Over the years, the Los Angeles Police Department has received
numerous offers of assistance from psychics and others claiming to
have extrasensory perception. |
Along with these offers are numerous reports in the media that
psychics have provided information useful in major police
investigations. |
K/R: Many media reports have stated that police
departments have made widespread use of psychics in major
crime investigations and have also described impressive
successes resulting from their collaboration with police. |
A couple of years ago, I began an investigation to find out if the
department does, in fact, employ or use psychics and, if so, if they
have been helpful in the investigation of crimes. |
It turned out that the department had done two little-known studies to
test the claims of some psychics. Both studies concluded that the use
of psychics in the investigation of major crimes is unlikely to
produce much useful information. |
K/R: Extending the results of these studies would indicate
that the use of psychics in the investigation of major crimes is unlikely
to produce investigatively useful information. |
Initially, I was referred to a 1980 police study concerning the use of
psychics by Martin Reiser, director of Behavioral Sciences Services
for the Los Angeles police, Susan Saxe, police staff psychologist, and
Detective Philip Sartuche, Robbery-Homicide Division. |
Their report stated: "Contrary to some statements, the LAPD has not
employed psychics in criminal investigations. The same situation
appears to be true for most police departments contacted. In several
well-publicized major cases where individuals who claimed psychic
powers volunteered information to the department about the crime, the
information has not proven useful to the investigation. Similarly, a
comprehensive analysis of psychic claims in solving major crimes by
C. E. M. Hansel in 'ESP: A Scientific Evaluation,' revealed little
correspondence between media reports and later objective
documentation." |
K/R: [Quote is essentially accurate (apart from a stylistic
change to the Hansel citation); authors Klyver and Reiser acknowledge
Sartuche and Saxe on the first page.] |
In 1979, the Los Angeles police decided to design a study to
investigate the feasibility of using psychics' information to aid in
the identification and apprehension of suspects in major crime cases. |
R: In the interest of possible increased effectiveness,
and the saving of time, manpower, and funds, it was decided to design
a research study to investigate the feasibility of utilizing psychic
information to aid in the identification and apprehension of suspects
in major crime cases. |
Twelve psychics participated in the
project. Eight were considered to be professional
psychics; four were considered non-professionals. |
R: Twelve psychics participated in this
project. Eight of the group are considered to be
professional psychics as they either partially or wholly earn
their living by means of fees for their psychic services.
Four of the group are considered nonprofessional
psychics. |
The participants were selected by D. Louise Ludwig,
then-associate professor of psychology at Los Angeles City College,
from those considered to be the most reputable and able in the Los
Angeles area who were willing to participate. |
R: The participants were selected by the second author, an
academic psychologist, from among those considered to be the most
reputable and able in the Los Angeles area who were willing to
participate. |
Four crimes, two solved and two unsolved, were selected by
an investigator not involved in the research. No information about the
crimes was given to the project staff or to the academic
consultant. |
R: Four crimes, two solved and two unsolved, were
selected by an investigator not involved in the research. No
information about the crimes was given to the project staff or to the
academic consultant. |
Of the unsolved cases, one contained a detailed
description of the suspect and the crime itself; no suspect
information was available in the other. Physical evidence from each of
the four crimes was placed in sealed, numbered envelopes. Each
psychic was interviewed individually and first asked
to elicit information from the sealed envelopes. Responses were
tape-recorded. Then the psychic was asked to open each envelope,
look and [sic] and examine the evidence, and again react to
the unconcealed evidence. These responses were also recorded
verbatim. |

Neither the psychics nor the psychologist-experimenter had
any prior knowledge of any of the cases or evidence. This prevented
the experimenter from unconsciously influencing the participants. |
R: Neither the participants (psychics)
nor the psychologist-experimenter had any prior knowledge of any
of the cases or the evidence. This prevented the experimenter from
unconsciously "sending" or influencing the participants
in a prejudged way. |
Data was grouped into the following categories, which
corresponded with the information recorded on the original crime
reports: the crime committed, victims, suspects, physical descriptions
and crime locations. Other information elicited from the participants,
which could not in any case be verified, included accessories to the
crime, life style of the victim and/or suspect, and psychological
traits of the victim and/or suspect. |
R: Data was grouped into the following categories,
which corresponded with the information recorded in the
original crime reports: crime(s) committed,
victim(s), suspect(s), physical
description(s), and crime
location(s). Other information elicited from the
participants, but which could not in each case be
verified, included accessories to the crime, lifestyle of the victim
and/or suspect, and psychological traits of the victim and/or
suspect. |
However, as only 50% of the information provided by the
psychics was verifiable, the study focused only on verifiable
criteria indicators. |
R: However, as only approximately 50 percent of
the information provided by the psychics was verifiable, the study
focused on these verifiable criteria indicators. |
In many instances, the psychics did not comment on all
categories, and often they did not specify in which category specific
information applied. Further, some of the participants were extremely
verbose, while others provided only very sketchy responses. |

The Los Angeles Police Department conclusion: The research
data does not support the contention that psychics can provide
significant additional information leading to the solution of major
crimes. |
R: The research data does not support the contention that
psychics can provide significant additional information leading to the
solution of major crimes. |
The area of greatest accuracy had to do with the sex of
the suspect and sex of the victim. Some degree of accuracy was also
detected in the type of crime committed. |
R: The area of greatest accuracy had to do with the sex of
the suspect and sex of the victim. Some degree of accuracy was also
detected in the type of crime committed. |
A common thread ran through many of the psychics'
responses. The most commonly repeated conception of these crimes was
that the victim was a female prostitute murdered by a male, with drug
involvement either by the victim, the suspect or both. |

Many of the psychics believed these cases might have
been connected with the "Hillside Strangler," a highly publicized case
in the news at the time this study was conducted. However, none of the
crimes involved in the study were related to that case. |

Overall, little, if any, information was elicited from
the 12 participants that would provide material helpful in the
investigation of the major crimes in question. |

"We are forced to conclude, based on our results, that the
usefulness of psychics as an aid in criminal investigation has not
been validated," the report stated. |
R: [Quote is accurate.] |
Because of the continuing controversy about the
usefulness of psychics in crime investigations, the department
decided to do a further study. That was done in 1980. |
K/R: Because of the continuing controversy about the
usefulness of psychics in crime investigations, it was desirable
to attempt a replication of Reiser's (1979) study. |
It used two additional comparison groups that
could provide empirical reference points. The use of control
groups would also help clarify whether individuals not identified as
psychic could produce useful information. |
K/R: Since there was difficulty in assigning clearly
derived probabilities to the data produced by the psychics in the
previous (1979) study, in the present study it was decided to
utilize two additional comparison groups which could
provide empirical reference points. The use of control groups would
also help clarify whether individuals not identified as psychic
can produce investigatively useful data. |
Two teams of psychics, four in one group and
eight in the other, participated in the study. In addition, two
comparison groups were used. The first such control
group consisted of 12 homicide detectives who volunteered to
participate in the study. The second group consisted of
11 volunteers who were representative of the general student
population. The two non-psychic groups were instructed to take each
piece of evidence and attempt to guess the characteristics of
both the victim and suspect in each crime. |
K/R: Two teams of "sensitives" (identified by
non-LAPD psychologists), four in one group and eight in the other,
participated in the study. In addition, two comparison (control)
groups were used. The first group consisted of eleven
college student volunteers who were representative of the general
student population. The second comparison group was
composed of twelve homicide detectives who volunteered to
participate in the project. [...] The two non-psychic groups
were instructed to take each piece of evidence and attempt to
intuit or guess characteristics of both the victim and suspect in
each crime. |
The data produced by the three groups differed markedly in
character and quantity. |
K/R: The data produced by the three groups differed markedly
in character and in quantity. |
Most of the psychics generated lengthy discourses with
dramatic and confident-sounding statements. Their accounts were also
characterized by many direct-perception statements, like "I now see
such-and-such." |
K/R: Most of the psychics generated lengthy
discourses with dramatic and confident-sounding statements. Their
accounts were also characterized by many direct perception
statements of the form "I now see such and such." |
In contrast to the psychics' statements, those
the detective group produced were very terse and highly
qualified. The detectives clearly felt uncomfortable with the
instructions to rely on intuition and feelings. |

detective group produced very terse and highly qualified
statements. They clearly felt uncomfortable with the
instruction set which asked them to rely on intuition and
feelings. |
The students appeared to feel slightly more at
ease with the task than did the detectives. Their statements tended to
be lists of information without any of the dramatic and
ostensibly sensory descriptions that characterized the psychics'
data. |

[...] Their statements tended to be lists of information without
any of the dramatic and apparently sensory-derived
descriptions that characterized the psychics' data. |
The study concluded: "Since the psychic group produced
approximately 10 times as much information as either of the two
comparison groups, it is more likely by chance alone that their data
would produce more 'hits.' Despite this statistical advantage, the
psychics were unable to produce information that was significantly
better than the two comparison groups. It is important to note that no
information that would have been investigatively useful, such as first
and last names, license plate numbers, apartment house locations,
etc., was accurately produced by any of the subjects. Statistically,
the data fit a pattern that could be expected by chance." |
K/R: [Quote is accurate, apart from "10" for "ten,"
unindicated ellipses before sentence beginning "It is important to
note" and before the final sentence, where a single sentence
parenthetical statement referencing a table of data has been deleted
in each case, and removed italicization on the word "any" in the
penultimate sentence.] |
The study added: "The data provided no support for the
belief that the identified 'sensitives' could produce investigatively
useful information. Additionally, the data also failed to show that
the psychics could produce any information relating to the cases
beyond a chance level of expectancy." |
K/R: [Quote is accurate, apart from removal of italicization
on "any" in the last sentence.] |
Evidence from this study was consistent
with, and replicated, the findings of the Los
Angeles Police Department's earlier study. |

Extending the results of these studies would indicate that
the use of psychics in the investigation of major crimes is unlikely
to produce much useful information. |

Has the Los Angeles Police Department changed its policy or
views regarding the use of psychics in the last seven years? |
No, according to Dan Cooke, head of public relations for
the department. "The LAPD has not, does not and will not use psychics
in the investigation of crimes, period," Cooke said. "If a psychic
offers free information to us over the phone, we will listen to them
politely, but we do not take them seriously. It is a waste of time." |
