of Sigmund Freud (as are the media and some humanities disciplines), nor is it largely defined by them. Freud’s work is an extremely small part of the varied set of issues, data, and theories that are the concern of modern psychologists. This
　　larger body of research and theory encompasses the work of five recent Nobel Prize winners (David Hubel, Daniel Kahneman, Herbert Simon, Roger Sperry, and Torsten Wiesel) and a former director of the National Science Foundation (Richard Atkinson), all of whom are virtually unknown to the public.
　　It is bad enough that Freud’s importance to modern psychology is vastly exaggerated. What makes the situation worse is that Freud’s methods of investigation are completely unrepresentative of how modern psychologists conduct their research (recall that Freud began his work over a hundred years ago). In fact, the study of Freud’s methods gives an utterly misleading impression of psychological research. For example, Freud did not use controlled experimentation, which, as we shall see in Chapter 6, is the most potent weapon in the modern psychologist’s arsenal of methods. Freud thought that case studies could establish the truth or falsity of theories. We shall see in Chapter 4 why this idea is mistaken. Finally, a critical problem with Freud’s work concerns the connection between theory and behavioral data. As we shall see in Chapter 2, for a theory to be considered scientific, the link between the theory and behavioral data must meet some minimal requirements. Freud’s theories do not meet these criteria (Dufresne, 2007; Hines, 2003; Macmillan, 1997; McCullough, 2001). To make a long story short, Freud built an elaborate theory on a database (case studies and introspection) that was not substantial enough to support it. Freud concentrated on building complicated theoretical structures, but he did not, as modern psychologists do, ensure that they would rest on a database of reliable, replicable behavioral relationships. In summary, familiarity with Freud’s style of work can be a significant impediment to the understanding of modern psychology.
　　In this chapter, we shall deal with the Freud problem in two ways. First, when we illustrate the diversity of modern psychology, the rather minor position occupied by Freud will become clear (see Haggbloom et al., 2002; Robins, Gosling, & Craik, 1999, 2000). Second, we shall discuss what features are common to psychological investigations across a wide variety of domains. A passing knowledge of Freud’s work has obscured from the general public what is the only unifying characteristic of modern psychology: the quest to understand behavior by using the methods of science.
　　The Diversity of Modern Psychology
　　There is, in fact, a great diversity of content and perspectives in modern psychology. This diversity drastically reduces the coherence of psychology as a discipline. Henry Gleitman (1981), winner of the American Psychological Foundation’s Distinguished Teaching Award, characterized psychology as “a loosely federated intellectual empire that stretches from the domains of the biological sciences on one border to those of the social sciences on the other” (p. 774). Commentators outside of psychology have criticized this diversity. For example, anthropologist Clifford Geertz (2000) has complained that “from the outside, at least, it does not look like a single field, divided into schools and specialties in the usual way. It looks like an assortment of disparate and disconnected inquiries classed together because they all make reference in some way or other to something or other called mental
　　functioning” (p. 187).
　　Understanding that psychology is composed of an incredibly wide and diverse set of investigations is critical to an appreciation of the nature of the discipline. Simply presenting some of the concrete indications of this diversity will illustrate the point. The APAhas 54 different divisions, each representing either a particular area of research and study or a particular area of practice (see Table 1.1). From the table, you can see the range of subjects studied by psychologists, the range of settings involved, and the different aspects of behavior studied. The other large organization of psychologists—the Association for Psychological Science—is just as diverse. Actually, Table 1.1 understates the diversity within the field of psychology because it gives the impression that each division is a specific specialty area. In fact, each of the 54 divisions listed in the table is a broad area of study that contains a wide variety of subdivisions! In short, it is difficult to exaggerate the diversity of the topics that fall within the field of psychology.
