Psychologists, researchers and other authors have posited a number of possible explanations for the belief that some can provide valuable crime information from psychic abilities. The possible explanations include confirmation bias (or our natural tendency to favor information to confirm our beliefs), wishful thinking (which is the act of making decisions based upon what is appealing rather than reasoned), and "retrofitting" (or retroactively refining the specifics of a prediction after the facts are revealed). The act of reinterpreting vague and nebulous statements made by psychic detectives is also referred to as the "multiple out". Taking advantage of these cognitive limitations is the practice of cold reading which creates the illusion of knowing specific information. Additionally, police detectives and other authors suggest that psychic detectives appear successful due to making common-sense or high-probability predictions such as finding bodies at dump sites or "near water."
