Polygraphing & Truth Verification
Why a Polygraph test
Tired
of
stock
losses/crime/theft
and
dishonest
people
in
your
business?
I
truly
belief
that
our
company
can
make
a
difference
to
decrease
theft
in
any
company.
Companies
don’t
realize
that
if
they
don’t
spend
money
to
solve
a
specific
problem,
they
can
potentially
lose
millions
each
year.
Employees
get
away
with
a
lot
and
if
not
properly
managed,
will
result
in
losing
money
unnecessarily.
Polygraph
testing
is
a
very
effective
tool
when
used
in
the
correct
way
by
experts.
Tests
are
used
to
verify
the
truth
and
detect
deceit in individuals.
Polygraph
tests
are
quick
and
efficient
and
can
eliminate
the
need
for
lengthy
investigative
processes.
The
polygraph
test
can
immediately
direct
the
investigator.
It
is
important
to
remember,
however,
that
no
one
is
legally
obliged
to
undergo
a
polygraph
test, but that reluctance to take one can arouse suspicion as to the reasons for declining.
The
Polygraph,
commonly
known
as
a
“lie
detector”
is
a
relatively
new
concept
on
the
South
African
Market.
However,
it
has
already
earned
its
rightful
place
in
first
world
countries.
It
is
gaining
greater
popularity
and recognition every minute of the day.
The
operation
of
the
polygraph
technique
depends
on
a
human
phenomenon
which
was
first
discovered
in
the
1920’s,
and
that
is
the
direct
relation
between
a
physiological
stimulation
–
some
condition
perceived
by
the
mind
–
and
a
physiological
reaction,
a
condition
manifested
by
the
body.
As
an
example,
if
you
recall
an
experience
where
something
frightened
the
wits
out
of
you,
you
may
recall
feeling
a
cold
chill,
a
cold
sweat, or a general quavering of the muscles. These symptoms were caused by the danger you mind perceived.
If
someone
asks
you
a
question
about
some
wrongful
conduct
which
you
have
in
fact
committed,
you
cannot
help
but
remember
what
you
have
done.
If
you
admit
it
you
are
inviting
punishment.
If
you
deny
it,
knowing that you are lying, you risk getting caught. During a polygraph test, the risk is that your body will give you away.
Accuracy
Over
two
hundred
and
fifty
tests
have
been
conducted
by
or
under
the
auspices
of
the
American
Polygraph
Association
in
the
past
seventy
five
years
on
the
accuracy
of
polygraph
testing.
Since
a
polygraph
examination
is
a
very
complex
process,
and
many
different
conditions
and
factors
are
involved
in
this
research,
it
is
difficult
to
draw
from
the
data
a
precise
figure
for
the
accuracy
of
polygraph
testing
in
all
settings.
However,
various
independent
studies
have
concluded
an
accuracy
rate
of
at
least
98%,
if
conducted
by
a
competent
examiner,
for
specific
issue
investigations.
Pre-employment
testing
is
considered
to
be
more
or less just as accurate.
While
the
polygraph
technique
is
not
infallible,
research
clearly
indicates
that
when
administered
by
a
competent
examiner,
the
polygraph
test
is
one
of
the
most
accurate
means
available
to
establish
truth
and
deception.
There are basically two ways to beat a polygraph. Either tell the truth, or don’t do the test.
Tru Polygraph
neither practice nor endorse
Computerized Voice-Stress Analysis, Layered Voice-Stress Analysis and / or Voice-Stress Analysis or by any other name.
Polygraph
testing
should
not
be
confused
with
Voice
Stress
Analysis.
Due
to
the
fact
that
independent
studies
have
yielded
that
it
is
“almost
as
accurate
as
flipping
a
coin”,
Tru
Polygraph
and
its
members
prefer
not to be associated with this type of practice in any form. Voice Stress Analysis is also not being accepted by the CCMA.
Who could make use of the Polygraph?
The potential application of the polygraph is astonishingly far and wide. Virtually anyone can undergo a polygraph examination.

How does it work?
A Misconception about polygraph does exist among certain individuals, which needs to be addressed.
It is important to understand what a polygraph examination entails:
A polygraph instrument will collect physiological data from at least 3 systems in the human body.
A typical polygraph examination will include:
A period referred to as a pre-test
A chart collection phase.
A
test
data
analysis
phase
in
the
pre-test,
the
polygraph
examiner
will
complete
required
paperwork
and
talk
with
the
examinee
about
the
test.
During
this
period,
the
examiner
will
discuss
the
questions
to
be
asked
and
familiarize
the
examinee
with
the
testing
procedure.
During
the
chart
collection
phase,
the
examiner
will
administer
and
collect
a
number
of
polygraph
charts.
Following
this,
the
examiner
will
analyze
the charts and render an opinion as to the truthfulness of the person taking the test.
