00:51.0
Okay, disclaimer lang mga kamates, mga kaibigan.
00:54.0
Hindi naman siguro criminal si Boskong TV na para magsinungaling pa dito sa ano na to.
01:01.0
Alam mo, he's not a professional criminal para matrick ang isang polygraph test.
01:06.0
It's doable pero I don't think in this context ay kailangan niya pang gawin nyo.
01:11.0
Kaso mga kamates, mga kaibigan, nasa Nico The Vid Channel tayo.
01:14.0
So we will have to find out the science of the polygraph test.
01:19.0
And meron po tayong guest speaker ngayon na si Fiscal EJ
01:23.0
who will tell us all about the legalities of this lie detector test.
01:29.0
So bakit polygraph test yung pangalan at hindi lie detector test?
01:33.0
Diba yung official na pangalan niya ay polygraph?
01:36.0
Okay, kasi sinabi, ang poly kasi ibig sabihin yan many.
01:40.0
And yung graph, alam nyo naman kung ano yung graph.
01:42.0
So poly kasi marami siyang mini-measure.
01:46.0
So bago tayo pumunta dun sa maraming mini-measure,
01:49.0
I would just like to make you understand the rationale of a lie detector.
01:55.0
Kunyari, nage-exam ka or tinanong ka ng teacher mo,
01:59.0
Nico David, anong kulay ng bip mo?
02:02.0
Hindi mo alam yung sagot kasi hindi mo naman tinignan kung ano yun.
02:06.0
Siyempre, joke lang yun.
02:08.0
Hindi mo alam yung sagot.
02:09.0
Anong unang mong gagawin?
02:11.0
Yung iba sa atin, mapapakamot ng ulo.
02:14.0
Kaya pag hindi mo alam yung sagot,
02:16.0
ang sasabihin ng tao sayo, kamot ulo.
02:19.0
Yung naging idiomatic expression na yun dito sa ating bansa.
02:23.0
Now, yung pagkakamot mo ng ulo is an indication of stress.
02:28.0
Tumataas yung anxiety level mo kasi hindi mo alam yung sagot during that moment.
02:33.0
So isang stress response ng katawan mo is magkamot ng ulo.
02:41.0
So wala namang problema sa pagkakamot ng ulo pag hindi mo alam yung sagot.
02:46.0
Ang nakakaproblema lang pag lagi ka nagkakamot ng ulo.
02:51.0
Baka may kuto ka na, hindi yun.
02:53.0
Pero there are some people na ganyan yung kanilang stress response.
02:58.0
At sa polygraph test, in theory, yun yung hinahanap niya.
03:02.0
Yung mga stress response mo to certain questions.
03:06.0
Kaya sa polygraph test na maraming tinetest,
03:09.0
ito yung kanilang ginagawa, ito yung minimeture nila.
03:13.0
Usually, in some polygraph test, in my research, mga kamatis, mga kaibigan,
03:18.0
mas marami na silang variables or factors na kinuconsider.
03:22.0
Pero yung Kelakong TV, it seems to me na itong apat na ito
03:26.0
ang kanilang minimeture.
03:27.0
Number one, yung blood pressure.
03:29.0
Number two, yung pulso.
03:31.0
Number three, yung paghinga or respiration.
03:33.0
And number four naman, yung skin contactivity.
03:37.0
In usual polygraph test, ito lagi yung hinahanap.
03:41.0
Kaya siya tinawag na poly because of these factors.
03:44.0
Kunyari, pag galit ka, bumibilis yung tibok ng puso mo
03:51.0
because your blood is pumping, tumataas din yung presyon mo.
03:56.0
And pag naistress ka naman, miski malamig,
04:00.0
pinagpapawisan ka ng malamig.
04:02.0
Yung skin contact sa skin conductivity yun.
04:07.0
And bumibilis din yung paghinga mo.
04:09.0
Parang ka nagpapalpitate kapag ikaw ay naistress.
04:16.0
So, ganun ang ibig sabihin,
04:18.0
ang hinahanap sa mga lie detector test.
04:21.0
Now, there are ways to trick it,
04:23.0
pero mamaya natin pag-uusapan yun.
04:25.0
Yung idea muna dapat,
04:27.0
it is really not called lie detector,
04:29.0
it's called a polygraph test
04:31.0
because it is looking for all of these factors.
04:35.0
Mas marami yata, mas okay
04:37.0
kasi yung some lie detector test,
04:39.0
they even include MRI kay iyong utak
04:42.0
para makita nila kung ikaw ay nagsisinungaling o hindi.
04:46.0
But all of this can be fool,
04:48.0
pero mamaya natin yan pag-uusapan.
04:51.0
So ngayon mga kamates, mga kaibigan,
04:53.0
sa polygraph test kasi,
04:55.0
there are many types of results.
04:59.0
Sa tingin ko, yung pinaka positive,
05:01.0
yung kalabos kong.
05:02.0
Best example to nang yung mga participants
05:05.0
are not in a stressful situation.
05:07.0
Obvious naman siguro,
05:09.0
nawala sila sa stressful situation
05:12.0
kasi ang saya nila parehas.
05:14.0
Obviously, hindi ito yung hinahanap natin.
05:18.0
What we're looking at,
05:19.0
mga kamates, mga kaibigan,
05:20.0
is yung tinatawag nating false positive
05:23.0
at saka false negative.
05:25.0
Kasi since ang measurement ng polygraph test
05:28.0
is highly subjected doon sa tinetest,
05:34.0
it means yung current state of mind
05:37.0
ng tinetest is what matters most.
05:40.0
And each individual is very different.
05:43.0
Isang problema sa mga polygraph test
05:46.0
is there is no standardized test.
05:49.0
Diba kasi sa IQ may standardized test.
05:51.0
Sa mga, yung GDP, GDA,
05:55.0
GDA ba tawag doon?
05:56.0
Yung sa high school literacy test,
06:02.0
Sa pagka nage-exam ka sa college,
06:04.0
all of these are standardized test
06:06.0
na makikita yung mental aptitude
06:09.0
Unlike sa polygraph test kasi,
06:11.0
ang problema kasi sa kanya,
06:13.0
mga kamates, mga kaibigan,
06:15.0
yung initial state ng tao,
06:18.0
yung pinagbabasihan niya.
06:19.0
Ibig sabihin, kunyari si Boskong,
06:21.0
since si Boskong healthy living na ngayon,
06:23.0
iba yung initial state niya sa akin
06:25.0
kasi siguro dahil mas mataba ako ngayon,
06:28.0
high blood, mas high blood ako.
06:31.0
So, dito pa lang makikita niya,
06:33.0
mga kamates, mga kaibigan,
06:34.0
sa blood pressure pa lang,
06:35.0
magkaiba na agad kami
06:37.0
ng initial state,
06:39.0
mga kamates, mga kaibigan.
06:40.0
So, ibig sabihin,
06:42.0
baka yung level niya,
06:47.0
pag tinanong kami niyan,
06:48.0
baka magkaiba yung sagot namin
06:50.0
even if we are being truthful
06:53.0
Okay, mga kamates, mga kaibigan,
06:56.0
nalalaman natin sa ating guest speaker,
06:59.0
why this is not admissible in court.
07:01.0
So, may apat na sagot
07:03.0
sa isang polygraph test.
07:05.0
Actually, lahat naman ang test
07:08.0
Ito, yung tinatawag na
07:11.0
false positive, false negative,
07:13.0
true positive, at saka true negative.
07:15.0
Most likely yung kilakong TV,
07:19.0
dito yan sa true positive.
07:21.0
there is really no stress
07:23.0
doon sa ginagawa natin.
07:24.0
Nakikita nating lahat
07:25.0
na masaya silang nagvlog doon.
07:28.0
if that is not indication
07:30.0
of they are telling the truth
07:31.0
and nothing but the truth,
07:32.0
I don't know what is.
07:34.0
Pero, minsan kasi sa mga polygraph test,
07:37.0
nakakaroon tayo ng tinatawag
07:39.0
na false positive,
07:41.0
at saka false negative.
07:43.0
Yung false positive,
07:44.0
nagsasabi siya ng totoo,
07:46.0
pero sinabi ng polygraph test
07:50.0
Pero sobrang stress niya lang talaga.
07:52.0
Kinuha yung initial condition niya,
07:53.0
kaso kabadong kabado siya
08:02.0
baka gugulpin siya pagkatapos
08:05.0
or talagang nervyoso siya.
08:07.0
So, minsan nakakaroon tayo
08:09.0
ng false positive.
08:10.0
Meron naman din false negative.
08:12.0
Nagsasabi siya ng kasinungalingan,
08:14.0
pero totoo yung sinasabi niya.
08:16.0
Eto yung magagaling magsinungaling talaga.
08:18.0
They can almost keep their levels
08:25.0
parang kukunin yung initial standard,
08:28.0
yung standard conditions mo
08:30.0
for these four tests.
08:32.0
Blood pressure, pulse, respiration,
08:34.0
skin contractivity.
08:35.0
If sobrang kalmado ng tao,
08:37.0
pucha pare, mahihirapan kang
08:39.0
arokin ng totoo dyan.
08:41.0
Usually, false negative yung nakukuha mo
08:43.0
sa mga ganyang klaseng tao.
08:47.0
Okay lang sana yung mga ganyan
08:51.0
or kapag alam mo na
08:54.0
hindi naman siguro trained
08:58.0
Yung mga normal na tao,
09:00.0
kaya yan, pero there are some people
09:02.0
na kayang talunin yan.
09:04.0
And that's why hindi siya siguro
09:06.0
admissible sa korte.
09:08.0
But again, andito si Fiscal EJ
09:10.0
para turuan tayo ng batas.
09:12.0
Okay, Fiscal, pasok!
09:14.0
So, yung unang tanong po
09:16.0
ni Sir Nico is, sabi niya,
09:18.0
bakit hindi pwede sa korte
09:20.0
ang lie detector test
09:26.0
Bali po yung premise na
09:30.0
accurate yung lie detector test
09:32.0
kasi if it's 99.99%
09:36.0
then it should have been already
09:38.0
admissible in court.
09:40.0
I will cite a case decided by
09:42.0
the Supreme Court explaining why
09:44.0
it is not admissible in evidence.
09:46.0
Supreme Court case
09:48.0
of Pipol versus Pablo
09:58.0
Ano ba ang sabi ng Supreme Court dito
10:00.0
with respect to the admissibility
10:02.0
of a lie detector test?
10:04.0
Yung accused dito kasi
10:06.0
was convicted of two counts of murder.
10:12.0
result daw ng polygraph test
10:14.0
niya should have been given weight
10:16.0
to tilt the scales of justice
10:20.0
Let me read to you the particular portion
10:24.0
of the Supreme Court
10:26.0
with respect to the admissibility
10:28.0
of a polygraph test.
10:30.0
Sabi ng Supreme Court,
10:32.0
a polygraph is an electromechanical
10:34.0
instrument that simultaneously measures
10:36.0
and records certain physiological
10:38.0
changes in the human body
10:40.0
that are believed to be involuntarily
10:42.0
caused by an examinee's conscious
10:44.0
attempt to deceive
10:48.0
The theory behind a polygraph or lie detector
10:50.0
test is that a person who lies
10:52.0
deliberately will have rising
10:54.0
blood pressure and a subconscious
10:56.0
block in breathing
10:58.0
which will be recorded on the graph.
11:00.0
However, American
11:02.0
courts almost uniformly
11:04.0
reject the results of polygraph
11:06.0
tests when offered in evidence
11:08.0
for the purposes of establishing
11:10.0
the guilt or innocence
11:12.0
of one accused of a crime.
11:14.0
Whether the accused
11:16.0
or the prosecution seeks its introduction
11:18.0
for the reason that
11:20.0
polygraph has not as yet
11:22.0
attained scientific acceptance
11:24.0
as a reliable and
11:28.0
truth or deception.
11:30.0
The rule is no different
11:32.0
in this jurisdiction.
11:34.0
Thus, in People v. Daniel
11:36.0
stating that much faith
11:38.0
and credit should not
11:42.0
lie detector test as it is
11:46.0
Appellant in this case has not
11:48.0
advanced any reason why this
11:50.0
rule should not apply
11:54.0
Hindi po kinatiga ng Supreme Court
12:02.0
sabihin yan, nag-negative siya sa
12:04.0
polygraph test, dapat
12:06.0
ma-acquit siya sa
12:08.0
criminal case filed against him
12:10.0
because, like what I said a while ago,
12:12.0
he was convicted in the
12:14.0
lower court for two counts of murder.
12:18.0
case reached the Supreme Court,
12:20.0
the Supreme Court
12:22.0
confirmed, or rather, affirmed
12:26.0
conviction of the accused for two
12:28.0
counts of murder.
12:32.0
Sir Nico's second question, sabi niya,
12:34.0
in your experience, meron po bang mga
12:36.0
cases na may naglapit ng result
12:38.0
ng lie detector test?
12:40.0
Si Nico David kasi matanong yung bata na yan
12:42.0
kaya kung gusto nyong malaman yung
12:44.0
sagot ni Fiscal EJ, just go to
12:46.0
his channel, Fiscal EJ
12:48.0
yung may punisher na picture
12:50.0
and then subscribe kayo doon. Tapos,
12:52.0
every Saturday po, may
12:54.0
livestream si Fiscal EJ. Pwede
12:56.0
kayong magtanong ng kahit anong related
12:58.0
sa batas natin, okay?
13:00.0
So, mga kamatis, mga kaibigan, what is
13:02.0
my final verdict dito? I think
13:04.0
ito yung tinatawag nating true positive
13:06.0
kasi nga, hindi naman sya 99.9%
13:10.0
there are studies that it is
13:12.0
close to 60 to 70%.
13:14.0
Sa tingin ko, ito yung nandito sa range
13:16.0
na to. Bakit ka mo? Kasi hindi
13:18.0
naman sila mukhang stress dito sa test
13:20.0
na to. Actually, nag-e-enjoy pa nga silang
13:22.0
dalawa e, diba? It's just
13:24.0
to affirm na nagmamahalan
13:26.0
silang dalawa. And,
13:28.0
yung, of course, yung kay Fiscal
13:30.0
EJ tsaka gusto ko lang
13:32.0
pakita sa inyo yung science nito
13:34.0
and how it affects
13:36.0
doon sa kung, ayan na, on
13:38.0
serious matters, ika nga. Pero,
13:40.0
like what I've said,
13:42.0
this is one of the rare instances, mga kamatis,
13:44.0
mga kaibigan, na I would
13:46.0
think that this is what we call
13:48.0
a true positive, okay?
13:50.0
True positive yan. Positive love,
13:52.0
diba? So, of course,
13:54.0
congratulations lagi kay
13:56.0
boss ko nga tsaka kay
13:58.0
ate V, dahil sobrang naging
14:00.0
successful nila dito sa social media and
14:02.0
sa tingin ko naman yung buhay nila
14:04.0
ay bukas na libro and alam naman natin na
14:06.0
for the longest time, diba?
14:08.0
Na nandito si boss ko sa
14:10.0
social media, walang ka-issue-issue
14:12.0
yan. So, ma-affirm
14:16.0
alam natin sa kanila that they are
14:18.0
telling the truth and nothing
14:20.0
but the truth. And I rest my case.
14:22.0
Pumunta tayo kay Fiscal EJ.
14:24.0
Yun lang naman yung sa akin for today.
14:26.0
Ge-ge-lords. Bye-bye!
