Using lie detector test to win an argument is an Auto-BOBO
Polygraph
or Lie Detector Test is not a test, it’s an intense interrogation, and the only
part that polygraph plays is to frighten or intimidate a person into making a confession
or an admission.
It
doesn’t record truth or deception, there is no such thing as “lying reaction” it records nervousness.
The
reaction that would brand a person as a liar only indicates deception about
fifty percent (50%) of the time.
What
the polygraph records are your blood pressure, pulse rate and it also shows the
galvanic skin response that’s where the electrodes are placed on the first and
third fingers of your right hand and it records the sweat activity.
In
the Philippines, netizens are more confident to brand lie detector tests as
proof to win an argument or dispute like in Raffy Tulfo Action, a segment in
TV5.
Atty.
Ranny Randolf B. Libayan of Libayan
& Associates-BATASnatin The Firm discussed the
inadmissibility of lie detector test in Philippine Law and why Raffy Tulfo
commenters are fond to brand polygraph test as evidence.
Atty.
Libayan said, “Sa comment section dapat
wag tayong auto-bobo. Isa sa mga auto-bobo na comment ay kapag meron tayong
nakita na nag-sasabi ng mga declaration or salaysay nila, eh mag-cocoment tayo
na ela-lie detector test yan.”
In
the said case, the Supreme Court said that polygraph is an electromechanical
instrument that simultaneously measures and records certain physiological
changes in the human body that are believed to be involuntarily caused by an
examinee’s conscious attempt to deceive the questioner.
The
theory behind a polygraph or lie detector test is that a person who lies
deliberately will have rising blood pressure and a subconscious block in
breathing, which will be recorded on the graph.
However,
American courts almost uniformly reject the results of polygraphs tests when
offered in evidence to establish the guilt or innocence of one accused of a
crime, whether the accused or the prosecution seeks its introduction, for the
reason that polygraph hasNOTas yet attained scientific acceptance as a
reliable and ascertaining truth or deception.
“Ang polygraph test ay hindi
admissible sa korte at kahit mag-polygraph test ka, walang silbi ito at hindi
ito paniniwalaan. Kung hindi ito pinapaniwalaan ng korte, dapat hindi nyo rin
paniwalaan,” Atty Libayan added.
