Tabletky obsahujúce len cukor, injekcie ničoho -- výskumy ukazujú, že placebo naozaj účinkuje -- častejšie, ako by ste si možno mysleli. Iluzionista Eric Mead na podujatí TEDMED ukazuje kúzlo, ktorým ilustruje, že aj keď viete, že niečo nie je skutočné, reagujete tak, ako keby to skutočné bolo. (Upozornenie: Toto vystúpenie nie je vhodné pre ľudí, ktorým je nevoľno pri pohľade na ihly alebo krv.)

For some time I have been interested in
0
3000
2000
Už nejaký čas sa zaujímam
00:20
the placebo effect,
1
5000
2000
o placebo efekt.
00:22
which might seem like an odd thing
2
7000
2000
Možno sa vám zdá zvláštne,
00:24
for a magician to be interested in,
3
9000
2000
že sa o také niečo zaujíma iluzionista,
00:26
unless you think of it in the terms that I do,
4
11000
2000
ale pozrite sa na vec z môjho pohľadu:
00:28
which is, "Something fake
5
13000
4000
"Niečomu, čo nie je skutočné,
00:32
is believed in enough by somebody
6
17000
2000
ľudia veria tak veľmi,
00:34
that it becomes something real."
7
19000
2000
že sa to stane skutočným."
00:36
In other words, sugar pills
8
21000
2000
Inak povedané, tabletky obsahujúce len cukor
00:38
have a measurable effect in certain kinds of studies,
9
23000
3000
majú v niektorých výskumoch merateľný účinok,
00:41
the placebo effect,
10
26000
2000
takzvaný placebo efekt.
00:43
just because the person thinks
11
28000
3000
Len preto, že človek verí,
00:46
that what's happening to them is a pharmaceutical
12
31000
2000
že to, čo sa s ním deje, je farmaceutického základu,
00:48
or some sort of a --
13
33000
3000
alebo je to napríklad
00:51
for pain management, for example,
14
36000
2000
niečo na tlmenie bolesti,
00:53
if they believe it enough there is a measurable effect in the body
15
38000
2000
ak tomu veria dostatočne, tak prichádza merateľný účinok,
00:55
called the placebo effect.
16
40000
2000
ktorý sa nazýva placebo efekt.
00:57
Something fake becomes
17
42000
2000
Niečo predstierané
00:59
something real
18
44000
2000
sa stáva skutočnosťou
01:01
because of someone's perception of it.
19
46000
3000
len kvôli tomu, ako to ľudia vnímajú.
01:04
In order for us to understand each other,
20
49000
2000
Aby sme si navzájom rozumeli,
01:06
I want to start by showing you a rudimentary,
21
51000
2000
chcem začať tým, že vám predvediem základný,
01:08
very simple magic trick.
22
53000
2000
veľmi jednoduchý trik.
01:10
And I'm going to show you how it works. This is a trick
23
55000
2000
A potom vám prezradím jeho princíp.
01:12
that's been in every children's magic book since at least the 1950s.
24
57000
4000
Tento trik je v každej knihe kúziel pre deti aspoň od 50-tych rokov.
01:16
I learned it myself from Cub Scout Magic in the 1970s.
25
61000
4000
Ja sám som sa ho naučil z Knihy kúziel pre skautov okolo roku 1970.
01:20
I'll do it for you, and then I'll explain it.
26
65000
2000
Najskôr ho predvediem a potom ho vysvetlím.
01:22
And then I'll explain why I explained it.
27
67000
3000
A hneď potom vysvetlím, prečo som ho vysvetlil.
01:25
So, here's what happens.
28
70000
2000
Takže takto sa to začína:
01:27
The knife, which you can examine; my hand, which you could examine.
29
72000
2000
Moja ruka a nôž, obidve si môžete prezrieť.
01:29
I'm just going to hold the knife in my fist like this.
30
74000
3000
Nôž chytím takto pevne do dlane.
01:32
I'll get my sleeve back.
31
77000
2000
Odhrniem si rukáv.
01:34
And to make sure nothing goes up or down my sleeve
32
79000
2000
A pre istotu, že mi nič nepôjde z rukáva,
01:36
I'm just going to squeeze my wrist right here.
33
81000
3000
si budem pevne držať aj zápästie.
01:39
That way you can see that at no time
34
84000
2000
Tak si môžete byť istí,
01:41
can anything travel, as long as I'm squeezing there
35
86000
2000
že kým pevne zvieram zápästie,
01:43
nothing can go up or down my sleeve.
36
88000
3000
nič mi nepôjde z rukáva ani do neho.
01:46
And the object of this is quite simple.
37
91000
2000
Zámer tohto všetkého je jednoduchý.
01:48
I'm going to open my hand,
38
93000
3000
Pomaly otvorím dlaň
01:51
and hopefully, if all is well,
39
96000
3000
a ak všetko pôjde, ako má,
01:54
my pure animal magnetism will hold the knife.
40
99000
3000
môj čistý živočíšny magnetizmus udrží ten nôž.
01:57
In fact it's held so tightly in place
41
102000
2000
Drží tam vlastne tak silno,
01:59
that I can shake it,
42
104000
2000
že ním môžem aj triasť,
02:01
and the knife does not come off.
43
106000
3000
a ten nôž nespadne.
02:04
Nothing goes up or down my sleeve,
44
109000
2000
A nič sa nehýbalo z môjho rukáva ani do neho,
02:06
no trickery. And you can examine everything.
45
111000
3000
žiadne podvody. A všetko si môžete prezrieť.
02:09
Ta-da!
46
114000
2000
Ta-da!
02:11
(Applause)
47
116000
2000
(Potlesk)
02:13
So, this is a trick that I often teach to young children
48
118000
3000
Toto je trik, ktorý často učím deti,
02:16
that are interested in magic, because you can learn
49
121000
2000
ktoré sa zaujímajú o kúzla, pretože sa z neho
02:18
a great deal about deception by studying
50
123000
2000
naučíte veľa o podvádzaní a ilúziách,
02:20
this very -- even though it's a very simple trick methodologically.
51
125000
3000
aj keď je to veľmi jednoduchý trik.
02:23
Probably many of you in the room know this trick.
52
128000
2000
Pravdepodobne mnoho z prítomných pozná tento trik.
02:25
What happens is this.
53
130000
2000
V skutočnosti sa deje toto.
02:27
I hold the knife in my hand.
54
132000
2000
Najskôr držím nôž v ruke.
02:29
I say I'm going to grab hold of my wrist
55
134000
2000
Vravím, že si budem držať zápästie,
02:31
to make sure nothing goes up or down my sleeve,
56
136000
2000
aby sme sa uistili, že mi nič nepôjde z rukáva.
02:33
that is a lie.
57
138000
2000
To je lož.
02:35
The reason I'm holding onto my wrist
58
140000
2000
Dôvod, prečo držím svoje zápästie,
02:37
is because that's actually the secret
59
142000
2000
je priamo tajomstvom
02:39
of the illusion.
60
144000
2000
tohto triku.
02:41
In a moment when my hand moves from facing you
61
146000
2000
V momente, keď otáčam ruku smerom od vás,
02:43
to being away from you,
62
148000
2000
aby ste mi nevideli do dlane,
02:45
this finger right here, my index finger is just going to shift
63
150000
2000
tento prst, môj ukazovák, sa presunie
02:47
from where it is, to a position
64
152000
3000
zo svojho miesta do pozície,
02:50
pointing out like this.
65
155000
2000
kde takto trčí.
02:52
Nice one.
66
157000
2000
Áno, úžasné.
02:54
Someone who didn't have a childhood is out there.
67
159000
3000
V hľadisku je niekto, kto nemal detstvo.
02:57
(Laughter)
68
162000
2000
(Smiech)
02:59
So, it goes like this, from here, right.
69
164000
2000
Takže, presúva sa takto.
03:01
And as I move around my finger shifts.
70
166000
2000
Keď otočím ruku, prst sa presunie.
03:03
And we could talk about why this is deceptive,
71
168000
2000
A mohli by sme sa rozprávať, prečo vás to oklame,
03:05
why you don't notice there are only three fingers down here,
72
170000
3000
prečo si nevšimnete, že tu dole sú len tri prsty,
03:08
because the mind, and the way it processes information,
73
173000
2000
je to kvôli mysli a spôsobu, akým spracováva informácie,
03:10
it doesn't count, one, two, three. It groups them.
74
175000
3000
myseľ nepočíta, jeden, dva, tri, ale vytvára skupiny.
03:13
But that's not really what this is about. Right? And then I open my hand up.
75
178000
2000
Ale o to vlastne nejde. A potom otvorím ruku.
03:15
Obviously it's clinging there, not by animal magnetism,
76
180000
4000
Samozrejme, nedrží tam živočíšnym magnetizmom,
03:19
but by chicanery,
77
184000
2000
ale trikom,
03:21
my index finger being there.
78
186000
3000
pretože tam mám ukazovák.
03:24
And then when I close my finger, same thing,
79
189000
2000
A presne to isté sa stane, keď zavriem dlaň,
03:26
as I move back, this motion
80
191000
2000
keď otáčam ruku naspäť,
03:28
kind of covers the moving back of my finger.
81
193000
2000
ten pohyb vlastne kryje pohyb toho prsta.
03:30
I take this hand away. You give the knife out.
82
195000
2000
Teraz môžem ruku pustiť a vrátiť nôž.
03:32
There is a trick you can do for your friends and neighbors. Thanks.
83
197000
4000
Je to trik, ktorý môžete ukázať priateľom a susedom. Ďakujem.
03:36
Now, (Laughter)
84
201000
2000
(Smiech)
03:38
what does that have to do with the placebo effect?
85
203000
3000
A ako s tým súvisí ten placebo efekt?
03:41
I read a study a year or so ago
86
206000
3000
Asi pred rokom som čítal jednu analýzu,
03:44
that really blew my mind wide open.
87
209000
3000
ktorá ma naozaj ohromila.
03:47
I'm not a doctor or a researcher, so this, to me,
88
212000
2000
Nie som doktor ani výskumník,
03:49
was an astonishing thing.
89
214000
2000
takže ma to naozaj prekvapilo.
03:51
It turns out that if you administer
90
216000
2000
Ukázalo sa, že ak podáte
03:53
a placebo in the form of a white pill,
91
218000
2000
placebo vo forme bielej tabletky,
03:55
that's like aspirin shaped --
92
220000
3000
teda tvaru asi ako aspirín --
03:58
it's just a round white pill -- it has some certain measurable effect.
93
223000
3000
okrúhla biela tabletka -- dosiahnete istý merateľný výsledok.
04:01
But if you change the form that you give the placebo in,
94
226000
3000
Ale ak zmeníte formu, ktorou placebo podávate,
04:04
like you make a smaller pill,
95
229000
2000
napríklad použijete menšiu tabletku
04:06
and color it blue, and stamp a letter into it,
96
231000
3000
modrej farby a s vyrazeným písmenom,
04:09
it is actually measurably more effective.
97
234000
3000
bude to mať merateľne vyšší účinok.
04:12
Even though neither one of these things
98
237000
2000
Aj napriek tomu, že farmaceutický účinok
04:14
has any pharmaceutical -- they're sugar pills.
99
239000
3000
nemá ani jedna -- je to len cukor.
04:17
But a white pill is not as good as a blue pill.
100
242000
3000
Ale modrá tabletka je lepšia ako biela tabletka.
04:21
What? (Laughter) That really flipped me out.
101
246000
3000
Čože? (Smiech) To ma naozaj dostalo.
04:24
Turns out though, that that's not even where it stops.
102
249000
2000
Ukazuje sa však, že farbou to nekončí.
04:26
If you have capsules,
103
251000
3000
Ak použijete kapsuly, účinok bude väčší,
04:29
they're more effective than tablets in any form.
104
254000
2000
ako z akýchkoľvek tabliet.
04:31
A colored capsule, that's yellow on one end and red on the other
105
256000
3000
A farebná kapsula, napríklad žlto-červená,
04:34
is better than a white capsule.
106
259000
2000
je lepšia ako biela.
04:36
Dosage has something to do with this.
107
261000
2000
Na dávkovaní tiež záleží.
04:38
One pill twice a day
108
263000
2000
Jedna tableta dvakrát denne
04:40
is not as good at three pills --
109
265000
3000
nie je taká dobrá ako tri tablety...
04:43
I don't remember the statistic now. Sorry.
110
268000
2000
nepamätám si tie štatistiky presne. Prepáčte.
04:45
But the point is ...
111
270000
2000
Ale pointa je...
04:47
(Laughter) ... these dosages have something to do with it.
112
272000
2000
(Smiech) ...že aj na dávkovaní záleží.
04:49
And the form has something to do with it.
113
274000
2000
Tak ako záleží aj na forme.
04:51
And if you want the ultimate in placebo,
114
276000
3000
Ale ak chcete najlepšie placebo,
04:54
you've go to the needle.
115
279000
3000
siahnite po injekciách.
04:57
Right? A syringe with some inert --
116
282000
2000
Injekcia s niečím, čo nereaguje --
04:59
a couple CCs of some inert something,
117
284000
2000
keď vpichnete niekoľko mililitrov
05:01
and you inject this into a patient ...
118
286000
2000
niečoho takého pacientovi,
05:03
Well this is such a powerful image in their mind,
119
288000
2000
vyvolá to v jeho mysli veľmi silnú predstavu --
05:05
it's so much stronger than the white pill.
120
290000
2000
je to mnohonásobne silnejšie ako biela tableta.
05:07
It's a really, this graph, well I'll show it to you
121
292000
3000
Ten graf to výborne ukazuje --
05:10
some other time when we have slides.
122
295000
2000
ukážem vám ho, ale až niekedy nabudúce.
05:12
The point is
123
297000
2000
Pointa ale je,
05:14
the white pill is not as good as the blue pill
124
299000
3000
že biela tableta je horšia ako modrá tableta,
05:17
is not as good as the capsule is not as good as the needle.
125
302000
3000
ktorá je horšia ako kapsula, ktorá ale nemá na injekciu.
05:20
And none of it has any real pharmaceutical quality,
126
305000
3000
A nič z toho nemá farmaceutický základ,
05:23
it's only your belief that makes it real
127
308000
4000
len vaša viera to robí skutočným
05:27
in your body and makes a stronger effect.
128
312000
3000
a spôsobuje silnejší účinok vo vašom tele.
05:30
I wanted to see if I could take that idea
129
315000
2000
Chcel som zistiť, či sa táto myšlienka
05:32
and apply it to a magic trick.
130
317000
2000
dá využiť v nejakom kúzelníckom triku.
05:34
And take something that is obviously a fake trick
131
319000
4000
Zmeniť niečo, čo je očividne len trik,
05:38
and make it seem real.
132
323000
3000
na niečo, čo sa bude zdať skutočné.
05:43
And we know from that study
133
328000
3000
A zo spomínanej štúdie vieme,
05:46
that when you want reality, you go to the needle.
134
331000
4000
že keď chcete skutočnosť, siahnete po ihlách.
05:50
This is a seven-inch hatpin. It's very, very sharp,
135
335000
4000
Toto je 18cm dlhá klobúková ihlica. Je veľmi ostrá.
05:54
and I'm going to just sterilize it a tiny bit.
136
339000
5000
Len ju trochu sterilizujem.
06:01
This is really my flesh. This is not
137
346000
2000
Toto je naozaj moje telo.
06:03
Damian's special-grown flesh.
138
348000
2000
Nie je to žiadna umelo vytvorená ruka.
06:05
That's my skin right there. This is not a Hollywood special effect.
139
350000
3000
A toto tu je moja koža. Nie je to žiadny Hollywoodsky efekt.
06:10
I'm going to pierce my skin
140
355000
2000
Teraz prepichnem kožu tak,
06:12
and run this needle through to the other side.
141
357000
2000
aby ihla vyšla na druhej strane.
06:14
If you're queasy -- (Laughs)
142
359000
3000
Ak vám býva nevoľno alebo rýchlo omdlievate...
06:17
if you faint easily -- I was doing this for some friends
143
362000
2000
(Smiech) Ukazoval som to včera večer v hoteli
06:19
in the hotel room last night, and some people that I didn't know,
144
364000
3000
niekoľkým známym a aj neznámym ľuďom
06:22
and one woman almost passed out.
145
367000
2000
a jedna že skoro omdlela.
06:24
So, I suggest if you get queasy easy
146
369000
3000
Takže navrhujem, ak vám býva nevoľno,
06:27
that you look away for about the next 30 --
147
372000
2000
pozerajte sa inam najbližších asi 30 --
06:29
in fact, you know what, I'll do the first bad part behind it.
148
374000
2000
alebo, urobím tú prvú časť z druhej strany.
06:31
You'll get to see, you can look away too if you'd like to.
149
376000
4000
Vy to budete vidieť, ale môžete sa pozerať preč, ak chcete.
06:35
So, here is what happens, right here,
150
380000
2000
Takže kým nevidíte,
06:37
the beginning of my flesh
151
382000
2000
v spodnej časti ruky,
06:39
at the lower part of my arm I just make
152
384000
2000
tam, kde začína svalstvo,
06:41
a little pierce.
153
386000
2000
robím malý vpich.
06:43
I'm sorry, man. Am I freaking you out?
154
388000
2000
Prepáčte tam vzadu, desí vás to?
06:45
OK, and then just through my skin a tiny bit,
155
390000
4000
OK, a teraz chvíľu cez kožu,
06:49
and then out the other side like this.
156
394000
3000
a nakoniec von na druhej strane.
06:52
Now, essentially we're in the same position we were in
157
397000
4000
Teraz sme vlastne v rovnakom stave,
06:56
with the knife trick.
158
401000
2000
ako v triku s nožom.
06:58
(Laughter)
159
403000
4000
(Smiech)
07:02
Sort of.
160
407000
2000
Skoro.
07:04
But you can't count my fingers right now can you?
161
409000
3000
Ale teraz mi už nemôžete počítať prsty, však?
07:07
So, let me show them to you. That's one, two
162
412000
2000
Tak vám ich ukážem. Prvý, druhý,
07:09
three, four, five.
163
414000
3000
tretí, štvrtý, piaty.
07:12
Yes, well...
164
417000
3000
Áno,...
07:15
I know what people think when they see this.
165
420000
2000
viem, čo si ľudia myslia, keď vidia toto.
07:17
They go, "Well, he's certainly not dumb enough
166
422000
2000
Myslia si: "Určite nie je taký hlúpy,
07:19
to stab himself through the skin to entertain us for a few minutes.
167
424000
3000
že by si prepichol kožu, aby nás na pár minút zabavil."
07:22
So, let me give you a little peek.
168
427000
3000
Tak sa na to pozrime.
07:25
How's that look out there? Pretty good.
169
430000
2000
Ako to tam vyzerá? Celkom dobre.
07:27
(Laughs)
170
432000
3000
(Smiech)
07:30
Yeah, I know. (Laughs)
171
435000
3000
Áno, áno, viem. (Smiech)
07:33
And the people in the back go, "OK, I didn't really see that."
172
438000
2000
A tí vzadu vravia: "Veď som tam poriadne ani nevidel."
07:35
People in the satellite room are starting to move in now.
173
440000
3000
Ľudia sa pozerajú na svoje obrazovky z bližšia.
07:38
Let me give you good close look at this.
174
443000
2000
Pozrite sa na to teda dobre z blízka.
07:40
That really is my skin. That is not a Hollywood special effect.
175
445000
3000
To je naozaj moja koža. Nie je to žiadny Hollywoodsky efekt.
07:43
That's my flesh, and I can twist that around.
176
448000
3000
To sú moje svaly, môžem tým aj hýbať.
07:46
I'm sorry. If you're getting queasy, look away,
177
451000
2000
Ospravedlňujem sa -- ak vám je nevoľno,
07:48
don't look at the thing.
178
453000
2000
nepozerajte sa na to.
07:50
People in the back or people on video years from now watching this
179
455000
2000
Ľudia vzadu aj tí, čo to ešte len budú pozerať na videu
07:52
will go, "Well yeah, that looks kind of neat
180
457000
3000
povedia: "No áno, vyzerá to celkom dobre,
07:55
in some sort of effect there, but if it were real he would be --
181
460000
3000
je to celkom dobrý trik, ale keby to bolo naozaj --
07:58
see there's a hole there and a hole there, if it were real he would be bleeding.
182
463000
3000
veď má ranu na jednej aj druhej strane, keby to bolo naozaj, tak by krvácal."
08:01
Well let me work up some blood for you.
183
466000
3000
Tak vám ukážem trochu krvi.
08:04
(Laughter)
184
469000
5000
(Smiech)
08:09
Yes, there it is.
185
474000
2000
Áno, tu ju máme.
08:11
(Applause)
186
476000
6000
(Potlesk)
08:27
(Laughter)
187
492000
3000
(Smiech)
08:30
Normally now, I would take the needle out.
188
495000
3000
Za normálnych okolností by som tú ihlu teraz vytiahol.
08:33
I would clean off my arm, and I would show you that there are no wounds.
189
498000
3000
Vyčistil by som si ruku a ukázal vám, že nemám žiadne rany.
08:36
But I think in this context
190
501000
3000
Ale myslím si, že v dnešnom kontexte,
08:39
and with the idea of taking something fake
191
504000
2000
v kontexte nepravých vecí,
08:41
and making it into something real,
192
506000
3000
ktoré pretvárame na veci skutočné,
08:44
I'm just going to leave it there,
193
509000
2000
si ju tam nechám zapichnutú
08:46
and walk off the stage.
194
511000
2000
a odídem z pódia.
08:48
(Laughter)
195
513000
2000
(Smiech)
08:50
I will be seeing you several times over the next few days.
196
515000
3000
Počas najbližších dní sa ešte niekoľkokrát uvidíme.
08:53
I hope you're looking forward to that. Thank you very much.
197
518000
3000
Dúfam, že sa na to tešíte. Ďakujem veľmi pekne.
08:56
(Laughter)
198
521000
2000
(Smiech)
08:58
(Applause)

ABOUT THE SPEAKER
Eric Mead - MagicianEric Mead is a prolific magician, mentalist and comedian who worked his way up from doing magic on the street to appearing at exclusive events around the world.
Why you should listen
As a child, Eric Mead says that he had a typical interest in magic. However, by the time he was a teenager, his interest had grown to a full-fledged obsession -- he was getting paid to do birthday parties and banquets in his hometown. He began street performing in 1985 and four years later was offered a job as “Magic Bartender” at the Tower Comedy/Magic Bar owned by John Denver. Working at the bar, as well as private parties and comedy clubs, he became well-known in the industry and went on to perform one of the most memorable pieces in The Aristocrats.
Mead is also known as the author of Tangled Web, a collection of magic and mentalism taken from his personal repertoire.
