Do you ever feel completely overwhelmed

2000
當你面對著一個複雜的問題時
00:17
when you're faced with a complex problem?
1
2000
3000
你是否曾經覺得很不知所措？
00:20
Well, I hope to change that in less than three minutes.
2
5000
3000
我希望能在三分鐘內為此做些改變
00:23
So, I hope to convince you that complex
3
8000
2000
因此，我希望說服你其實複雜
00:25
doesn't always equal complicated.
4
10000
2000
並不總是繁雜
00:27
So for me, a well-crafted baguette, fresh out of the oven,
5
12000
3000
對我來說，一個剛出爐的精心烘培法國麵包
00:30
is complex,
6
15000
2000
是複雜的
00:32
but a curry onion green olive poppy cheese bread
7
17000
2000
但是咖哩綠橄欖罌粟洋蔥起司麵包
00:34
is complicated.
8
19000
3000
是複雜的
00:37
I'm an ecologist, and I study complexity. I love complexity.
9
22000
3000
我是一個生態學家，我研究複雜性，我愛複雜性
00:40
And I study that in the natural world, the interconnectedness of species.
10
25000
3000
我還研究在自然界中，物種彼此之間的關係
00:43
So here's a food web,
11
28000
2000
這是一個食物網
00:45
or a map of feeding links between species
12
30000
2000
或者是一張食物鏈關聯圖
00:47
that live in Alpine Lakes in the mountains of California.
13
32000
3000
描述加州高山湖的物種關係
00:50
And this is what happens to that food web
14
35000
2000
而這是食物網現在的樣子
00:52
when it's stocked with non-native fish that never lived there before.
15
37000
2000
非原生的魚類大量湧入後
00:54
All the grayed-out species disappear.
16
39000
2000
所有灰色的物種消失了
00:56
Some are actually on the brink of extinction.
17
41000
2000
有些瀕臨絕種
00:58
And lakes with fish have more mosquitos, even though they eat them.
18
43000
3000
有魚的湖會有更多蚊子，雖然魚會吃蚊子
01:01
These effects were all unanticipated,
19
46000
2000
這些影響都是預想不到的
01:03
and yet we're discovering they're predictable.
20
48000
2000
但我們發現他們是可被預測的
01:05
So I want to share with you a couple key insights
21
50000
2000
所以我想要分享幾個想法
01:07
about complexity we're learning from studying nature
22
52000
2000
關於在自然界學到的複雜性
01:09
that maybe are applicable to other problems.
23
54000
3000
或許可以沿用到其他問題
01:13
First is the simple power of good visualization tools
24
58000
2000
首先，視覺化工具所帶來的簡單力量
01:15
to help untangle complexity
25
60000
2000
可以幫助釐清複雜性
01:17
and just encourage you to ask questions you didn't think of before.
26
62000
3000
並且引導你思考你從未想過的問題
01:20
For example, you could plot the flow of carbon
27
65000
3000
例如，你可以在圖中找出相似處
01:23
through corporate supply chains in a corporate ecosystem,
28
68000
3000
在生態系統中的一堆關連中
01:26
or the interconnections of habitat patches
29
71000
2000
或在優勝美地國家公園
01:28
for endangered species in Yosemite National Park.
30
73000
3000
標出瀕絕物種棲息地的關係
01:31
The next thing is that if you want to predict
31
76000
2000
其次，如果你想要預測
01:33
the effect of one species on another,
32
78000
2000
物種間彼此的影響
01:35
if you focus only on that link,
33
80000
2000
如果你只專注那個連結
01:37
and then you black box the rest,
34
82000
2000
然後忽略掉其它的
01:39
it's actually less predictable
35
84000
2000
其實是較難預測的
01:41
than if you step back, consider the entire system -- all the species, all the links --
36
86000
3000
如果你退回上一步，納入整個系統，包括所有物種、關聯
01:44
and from that place,
37
89000
2000
從這裡
01:46
hone in on the sphere of influence that matters most.
38
91000
2000
把焦點集中在相關的影響範圍
01:48
And we're discovering, with our research,
39
93000
2000
而我們在研究中發現
01:50
that's often very local to the node you care about
40
95000
2000
通常是在你注意的癥結點附近的
01:52
within one or two degrees.
41
97000
2000
一到兩層左右
01:54
So the more you step back, embrace complexity,
42
99000
2000
所以你退的越多，並廣納複雜
01:56
the better chance you have of finding simple answers,
43
101000
2000
你就越有機會找到簡單的答案
01:58
and it's often different than the simple answer that you started with.
44
103000
3000
而且是和你起先著手的簡單答案不同
02:02
So let's switch gears and look at a really complex problem
45
107000
3000
現在換個角度，用美國政府來看
02:05
courtesy of the U.S. government.
46
110000
3000
真正複雜的問題
02:08
This is a diagram of the U.S. counterinsurgency strategy in Afghanistan.
47
113000
3000
這是美國對阿富汗鎮暴策略的示意圖
02:11
It was front page of the New York Times a couple months ago.
48
116000
3000
幾個月前出現在紐約時報頭版
02:14
Instantly ridiculed by the media
49
119000
2000
馬上被媒體嘲笑著
02:16
for being so crazy complicated.
50
121000
2000
因為這張表實在是太過複雜
02:18
And the stated goal was to increase popular support
51
123000
2000
而他們的目標是為了要聲援
02:20
for the Afghan government.
52
125000
2000
阿富汗政權
02:22
Clearly a complex problem,
53
127000
2000
這很明顯的是個多重的問題
02:24
but is it complicated?
54
129000
2000
但它複雜嗎
02:26
Well, when I saw this in the front page of the Times,
55
131000
2000
我看到報紙的這篇頭版時
02:28
I thought, "Great. Finally something I can relate to.
56
133000
2000
我心裡想著 "太好了，總算有類似的東西了"
02:30
I can sink my teeth into this."
57
135000
2000
"我可以拿出來大講特講"
02:32
So let's do it. So here we go for the first time ever,
58
137000
3000
來吧，全世界有史以來第一次
02:35
a world premiere view of this spaghetti diagram as an ordered network.
59
140000
3000
要把錯綜複雜的圖表變成有條理的網路
02:38
The circled node is the one we're trying to influence --
60
143000
2000
圈起來的癥結點是我們試圖想要去影響
02:40
popular support for the government.
61
145000
2000
對政府的支持聲浪
02:42
And so now we can look one degrees, two degrees,
62
147000
2000
因此，我們可以看，第一層，第二層
02:44
three degrees away from that node
63
149000
2000
第三層與結點間的關係
02:46
and eliminate three-quarters of the diagram outside that sphere of influence.
64
151000
3000
然後去除圖表中的四分之三沒有在範圍裡的影響
02:49
Within that sphere,
65
154000
2000
在這個範圍中
02:51
most of those nodes are not actionable, like the harshness of the terrain,
66
156000
3000
大部分的結點是不可動的，如險峻的地勢
02:54
and a very small minority are actual military actions.
67
159000
3000
少數是軍事行動
02:57
Most are non-violent and they fall into two broad categories:
68
162000
3000
大部分是非暴力的，並且可分為兩大類別
03:01
active engagement with ethnic rivalries and religious beliefs
69
166000
3000
道德抗爭與宗教信條的激烈交戰
03:04
and fair, transparent economic development
70
169000
2000
與公平、透明的經濟發展
03:06
and provisioning of services.
71
171000
2000
和糧食供應服務
03:08
I don't know about this, but this is what I can decipher from this diagram
72
173000
3000
我不知道這些是什麼，可是我能在24秒內
03:11
in 24 seconds.
73
176000
2000
分析出這些東西
03:13
When you see a diagram like this, I don't want you to be afraid.
74
178000
2000
當你看到一個像這樣的圖表，你不需要感到害怕
03:15
I want you to be excited. I want you to be relieved.
75
180000
3000
我要你覺得開心，感到鬆了一口氣
03:18
Because simple answers may emerge.
76
183000
2000
因為簡單的答案會浮現
03:20
We're discovering in nature that simplicity often lies
77
185000
2000
我們發現在自然界裡，複雜的反面
03:22
on the other side of complexity.
78
187000
2000
其實就是簡單
03:24
So for any problem, the more you can zoom out and embrace complexity,
79
189000
3000
所以對任何問題，你愈往後退，涵蓋複雜
03:27
the better chance you have of zooming in
80
192000
2000
你愈有機會可以聚焦
03:29
on the simple details that matter most.
81
194000
2000
在簡單並影響最鉅的細節上
03:31
Thank you.
82
196000
2000
感謝各位
03:33
(Applause)
83
198000
3000
(鼓掌)
