The psychologist's fallacy is an informal fallacy that occurs when an observer assumes that his or her subjective experience reflects the true nature of an event. The fallacy was named by William James in the 19th century:
The great snare of the psychologist is the confusion of his own standpoint with that of the mental fact about which he is making his report. I shall hereafter call this the 'psychologist's fallacy' par excellence. [1]
Some sources state the psychologist's fallacy as if it were about two people—the observer and the observed—rather than about one observer and a fact. For example,
Psychologist's fallacy, the fallacy, to which the psychologist is peculiarly liable, of reading into the mind he is examining what is true of his own; especially of reading into lower minds what is true of higher. [2]
A danger to be avoided known as the 'psychologist's fallacy'. This arises from the fact that the experimenter is apt to suppose that the subject will respond to a stimulus or an order in the same way as he himself would respond in the circumstances. [3]
In this alternative form, the fallacy is described as a specific form of the "similar to me" stereotype: what is unknown about another person is assumed, for simplicity, using things the observer knows about themself. Such a bias leads the observer to presuppose knowledge or skills, or lack of such, possessed by another person. For example, "I (or everyone I know or most people I know) don't know very much about chemistry. Therefore I can assume that this other person knows very little about chemistry." This assumption may be true in any number of specific cases, making inductive reasoning based on this assumption cogent, but is not applicable in the general case (there are many people who are very knowledgeable in the field of chemistry), and therefore deductive reasoning based on this assumption may be invalid.
These alternative statements, however, do not match what William James characterized when he named the fallacy. [1]
Victor Frankl (1946) "Man's Search for Meaning":
Logotherapy is neither teaching nor preaching. It is as far removed from logical reasoning as it is from moral exhortation.
To put it figuratively, the role played by a logotherapist is that of an eye specialist rather than that of a painter. A painter tries to convey to us a picture of the world as he sees it; an ophthalmologist tries to enable us to see the world as it really is.
The logotherapist’s role consists of widening and broadening the visual eld of the patient so that the whole spectrum of potential meaning becomes conscious and visible to him. [4]
In metaethics, the naturalistic fallacy is the claim that it is possible to define good in terms of merely described entities, properties, or processes such as pleasant, desirable, or fitness. The term was introduced by British philosopher G. E. Moore in his 1903 book Principia Ethica.
Reason is the capacity of consciously applying logic by drawing valid conclusions from new or existing information, with the aim of seeking the truth. It is associated with such characteristically human activities as philosophy, religion, science, language, mathematics, and art, and is normally considered to be a distinguishing ability possessed by humans. Reason is sometimes referred to as rationality.
In classical rhetoric and logic, begging the question or assuming the conclusion is an informal fallacy that occurs when an argument's premises assume the truth of the conclusion. Historically, begging the question refers to a fault in a dialectical argument in which the speaker assumes some premise that has not been demonstrated to be true. In modern usage, it has come to refer to an argument in which the premises assume the conclusion without supporting it. This makes it an example of circular reasoning.
Deductive reasoning is the process of drawing valid inferences. An inference is valid if its conclusion follows logically from its premises, meaning that it is impossible for the premises to be true and the conclusion to be false. For example, the inference from the premises "all men are mortal" and "Socrates is a man" to the conclusion "Socrates is mortal" is deductively valid. An argument is sound if it is valid and all its premises are true. One approach defines deduction in terms of the intentions of the author: they have to intend for the premises to offer deductive support to the conclusion. With the help of this modification, it is possible to distinguish valid from invalid deductive reasoning: it is invalid if the author's belief about the deductive support is false, but even invalid deductive reasoning is a form of deductive reasoning.
William James was an American philosopher and psychologist, and the first educator to offer a psychology course in the United States. James is considered to be a leading thinker of the late 19th century, one of the most influential philosophers of the United States, and the "Father of American psychology."
A faulty generalization is an informal fallacy wherein a conclusion is drawn about all or many instances of a phenomenon on the basis of one or a few instances of that phenomenon. It is similar to a proof by example in mathematics. It is an example of jumping to conclusions. For example, one may generalize about all people or all members of a group from what one knows about just one or a few people:
Man's Search for Meaning is a 1946 book by Viktor Frankl chronicling his experiences as a prisoner in Nazi concentration camps during World War II, and describing his psychotherapeutic method, which involved identifying a purpose to each person's life through one of three ways: the completion of tasks, caring for another person, or finding meaning by facing suffering with dignity.
Logical reasoning is a mental activity that aims to arrive at a conclusion in a rigorous way. It happens in the form of inferences or arguments by starting from a set of premises and reasoning to a conclusion supported by these premises. The premises and the conclusion are propositions, i.e. true or false claims about what is the case. Together, they form an argument. Logical reasoning is norm-governed in the sense that it aims to formulate correct arguments that any rational person would find convincing. The main discipline studying logical reasoning is logic.
Logotherapy is a form of existential therapy developed by neurologist and psychiatrist Viktor Frankl. It is founded on the premise that the primary motivational force of individuals is to find meaning in life. Frankl describes it as "the Third Viennese School of Psychotherapy" along with Freud's psychoanalysis and Alfred Adler's individual psychology.
A cognitive distortion is a thought that causes a person to perceive reality inaccurately due to being exaggerated or irrational. Cognitive distortions are involved in the onset or perpetuation of psychopathological states, such as depression and anxiety.
The Barnum effect, also called the Forer effect or, less commonly, the Barnum–Forer effect, is a common psychological phenomenon whereby individuals give high accuracy ratings to descriptions of their personality that supposedly are tailored specifically to them, yet which are in fact vague and general enough to apply to a wide range of people. This effect can provide a partial explanation for the widespread acceptance of some paranormal beliefs and practices, such as astrology, fortune telling, aura reading, and some types of personality tests.
The Blank Slate: The Modern Denial of Human Nature is a best-selling 2002 book by the cognitive psychologist Steven Pinker, in which the author makes a case against tabula rasa models in the social sciences, arguing that human behavior is substantially shaped by evolutionary psychological adaptations. The book was nominated for the 2003 Aventis Prizes and was a finalist for the Pulitzer Prize.
Informal fallacies are a type of incorrect argument in natural language. The source of the error is not just due to the form of the argument, as is the case for formal fallacies, but can also be due to their content and context. Fallacies, despite being incorrect, usually appear to be correct and thereby can seduce people into accepting and using them. These misleading appearances are often connected to various aspects of natural language, such as ambiguous or vague expressions, or the assumption of implicit premises instead of making them explicit.
The intentional stance is a term coined by philosopher Daniel Dennett for the level of abstraction in which we view the behavior of an entity in terms of mental properties. It is part of a theory of mental content proposed by Dennett, which provides the underpinnings of his later works on free will, consciousness, folk psychology, and evolution.
Here is how it works: first you decide to treat the object whose behavior is to be predicted as a rational agent; then you figure out what beliefs that agent ought to have, given its place in the world and its purpose. Then you figure out what desires it ought to have, on the same considerations, and finally you predict that this rational agent will act to further its goals in the light of its beliefs. A little practical reasoning from the chosen set of beliefs and desires will in most instances yield a decision about what the agent ought to do; that is what you predict the agent will do.
Appeal to the stone, also known as argumentum ad lapidem, is a logical fallacy that dismisses an argument as untrue or absurd. The dismissal is made by stating or reiterating that the argument is absurd, without providing further argumentation. This theory is closely tied to proof by assertion due to the lack of evidence behind the statement and its attempt to persuade without providing any evidence.
Bulverism is a type of ad hominem rhetorical fallacy that combines circular reasoning and the genetic fallacy with presumption or condescension. The Bulverist assumes a speaker's argument is invalid or false and then explains why the speaker came to make that mistake or to be so silly by attacking the speaker or the speaker's motive.
Implicit personality theory describes the specific patterns and biases an individual uses when forming impressions based on a limited amount of initial information about an unfamiliar person. While there are parts of the impression formation process that are context-dependent, individuals also tend to exhibit certain tendencies in forming impressions across a variety of situations. There is not one singular implicit personality theory utilized by all; rather, each individual approaches the task of impression formation in his or her own unique way. However, there are some components of implicit personality theories that are consistent across individuals, or within groups of similar individuals. These components are of particular interest to social psychologists because they have the potential to give insight into what impression one person will form of another.
Reification is a fallacy of ambiguity, when an abstraction is treated as if it were a concrete real event or physical entity. In other words, it is the error of treating something that is not concrete, such as an idea, as a concrete thing. A common case of reification is the confusion of a model with reality: "the map is not the territory".
Evolutionary psychology seeks to identify and understand human psychological traits that have evolved in much the same way as biological traits, through adaptation to environmental cues. Furthermore, it tends toward viewing the vast majority of psychological traits, certainly the most important ones, as the result of past adaptions, which has generated significant controversy and criticism from competing fields. These criticisms include disputes about the testability of evolutionary hypotheses, cognitive assumptions such as massive modularity, vagueness stemming from assumptions about the environment that leads to evolutionary adaptation, the importance of non-genetic and non-adaptive explanations, as well as political and ethical issues in the field itself.
