2. Those questions should be
--Yes or No answerable
--3 to 17 words each question works best
--Don't use softwords like 'sleep with' if you mean sex

How it
 How a polygraph test works works!

A polygraph test measures microscopic changes at four points
of the body as a series of Yes or No questions is answered.

A client can usually write up to 4 questions to be used for the test.

Questions should be 3 to 15 words long each, with no 'ands', no 'ors', no 'commas'.

Nervousness does not affect test results.

After the questions are developed and discussed, and testing explained,
the examinee is 'polygraphed' (arm squeezed with a blood-pressure cuff,
sitting still, answering the questions)
for three 5-minute periods.

For transparency and integrity, an examiner should be equipped to allow
the client to quietly monitor the exam as it occurs, by CCTV or other method.

Why trust a polygraph test to a part-timer?

On hot days, an examinee should drink water an hour before testing because:

Dehydration affects
improve accuracy of a Los Angeles lie-detector exam with water polygraph results.

If a person is dehydrated, they may not realize it.
On a hot day, they may have already 'sweated out' more water than they took in.

Moisture-changes at the fingertips while answering questions
is an important measurement during a polygraph examination.
(moisture-changes polygraph moisture at fingers is the green line)

Dehydration greatly reduces this important tracing,
and it could interfere in the accuracy of the results.

A good examiner will spot dehydration, require immediate water intake, then try again in after a wait.
Or there is an alternate EDA/GSR method, but this isn't the place to discuss it.
A rushed or inexperienced examiner will allow the testing without fixing the problem.

Know that this is the
#1 lie that polygraph examiners give as an answer when
you ask this simple question while calling around for prices:

"How long will the actual polygraphing take?"

To cover up their high price-quotes, some polygraph examiners will tell you:
"A polygraph exam will take up to two hours."

 How long does a polygraph test really take? or  Does polygraph take more than an hour? ?

The real truth:
No matter which examiner you go to, the person being polygraphed
will be ON THE POLYGRAPH answering Yes or No
questions for only THREE 5-MINUTE PERIODS.

Most of the rest of the time: is just talk.

Many examiners do not want you to know this.

They feel you will be shocked by their price quote if you knew
that the actual polygraphing (when the arm is being squeezed
by a blood-pressure cuff)
time is actually so short.

Old-style polygraph instruments took a lot longer, having to
continually adjust paper, fix ink problems, and constant writing
notes on the paper. Not needed on modern computer polygraphs.

Most of the rest of this time, the longest part, is the 'talk time'.
This is known as 'The Pre-Test Interview'. Explanations are given,
and it is decided what 3 or 4 questions you want asked.

Good examiners instead have you think about, and write down, your questions
before you come in, and will help you make them perfect when you arrive.

And many of the pre-test interview instructions can also be told by phone.

So: most of this 'pre-test' can be done by
phone at at home before you come in.
It still is part of the exam--
you just spend the half hour of question writing BEFORE you come in.

SECRET: The half-hour or more of thought you put
into the questions you write at home equals a half-hour
or more less time you need to be at the examiner's office,
but it's still an important part of the polygraph exam.

It will take no more than an hour for your relationship polygraph exam

if you write your one-to-four questions down on paper before you come in.

    Many examiners attend a 10-week trade school,

    Remember, the actual polygraph questioning

    QUESTION: How has polygraph become such an accurate truth-detecting tool?

    ANSWER: Thanks to tax-dollar-paid government research of more than 60 years!

    find a polygraph test in Los Angeles  <1986 to 2007         Now>lie-detector test in Los Angeles

    What trickles down to polygraph schools is the research done
    by the polygraph academy operated by the US government.
    It teaches the 12-week polygraph course to dozens of federal agencies all year long.

    From 1951 to 1985, it was known as the 'US Army Polygraph School'.
    In 1986, its name was changed to 'Dod-PI' (Department of Defense Polygraph Institute).
    In 2007, its name was changed to 'DACA' (Defense Academy for Credibility Assessment).
    Since 2010, its name has been 'NCCA' (National Center for Credibility Assessment).

    Your situation benefits from this millions
    of dollars spent on lie-detection research.

Another polygraph secret . . .

Arcadia polygraph

Sometimes the written report is the most important part of the exam.
For many, the results of the test (the report) are what is given
to the court, or is given to the other party in your matter.
Here's why you sometimes need toGlendora polygraph    before choosing an examiner:

The Examiner won't be with you later-- only the written report will be your proof.

Unfortunately, some good examiners write a sad, short report. So even if you
were truthful and passed, that report looks so weak that it doesn't carry any weight.

If the report doesn't impress you, it sure won't impress anyone else.

Ours is a 4-page report free Los Angeles polygraph report that has been used
for many legal matters. Some examiners write only a 1-page report!

NOTE: Some Examiners say "A report is included free",
but what might arrive is a few lines telling Pass or Fail,
with a note telling "A more detailed report is available for $100"!

With us, you get to choose! polygraph reportfree Los Angeles polygraph report   -or-   2.polygraph weekends in Los Angeles

You choose either 1. a free 4-page written report, or 2. watch the exam live!

Old videos about $145 polygraph tests

Most law enforcement agencies pay Examiners less than $200 for applicant tests,
so why do the same Examiners try to charge the public more for shorter tests?

secret that many polygraph examiners don't want you to know:

So-called 'Mobile' polygraph examiners are usually part-timers
who don't work enough to cover the cost of having an office.

They aren't helping you by coming to you-- they have no choice-- they don't really have an office.

Secretly, they work polygraph test San Juan Capistrano out of their trunk.

Or worse, they have polygraph test Oceanside you come to their home.

Some will lie to you about having an office but will give you a fake reason why to do it at your home.
Some will say they have an office, but checking the address you'll see it is NOT really theirs.

Professional polygraph standards and training clearly instruct that testing should NOT be at a residence.

Run if a polygraph examiner has you meet for testing at an office building where the examiner is
just renting office space for a few hours. What this actually reveals it that the examiner only
does a few exams per month and doesn't have a sufficient business to have his/her own office.

Only have testing at an examiner's office
that has the examiner's name on the door.

Sport/Event Polygraph Tests

John's polygraph work on various sports-related
matters has proven to be 100% accurate!

Here are just a few examples:

A famous bicycle racer was accused of using polygraph for bicycle racer banned substances after failing a test. He denied it.
He told media that he would gladly take a polygraph test. It was arranged. John arrived. Then the bicycle racer refused.
Later, that bicycle racer admitted that indeed he had used the banned substances.

Baseball player Jose Canseco polygraph for major basseball team playerbaseball player polygraph admitted that he used steroids.
He named other players that he personally knew who also used steroids. Those players all denied it.
Jose passed John's televised polygraph tests naming those other players. The other players still denied it.
Later, those same other players admitted that they had used steroids.

A fishing tournament polygraph test at fishing contestpolygraph test fishing tournament offered a major prize.
Cash, plus a truck, for the biggest fish polygraph test for Los Angeles sporting event caught during the contest's hours.
One guy easily won. But he failed his polygraph when John asked about violating any contest rules regarding the winning fish. He denied it.
Later, the fisherman's son confessed: they had caught the large fish days earlier out further in the water,
and they kept it preserved, hiding it, then next pretending to catch it during the tournament's hours.

lie-detector steroids competitionThere was an 'all-natural' (no steroid or HGH use)polygraph bodybuilder steroid human growth hormonehuman growth hormone polygraph
bodybuilder contest that offered great benefits to the winner: cash, fame,
and endorsement contracts for all-natural body-improving supplements.
During the polygraph, John detected that the bodybuilder using a 'trick' some attempt to use that is said to mask failing reactions.
The bodybuilder failed when told to stop the countermeasures; he then admitted to having used banned substances.

Have you seen polygraph test Los Angeles weight loss TV shows?

Behind the scenes, we are doing polygraph tests for them to make
sure the contestants are following all rules, including no drugs, etc.

Some 'winners' have been caught by our polygraph tests to have been
using weight-loss help that was not authorized, and then were disqualified.

Some 'losers' were caught to have been sneaking unauthorized food into their diets,
causing less than expected weight loss, interferring with program accuracy.

Sex Offender Polygraph Tests

PSCOT polygraph test Los Angeles


Unlike the newly-made crop of recent 'PCSOT examiners', we have been testing
sexual offenders for nearly 30 years with the primary purpose of protecting the public.

polygraph test for sexual offenderspolygraph PCSOT post conviction

We have tested many court-declared Sexually Violent Predators.
We have tested inside many prisons and inside state mental hospitals.
We have tested for many counties, for the Department of
Mental Health, for scores of therapists, for military JAG lawyers,
for court-appointed attorneys, for Federal Probation,
for the in-custodys of many entities, for Public Defenders, and more.

If you have a failed PCSOT Post-Conviction Sexual Offender Test and need a
truly fair and unbiased independent re-test, we are THE choice, and here's why:

e purposely declined to join the easy-income PCSOT 'club' that
attracted examiners from across the country to come running to California
to get 'on the list' for the 'easy money gold rush' when regular PCSOT testing
sex offender polygraph
became mandatory for registered offenders, so that
you can get a truly neutral & independent re-test
(Do you really think one 'club member' is likely to
ever issue different results than a fellow member?!)

Ask us for a copy of the question guidelines by
the California Sex Offender Management Board.

We are your long-time Containment Model partner.
