In Journal ASA, March 1979, a communication by Ronald L. Koteskey
exhorted Christian
psychologists to abandon the use of deception in their psychological research.
Although Koteskey's conclusion that deception is lying, and therefore
unacceptable,
cannot be faulted on theological grounds, I believe that his characterization
of the use of deception is, at times, inaccurate. This paper is an attempt to
clarify several important points that Koteskey either omitted or, in
my opinion,
misperceived.
1. Koteskey never formally presents the rationale behind the use of deception
in social psychological research. Deception is basically used to more closely
approximate a "real world" situation. Koteskey implies just
the opposite:
that deception creates artificiality, suspicion and bias. Most social
psychologists
would submit that deception is, in many cases, a good "real
world" approximation.
Just as the subjects are unaware of the experimenters motives, we are
often unaware
of the motives of the persons around us with whom we are interacting.
2. Koteskey characterizes the social psychologist as a devious individual who
sits in his laboratory constantly developing techniques to be used in
duping unsuspecting
subjects. Nothing could be further from the truth. The conscientious
social psychologist
uses deception only as a last resort when, in his/her opinion, the phenomenon
cannot be with subjects who are aware of the experimental hypothesis. In fact,
one of the most highly respected
textbooks on research methods in social psychology (Carismith, Ellsworth, and
Aronson, 1976) suggests that the experimenter confronted with the
choice between
deception and a less preferable method, should probably elect to
utilize the latter,
provided it is still adequate.
3. Koteskey's emphasis on the data that show up to an 803/4 deception rate in
certain areas of social psychological research was an accurate account of the
state of affairs in the '60's. 1 would be reluctant to generalize the
same finding
to the present. Over the last ten years psychologists have become increasingly
sensitive to the rights of human research participants. As evidence
of this, the
American Psychological Association published a number of guidelines
in 1973 regarding
the ethical principles to be upheld when conducting research with
human participants.
While deception is an acceptable technique within these guidelines,
the increased
emphasis on ethical considerations is certainly a step in the right direction.
Another point that I believe potentially outdates Koteskey's
implication of increasingly
deceptive research, is the changing nature of social psychology as a discipline
over the past 10-12 years. The increasing emphasis on rational information
processing
in social psychology has often eliminated the need for deception.
4. While Koteskey's article is fundamentally correct with respect to
the finding
that subjects approach the experiment with suspicion, he leaves the reader with
indomplete information about the nature of the suspicion. Koteskey allows the
reader to conclude that a subject's behavior is systematically
altered by suspicion.
Unfortunately, there is very little data upon which to make such a
firm judgment.
For behavior to be systematically altered, subjects would (in most experiments)
have to guess the experimenters hypothesis correctly. This is a highly unlikely
occurrence. A more tenable explanation is put forth by Kelman (1968)
and Carlsmith,
Ellsworth, and Aronson (1976). They suggest that the subjects' suspicion could
be classified as generalized suspicion. While this viewpoint acknowledges the
suspiciousness of subjects, it does not suggest that there are
necessarily systematic
biases in the data. Rather, it suggests that suspicion increases the subjects'
"trying to guess the hypothesis" behavior. However, since
it is untenable
to believe that all of the subjects are correctly guessing the hypothesis, it
is assumed that many hypotheses are generated. As a result, we do not
get systematic
biases, but rather we get an increase in our error variance.
Therefore, the literature
of social psychology is not filled with artifactual data due to
subject suspicion,
but rather we have probably failed to reject the null hypothesis when
it was untenable,
i.e., we may have missed effects that really exist. This admittedly forces us
into a very conservative framework, but it also seems to present a
more accurate
picture of social psychological research than the one implied by Kuteskey.
I would like to briefly relate my own experience with subject
suspicion in research.
Most of my research involves having subjects fill out
post-experimental questionnaires
or have a verbal interview to assess suspicion. Subjects in my research often
express suspicion, but it tends to be of a generalized nature, i.e., they often
believe that there is something going on that is not obvious. However, rarely
can they be very specific about it. Furthermore, comparisons between those who
express suspicion and those who do not, has never revealed
significant differences.
5.I take exception with Koteskey's comment that deception in
research can never
lead to truth. I submit that the truth as he describes it, is
different from the
truth that psychologists are seeking. There can essentially be two
ways of looking
at the term truth: subjectively and objectively. Hindus, Moslems, and
Christians
all claim to be seeking and attaining truth, but we find little similarity in
their methods utilized to obtain the ''ultimate'' or even in what the
"ultimate"
is. They are, in a sense, looking at truth subjectively. Psychologists, on she
other hand, attempt to deal with truth objectively, as do other
scientists. That
is, we are looking for lawful relationships just as the chemist or
medical research
looks for lawful relationships. Unlike the religions mentioned earlier, truth
to the psychologist (as an ultimate goal) refers to indisputable,
objective data.
An example should suffice to illustrate my point. Often in medical
research, placebo
groups are included. These people receive an injection or pill, but
are not informed
about the innocuous nature of the treatment. They are being deceived. Does this
automatically doom the results of this research? Would we say that
the data collected
in this research were not the truth? We would probably be unlikely to make such
a judgment. Why then, does Koteskey reason that deception in
psychological experiments
yields untruth. I can conclude only that he is referring to subjective truth,
since the use of deception is obviously not within his own personal
framework.
6. Finally, Koteskey seems to ally himself with the notion that
simulations, naturalistic
observations, and unobtrusive measures are preferable to the use of deception.
Unfortunately, he fails to consider the possible ethical
considerations involved
in using some of these techniques. For example, research in the field where we
might use naturalistic observation, often denies the subjects the right to give
their informed consent. Since these persons are unknowingly
participating in research,
they are in a sense being deceived. While this can be ethical within
the framework
set up by the American Psychological Association, it obviously is inconsistent
with Koteskey's expressed viewpoint.
In summary, I am not advocating that Christian psychologists adopt deception as
a means of doing research. That is a decision that individual
psychologists must
struggle with. I do agree with Koteskey's statement that methods of
research and
testing must be improved. However, to totally dismiss the findings of research
because deception was used is, I believe, an inaccurate formulation.
