我們要如何讓人做更多的好事：去投票、做慈善、保育資源，或只是對其他人更友善些？麻省里工學院的研究科學家伊雷茲‧尤里分享了一張簡單的檢查清單，善用名譽的力量——或是我們想要被視為大方、仁慈，而不是自私的共同慾望——給大家動機去做利他的事。聽聽這場演說，了解一下在方法上做一點小小的改變，就能有效讓人行善。

When I first started
working on this problem,
working on this problem,
6
21040
2136
當我剛開始處理這個問題時，
00:35
I collaborated with a power company
7
23200
1896
我和一家電力公司合作，
招攬用戶參加一個為了預防停電，
00:37
to recruit customers for a program
that prevents blackouts

00:43
The program is based
on a tried-and-true technology.

10
31600
2616
該計畫是以「反復驗證有效」的
技術為基礎。
技術為基礎。
00:46
It's one the Obama
administration even called

11
34240
2376
歐巴馬政府甚至說它是：
00:48
"the cornerstone to modernizing
America's electrical grid."

12
36640
3120
「美國電力網路現代化的基石。」
00:52
But, like so many
great technological solutions,

13
40880

但是，和許多很棒的
技術解決方案一樣，
技術解決方案一樣，
00:56
it has a key weakness:
14
44400
1440
它也有一個致命的弱點：
00:59
people.
15
47760
1200
人。
01:01
People need to sign up.
16
49720
1240
要有人參加才行。
01:04
To try to get people to sign up,
the power company sent them a nice letter,
the power company sent them a nice letter,
17
52000
3536
為了要讓大家參加，電力公司
寄了文情並茂的信給他們，
寄了文情並茂的信給他們，
告訴他們這個計畫的所有益處，
01:07
told them about
all the program's benefits,
all the program's benefits,
18
55560
2016
01:09
and it asked them to call
into a hotline if they were interested.
into a hotline if they were interested.
19
57600
3056
請他們有興趣的話，
撥打熱線洽詢。
撥打熱線洽詢。
01:12
Those letters went out,
20
60680
1696
那些信寄出了，
01:14
but the phones, they were silent.
21
62400
2760
但電話響都沒響。
01:18
So when we got involved,
we suggested one small change.
we suggested one small change.
22
66080
2760
所以，當我們加入時，
我們建議做一個小改變。
我們建議做一個小改變。
01:21
Instead of that hotline,
23
69360
1896
不要用熱線，
01:23
we suggested that they use sign-up sheets
that they'd post near the mailboxes
that they'd post near the mailboxes
24
71280
4616
我們建議他們使用報名表，
張貼在他們大樓內的信箱附近。
01:27
in people's buildings.
25
75920
1240
01:30
This tripled participation.
26
78120
2760
這個做法讓參與率變為三倍。
01:35
Why?
27
83160
1200
為什麼？
01:37
Well, we all know people care deeply
about what others think of them,
about what others think of them,
28
85680
4216
我們知道人很在乎
別人對自己的看法，
別人對自己的看法，
01:41
that we try to be seen
as generous and kind,
as generous and kind,
29
89920
2656
大家都想被認為是大方善良的人，
01:44
and we try to avoid
being seen as selfish or a mooch.
being seen as selfish or a mooch.
30
92600
2720
避免被視為自私或遊手好閒的人。
不論我們是否有意識到，
01:48
Whether we are aware of it or not,
this is a big part of why people do good,
this is a big part of why people do good,
31
96120
4416
人會行善的理由
很大一部分就是這個因素，
很大一部分就是這個因素，
01:52
and so small changes that give people
more credit for doing good,
more credit for doing good,
32
100560
5216
所以，做點小改變
讓行善的人更有榮譽感，
讓行善的人更有榮譽感，
01:57
those changes can make
a really big difference.
a really big difference.
33
105800
2336
這些小改變能造成很大的不同。
02:00
Small changes like
switching from a hotline,
switching from a hotline,
34
108160
2896
像換掉熱線這樣的小改變，
02:03
where nobody will ever find out
about your good deed,
about your good deed,
35
111080
3016
從沒有人知道你做了好事，
02:06
to a sign-up sheet
36
114120
1736
到改為報名表之後，
02:07
where anyone who walks by
can see your name.
can see your name.
37
115880
3120
經過的人就能看見你的名字。
02:12
In our collaborations with governments,
nonprofits, companies,
nonprofits, companies,
38
120520
3176
我們和政府、
非營利機構、企業合作時，
非營利機構、企業合作時，
02:15
when we're trying to get people
to do more good,
to do more good,
39
123720
2816
如果我們試圖想讓大家做更多好事，
02:18
we harness the power of reputations.
40
126560
2400
我們會利用名譽的力量。
02:22
And we have a simple checklist for this.
41
130000
2376
對此，我們有個簡單的檢查清單。
02:24
And in fact, you already know
the first item on that checklist.
the first item on that checklist.
42
132400
3240
事實上，你們已經知道
清單上的第一項是什麼。
清單上的第一項是什麼。
02:28
It's to increase observability,
43
136960
2296
就是提高行善的能見度，
02:31
to make sure people find out
about good deeds.
about good deeds.
44
139280
2720
確保大家能看到這些善行。
02:35
Now, wait a minute, I know
some of you are probably thinking,
some of you are probably thinking,
45
143440
2896
等等，我知道在座有些人正在想，
人不可能會認為：「喔，
02:38
there's no way people here thought,
46
146360
1696
02:40
"Oh, well, now that
I'm getting credit for my good deed,
I'm getting credit for my good deed,
47
148080
2656
做好事就能居功，
那實在太值得了。」
那實在太值得了。」
02:42
now it's totally worth it."
48
150760
1336
02:44
And you're right.
49
152120
1456
的確如此。
02:45
Usually, people don't.
50
153600
1240
通常，人不會這樣想。
02:47
Rather, when they're making
decisions in private,
decisions in private,
51
155760
3056
反而是，當人們在私下做決策時，
02:50
they worry about their own problems,
52
158840
1736
他們傾向擔心自己的問題，
02:52
about what to put on the table for dinner
or how to pay their bills on time.
or how to pay their bills on time.
53
160600
4136
如擔心晚餐要準備什麼，
或是如何準時付帳單。
或是如何準時付帳單。
02:56
But, when we make
their decision more observable,
their decision more observable,
54
164760
3096
但，當我們讓他們的
決策具能見度提高時，
決策具能見度提高時，
02:59
they start to attend more
to the opportunity to do good.
to the opportunity to do good.
55
167880
3080
他們就會開始比較注意
有沒有機會做好事。
有沒有機會做好事。
03:03
In other words, what's
so powerful about our approach
so powerful about our approach
56
171760
2816
換言之，我們方法的強大之處，
03:06
is that it could turn on
people's existing desire to do good,
people's existing desire to do good,
57
174600
4856
就是它能夠啟動人
想做好事的既有慾望，
想做好事的既有慾望，
03:11
in this case, to help
to prevent a blackout.
to prevent a blackout.
58
179480
2080
在這個例子中，
好事就是預防停電。
好事就是預防停電。
再回來談談能見度。
03:15
Back to observability.
59
183160
1656
03:16
I want to give you another example.
60
184840
1856
我想要舉另一個例子。
03:18
This one is from a collaboration
61
186720
1736
這個例子是我們
和一間非營利機構合作，
和一間非營利機構合作，
03:20
with a nonprofit that gets out the vote,
62
188480
2376
讓大家出來投票，
03:22
and it does this by sending hundreds
of thousands of letters every election
of thousands of letters every election
63
190880
3576
該機構的做法是
每次選舉都寄發數十萬封信，
每次選舉都寄發數十萬封信，
03:26
in order to remind people and try
to motivate them to go to the polls.
to motivate them to go to the polls.
64
194480
3320
提醒並鼓勵大家去投票。
03:30
We suggested adding
the following sentence:
the following sentence:
65
198760
2160
我們建議加上下列句子：
03:34
"Someone may call you to find out
about your experience at the polls."
about your experience at the polls."
66
202440
3400
「您可能會接到電訪，
詢問此次投票的體驗。」
詢問此次投票的體驗。」
03:38
This sentence makes it feel
more observable when you go to the polls,
more observable when you go to the polls,
67
206520
3400
這個句子會讓你覺得
去投票能增加自己行善的能見度，
去投票能增加自己行善的能見度，
03:43
and it increased the effect
of the letter by 50 percent.
of the letter by 50 percent.
68
211040
3040
它讓寄信的效益增加了 50%。
03:48
Making the letter more effective reduced
the cost of getting an additional vote
the cost of getting an additional vote
69
216680
3736
寄信的效益變得更高，
也讓每多一個人投票所需的成本
也讓每多一個人投票所需的成本
從七十美金降到約四十美金。
03:52
from 70 dollars down to about 40 dollars.
70
220440
1960
03:55
Observability has been used to do things
71
223200
1936
「能見度」已被用在許多地方，
03:57
like get people
to donate blood more frequently
to donate blood more frequently
72
225160
2656
比如若要讓大家更常捐血，
03:59
by listing the names of donors
on local newsletters,
on local newsletters,
73
227840
2976
就在當地的報紙上
列出捐血者的名字，
列出捐血者的名字，
04:02
or to pay their taxes on time
74
230840
1640
或是若要讓大家準時繳稅，
04:05
by listing the names of delinquents
on a public website.
on a public website.
75
233440
2816
就把行為不良者的名字
公佈在公開網站上。
公佈在公開網站上。
04:08
(Laughter)
76
236280
1840
（笑聲）
04:12
What about this example?
77
240200
1200
那麼這個例子呢？
04:14
Toyota got hundreds of thousands of people
to buy a more fuel-efficient car
to buy a more fuel-efficient car
78
242560
4056
豐田汽車讓數十萬人
購買燃料效益更高的車，
購買燃料效益更高的車，
04:18
by making the Prius so unique ...
79
246640
3616
做法是讓 Prius 與眾不同……
04:22
(Laughter)
80
250280
1600
（笑聲）
04:24
that their good deed
was observable from a mile away.
was observable from a mile away.
81
252800
2680
他們的善行讓人
遠在一哩外就能看到。
遠在一哩外就能看到。
04:28
(Laughter)
82
256040
2816
（笑聲）
04:30
Alright, so observability is great,
83
258880
2375
好，所以能見度是很棒的，
04:33
but we all know, we've all seen
84
261279
3537
但我們都知道，我們都看過
04:36
people walk by an opportunity to do good.
85
264840
2160
大家無視於做好事的機會。
04:40
They'll see somebody
asking for money on the sidewalk
asking for money on the sidewalk
86
268080
3296
他們都有看見在人行道上乞討的人，
04:43
and they'll pull out their phones
and look really busy,
and look really busy,
87
271400
2616
而他們會拿出手機裝忙，
或是去博物館時，
他們會輕快地從捐款箱旁閃過。
他們會輕快地從捐款箱旁閃過。
04:46
or they'll go to the museum and they'll
waltz right on by the donation box.
waltz right on by the donation box.
88
274040
3560
04:50
Imagine it's the holiday season
89
278320
2096
想像現在是假日季節，
04:52
and you're going to the supermarket,
and there's a Salvation Army volunteer,
and there's a Salvation Army volunteer,
90
280440
3696
你要去超市，有個救世軍（慈善
組織）的志工在那裡搖著鈴鐺，
組織）的志工在那裡搖著鈴鐺，
04:56
and he's ringing his bell.
91
284160
1256
04:57
A few years ago, researchers in San Diego
92
285440
1976
幾年前，聖地牙哥的研究者
04:59
teamed up with a local chapter
from the Salvation Army
from the Salvation Army
93
287440
3456
和救世軍在當地的分會合作，
05:02
to try to find ways to increase donations.
94
290920
2200
試圖想辦法增加捐款。
05:06
What they found was kind of funny.
95
294240
1620
他們的發現還蠻有趣的。
05:08
When the volunteer
stood in front of just one door,
stood in front of just one door,
96
296680
2400
當志工只站在一扇門前時，
05:12
people would avoid giving
by going out the other door.
by going out the other door.
97
300040
2560
大家會走另一扇門，來避開捐款。
05:16
Why?
98
304880
1200
為什麼？
05:19
Well, because they can always claim,
"Oh, I didn't see the volunteer,"
"Oh, I didn't see the volunteer,"
99
307080
3696
因為他們可以宣稱：
「喔，我剛沒看到那位志工。」
「喔，我剛沒看到那位志工。」
05:22
or, "I wanted to get
something from over there,"
something from over there,"
100
310800
2256
或「我想要去那邊買東西。」
或「我的車在那一頭。」
05:25
or, "That's where my car is."
101
313080
1400
05:27
In other words, there's lots of excuses.
102
315560
1920
換言之，會有很多藉口。
05:30
And that brings us
to the second item on our checklist:
to the second item on our checklist:
103
318640
2976
那就帶出了檢查清單上的第二項：
05:33
to eliminate excuses.
104
321640
1720
消除藉口。
05:36
In the case of the Salvation Army,
105
324800
1656
以救世軍的例子來說，
05:38
eliminating excuses just means
standing in front of both doors,
standing in front of both doors,
106
326480
3256
消除藉口的方式
就是站在兩扇門的前面，
就是站在兩扇門的前面，
05:41
and sure enough, when they did this,
107
329760
2056
果真沒錯，當他們這麼做時，
05:43
donations rose.
108
331840
1200
捐款就提高了。
05:47
But that's when things got kind of funny,
109
335280
2176
但此時有趣的事發生了，
05:49
even funnier.
110
337480
1200
甚至更有趣。
05:51
The researchers
were out in the parking lot,
were out in the parking lot,
111
339960
2536
研究者在外頭的停車場，
05:54
and they were counting people
as they came in and out of the store,
as they came in and out of the store,
112
342520
3176
計算進出商店的人數，
05:57
and they noticed that when the volunteers
stood in front of both doors,
stood in front of both doors,
113
345720
3816
他們注意到，當志工
站在兩扇門的前面時，
站在兩扇門的前面時，
06:01
people stopped coming
out of the store at all.
out of the store at all.
114
349560
2176
就再也沒有人從商店走出來了。
06:03
(Laughter)
115
351760
3056
（笑聲）
06:06
Obviously, they were surprised by this,
so they decided to look into it further,
so they decided to look into it further,
116
354840
4136
顯然，他們很訝異這個發現，
所以他們決定要深究一下，
所以他們決定要深究一下，
06:11
and that's when they found that there
was actually a third, smaller utility door
was actually a third, smaller utility door
117
359000
5096
此時，他們發現
其實還有第三個較小的門，
06:16
usually used to take out the recycling --
118
364120
1976
通常是處理資源回收用的——
06:18
(Laughter)
119
366120
1536
（笑聲）
06:19
and now people were going out that door
in order to avoid the volunteers.
in order to avoid the volunteers.
120
367680
3496
現在大家會走那個小門，以避開志工。
06:23
(Laughter)
121
371200
2360
（笑聲）
06:26
This teaches us
an important lesson though.
an important lesson though.
122
374320
2320
不過，這教了我們很重要的一課。
06:30
When we're trying to eliminate excuses,
we need to be very thorough,
we need to be very thorough,
123
378480
3536
當我們試圖消除藉口時，
要消除得非常徹底，
要消除得非常徹底，
因為人在創造藉口方面
是非常有創意的。
是非常有創意的。
06:34
because people are
really creative in making them.
really creative in making them.
124
382040
2376
06:36
(Laughter)
125
384440
2200
（笑聲）
06:41
Alright, I want to switch to a setting
126
389760
1856
好，我想要換個情境，
06:43
where excuses can have
deadly consequences.
deadly consequences.
127
391640
2200
在這裡，藉口會有致命的後果。
06:48
What if I told you that the world's
deadliest infectious disease has a cure,
deadliest infectious disease has a cure,
128
396160
3720
如果我告訴各位，世界上
最致命的傳染病是有解藥的呢？
最致命的傳染病是有解藥的呢？
06:52
in fact, that it's had one for 70 years,
129
400960
2936
事實上，七十年前就有了解藥，
06:55
a good one, one that works
almost every time?
almost every time?
130
403920
2200
好的且通常每次見效的解藥。
06:59
It's incredible, but it's true.
131
407920
1560
這很不可思議，但這是真的。
07:02
The disease is tuberculosis.
132
410400
1976
我說的疾病是結核病。
07:04
It infects some 10 million people a year,
133
412400
2296
每年會有一千萬人受感染，
07:06
and it kills almost two million of them.
134
414720
2120
當中有近兩百萬人會因此而死。
07:09
Like the blackout prevention program,
we've got the solution.
we've got the solution.
135
417680
4056
就像預防停電計畫一樣，
我們也有解決方案。
我們也有解決方案。
07:13
The problem is people.
136
421760
1240
問題是在人。
07:16
People need to take their medication
137
424000
1736
患者必須吃藥
07:17
so that they're cured,
138
425760
1896
才能治癒，
07:19
and so that they don't
get other people sick.
get other people sick.
139
427680
2160
才不會傳染給其他人。
07:23
For a few years now,
we've been collaborating
we've been collaborating
140
431520
2136
這幾年，我們一直和一間
07:25
with a mobile health startup
called Keheala
called Keheala
141
433680
2296
行動健康新創公司 Keheala 合作，
07:28
to support TB patients
as they undergo treatment.
as they undergo treatment.
142
436000
2680
在結核病病人接受治療時支持他們。
07:31
Now, you have to understand,
TB treatment, it's really tough.
TB treatment, it's really tough.
143
439280
3096
你們要知道，結核病
治療是非常辛苦的。
治療是非常辛苦的。
07:34
We're talking about taking
a really strong antibiotic
a really strong antibiotic
144
442400
2576
我們在談的是要服用
非常強力的抗生素，
非常強力的抗生素，
07:37
every single day for six months or more.
145
445000
2336
每天都要服用，持續六個月以上。
07:39
That antibiotic is so strong
that it will make you feel sick.
that it will make you feel sick.
146
447360
2896
那種抗生素強到會讓你很不舒服。
會讓你作嘔、頭昏。
07:42
It will make you feel nauseous and dizzy.
147
450280
1976
會讓你的尿液變成奇怪的顏色。
07:44
It will make your pee turn funny colors.
148
452280
1920
07:46
It's also a problem because
you have to go back to the clinic
you have to go back to the clinic
149
454720
2896
還有一個問題是，
你幾乎每週都要回診一次，
你幾乎每週都要回診一次，
07:49
about every week
in order to get more pills,
in order to get more pills,
150
457640
2416
才能取得更多的藥，
07:52
and in sub-Saharan Africa
or other places where TB is common,
or other places where TB is common,
151
460080
3456
在撒哈拉以南非洲或是其他
常見到結核病的地方，
常見到結核病的地方，
07:55
now you're talking
about going someplace pretty far,
about going someplace pretty far,
152
463560
2456
診所是非常遙遠的，
07:58
taking tough and slow public transport,
153
466040
3016
要搭乘很難坐又緩慢的
大眾運輸工具，
大眾運輸工具，
08:01
maybe the clinic is inefficient.
154
469080
2056
也許診所還沒很效率。
這就表示每週要請
半天假不能工作，
半天假不能工作，
08:03
So now you're talking about taking
a half day off of work every week
a half day off of work every week
155
471160
3216
08:06
from a job you desperately
can't afford to lose.
can't afford to lose.
156
474400
2880
且這是你絕對不能丟的飯碗。
08:09
It's even worse when you consider the fact
that there's a terrible stigma,
that there's a terrible stigma,
157
477920
3496
更糟糕的是，這種疾病
還有著很不好的污名，
還有著很不好的污名，
你絕對不希望大家知道你有這種病。
08:13
and you desperately don't want people
to find that you have the disease.
to find that you have the disease.
158
481440
3416
08:16
Some of the toughest stories we hear
are actually from women
are actually from women
159
484880
2856
我們聽過最艱辛的故事，
其實是女性的故事，
其實是女性的故事，
08:19
who, in these places where
domestic violence can be kind of common,
domestic violence can be kind of common,
160
487760
3536
在這些家暴還蠻常見的地區，
08:23
they tell us that they have to
hide it from their husbands
hide it from their husbands
161
491320
2736
她們告訴我們，
她們不能讓先生知道
她們不能讓先生知道
08:26
that they're coming to the clinic.
162
494080
1640
她們要去診所。
08:29
So it's no surprise
that people don't complete treatment.
that people don't complete treatment.
163
497800
2800
並不意外，很多人沒有完成治療。
08:33
Can our approach really help them?
164
501840
2136
我們的方式能協助他們嗎？
08:36
Can we really get them to stick it out?
165
504000
1880
我們能讓他們撐到最後嗎？
08:40
Yeah.
166
508040
1200
可以。
08:42
Every day, we text patients
to remind them to take their medication,
to remind them to take their medication,
167
510080
4096
每天，我們都會
發簡訊提醒患者吃藥，
發簡訊提醒患者吃藥，
08:46
but if we stopped there,
168
514200
1536
但如果我們只做這樣，
病人會有很多藉口。
病人會有很多藉口。
08:47
there'd be lots of excuses.
169
515760
2056
08:49
"Well, I didn't see the text."
170
517840
1456
「嗯，我沒看到簡訊。」
08:51
Or, "You know, I saw the text,
but then I totally forgot,
but then I totally forgot,
171
519320
2695
或「我看到簡訊了，
但一會兒就全忘了，
但一會兒就全忘了，
08:54
put the phone down
and I just forgot about it."
and I just forgot about it."
172
522039
2217
一放下手機，我就忘個精光。」
08:56
Or, "I lent the phone out to my mom."
173
524280
1800
或「我把手機借給我媽了。」
08:59
We have to eliminate these excuses
174
527600
2016
我們得要消除這些藉口，
09:01
and we do that by asking patients
175
529640
2016
我們的做法是請病人
09:03
to log in and verify
that they've taken their medication.
that they've taken their medication.
176
531680
2960
登入並確認他們已經吃了藥。
09:07
If they don't log in, we text them again.
177
535680
2256
若他們沒登入，
我們就會再傳簡訊。
我們就會再傳簡訊。
09:09
If they don't log in,
we text them yet again.
we text them yet again.
178
537960
2096
若他們沒登入，
我們又會再傳簡訊。
我們又會再傳簡訊。
09:12
If, after three times,
they still haven't verified,
they still haven't verified,
179
540880
3216
如果三次之後他們還是沒有確認，
09:16
we notify a team of supporters
180
544120
1816
我們就會通知支持者團隊，
09:17
and that team will call and text them
181
545960
2256
該團隊會打電話和發簡訊給他們，
09:20
to try to get them back on the wagon.
182
548240
1800
試著讓他們回來繼續吃藥。
09:22
No excuses.
183
550960
1200
沒有藉口。
09:25
Our approach, which, admittedly,
uses all sorts of behavioral techniques,
uses all sorts of behavioral techniques,
184
553520
3776
無可否認，我們的方法
用上了各種行為技巧，
用上了各種行為技巧，
09:29
including, as you've
probably noticed, observability,
probably noticed, observability,
185
557320
3216
你們可能有注意到，
能見度也用上了，
能見度也用上了，
09:32
it was very effective.
186
560560
1240
它非常有效。
09:34
Patients without access to our platform
187
562800
2176
沒有使用我們平台的病人，
09:37
were three times more likely
not to complete treatment.
not to complete treatment.
188
565000
3160
最後沒有完成治療的機率有三倍高。
09:43
Alright,
189
571520
1376
好，
09:44
you've increased observability,
190
572920
1536
你已經增加了能見度，
你已經消除了藉口，
你已經消除了藉口，
09:46
you've eliminated excuses,
191
574480
2216
09:48
but there's still a third thing
you need to be aware of.
you need to be aware of.
192
576720
2640
但還有第三項你得要知道。
09:52
If you've been to Washington, DC
or Japan or London,
or Japan or London,
193
580800
3256
如果你去過華盛頓特區、日本或倫敦，
09:56
you know that metro riders there
194
584080
1696
你們會知道搭捷運的人
09:57
will be very careful to stand
on the right-hand side of the escalator
on the right-hand side of the escalator
195
585800
3456
都會注意要站在手扶梯的右側，
10:01
so that people can go by on the left.
196
589280
1920
左側供快速通行用。
10:04
But unfortunately,
not everywhere is that the norm,
not everywhere is that the norm,
197
592160
2376
但，可惜的是，
這規則並非放諸四海皆準，
這規則並非放諸四海皆準，
10:06
and there's plenty of places
where you can just stand on both sides
where you can just stand on both sides
198
594560
3176
在許多地方，兩側都可以站人，
而把手扶梯擋住了。
而把手扶梯擋住了。
10:09
and block the escalator.
199
597760
1256
很顯然，如果我們靠右站，
10:11
Obviously, it's better for others
200
599040
1616
10:12
when we stand on the right
and let them go by,
and let them go by,
201
600680
2296
左側讓需快速通過的人使用，
是利他的，
是利他的，
10:15
but we're only expected
to do that some places.
to do that some places.
202
603000
2720
但這只在某些地方我們才需這樣做。
10:18
This is a general phenomenon.
203
606720
1416
這現象很普遍。
10:20
Sometimes we're expected to do good
204
608160
2056
有時，我們被要求去做好事，
10:22
and sometimes not,
205
610240
1816
有時則沒有，
10:24
and it means that people
are really sensitive to cues
are really sensitive to cues
206
612080
3376
那就表示，大家對於特定情境中
10:27
that they're expected to do good
in a particular situation,
in a particular situation,
207
615480
2960
要去做好事的暗示是很敏感的，
10:31
which brings us to the third
and final item on our checklist:
and final item on our checklist:
208
619600
3696
這就帶出了檢查清單中的
第三項，也是最後一項：
第三項，也是最後一項：
10:35
to communicate expectations,
209
623320
1776
溝通表達期望，
10:37
to tell people,
210
625120
1416
要告訴別人：
10:38
"Do the good deed right now."
211
626560
2080
「做好事，且現在就做。」
10:42
Here's a simple way
to communicate expectations;
to communicate expectations;
212
630680
2256
溝通表達期望，有個簡單的方式；
10:44
simply tell them, "Hey, everybody else
is doing the good deed."
is doing the good deed."
213
632960
3176
簡單告訴他們：「嘿，
其他人都在做好的行為。」
其他人都在做好的行為。」
10:48
The company Opower
sends people in their electricity bill
sends people in their electricity bill
214
636160
4176
Opower 這間公司
在寄送電力帳單時，
在寄送電力帳單時，
10:52
a small insert that compares
their energy consumption
their energy consumption
215
640360
2776
會插入一張小單子，
將他們的能源消耗
將他們的能源消耗
10:55
with that of people
with similarly sized homes.
with similarly sized homes.
216
643160
3240
和其他房子大小類似的用戶做比較。
10:59
And when people find out that their
neighbors are using less electricity,
neighbors are using less electricity,
217
647000
3456
當大家發現他們的
鄰居用電比較少時，
鄰居用電比較少時，
他們就會開始減少消耗。
11:02
they start to consume less.
218
650480
1896
11:04
That same approach, it's been used
to get people to vote or give to charity
to get people to vote or give to charity
219
652400
3656
同樣的方式也曾用在
讓人去投票或做慈善，
讓人去投票或做慈善，
11:08
or even reuse their towels in hotels.
220
656080
2120
甚至讓客入重複使用飯店的毛巾。
11:12
What about this one?
221
660240
1200
這個例子呢？
11:14
Here's another way
to communicate expectations;
to communicate expectations;
222
662240
2496
還有一種溝通表達期望的方式；
11:16
simply do it by saying, "Do the good deed"
just at the right time.
just at the right time.
223
664760
4080
只要很簡單地在對的時間
說：「要做好事。」
說：「要做好事。」
11:23
What about this one?
224
671840
1200
這個例子呢？
11:26
This ticker reframes
225
674320
2616
這張圖是把「關燈」這個
11:28
the kind of mundane task
of turning off the lights
of turning off the lights
226
676960
2816
很平凡的任務重新表達，
11:31
and turns it instead
into an environmental contribution.
into an environmental contribution.
227
679800
2840
轉變成一種對環境的貢獻。
11:36
The bottom line is,
lots of different ways to do this,
lots of different ways to do this,
228
684320
2816
重點是，有各種方式可以做到，
有許多溝通表達期望的方式。
11:39
lots of ways to communicate expectations.
229
687160
2056
但不要忘記去做。
11:41
Just don't forget to do it.
230
689240
1286
11:43
And that's it.
231
691320
1296
就這樣。
11:44
That's our checklist.
232
692640
1200
這就是我們的檢查清單。
11:48
Many of you are working on problems
with important social consequences,
with important social consequences,
233
696440
4336
在座許多人致力於
處理重要的社會問題，
處理重要的社會問題，
11:52
and sometimes you might need
to motivate people to do more good.
to motivate people to do more good.
234
700800
3400
有時你得激勵大家去行更多的善。
11:57
The tools you learned today
can help you with this.
can help you with this.
235
705520
3016
今天你們學到的工具
能協助大家做到這件事。
能協助大家做到這件事。
12:00
And these tools, they don't require
that you raise additional funds
that you raise additional funds
236
708560
3176
而這些工具並不需要你額外募資，
12:03
or that you develop
any more fancy technologies.
any more fancy technologies.
237
711760
2896
也不用開發什麼很炫的技術。
12:06
They just require harnessing reputations
238
714680
2776
它們只需要懂得利用名譽，
12:09
by increasing observability,
eliminating excuses
eliminating excuses
239
717480
3416
做法就是增加能見度、消除藉口、
12:12
and communicating expectations.
240
720920
1600
以及溝通表達期望。
12:16
Thank you.

Why you should listen
Erez (pronounced ‘EH-rez’) Yoeli is a research scientist at MIT's Sloan School of Management, where he directs the Applied Cooperation Team. His research focuses on altruism: understanding how it works and how to promote it. He collaborates with governments, nonprofits and companies to apply these insights to address real-world challenges like increasing energy conservation, improving antibiotic adherence, reducing smoking in public places and promoting philanthropy.
Yoeli teaches the undergraduate Game Theory course at Harvard and regularly publishes theoretical and applied academic research articles. He shares his research highlights through frequent talks and featured articles in the New York Times, The Economist, Quartz and Behavioral Scientist. His research has also been profiled nationally and internationally in publications like TIME and Huffington Post.
Yoeli received his PhD in economics from the University of Chicago Booth School of Business. Before founding the Applied Cooperation Team, he was an economist at the US Federal Trade Commission and served as an expert witness in cases against companies that defrauded consumers. In an earlier, "pre-economist" life, he was a classical percussionist. He enjoys spicy food, hiking and spending time with his two very cuddly cats.
