摘要
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 and other “media psychologists” would certainly be named. If we leave out the media and pop psychologists, however, and consider only those who have had an impact on psychology as a discipline, there would be no question about the outcome of this informal survey. Sigmund Freud would be the winner hands down. B. F. Skinner would finish a distant second (Roediger, 2016; Sternberg, 2016). 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 views 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 5 percent of the membership (Engel, 2008). In another major psychological association, the Association for Psychological Science, they would be even less common. 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). Developmental psychologist Alison Gopnik (2014) calls Freudian theory a zombie idea that has haunted English departments of universities long after it had nearly disappeared from psychology.
In short, modern psychology is not obsessed with the ideas of Sigmund Freud, 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 concern modern psychologists. This larger body of research and theory encompasses the work of 5 Nobel Prize winners (David Hubel, Daniel Kahneman, Herbert Simon, Roger Sperry, and Torsten Wiesel) and 17 winners of the National Medal of Science (Lowman & Benjamin, 2012), 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. In fact, Freud’s methods give 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. As one historian of psychotherapy has noted, “If Freud himself was a scientist, it was a strange science he was promulgating. . . . Psychoanalysis contained theories and hypotheses, but it lacked a method of empirical observation” (Engel, 2008, p. 17).
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 (Boudry & Buekens, 2011; Dufresne, 2007; Engel, 2008). 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. Second, we shall discuss what features are common to psychological investigations across a wide variety of domains (features missing from Freud’s work). We will see that there is one unifying characteristic of modern psychology: the quest to understand behavior by using the methods of science.
