收集更多的數據會導向更好的決策嗎？有競爭力、數據頂尖的公司，如 Amazon、Google 和 Netflix 已經知道數據分析本身並不總能產生最佳的效果。在這次講座中，數據科學家塞巴斯蒂安．韋尼克剖析了當我們純粹用數據做決策時會發生甚麼錯誤，並建議我們一個更聰明的方式來使用它。

even though he may have been responsible

即使他曾負責過
你生命中平凡無奇的22分鐘，
你生命中平凡無奇的22分鐘，

minutes of your life on April 19, 2013.
minutes of your life on April 19, 2013.

在2013年4月19日這一天。
00:26
He may have also been responsible
for 22 very entertaining minutes,
for 22 very entertaining minutes,

14560
3176
他也許也曾負責帶給
各位非常歡樂的22分鐘，
各位非常歡樂的22分鐘，
00:29
but not very many of you.
4
17760
2256
但你們其中也許很多人並沒有。
00:32
And all of that goes back to a decision
5
20040
1896
而這一切全部要回到
00:33
that Roy had to make
about three years ago.
about three years ago.
6
21960
2000
Roy在三年前的一個決定。
00:35
So you see, Roy Price
is a senior executive with Amazon Studios.
is a senior executive with Amazon Studios.
7
23984
4832
所以，你明白，Roy Price是
Amazon廣播公司的一位資深決策者。
Amazon廣播公司的一位資深決策者。
00:40
That's the TV production
company of Amazon.
company of Amazon.
8
28840
3016
這是Amazon旗下的一家
電視節目製作公司。
電視節目製作公司。
00:43
He's 47 years old, slim, spiky hair,
9
31880
3256
他47歲，身材不錯，尖頭髮，
00:47
describes himself on Twitter
as "movies, TV, technology, tacos."
as "movies, TV, technology, tacos."
10
35160
4816
在Twitter上形容自己是
“電影、電視、科技、墨西哥捲餅 。”
“電影、電視、科技、墨西哥捲餅 。”
00:52
And Roy Price has a very responsible job,
because it's his responsibility
because it's his responsibility
11
40000
5176
Roy Price有一個
責任非常重大的工作，
責任非常重大的工作，
因為他要負責幫Amazon挑選
即將製作的原創內容節目。
即將製作的原創內容節目。
00:57
to pick the shows, the original content
that Amazon is going to make.
that Amazon is going to make.
12
45200
4056
01:01
And of course that's
a highly competitive space.
a highly competitive space.
13
49280
2336
當然，這是高度競爭的領域。
01:03
I mean, there are so many
TV shows already out there,
TV shows already out there,
14
51640
2736
我的意思是，
外面已經有那麼多的電視節目，
外面已經有那麼多的電視節目，
01:06
that Roy can't just choose any show.
15
54400
2176
Roy不能隨便亂挑一個節目。
01:08
He has to find shows
that are really, really great.
that are really, really great.
16
56600
4096
他必須找出真正、
真正很讚的節目。
真正很讚的節目。
01:12
So in other words, he has to find shows
17
60720
2816
換句話說，
他必須從這條曲線上的右邊挑選節目。
01:15
that are on the very right end
of this curve here.
of this curve here.
18
63560
2376
01:17
So this curve here
is the rating distribution
is the rating distribution
19
65960
2656
這條曲線是 IMDB網路電影資料庫裡
01:20
of about 2,500 TV shows
on the website IMDB,
on the website IMDB,
20
68640
4376
2500個電視節目的
客戶評分分布圖，
客戶評分分布圖，
01:25
and the rating goes from one to 10,
21
73040
2896
評分從 1到10，
01:27
and the height here shows you
how many shows get that rating.
how many shows get that rating.
22
75960
2976
最高的地方代表
有多少節目達到這個評分。
有多少節目達到這個評分。
01:30
So if your show gets a rating
of nine points or higher, that's a winner.
of nine points or higher, that's a winner.
23
78960
4696
所以如果你的節目達到 9分或更高，
你就是贏家。
你就是贏家。
01:35
Then you have a top two percent show.
24
83680
1816
你就是那百分之二的頂尖節目。
01:37
That's shows like "Breaking Bad,"
"Game of Thrones," "The Wire,"
"Game of Thrones," "The Wire,"
25
85520
3896
例如像是" 絕命毒師 、
權力遊戲、火線重案組 "
權力遊戲、火線重案組 "
01:41
so all of these shows that are addictive,
26
89440
2296
全部都是會讓你上癮的節目，
01:43
whereafter you've watched a season,
your brain is basically like,
your brain is basically like,
27
91760
3056
看完一季之後，你的大腦基本上像是 ...
01:46
"Where can I get more of these episodes?"
28
94840
2176
" 我要去哪裡找到更多這部片的影集？ "
01:49
That kind of show.
29
97040
1200
等等這類的節目。
01:50
On the left side, just for clarity,
here on that end,
here on that end,
30
98920
2496
左邊末端，很明顯地，
你們有個叫" 小小姐與后冠 "的節目
01:53
you have a show called
"Toddlers and Tiaras" --
"Toddlers and Tiaras" --
31
101440
3176
01:56
(Laughter)
32
104640
2656
（笑聲）
一個足夠讓你明白
01:59
-- which should tell you enough
33
107320
1536
02:00
about what's going on
on that end of the curve.
on that end of the curve.
34
108880
2191
為什麼它會在曲線末端的節目。
02:03
Now, Roy Price is not worried about
getting on the left end of the curve,
getting on the left end of the curve,
35
111095
4161
現在，Roy Price不擔心
在曲線左邊末端的節目。
在曲線左邊末端的節目。
02:07
because I think you would have to have
some serious brainpower
some serious brainpower
36
115280
2936
因為我認為你們都會想
有一些嚴肅的判斷力
有一些嚴肅的判斷力
02:10
to undercut "Toddlers and Tiaras."
37
118240
1696
來降低" 小小姐與后冠 "的評分 。
02:11
So what he's worried about
is this middle bulge here,
is this middle bulge here,
38
119960
3936
所以，他擔心的是中間多數的這些節目，
多到爆的這些一般性電視節目，
02:15
the bulge of average TV,
39
123920
1816
02:17
you know, those shows
that aren't really good or really bad,
that aren't really good or really bad,
40
125760
2856
你知道，這些節目
既不是很好也不是很壞，
既不是很好也不是很壞，
02:20
they don't really get you excited.
41
128639
1656
它們不會真正地讓你興奮。
02:22
So he needs to make sure
that he's really on the right end of this.
that he's really on the right end of this.
42
130320
4856
所以他要確保他真的
是在右邊的末端這裡，
是在右邊的末端這裡，
02:27
So the pressure is on,
43
135200
1576
所以，壓力就來了，
02:28
and of course it's also the first time
44
136800
2176
所以當然，這也是第一次 Amazon
02:31
that Amazon is even
doing something like this,
doing something like this,
45
139000
2176
也想要做類似這樣的事情，
02:33
so Roy Price does not want
to take any chances.
to take any chances.
46
141200
3336
Roy Price不想冒風險，
他想要建造成功，
02:36
He wants to engineer success.
47
144560
2456
他要一個保證的成功，
02:39
He needs a guaranteed success,
48
147040
1776
02:40
and so what he does is,
he holds a competition.
he holds a competition.
49
148840
2576
所以他就舉辦一個比賽。
02:43
So he takes a bunch of ideas for TV shows,
50
151440
3136
他為電視節目帶來了很多想法，
02:46
and from those ideas,
through an evaluation,
through an evaluation,
51
154600
2296
並且透過一個評估，形塑這些想法，
02:48
they select eight candidates for TV shows,
52
156920
4096
他們為電視節目挑選了八個候選名單，
02:53
and then he just makes the first episode
of each one of these shows
of each one of these shows
53
161040
3216
然後他製作每一個節目的第一集，
02:56
and puts them online for free
for everyone to watch.
for everyone to watch.
54
164280
3136
然後把他們放到網路上，
讓每個人免費觀看。
讓每個人免費觀看。
02:59
And so when Amazon
is giving out free stuff,
is giving out free stuff,
55
167440
2256
所以當Amazon要給你免費的東西時，
03:01
you're going to take it, right?
56
169720
1536
你就會拿，對吧？
03:03
So millions of viewers
are watching those episodes.
are watching those episodes.
57
171280
5136
所以上百萬人在看這些影集，
而這些人不明白的是，
當他們在觀看節目的時候，
當他們在觀看節目的時候，
03:08
What they don't realize is that,
while they're watching their shows,
while they're watching their shows,
58
176440
3216
03:11
actually, they are being watched.
59
179680
2296
實際上他們也正被觀查中。
03:14
They are being watched
by Roy Price and his team,
by Roy Price and his team,
60
182000
2336
他們被Roy Price及他的團隊觀查，
03:16
who record everything.
61
184360
1376
他們紀錄了每一件事。
03:17
They record when somebody presses play,
when somebody presses pause,
when somebody presses pause,
62
185760
3376
他們紀錄了，那些人按了撥放，
那些人按了暫停，
那些人按了暫停，
03:21
what parts they skip,
what parts they watch again.
what parts they watch again.
63
189160
2536
那些部分他們跳過，
那些部分他們又重看一遍。
那些部分他們又重看一遍。
03:23
So they collect millions of data points,
64
191720
2256
所以他們收集了上百萬的數據資料，
03:26
because they want
to have those data points
to have those data points
65
194000
2096
因為他們想要用這些數據資料來決定
03:28
to then decide
which show they should make.
which show they should make.
66
196120
2696
要做甚麼樣的節目。
03:30
And sure enough,
so they collect all the data,
so they collect all the data,
67
198840
2176
確定好後，他們收集所有的數據，
03:33
they do all the data crunching,
and an answer emerges,
and an answer emerges,
68
201040
2576
他們做完所有數據處理後，
得到一個答案，
得到一個答案，
03:35
and the answer is,
69
203640
1216
而答案就是，
03:36
"Amazon should do a sitcom
about four Republican US Senators."
about four Republican US Senators."
70
204880
5536
" Amazon需要製作一個有關
美國共和黨參議員的喜劇 "。
美國共和黨參議員的喜劇 "。
03:42
They did that show.
71
210440
1216
他們做了，
03:43
So does anyone know the name of the show?
72
211680
2160
有人知道這個節目嗎？
（觀眾：" 艾爾發屋 "）
03:46
(Audience: "Alpha House.")
73
214720
1296
03:48
Yes, "Alpha House,"
74
216040
1456
是的，" 艾爾發屋 "
03:49
but it seems like not too many of you here
remember that show, actually,
remember that show, actually,
75
217520
4096
但實際上，你們大部人
應該不記得有這部片子，
應該不記得有這部片子，
03:53
because it didn't turn out that great.
76
221640
1856
因為這部片並不那麼賣座。
03:55
It's actually just an average show,
77
223520
1856
它實際上僅是一般的節目，
03:57
actually -- literally, in fact, because
the average of this curve here is at 7.4,
the average of this curve here is at 7.4,
78
225400
4576
實際上，一般的節目差不多
坐落在曲線上的 7.4分，
坐落在曲線上的 7.4分，
04:02
and "Alpha House" lands at 7.5,
79
230000
2416
而" 艾爾發房屋 "落在7.5分，
04:04
so a slightly above average show,
80
232440
2016
所以比一般的節目高一點點，
04:06
but certainly not what Roy Price
and his team were aiming for.
and his team were aiming for.
81
234480
2920
但絕對不是Roy Price與
他的團隊所要達到的目標。
他的團隊所要達到的目標。
這時，然而，同一時間，
04:10
Meanwhile, however,
at about the same time,
at about the same time,
82
238320
2856
另一家公司的另一個決策者，
04:13
at another company,
83
241200
1576
04:14
another executive did manage
to land a top show using data analysis,
to land a top show using data analysis,
84
242800
4216
用同樣的數據分析做了一個頂尖的節目，
04:19
and his name is Ted,
85
247040
1576
他的名字是 Ted，
04:20
Ted Sarandos, who is
the Chief Content Officer of Netflix,
the Chief Content Officer of Netflix,
86
248640
3416
Ted Sarandos是Netflix的
首席節目內容決策者，
首席節目內容決策者，
04:24
and just like Roy,
he's on a constant mission
he's on a constant mission
87
252080
2136
就跟 Roy一樣，他也要不停的找
04:26
to find that great TV show,
88
254240
1496
最棒的節目，
04:27
and he uses data as well to do that,
89
255760
2016
而他也使用數據來這樣做，
04:29
except he does it
a little bit differently.
a little bit differently.
90
257800
2015
但他的做法，有點不太一樣。
04:31
So instead of holding a competition,
what he did -- and his team of course --
what he did -- and his team of course --
91
259839
3737
不是舉辦比賽，當然，他和他的團隊
04:35
was they looked at all the data
they already had about Netflix viewers,
they already had about Netflix viewers,
92
263600
3536
也有觀察Netflix已經有的觀眾數據，
04:39
you know, the ratings
they give their shows,
they give their shows,
93
267160
2096
觀眾對節目的評分、觀看紀錄、
04:41
the viewing histories,
what shows people like, and so on.
what shows people like, and so on.
94
269280
2696
那些節目是人們喜歡的等等，
04:44
And then they use that data to discover
95
272000
1896
他們也使用數據去發掘
04:45
all of these little bits and pieces
about the audience:
about the audience:
96
273920
2616
觀眾所有的小細節：
他們喜歡甚麼類型的節目、
04:48
what kinds of shows they like,
97
276560
1456
04:50
what kind of producers,
what kind of actors.
what kind of actors.
98
278040
2096
甚麼類型的製作人、甚麼類型的演員，
04:52
And once they had
all of these pieces together,
all of these pieces together,
99
280160
2576
一旦他們收集全部的細節後，
04:54
they took a leap of faith,
100
282760
1656
他們很有信心地
04:56
and they decided to license
101
284440
2096
決定要製作一部，
04:58
not a sitcom about four Senators
102
286560
2456
不是四個參議員的喜劇，
05:01
but a drama series about a single Senator.
103
289040
2880
而是一系列有關一位
單身參議員的戲劇。
單身參議員的戲劇。
各位知道那個節目嗎？
05:04
You guys know the show?
104
292760
1656
05:06
(Laughter)
105
294440
1296
（笑聲）
05:07
Yes, "House of Cards," and Netflix
of course, nailed it with that show,
of course, nailed it with that show,
106
295760
3736
是的，" 纸牌屋 "，Netflix ，當然，
至少頭二季，用這節目盯住那個分數。
05:11
at least for the first two seasons.
107
299520
2136
05:13
(Laughter) (Applause)
108
301680
3976
（笑聲）（掌聲）
05:17
"House of Cards" gets
a 9.1 rating on this curve,
a 9.1 rating on this curve,
109
305680
3176
" 纸牌屋 "在這曲線上拿到 9.1分，
05:20
so it's exactly
where they wanted it to be.
where they wanted it to be.
110
308880
3176
這當然是他們想要的。
05:24
Now, the question of course is,
what happened here?
what happened here?
111
312080
2416
現在，當然問題就是
這到底是怎麼一回事？
這到底是怎麼一回事？
05:26
So you have two very competitive,
data-savvy companies.
data-savvy companies.
112
314520
2656
你有兩個非常有競爭力、
精通數據資料的公司。
精通數據資料的公司。
05:29
They connect all of these
millions of data points,
millions of data points,
113
317200
2856
他們連結了所有的數據資料，
05:32
and then it works
beautifully for one of them,
beautifully for one of them,
114
320080
2376
然後，其中一個做的很漂亮，
05:34
and it doesn't work for the other one.
115
322480
1856
而另一個卻沒有，
05:36
So why?
116
324360
1216
為什麼？
05:37
Because logic kind of tells you
that this should be working all the time.
that this should be working all the time.
117
325600
3456
因為邏輯上告訴你，
這應該每次都有效啊，
這應該每次都有效啊，
05:41
I mean, if you're collecting
millions of data points
millions of data points
118
329080
2456
我的意思是，
如果你收集了所有的數據資料
如果你收集了所有的數據資料
05:43
on a decision you're going to make,
119
331560
1736
來決定一個決策，
05:45
then you should be able
to make a pretty good decision.
to make a pretty good decision.
120
333320
2616
那你應該可以得到一個
相當不錯的決策。
相當不錯的決策。
05:47
You have 200 years
of statistics to rely on.
of statistics to rely on.
121
335960
2216
你有 200年的統計數據做後盾，
05:50
You're amplifying it
with very powerful computers.
with very powerful computers.
122
338200
3016
你用很強大的電腦去增強它，
05:53
The least you could expect
is good TV, right?
is good TV, right?
123
341240
3280
至少你可以期待到一個
好的電視節目，對吧？
好的電視節目，對吧？
05:57
And if data analysis
does not work that way,
does not work that way,
124
345880
2720
但如果數據分析
並沒有想像中的有效，
並沒有想像中的有效，
那，這真的有點恐怖，
06:01
then it actually gets a little scary,
125
349520
2056
06:03
because we live in a time
where we're turning to data more and more
where we're turning to data more and more
126
351600
3816
因為我們正轉向一個
數據越來越多的時代，
數據越來越多的時代，
06:07
to make very serious decisions
that go far beyond TV.
that go far beyond TV.
127
355440
4480
來做出遠比電視節目
還要嚴肅的決策。
還要嚴肅的決策。
06:12
Does anyone here know the company
Multi-Health Systems?
Multi-Health Systems?
128
360760
3240
你們當中有人知道" MHS "這家公司嗎？
沒人？好，這樣很好，
06:17
No one. OK, that's good actually.
129
365080
1656
06:18
OK, so Multi-Health Systems
is a software company,
is a software company,
130
366760
3216
好的，MHS是一家軟體公司，
06:22
and I hope that nobody here in this room
131
370000
2816
而我希望在座的各位，
沒有人與這個軟體有牽連，
06:24
ever comes into contact
with that software,
with that software,
132
372840
3176
06:28
because if you do,
it means you're in prison.
it means you're in prison.
133
376040
2096
因為如果你有，代表你在監獄中
06:30
(Laughter)
134
378160
1176
（笑聲）
06:31
If someone here in the US is in prison,
and they apply for parole,
and they apply for parole,
135
379360
3536
在美國這裡如果有人被判入監，
然後要申請假釋，
然後要申請假釋，
06:34
then it's very likely that
data analysis software from that company
data analysis software from that company
136
382920
4296
很有可能那家公司的數據分析軟體
06:39
will be used in determining
whether to grant that parole.
whether to grant that parole.
137
387240
3616
會被用來判定是否能獲得假釋。
06:42
So it's the same principle
as Amazon and Netflix,
as Amazon and Netflix,
138
390880
2576
所以，它也是採用
Amazon 和 Netflix 公司相同的原則，
Amazon 和 Netflix 公司相同的原則，
06:45
but now instead of deciding whether
a TV show is going to be good or bad,
a TV show is going to be good or bad,
139
393480
4616
但不同的是，
他們是用來決定電視節目將來的好壞，
他們是用來決定電視節目將來的好壞，
你是用來決定一個人將來的好壞，
06:50
you're deciding whether a person
is going to be good or bad.
is going to be good or bad.
140
398120
2896
06:53
And mediocre TV, 22 minutes,
that can be pretty bad,
that can be pretty bad,
141
401040
5496
表現普通22分鐘的電視節目，很糟糕，
06:58
but more years in prison,
I guess, even worse.
I guess, even worse.
142
406560
2640
但，我猜，要做更多年的牢，更糟糕。
但不幸的是，實際上已經有證據顯示，
該數據分析除了擁有龐大的數據外，
該數據分析除了擁有龐大的數據外，
07:02
And unfortunately, there is actually
some evidence that this data analysis,
some evidence that this data analysis,
143
410360
4136
07:06
despite having lots of data,
does not always produce optimum results.
does not always produce optimum results.
144
414520
4216
它並不總是跑出適當的結果。
07:10
And that's not because a company
like Multi-Health Systems
like Multi-Health Systems
145
418760
2722
但並不只有像是MHS這樣的軟體公司
07:13
doesn't know what to do with data.
146
421506
1627
不明白數據怎麼了，
07:15
Even the most data-savvy
companies get it wrong.
companies get it wrong.
147
423158
2298
甚至最頂尖的數據公司也會出錯，
07:17
Yes, even Google gets it wrong sometimes.
148
425480
2400
是的，甚至Google有時也會出錯。
07:20
In 2009, Google announced
that they were able, with data analysis,
that they were able, with data analysis,
149
428680
4496
2009年，Google宣布他們可以用數據分析，
來預測流行性感冒，討人厭的流感，
07:25
to predict outbreaks of influenza,
the nasty kind of flu,
the nasty kind of flu,
150
433200
4136
經由他們的Google搜尋引擎來做數據分析。
07:29
by doing data analysis
on their Google searches.
on their Google searches.
151
437360
3776
07:33
And it worked beautifully,
and it made a big splash in the news,
and it made a big splash in the news,
152
441160
3856
而且它準確無比，當時造成一股新聞的轟動，
07:37
including the pinnacle
of scientific success:
of scientific success:
153
445040
2136
包含一個科學界成功的高峰：
07:39
a publication in the journal "Nature."
154
447200
2456
在 "自然期刊"上發表文章。
07:41
It worked beautifully
for year after year after year,
for year after year after year,
155
449680
3616
之後的每一年，它都預測地很漂亮，
07:45
until one year it failed.
156
453320
1656
直到有一年它失敗了。
07:47
And nobody could even tell exactly why.
157
455000
2256
沒有人能正確地說明到底甚麼原因。
07:49
It just didn't work that year,
158
457280
1696
那一年它就是不準了，
07:51
and of course that again made big news,
159
459000
1936
當然，又造成了一次大新聞，
07:52
including now a retraction
160
460960
1616
包含現在
07:54
of a publication
from the journal "Nature."
from the journal "Nature."
161
462600
2840
被" 自然期刊 "撤銷發表的文章
所以，即使是最頂尖的數據分析公司，
Amazon和Google，
Amazon和Google，
07:58
So even the most data-savvy companies,
Amazon and Google,
Amazon and Google,
162
466480
3336
08:01
they sometimes get it wrong.
163
469840
2136
他們有時也會出錯。
08:04
And despite all those failures,
164
472000
2936
但儘管有這些失敗，
08:06
data is moving rapidly
into real-life decision-making --
into real-life decision-making --
165
474960
3856
數據正快速地進入我們
實際生活上的決策、
實際生活上的決策、
08:10
into the workplace,
166
478840
1816
進入工作職場、
08:12
law enforcement,
167
480680
1816
法律執行、
08:14
medicine.
168
482520
1200
醫藥界。
所以，我們應該確保數據是有幫助的。
08:16
So we should better make sure
that data is helping.
that data is helping.
169
484400
3336
08:19
Now, personally I've seen
a lot of this struggle with data myself,
a lot of this struggle with data myself,
170
487760
3136
我個人已經經歷過很多
自己在數據上的掙扎，
自己在數據上的掙扎，
08:22
because I work in computational genetics,
171
490920
1976
因為我在計算遺傳學界工作，
08:24
which is also a field
where lots of very smart people
where lots of very smart people
172
492920
2496
這個領域有很多非常聰明的人
08:27
are using unimaginable amounts of data
to make pretty serious decisions
to make pretty serious decisions
173
495440
3656
使用多到難以想像的數據
來制定相當嚴肅的決策，
來制定相當嚴肅的決策，
08:31
like deciding on a cancer therapy
or developing a drug.
or developing a drug.
174
499120
3560
像是癌症治療決策或藥物開發。
經過這幾年，我已經注意到一種模式
08:35
And over the years,
I've noticed a sort of pattern
I've noticed a sort of pattern
175
503520
2376
08:37
or kind of rule, if you will,
about the difference
about the difference
176
505920
2456
或者規則，如果你要這麼說也行，
08:40
between successful
decision-making with data
decision-making with data
177
508400
2696
就是有關於用數據做出
08:43
and unsuccessful decision-making,
178
511120
1616
成功決策和不成功決策，
08:44
and I find this a pattern worth sharing,
and it goes something like this.
and it goes something like this.
179
512760
3880
我發現這個模式值得分享，
它是這樣的......
它是這樣的......
當你要解決一個複雜問題時，
08:50
So whenever you're
solving a complex problem,
solving a complex problem,
180
518520
2135
08:52
you're doing essentially two things.
181
520679
1737
本質上你會做兩件事，
08:54
The first one is, you take that problem
apart into its bits and pieces
apart into its bits and pieces
182
522440
3296
第一件事是，你會把問題拆分得很仔細，
08:57
so that you can deeply analyze
those bits and pieces,
those bits and pieces,
183
525760
2496
所以你可以深度地分析這些細節，
09:00
and then of course
you do the second part.
you do the second part.
184
528280
2016
當然你的第二件事就是，
09:02
You put all of these bits and pieces
back together again
back together again
185
530320
2656
你會再把這些細節拿回來整合一起，
09:05
to come to your conclusion.
186
533000
1336
來得出你要的結論。
09:06
And sometimes you
have to do it over again,
have to do it over again,
187
534360
2336
有時候你必須一做再做，
09:08
but it's always those two things:
188
536720
1656
就這兩件事：
09:10
taking apart and putting
back together again.
back together again.
189
538400
2320
拆分、再合併一起。
但，關鍵是
09:14
And now the crucial thing is
190
542280
1616
09:15
that data and data analysis
191
543920
2896
數據與數據分析
09:18
is only good for the first part.
192
546840
2496
只適用於第一步驟，
09:21
Data and data analysis,
no matter how powerful,
no matter how powerful,
193
549360
2216
無論數據與數據分析多麼地強大，
09:23
can only help you taking a problem apart
and understanding its pieces.
and understanding its pieces.
194
551600
4456
它只能幫助你拆分問題及了解細節，
09:28
It's not suited to put those pieces
back together again
back together again
195
556080
3496
它不適用於把細節
拿回來放在一起再整合，
拿回來放在一起再整合，
09:31
and then to come to a conclusion.
196
559600
1896
來得出一個結論。
09:33
There's another tool that can do that,
and we all have it,
and we all have it,
197
561520
2736
有一個工具可以這麼做，
而我們都擁有它，
而我們都擁有它，
09:36
and that tool is the brain.
198
564280
1296
那工具就是大腦。
09:37
If there's one thing a brain is good at,
199
565600
1936
如果要說大腦有一項能力很強，
09:39
it's taking bits and pieces
back together again,
back together again,
200
567560
2256
那就是，它很會把事情
拆分細節後再整合一起，
拆分細節後再整合一起，
09:41
even when you have incomplete information,
201
569840
2016
即使當你有的只是不完整的資訊，
09:43
and coming to a good conclusion,
202
571880
1576
也能得到一個好的決策，
09:45
especially if it's the brain of an expert.
203
573480
2936
特別是專家的大腦。
09:48
And that's why I believe
that Netflix was so successful,
that Netflix was so successful,
204
576440
2656
而這也是為什麼我相信
Netflix會這麼成功的原因，
Netflix會這麼成功的原因，
09:51
because they used data and brains
where they belong in the process.
where they belong in the process.
205
579120
3576
因為他們在過程中使用數據與大腦。
09:54
They use data to first understand
lots of pieces about their audience
lots of pieces about their audience
206
582720
3536
他們利用數據，
首先了解很多觀眾的細節，
首先了解很多觀眾的細節，
09:58
that they otherwise wouldn't have
been able to understand at that depth,
been able to understand at that depth,
207
586280
3416
否則沒有這些數據，
他們沒有能力可以了解這麼深，
他們沒有能力可以了解這麼深，
10:01
but then the decision
to take all these bits and pieces
to take all these bits and pieces
208
589720
2616
但做出拆分、整合
及製作" 紙牌屋 "的
10:04
and put them back together again
and make a show like "House of Cards,"
and make a show like "House of Cards,"
209
592360
3336
這兩個決策，是數據中無法幫你決定的。
10:07
that was nowhere in the data.
210
595720
1416
10:09
Ted Sarandos and his team
made that decision to license that show,
made that decision to license that show,
211
597160
3976
Ted Sarandos和他的團隊做出
許可該節目的這個決策，
許可該節目的這個決策，
10:13
which also meant, by the way,
that they were taking
that they were taking
212
601160
2381
總之，意思就是，
他們在做出決策當下，
也正在承擔很大的個人風險。
也正在承擔很大的個人風險。
10:15
a pretty big personal risk
with that decision.
with that decision.
213
603565
2851
10:18
And Amazon, on the other hand,
they did it the wrong way around.
they did it the wrong way around.
214
606440
3016
而另一方面，Amazon他們把它搞砸了。
10:21
They used data all the way
to drive their decision-making,
to drive their decision-making,
215
609480
2736
他們全程依賴數據來制定決策，
10:24
first when they held
their competition of TV ideas,
their competition of TV ideas,
216
612240
2416
首先，他們舉辦節目想法的競賽，
10:26
then when they selected "Alpha House"
to make as a show.
to make as a show.
217
614680
3696
然後當他們選擇" 艾爾發屋 "來作為節目，
10:30
Which of course was
a very safe decision for them,
a very safe decision for them,
218
618400
2496
當然啦，對他們而言，
這是一個非常安全的決策，
這是一個非常安全的決策，
10:32
because they could always
point at the data, saying,
point at the data, saying,
219
620920
2456
因為他們總是可以指著數據說，
10:35
"This is what the data tells us."
220
623400
1696
＂這是數據告訴我們的＂
10:37
But it didn't lead to the exceptional
results that they were hoping for.
results that they were hoping for.
221
625120
4240
但這並沒有帶領他們到
他們所希望的傑出結果。
他們所希望的傑出結果。
所以，數據當然是做決策時的
一個強大的工具，
一個強大的工具，
10:42
So data is of course a massively
useful tool to make better decisions,
useful tool to make better decisions,
222
630120
4976
10:47
but I believe that things go wrong
223
635120
2376
但我相信，當數據開始主導這些決策時，
10:49
when data is starting
to drive those decisions.
to drive those decisions.
224
637520
2576
事情也會開始出錯。
10:52
No matter how powerful,
data is just a tool,
data is just a tool,
225
640120
3776
不管它有多麼的強大，
數據僅是一個工具，
數據僅是一個工具，
10:55
and to keep that in mind,
I find this device here quite useful.
I find this device here quite useful.
226
643920
3336
並把這個記在腦裡，
我發現這個裝置相當有用。
我發現這個裝置相當有用。
你們很多人將會 ...
10:59
Many of you will ...
227
647280
1216
11:00
(Laughter)
228
648520
1216
（笑聲）
11:01
Before there was data,
229
649760
1216
在有數據之前，
11:03
this was the decision-making
device to use.
device to use.
230
651000
2856
這就是用來做決策的工具
11:05
(Laughter)
231
653880
1256
（笑聲）
11:07
Many of you will know this.
232
655160
1336
你們很多人應該知道這個玩意。
11:08
This toy here is called the Magic 8 Ball,
233
656520
1953
這個玩具在這裡稱做＂魔術 8號球＂，
11:10
and it's really amazing,
234
658497
1199
它真的很奇妙，
11:11
because if you have a decision to make,
a yes or no question,
a yes or no question,
235
659720
2896
因為如果你要做一個
＂是或不是＂的決策時，
＂是或不是＂的決策時，
11:14
all you have to do is you shake the ball,
and then you get an answer --
and then you get an answer --
236
662640
3736
你只要搖一搖這顆球，
然後你就可以得到答案了--
然後你就可以得到答案了--
11:18
"Most Likely" -- right here
in this window in real time.
in this window in real time.
237
666400
2816
＂很有可能是＂--
就在這視窗裡及時顯現給你看，
就在這視窗裡及時顯現給你看，
11:21
I'll have it out later for tech demos.
238
669240
2096
我會帶它去做技術示範。
11:23
(Laughter)
239
671360
1216
（笑聲）
11:24
Now, the thing is, of course --
so I've made some decisions in my life
so I've made some decisions in my life
240
672600
3576
事情是，當然啦 --
我已經在我人生中做出一些決定，
我已經在我人生中做出一些決定，
11:28
where, in hindsight,
I should have just listened to the ball.
I should have just listened to the ball.
241
676200
2896
但早知道，我就應該聽這顆球的話。
11:31
But, you know, of course,
if you have the data available,
if you have the data available,
242
679120
3336
但，當然，如果你有有效的數據，
11:34
you want to replace this with something
much more sophisticated,
much more sophisticated,
243
682480
3056
你想要用超複雜的方式來取代這顆球，
11:37
like data analysis
to come to a better decision.
to come to a better decision.
244
685560
3616
例如，用數據分析來得到更好的決策。
11:41
But that does not change the basic setup.
245
689200
2616
但這無法改變基本的設定，
11:43
So the ball may get smarter
and smarter and smarter,
and smarter and smarter,
246
691840
3176
所以這球會越來越聰明，
11:47
but I believe it's still on us
to make the decisions
to make the decisions
247
695040
2816
但我相信，如果我們想達成某些
曲線右邊末端的非凡成就，
曲線右邊末端的非凡成就，
11:49
if we want to achieve
something extraordinary,
something extraordinary,
248
697880
3016
最後我們自己還是得做出決定，
11:52
on the right end of the curve.
249
700920
1936
11:54
And I find that a very encouraging
message, in fact,
message, in fact,
250
702880
4496
事實上，我發現
一個非常激勵人心的訊息，
一個非常激勵人心的訊息，
11:59
that even in the face
of huge amounts of data,

ABOUT THE SPEAKER
Sebastian Wernicke - Data scientistAfter making a splash in the field of bioinformatics, Sebastian Wernicke moved on to the corporate sphere, where he motivates and manages multidimensional projects.
Why you should listen
Dr. Sebastian Wernicke is the Chief Data Scientist of ONE LOGIC, a data science boutique that supports organizations across industries to make sense of their vast data collections to improve operations and gain strategic advantages. Wernicke originally studied bioinformatics and previously led the strategy and growth of Seven Bridges Genomics, a Cambridge-based startup that builds platforms for genetic analysis.
Before his career in statistics began, Wernicke worked stints as both a paramedic and successful short animated filmmaker. He's also the author of the TEDPad app, an irreverent tool for creating an infinite number of "amazing and really bad" and mostly completely meaningless talks. He's the author of the statistically authoritative and yet completely ridiculous "How to Give the Perfect TEDTalk."
