Nothing divides the professional and
academic community who work in the field of sexual abuse quite like the
polygraph. It is a debate that has gone on internationally for decades. A
fascinating wrinkle in policy and the law recently came to the authors’
attention. In at least one state in the USA, there is a policy holding that
people on probation cannot be sent back to prison for failing a polygraph
examination; which makes sense given the status of the research around the
polygraph and its admissibility in court. However, in this state, the same
people can be sent back to prison if the examiner believes they have
deliberately manipulated the results of the test. This has resulted in at least
one examiner expressing certainty that many of his examinees have tried to
influence the results, with many of them becoming incarcerated because of the
examiner’s belief. Which highlights the main issue that the polygraph faces, that
there are a multitude of different audiences (public, judiciary, professionals,
academics, etc) all with different attitudes, experiences, evidence bases and
strongly held views around it.
We want to be clear that this is more a
problem of how professionals use or even abuse the power that they have over
clients/examinees than it is about the polygraph itself, although empirically
separating the effects of the polygraph from the examiner may be more
complicated than many would think. The good news is that the Department of Corrections
in that state is having a fresh look at its policies. The bad news is the
context of professionals believing in their approach to the detriment of their
clients. In some cases, one wonders how much deception by the examiner in the
process is acceptable given the potential costs and lack of truly informed
consent. These kinds of ethical questions certainly exist elsewhere,
but rarely get the attention they deserve with vulnerable populations such as
those for whom basic liberties are in the balance.
To put all of this into perspective, it
can be useful to review what research has shown time and again: Punishment on
its own neither reduces risk nor deters crime. While many questions about
treatment remain debatable, people who complete treatment programs emerge at
lower risk. Community supervision can also further reduce risk, and yet there
is still no credible evidence that the polygraph, as currently applied, is
improving outcomes, except in the opinions of its adherents.
This, in turn leads to further questions.
When we apply the polygraph as described above, with examiners being able to
send people to prison so easily, at what point are we not only interfering with
methods that would promote community safety, but also denying justice? (as a
side note, it is important to note that others in our field, including
therapists, can also wield undue negative influence under the wrong conditions).
We then need to turn to other questions,
such as what our goals actually are? Are we using the available methods to
reduce risk? Build better lives? Assist those who have been abused? Or continue
the punishment? Our belief is that punishment is punishment and rehabilitation
is rehabilitation, and that when we confuse the two, neither can be entirely
effective.
Finally, there is a real question of the
polygraph’s best use. Does a sexual history polygraph really provide as much
information as one might hope or is an examination into whether someone is
basically following the rules help them – and the community – more. Do other
methods, such as polygraphing people on their thoughts and fantasies simply
muddy the waters through a belief that one’s fantasies equals their future
behavior”?
Additionally, we would also encourage a
consideration of how the polygraph is used internationally. While the polygraph
is not necessarily an example of American exceptionalism, it might as well be
because most other countries internationally do not use the polygraph in the
same way, with the same frequency or with it having the same impact in the
criminal justice system as in the USA. For example, in the UK the polygraph was
only introduced in 2014 for
high risk individuals, it is by no means used with all people that have
committed a sexual offence, and is not admissible in court. Whereas in other
countries, like Australia, Israel, Sweden and New Zealand (to name a few) the
polygraph is not used with individuals that have committed a sexual offence.
Unfortunately, recent dialog has focused
more on choosing sides – for and against the polygraph – than sorting through
the various issues and balancing them against the human rights of each client
or examinee. We must keep in mind, in our desire to discover the truth and seek
answers from those that commit sexual abuse, that the consequences of false
positive (as well as the resulting conviction and related outcomes) can be
significant for victims and the accused.
Perhaps before we can answer questions
about the polygraph, it is better that we return to the basic questions of why
we do this work and what all our science tells us about the way people become
safer and grow beyond their traumatic experiences.
