A cognitive bias is a systematic pattern of deviation from norm or rationality in judgment. Individuals create their own "subjective reality" from their perception of the input. An individual's construction of reality, not the objective input, may dictate their behavior in the world. Thus, cognitive biases may sometimes lead to perceptual distortion, inaccurate judgment, illogical interpretation, or what is broadly called irrationality.
Confirmation bias is the tendency to search for, interpret, favor, and recall information in a way that confirms or supports one's prior beliefs or values. People display this bias when they select information that supports their views, ignoring contrary information, or when they interpret ambiguous evidence as supporting their existing attitudes. The effect is strongest for desired outcomes, for emotionally charged issues, and for deeply entrenched beliefs. Confirmation bias cannot be eliminated, but it can be managed, for example, by education and training in critical thinking skills.
Holocaust denial is an antisemitic conspiracy theory that falsely asserts that the Nazi genocide of Jews, known as the Holocaust, is a myth, fabrication, or exaggeration. Holocaust denial involves making one or more of the following false statements:
In the field of psychology, cognitive dissonance is the perception of contradictory information and the mental toll of it. Relevant items of information include a person's actions, feelings, ideas, beliefs, values, and things in the environment. Cognitive dissonance is typically experienced as psychological stress when persons participate in an action that goes against one or more of those things. According to this theory, when two actions or ideas are not psychologically consistent with each other, people do all in their power to change them until they become consistent. The discomfort is triggered by the person's belief clashing with new information perceived, wherein the individual tries to find a way to resolve the contradiction to reduce their discomfort.

Fragments: Memories of a Wartime Childhood is a 1995 book, whose author used the pseudonym Binjamin Wilkomirski, which purports to be a memoir of the Holocaust. It was debunked by Swiss journalist and writer Daniel Ganzfried in August 1998. The subsequent disclosure of Wilkomirski's fabrications sparked heated debate in the German- and English-speaking world. Many critics argued that Fragments no longer had any literary value. Swiss historian and anti-Semitism expert Stefan Maechler later wrote, "Once the professed interrelationship between the first-person narrator, the death-camp story he narrates, and historical reality are proved palpably false, what was a masterpiece becomes kitsch."
In psychology, the false consensus effect, also known as consensus bias, is a pervasive cognitive bias that causes people to “see their own behavioral choices and judgments as relatively common and appropriate to existing circumstances”. In other words, they assume that their personal qualities, characteristics, beliefs, and actions are relatively widespread through the general population.
Elliot Aronson is an American psychologist who has carried out experiments on the theory of cognitive dissonance, and invented the Jigsaw Classroom, a cooperative teaching technique which facilitates learning while reducing interethnic hostility and prejudice. In his 1972 social psychology textbook, The Social Animal, he stated Aronson's First Law: "People who do crazy things are not necessarily crazy," thus asserting the importance of situational factors in bizarre behavior. He is the only person in the 120-year history of the American Psychological Association to have won all three of its major awards: for writing, for teaching, and for research. In 2007 he received the William James Award for Lifetime Achievement from the Association for Psychological Science, in which he was cited as the scientist who "fundamentally changed the way we look at everyday life.” A Review of General Psychology survey, published in 2002, ranked Aronson as the 78th most cited psychologist of the 20th century. He officially retired in 1994 but continues to teach and write.
Apophenia is the tendency to perceive meaningful connections between unrelated things. The term was coined by psychiatrist Klaus Conrad in his 1958 publication on the beginning stages of schizophrenia. He defined it as "unmotivated seeing of connections [accompanied by] a specific feeling of abnormal meaningfulness". He described the early stages of delusional thought as self-referential over-interpretations of actual sensory perceptions, as opposed to hallucinations.
Rationalization is a defense mechanism in which apparent logical reasons are given to justify behavior that is motivated by unconscious instinctual impulses. It is an attempt to find reasons for behaviors, especially one's own. Rationalizations are used to defend against feelings of guilt, maintain self-respect, and protect oneself from criticism.
The Courage to Heal: A Guide for Women Survivors of Child Sexual Abuse is a self-help book by poet Ellen Bass and Laura Davis that focuses on recovery from child sexual abuse and has been called "controversial and polarizing".
Carol Anne Tavris is an American social psychologist and feminist. She has devoted her career to writing and lecturing about the contributions of psychological science to the beliefs and practices that guide people's lives, and to criticizing "psychobabble," "biobunk," and pseudoscience. Her many writings have dealt with critical thinking, cognitive dissonance, anger, gender, and other topics in psychology.
The False Memory Syndrome Foundation (FMSF) was a nonprofit organization founded in 1992 and dissolved in late 2019.
The Skeptic Encyclopedia of Pseudoscience is a two-volume collection of articles that discuss the Skeptics Society's scientific findings of investigations into pseudoscientific and supernatural claims. The editor, Michael Shermer, director of the Skeptics Society, has compiled articles originally published in Skeptic magazine with some conceptual overviews and historical documents to create this encyclopedia. It was published by ABC-CLIO in 2002.
A false allegation of child sexual abuse is an accusation against one or more individuals claiming that they committed child sexual abuse when no abuse has been committed by the accused. Such accusations can be brought by the alleged victim, or by another person on the alleged victim’s behalf. Studies on the rate of recorded child abuse allegations in the 1990s suggested that the overall rate of false accusations at that time was approximately 10%.
Self-justification describes how, when a person encounters cognitive dissonance, or a situation in which a person's behavior is inconsistent with their beliefs (hypocrisy), that person tends to justify the behavior and deny any negative feedback associated with the behavior.
The introspection illusion is a cognitive bias in which people wrongly think they have direct insight into the origins of their mental states, while treating others' introspections as unreliable. The illusion has been examined in psychological experiments, and suggested as a basis for biases in how people compare themselves to others. These experiments have been interpreted as suggesting that, rather than offering direct access to the processes underlying mental states, introspection is a process of construction and inference, much as people indirectly infer others' mental states from their behaviour.
Wronger than wrong is a statement that equates two errors when one of the errors is clearly more wrong than the other. It was described by Michael Shermer as Asimov's axiom. The mistake was discussed in Isaac Asimov's book of essays The Relativity of Wrong as well as in a 1989 article of the same name in the Fall 1989 issue of the Skeptical Inquirer:
When people thought the Earth was flat, they were wrong. When people thought the Earth was spherical, they were wrong. But if you think that thinking the Earth is spherical is just as wrong as thinking the Earth is flat, then your view is wronger than both of them put together.
The uniqueness thesis is “the idea that a body of evidence justifies at most one proposition out of a competing set of propositions and that it justifies at most one attitude toward any particular proposition.” The types of attitudes towards a proposition, are: believing, disbelieving, and suspending judgment. The uniqueness thesis claims that, given a body of evidence, one of these attitudes is the rationally justified one. The justification referred to in this thesis is epistemic justification.
