Although it can be argued that all legal problems
in all branches of the law are psychology-dependent only Criminal
law actively uses psychology Modern Legal Psychology still remains
mainly a Psychology of Criminal law. It is only recently that psychology
has been taken up in some areas of Civil law. This narrow focus
of psychological impact on the consideration of crimes and criminals
leaves vast areas of the law untouched by psychology and psychologists.
Yet Criminal law is not even regarded by many as a leading branch
of the Law. It cannot be seen as more important or more used than
such aspects as constitutional, international, administrative,
ecological, business, labour or any other laws.
National law systems around the world seem to be very different
in the degree to which they use psychology. Some use it only
exceptionally, yet for others
psychological input is much more commonplace. For example, in Lithuania psychological
examination is not used to assess a defendant’s ability to understand the
police caution, to cooperate with a lawyer or to follow trial proceedings, nor
is psychological expertise not used to assess the impact of emotional distress,
or a person’s competence to handle his/her finances, etc. All this is routine
in USA or Germany.
Yet it is interesting to note that all national
legal systems seem to embrace psychology in a similar sequence,
almost as if there were a natural psychological
development to the incorporation of psychological concepts and methods. It
would seem the starting point is the consideration of children
as witnesses in criminal
proceedings. This is then expanded to consider the capabilities of various
sub-groups of adults to cope with the court processes. These capacities
are further broadened
to evaluate the impact of various emotional and other mental states on the
fitness to plead or to offer evidence.
Beyond these examinations of individuals in the
context of crimes slow steps are taken to consider similar issues
in areas of civil law, most notably family
court cases. In rare situations the potential contribution of psychology
is explored in relation to broader matters such as legal codification,
classification,
and
interpretation of human actions.
Two sets of factors seem to be of
special importance in determining the progress towards using psychology
in a national legal system.
The first is how the
differences between the epistemologies of law and psychology are resolved.
The law is normative
and psychology is a science. The law operates with dichotomous certainties
and psychology with arrays of probabilities. So, that even though adversarial
judicial
systems search for truth in different ways from magisterial ones, they both
seek a definitive truth that contrasts with the unfolding dialectic that
is the essence
of scientific psychology.
The second set of factors that impact on the
uptake of psychology by the law is external to both psychology
and law. They are the speed of influence
of
current global social changes within any given society. As we have seen
with the demise
of totalitarian systems around the world, the speed of democratization,
and improvement of human rights brings with it a hunger for the
systematic, scientific
resolution
of many legal problems that psychologists are well placed to assuage. I
would even go so far as to say that positive developments in a
modern society require
and generate an increasing “psychologization” of its Law.
To further this productive process it would be
valuable to map out the opportunities for psychological contributions
to legal systems far beyond
eye witness testimony
and the fitness of defendants to plead, into realms beyond courts of
criminal justice. Such a map is both geographical and conceptual.
It would, for
example, be of enormous value to have a clear account of exactly how
psychological expertise is used in the legal systems of different
countries. This would
reveal what
is common to many countries and where there are particular, rare nuggets
of activity
from which others can learn. From this it may be possible to develop
an overview
that might have some analogy to the famous Mendeleyev periodic table
that has proved so valuable in Chemistry. This could present the
main areas
of legislation,
implementation and application (in rows) in every branch of the Law (columns).
Each cell of such a table could further indicate the degree to which
psychology is used for those matters in that area of jurisprudence.
Such a “Periodic table for Legal Psychology” would expose extensive
virgin territory of the law into which psychology could penetrate and thus give
impetus and focus to research for this important branch of psychology.
