ABOUT THE SPEAKER
Matt Killingsworth - Happiness researcher
Researcher Matt Killingsworth designs studies that gather data on happiness. One takeaway? "A Wandering Mind Is an Unhappy Mind."

Why you should listen

While doing his PhD research with Dan Gilbert at Harvard, Matt Killingsworth invented a nifty tool for investigating happiness: an iPhone app called Track Your Happiness that captured feelings in real time. (Basically, it pings you at random times and asks: How are you feeling right now, and what are you doing?) Data captured from the study became the landmark paper "A Wandering Mind Is an Unhappy Mind" (PDF). 

As an undergrad, Killingsworth studied economics and engineering, and worked for a few years as a software product manager -- an experience during which, he says, "I began to question my assumptions about what defined success for an individual, an organization, or a society." He's now a Robert Wood Johnson Health and Society Scholar examining such topics as "the relationship between happiness and the content of everyday experiences, the percentage of everyday experiences that are intrinsically valuable, and the degree of congruence between the causes of momentary happiness and of one’s overall satisfaction with life."

Matt Killingsworth: Want to be happier? Stay in the moment

When are humans most happy? To gather data on this question, Matt Killingsworth built an app, Track Your Happiness, that let people report their feelings in real time. Among the surprising results: We're often happiest when we're lost in the moment. And the flip side: The more our mind wanders, the less happy we can be.

So, people want a lot of things out of life,
0
944
2622
00:19
but I think, more than anything else, they want happiness.
1
3566
3895
00:23
Aristotle called happiness "the chief good," the end
2
7461
3328
00:26
towards which all other things aim.
3
10789
3272
00:29
According to this view, the reason we want a big house
4
14061
5520
00:35
or a nice car
5
19581
2633
00:38
or a good job
6
22214
2080
00:40
isn't that these things are intrinsically valuable.
7
24294
2448
00:42
It's that we expect them to bring us
8
26742
2518
00:45
happiness.
9
29260
1457
00:46
Now in the last 50 years, we Americans have gotten
10
30717
2632
00:49
a lot of the things that we want. We're richer.
11
33349
2027
00:51
We live longer. We have access to technology
12
35376
3077
00:54
that would have seemed like science fiction
13
38453
2167
00:56
just a few years ago.
14
40620
2241
00:58
The paradox of happiness is that even though the
15
42861
2424
01:01
objective conditions of our lives have improved dramatically,
16
45285
2902
01:04
we haven't actually gotten any happier.
17
48187
3564
01:07
Maybe because these conventional notions of progress
18
51751
2919
01:10
haven't delivered big benefits in terms of happiness,
19
54670
2476
01:13
there's been an increased interest in recent years
20
57146
2130
01:15
in happiness itself.
21
59276
2522
01:17
People have been debating the causes of happiness
22
61798
2035
01:19
for a really long time, in fact for thousands of years,
23
63833
2599
01:22
but it seems like many of those debates remain unresolved.
24
66432
3457
01:25
Well, as with many other domains in life, I think
25
69889
2059
01:27
the scientific method has the potential to answer this question.
26
71948
3212
01:31
In fact, in the last few years, there's been an explosion
27
75160
2534
01:33
in research on happiness. For example, we've learned a lot
28
77694
2801
01:36
about its demographics, how things like income
29
80495
3112
01:39
and education, gender and marriage relate to it.
30
83607
3426
01:42
But one of the puzzles this has revealed is that
31
87033
2222
01:45
factors like these don't seem to have a particularly strong effect.
32
89255
2939
01:48
Yes, it's better to make more money rather than less,
33
92194
2437
01:50
or to graduate from college instead of dropping out,
34
94631
2712
01:53
but the differences in happiness tend to be small.
35
97343
2761
01:56
Which leaves the question, what are the big causes of happiness?
36
100104
3835
01:59
I think that's a question we haven't really answered yet,
37
103939
2697
02:02
but I think something that has the potential to be an answer
38
106636
2712
02:05
is that maybe happiness has an awful lot to do with
39
109348
2721
02:07
the contents of our moment-to-moment experiences.
40
112069
2444
02:10
It certainly seems that we're going about our lives,
41
114513
1995
02:12
that what we're doing, who we're with, what we're thinking about,
42
116508
3935
02:16
have a big influence on our happiness, and yet
43
120443
2352
02:18
these are the very factors that have been very difficult,
44
122795
2233
02:20
in fact almost impossible, for scientists to study.
45
125028
2387
02:23
A few years ago, I came up with a way to study people's happiness
46
127415
3061
02:26
moment to moment as they're going about their daily lives
47
130476
2579
02:28
on a massive scale all over the world, something we'd never
48
133055
2742
02:31
been able to do before. Called trackyourhappiness.org,
49
135797
2791
02:34
it uses the iPhone to monitor people's happiness in real time.
50
138588
4286
02:38
How does this work? Basically, I send people signals
51
142874
2789
02:41
at random points throughout the day, and then I ask them
52
145663
2440
02:44
a bunch of questions about their moment-to-moment experience
53
148103
2288
02:46
at the instant just before the signal.
54
150391
2534
02:48
The idea is that, if we can watch how people's happiness
55
152925
2807
02:51
goes up and down over the course of the day,
56
155732
2624
02:54
minute to minute in some cases,
57
158356
1728
02:55
and try to understand how what people are doing,
58
160084
2142
02:58
who they're with, what they're thinking about, and all
59
162226
2843
03:00
the other factors that describe our day, how those might
60
165069
2176
03:03
relate to those changes in happiness, we might be able
61
167245
2711
03:05
to discover some of the things that really have
62
169956
1546
03:07
a big influence on happiness.
63
171502
2305
03:09
We've been fortunate with this project to collect
64
173807
2306
03:12
quite a lot of data, a lot more data of this kind than I think
65
176113
2858
03:14
has ever been collected before,
66
178971
1859
03:16
over 650,000 real-time reports
67
180830
3221
03:19
from over 15,000 people.
68
184051
2879
03:22
And it's not just a lot of people, it's a really diverse group,
69
186930
3109
03:25
people from a wide range of ages, from 18 to late 80s,
70
190039
3487
03:29
a wide range of incomes, education levels,
71
193526
2928
03:32
people who are married, divorced, widowed, etc.
72
196454
3063
03:35
They collectively represent every one of
73
199517
2264
03:37
86 occupational categories and hail from over 80 countries.
74
201781
4861
03:42
What I'd like to do with the rest of my time with you today
75
206642
2902
03:45
is talk a little bit about one of the areas that we've been
76
209544
2129
03:47
investigating, and that's mind-wandering.
77
211673
3183
03:50
As human beings, we have this unique ability
78
214856
2400
03:53
to have our minds stray away from the present.
79
217256
2935
03:56
This guy is sitting here working on his computer,
80
220191
1925
03:58
and yet he could be thinking about
81
222116
1054
03:59
the vacation he had last month,
82
223170
2689
04:01
wondering what he's going to have for dinner.
83
225859
1963
04:03
Maybe he's worried that he's going bald. (Laughter)
84
227822
3833
04:07
This ability to focus our attention on something other
85
231655
2785
04:10
than the present is really amazing. It allows us to learn
86
234440
3255
04:13
and plan and reason in ways that no other species of animal can.
87
237695
4494
04:18
And yet it's not clear what the relationship is
88
242189
2398
04:20
between our use of this ability and our happiness.
89
244587
3916
04:24
You've probably heard people suggest that you should
90
248503
1858
04:26
stay focused on the present. "Be here now,"
91
250361
2491
04:28
you've probably heard a hundred times.
92
252852
1485
04:30
Maybe, to really be happy, we need to stay completely
93
254337
2681
04:32
immersed and focused on our experience in the moment.
94
257018
3511
04:36
Maybe these people are right. Maybe mind-wandering
95
260529
1834
04:38
is a bad thing.
96
262363
1730
04:39
On the other hand, when our minds wander,
97
264093
2419
04:42
they're unconstrained. We can't change the physical reality
98
266512
2661
04:45
in front of us, but we can go anywhere in our minds.
99
269173
3388
04:48
Since we know people want to be happy, maybe
100
272561
1813
04:50
when our minds wander, they're going to someplace happier than the place
101
274374
2691
04:52
that they're leaving. It would make a lot of sense.
102
277065
2233
04:55
In other words, maybe the pleasures of the mind
103
279298
1498
04:56
allow us to increase our happiness with mind-wandering.
104
280796
4426
05:01
Well, since I'm a scientist, I'd like to try to
105
285222
2011
05:03
resolve this debate with some data, and in particular
106
287233
2677
05:05
I'd like to present some data to you from three questions
107
289910
2488
05:08
that I ask with Track Your Happiness. Remember, this is from
108
292398
2210
05:10
sort of moment-to-moment experience in people's real lives.
109
294608
2652
05:13
There are three questions. The first one is a happiness question:
110
297260
3030
05:16
How do you feel, on a scale ranging from very bad
111
300290
2875
05:19
to very good? Second, an activity question:
112
303165
4139
05:23
What are you doing, on a list of 22 different activities
113
307304
2528
05:25
including things like eating and working and watching TV?
114
309832
3225
05:28
And finally a mind-wandering question:
115
313057
3588
05:32
Are you thinking about something other
116
316645
2642
05:35
than what you're currently doing?
117
319287
2623
05:37
People could say no -- in other words, I'm focused only on my task --
118
321910
3442
05:41
or yes -- I am thinking about something else --
119
325352
2529
05:43
and the topic of those thoughts are pleasant,
120
327881
2456
05:46
neutral or unpleasant.
121
330337
1426
05:47
Any of those yes responses are what we called mind-wandering.
122
331763
5459
05:53
So what did we find?
123
337222
2465
05:55
This graph shows happiness on the vertical axis,
124
339687
2299
05:57
and you can see that bar there representing how happy
125
341986
2240
06:00
people are when they're focused on the present,
126
344226
1333
06:01
when they're not mind-wandering.
127
345559
1923
06:03
As it turns out, people are substantially less happy
128
347482
3719
06:07
when their minds are wandering than when they're not.
129
351201
4736
06:11
Now you might look at this result and say, okay, sure,
130
355937
2602
06:14
on average people are less happy when they're mind-wandering,
131
358539
2422
06:16
but surely when their minds are straying away
132
360961
1668
06:18
from something that wasn't very enjoyable to begin with,
133
362629
2119
06:20
at least then mind-wandering should be doing something good for us.
134
364748
3764
06:24
Nope. As it turns out,
135
368512
2699
06:27
people are less happy when they're mind-wandering
136
371211
1692
06:28
no matter what they're doing. For example,
137
372903
3026
06:31
people don't really like commuting to work very much.
138
375929
2177
06:34
It's one of their least enjoyable activities, and yet
139
378106
2760
06:36
they are substantially happier when they're focused
140
380866
2534
06:39
only on their commute than when their mind is going
141
383400
2362
06:41
off to something else.
142
385762
3047
06:44
It's amazing.
143
388809
1782
06:46
So how could this be happening? I think part of the reason,
144
390591
3845
06:50
a big part of the reason, is that when our minds wander,
145
394436
2398
06:52
we often think about unpleasant things, and they are
146
396834
2856
06:55
enormously less happy when they do that,
147
399690
3607
06:59
our worries, our anxieties, our regrets,
148
403297
2665
07:01
and yet even when people are thinking about something
149
405962
2960
07:04
neutral, they're still considerably less happy
150
408922
2864
07:07
than when they're not mind-wandering at all.
151
411786
1977
07:09
Even when they're thinking about something they would describe as pleasant,
152
413763
2835
07:12
they're actually just slightly less happy
153
416598
2204
07:14
than when they aren't mind-wandering.
154
418802
3257
07:17
If mind-wandering were a slot machine, it would be like
155
422059
2062
07:20
having the chance to lose 50 dollars, 20 dollars
156
424121
3033
07:23
or one dollar. Right? You'd never want to play. (Laughter)
157
427154
6151
07:29
So I've been talking about this, suggesting, perhaps,
158
433305
2673
07:31
that mind-wandering causes unhappiness, but all
159
435978
2812
07:34
I've really shown you is that these two things are correlated.
160
438790
2767
07:37
It's possible that's the case, but it might also be the case
161
441557
2785
07:40
that when people are unhappy, then they mind-wander.
162
444342
2454
07:42
Maybe that's what's really going on. How could we ever
163
446796
2369
07:45
disentangle these two possibilites?
164
449165
3089
07:48
Well, one fact that we can take advantage of, I think a fact
165
452254
2344
07:50
you'll all agree is true, is that time goes forward, not
166
454598
2957
07:53
backward. Right? The cause has to come before the effect.
167
457555
3997
07:57
We're lucky in this data we have many responses from each person,
168
461552
3430
08:00
and so we can look and see, does mind-wandering
169
464982
3196
08:04
tend to precede unhappiness, or does unhappiness
170
468178
2493
08:06
tend to precede mind-wandering, to get some insight
171
470671
2183
08:08
into the causal direction.
172
472854
2161
08:10
As it turns out, there is a strong relationship between
173
475015
3209
08:14
mind-wandering now and being unhappy a short time later,
174
478224
3685
08:17
consistent with the idea that mind-wandering is causing people to be unhappy.
175
481909
3719
08:21
In contrast, there's no relationship between being unhappy
176
485628
3160
08:24
now and mind-wandering a short time later.
177
488788
3009
08:27
In other words, mind-wandering very likely seems to be
178
491797
2322
08:30
an actual cause, and not merely a consequence, of unhappiness.
179
494119
5840
08:35
A few minutes ago, I likened mind-wandering
180
499959
2224
08:38
to a slot machine you'd never want to play.
181
502183
2263
08:40
Well, how often do people's minds wander?
182

Turns out, they wander a lot. In fact, really a lot.
183
506750
4457
08:47
Forty-seven percent of the time, people are thinking
184
511207
2694
08:49
about something other than what they're currently doing.
185
513901
3407
08:53
How does that depend on what people are doing?
186
517308
2438
08:55
This shows the rate of mind-wandering across 22 activities
187
519746
2753
08:58
ranging from a high of 65 percent — (Laughter) —
188
522499
3999
09:02
when people are taking a shower, brushing their teeth,
189
526498
2512
09:04
to 50 percent when they're working,
190
529010
2901
09:07
to 40 percent when they're exercising,
191
531911
3043
09:10
all the way down to this one short bar on the right
192
534954
1919
09:12
that I think some of you are probably laughing at.
193
536873
1988
09:14
Ten percent of the time people's minds are wandering
194
538861
2390
09:17
when they're having sex. (Laughter)
195
541251
4571
09:21
But there's something I think that's quite interesting in this graph,
196
545822
2933
09:24
and that is, basically with one exception,
197
548755
3048
09:27
no matter what people are doing, they're mind-wandering
198
551803
2178
09:29
at least 30 percent of the time, which suggests, I think,
199
553981
3678
09:33
that mind-wandering isn't just frequent, it's ubiquitous.
200
557659
2831
09:36
It pervades basically everything that we do.
201
560490
3733
09:40
In my talk today, I've told you a little bit about mind-wandering,
202
564223
3196
09:43
a variable that I think turns out to be fairly important
203
567419
2050
09:45
in the equation for happiness.
204
569469
1656
09:47
My hope is that over time, by tracking people's
205
571125
2015
09:49
moment-to-moment happiness and their experiences
206
573140
3048
09:52
in daily life, we'll be able to uncover a lot of important causes of happiness,
207
576188
3402
09:55
and then in the end, a scientific understanding of happiness
208
579590
2930
09:58
will help us create a future that's not only richer
209
582520
2697
10:01
and healthier, but happier as well.
210
585217

10:03
Thank you. (Applause)

ABOUT THE SPEAKER
Matt Killingsworth - Happiness researcher
Researcher Matt Killingsworth designs studies that gather data on happiness. One takeaway? "A Wandering Mind Is an Unhappy Mind."

Why you should listen

While doing his PhD research with Dan Gilbert at Harvard, Matt Killingsworth invented a nifty tool for investigating happiness: an iPhone app called Track Your Happiness that captured feelings in real time. (Basically, it pings you at random times and asks: How are you feeling right now, and what are you doing?) Data captured from the study became the landmark paper "A Wandering Mind Is an Unhappy Mind" (PDF). 

As an undergrad, Killingsworth studied economics and engineering, and worked for a few years as a software product manager -- an experience during which, he says, "I began to question my assumptions about what defined success for an individual, an organization, or a society." He's now a Robert Wood Johnson Health and Society Scholar examining such topics as "the relationship between happiness and the content of everyday experiences, the percentage of everyday experiences that are intrinsically valuable, and the degree of congruence between the causes of momentary happiness and of one’s overall satisfaction with life."
