To assess the claims of psychic crime-solving, the Committee for the Scientific Investigation of Claims of the Paranormal (now Committee for Skeptical Inquiry) established a task force of investigators. The group recorded many failures by psychics to provide useful information to criminal investigators, and felt that psychics may use "retrofitting" (or after-the-fact matching), offering vague clues, and then trying to retroactively fit them to details that are only discovered later. In addition to cases of retrofitting, the apparent use of cold reading (a psychic's fishing for information while appearing to gain it paranormally), exaggeration, and examples where the psychic has used non-psychic sources of information, were also reviewed.
