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, and 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 is insuperable for most people, but they can manage it, for example, by education and training in critical thinking skills.
A heuristic, or heuristic technique, is any approach to problem solving that employs a practical method that is not fully optimized, perfected, or rationalized, but is nevertheless sufficient for reaching an immediate, short-term goal or approximation. Where finding an optimal solution is impossible or impractical, heuristic methods can be used to speed up the process of finding a satisfactory solution. Heuristics can be mental shortcuts that ease the cognitive load of making a decision.
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 an action or idea is psychologically inconsistent with the other, people do all in their power to change either so that 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.
The availability heuristic, also known as availability bias, is a mental shortcut that relies on immediate examples that come to a given person's mind when evaluating a specific topic, concept, method, or decision. This heuristic, operating on the notion that, if something can be recalled, it must be important, or at least more important than alternative solutions not as readily recalled, is inherently biased toward recently acquired information.
Hindsight bias, also known as the knew-it-all-along phenomenon or creeping determinism, is the common tendency for people to perceive past events as having been more predictable than they were.
The anchoring effect is a psychological phenomenon in which an individual's judgements or decisions are influenced by a reference point or "anchor" which can be completely irrelevant. Both numeric and non-numeric anchoring have been reported in research. In numeric anchoring, once the value of the anchor is set, subsequent arguments, estimates, etc. made by an individual may change from what they would have otherwise been without the anchor. For example, an individual may be more likely to purchase a car if it is placed alongside a more expensive model. Prices discussed in negotiations that are lower than the anchor may seem reasonable, perhaps even cheap to the buyer, even if said prices are still relatively higher than the actual market value of the car. Another example may be when estimating the orbit of Mars, one might start with the Earth's orbit and then adjust upward until they reach a value that seems reasonable.
A miscarriage of justice occurs when an unfair outcome occurs in a criminal or civil proceeding, such as the conviction and punishment of a person for a crime they did not commit. Miscarriages are also known as wrongful convictions. Innocent people have sometimes ended up in prison for years before their conviction has eventually been overturned. They may be exonerated if new evidence comes to light or it is determined that the police or prosecutor committed some kind of misconduct at the original trial. In some jurisdictions this leads to the payment of compensation.
A false confession is an admission of guilt for a crime which the individual did not commit. Although such confessions seem counterintuitive, they can be made voluntarily, perhaps to protect a third party, or induced through coercive interrogation techniques. When some degree of coercion is involved, studies have found that subjects with highly sophisticated intelligence or manipulated by their so-called "friends" are more likely to make such confessions. Young people are particularly vulnerable to confessing, especially when stressed, tired, or traumatized, and have a significantly higher rate of false confessions than adults. Hundreds of innocent people have been convicted, imprisoned, and sometimes sentenced to death after confessing to crimes they did not commit—but years later, have been exonerated. It was not until several shocking false confession cases were publicized in the late 1980s, combined with the introduction of DNA evidence, that the extent of wrongful convictions began to emerge—and how often false confessions played a role in these.
Salience is that property by which some thing stands out. Salient events are an attentional mechanism by which organisms learn and survive; those organisms can focus their limited perceptual and cognitive resources on the pertinent subset of the sensory data available to them.
Selective exposure is a theory within the practice of psychology, often used in media and communication research, that historically refers to individuals' tendency to favorite information which reinforces their pre-existing views while avoiding contradictory information. Selective exposure has also been known and defined as "congeniality bias" or "confirmation bias" in various texts throughout the years.

Eyewitness testimony is the account a bystander or victim gives in the courtroom, describing what that person observed that occurred during the specific incident under investigation. Ideally this recollection of events is detailed; however, this is not always the case. This recollection is used as evidence to show what happened from a witness' point of view. Memory recall has been considered a credible source in the past, but has recently come under attack as forensics can now support psychologists in their claim that memories and individual perceptions can be unreliable, manipulated, and biased. As a result of this, many countries, and states within the United States, are now attempting to make changes in how eyewitness testimony is presented in court. Eyewitness testimony is a specialized focus within cognitive psychology.
Eyewitness memory is a person's episodic memory for a crime or other witnessed dramatic event. Eyewitness testimony is often relied upon in the judicial system. It can also refer to an individual's memory for a face, where they are required to remember the face of their perpetrator, for example. However, the accuracy of eyewitness memories is sometimes questioned because there are many factors that can act during encoding and retrieval of the witnessed event which may adversely affect the creation and maintenance of the memory for the event. Experts have found evidence to suggest that eyewitness memory is fallible.
Cognitive bias mitigation is the prevention and reduction of the negative effects of cognitive biases – unconscious, automatic influences on human judgment and decision making that reliably produce reasoning errors.
Authority bias is the tendency to attribute greater accuracy to the opinion of an authority figure and be more influenced by that opinion. An individual is more influenced by the opinion of this authority figure, believing their views to be more credible, and hence place greater emphasis on the authority figure's viewpoint and are more likely to obey them. This concept is considered one of the social cognitive biases or collective cognitive biases.
A presumption of guilt is any presumption within the criminal justice system that a person is guilty of a crime, for example a presumption that a suspect is guilty unless or until proven to be innocent. Such a presumption may legitimately arise from a rule of law or a procedural rule of the court or other adjudicating body which determines how the facts in the case are to be proved, and may be either rebuttable or irrebuttable. An irrebuttable presumption of fact may not be challenged by the defense, and the presumed fact is taken as having been proved. A rebuttable presumption shifts the burden of proof onto the defense, who must collect and present evidence to prove the suspect's innocence, in order to obtain acquittal.
Political cognition refers to the study of how individuals come to understand the political world, and how this understanding leads to political behavior. Some of the processes studied under the umbrella of political cognition include attention, interpretation, judgment, and memory. Most of the advancements in the area have been made by scholars in the fields of social psychology, political science, and communication studies.
Investigative interviewing is a non-coercive method for questioning victims, witnesses and suspects of crimes. Generally, investigative interviewing "involves eliciting a detailed and accurate account of an event or situation from a person to assist decision-making". This interviewing technique is ethical and research based, and it stimulates safe and effective gathering of evidence. The goal of an investigative interview is to obtain accurate, reliable and actionable information. The method aims at maximising the likelihood of obtaining relevant information and minimise the risks of contaminating evidence obtained in police questioning. The method has been described as a tool for mitigating the use of torture, coercion and psychological manipulation, and for averting forced confessions and errors of justice leading to wrongful convictions and miscarriages of justice.
