-
How can we get people to do more good,
-
to go to the polls,
give to charity, conserve resources,
-
or even to do something as simple
as washing their mugs at work
-
so that the sink isn't
always full of dirty dishes?
-
(Laughter)
-
(Applause)
-
When I first started
working on this problem,
-
I collaborated with a power company
-
to recruit customers for a program
that prevents blackouts
-
by reducing energy demand during peaks.
-
The program is based
on a tried-and-true technology.
-
It's one the Obama
Administration even called
-
"the cornerstone to modernizing
America's electrical grid."
-
But, like so many
great technological solutions,
-
it has a key weakness:
-
people.
-
People need to sign up.
-
To try to get people to sign up,
the power company sent them a nice letter,
-
told them about
all the program's benefits,
-
and it asked them to call
into a hotline if they were interested.
-
Those letters went out,
-
but the phones, they were silent.
-
So when we got involved,
we suggested one small change.
-
Instead of that hotline,
-
we suggested that they use sign-up sheets
that they'd post near the mailboxes
-
in people's buildings.
-
This tripled participation.
-
Why?
-
Well, we all know people care deeply
about what others think of them,
-
that we try to be seen
as generous and kind
-
and we try to avoid
being seen as selfish or a mooch.
-
Whether we are aware of it or not,
this is a big part of why people do good,
-
and so small changes that give people
more credit for doing good,
-
those changes can make
a really big difference.
-
Small changes like
switching from a hotline,
-
where nobody will ever find out
about your good deed,
-
to a sign-up sheet
-
where anyone who walks by
can see your name.
-
In our collaborations with governments,
nonprofits, companies,
-
when we're trying to get people
to do more good,
-
we harness the power of reputations
-
and we have a simple checklist for this,
-
and in fact, you already know
the first item on that checklist.
-
It's to increase observability,
-
to make sure people find out
about good deeds.
-
Now, wait a minute, I know
some of you are probably thinking,
-
there's no way people here thought,
-
"Oh, well, now that
I'm getting credit for my good deed,
-
now it's totally worth it."
-
And you're right.
-
Usually, people don't.
-
Rather, when they're making
decisions in private,
-
they worry about their own problems,
-
about what to put on the table for dinner,
or how to pay their bills on time.
-
But, when we make
their decision more observable,
-
they start to attend more
to the opportunity to do good.
-
In other words, what's
so powerful about our approach
-
is that it could turn on
people's existing desire to do good,
-
in this case, to help
to prevent a blackout.
-
Back to observability.
-
I want to give you another example.
-
This one is from a collaboration
-
with a nonprofit that gets out the vote,
-
and it does this by sending hundreds
of thousands of letters every election
-
in order to remind people and try
to motivate them to go to the polls.
-
We suggested adding
the following sentence:
-
"Someone may call you to find out
about your experience at the polls."
-
This sentence makes it feel
more observable when you go to the polls,
-
and it increased the effect
of the letter by 50 percent.
-
Making the letter more effective reduced
the cost of getting an additional vote
-
from 70 dollars down to about 40 dollars.
-
Observability has been used to do things
-
like get people
to donate blood more frequently
-
by listing the names of donors
on local newsletters,
-
or to pay their taxes on time
-
by listing the names of delinquents
on a public website.
-
(Laughter)
-
What about this example?
-
Toyota got hundreds of thousands of people
to buy a more fuel-efficient car
-
by making the Prius so unique ...
-
(Laughter)
-
that their good deed
was observable from a mile away.
-
(Laughter)
-
Alright, so observability is great,
-
but we all know, we've all seen
-
people walk by an opportunity to do good.
-
They'll see somebody
asking for money on the sidewalk
-
and they'll pull out their phones
and look really busy,
-
or they'll go to the museum and they'll
waltz right on by the donation box.
-
Imagine it's the holiday season
-
and you're going to the supermarket,
and there's the Salvation Army volunteer,
-
and he's ringing his bell.
-
A few years ago, researchers in San Diego
-
teamed up with a local chapter
from the Salvation Army
-
to try to find ways to increase donations.
-
What they found was kind of funny.
-
When the volunteer
stood in front of just one door,
-
people would avoid giving
by going out the other door.
-
Why?
-
Well, because they can always claim,
"Oh, I didn't see the volunteer,"
-
or, "I wanted to get
something from over there,"
-
or, "That's where my car is."
-
In other words, there's lots of excuses.
-
And that brings us
to the second item on our checklist:
-
to eliminate excuses.
-
In the case of the Salvation Army,
-
eliminating excuses just means
standing in front of both doors,
-
and sure enough, when they did this,
-
donations rose.
-
But that's when things got kind of funny,
-
even funnier.
-
The researchers
were out in the parking lot,
-
and they were counting people
as they came in and out of the store,
-
and they noticed that when the volunteers
stood in front of both doors,
-
people stopped coming
out of the store at all.
-
(Laughter)
-
Obviously, they were surprised by this,
so they decided to look into it further,
-
and that's when they found that there
was actually a third, smaller utility door
-
usually used to take out the recycling --
-
(Laughter)
-
and now people were going out that door
in order to avoid the volunteers.
-
(Laughter)
-
This teaches us
an important lesson though.
-
When we're trying to eliminate excuses,
we need to be very thorough,
-
because people are
really creative in making them.
-
(Laughter)
-
Alright, I want to switch this setting
-
where excuses can have
deadly consequences.
-
What if I told you that the world's
deadliest infectious disease has a cure,
-
in fact, that it's had one for 70 years,
-
a good one, one that works
almost every time?
-
It's incredible, but it's true.
-
The disease is tuberculosis.
-
It infects some 10 million people a year,
-
and it kills almost two million of them.
-
Like the blackout prevention program,
we've got the solution.
-
The problem is people.
-
People need to take their medication
-
so that they're cured,
-
and so that they don't
get other people sick.
-
For a few years now,
we've been collaborating
-
with a mobile health startup
called Keheala
-
to support TB patients
as they undergo treatment.
-
Now, you have to understand,
TB treatment, it's really tough.
-
We're talking about taking
a really strong antibiotic
-
every single day for six months or more.
-
That antibiotic is so strong
that it will make you feel sick.
-
It will make you feel nauseous and dizzy.
-
It will make your pee turn funny colors.
-
It's also a problem because
you have to go back to the clinic
-
about every week
in order to get more pills,
-
and in sub-Saharan Africa
or other places where TB is common,
-
now you're talking
about going someplace pretty far,
-
taking tough and slow public transport,
-
maybe the clinic is inefficient.
-
So now you're talking about taking
a half day off of work every week
-
from a job you desperately
can't afford to lose.
-
It's even worse when you consider the fact
that there's a terrible stigma
-
and you desperately don't want people
to find that you have the disease.
-
Some of the toughest stories we hear
are actually from women
-
who, in these places where
domestic violence can be kind of common,
-
they tell us that they have to
hide it from their husbands
-
that they're coming to the clinic.
-
So it's no surprise
that people don't complete treatment.
-
Can our approach really help them?
-
Can we really get them to stick it out?
-
Yeah.
-
Every day, we text patients
to remind them to take their medication,
-
but if we stopped there,
-
there'd be lots of excuses.
-
"Well, I didn't see the text."
-
Or, "You know, I saw the text,
but then I totally forgot,
-
put the phone down
and I just forgot about it."
-
Or, "I lent the phone out to my mom."
-
We have to eliminate these excuses
-
and we do that by asking patients
-
to log in and verify
that they've taken their medication.
-
If they don't log in, we text them again.
-
If they don't log in,
we text them yet again.
-
If, after three times,
they still haven't verified,
-
we notify a team of supporters
-
and that team will call and text them
-
to try to get them back on the wagon.
-
No excuses.
-
Our approach, which, admittedly,
uses all sorts of behavioral techniques,
-
including, as you've
probably noticed, observability,
-
it was very effective.
-
Patients without access to our platform
-
were three times more likely
not to complete treatment.
-
Alright,
-
you've increased observability,
-
you've eliminated excuses,
-
but there's still a third thing
you need to be aware of.
-
If you've been to Washington, DC
or Japan or London,
-
you know that metro riders there
-
will be very careful to stand
on the right-hand side of the escalator
-
so that people can go by on the left.
-
But unfortunately,
not everywhere is that the norm
-
and there's plenty of places
where you can just stand on both sides
-
and block the escalator.
-
Obviously, it's better for others
-
when we stand on the right
and let them go by,
-
but we're only expected
to do that some places.
-
This is a general phenomenon.
-
Sometimes we're expected to do good
-
and sometimes not,
-
and it means that people
are really sensitive to cues
-
that they're expected to do good
in a particular situation,
-
which brings us to the third
and final item on our checklist:
-
to communicate expectations,
-
to tell people,
-
"Do the good deed right now."
-
Here's a simple way
to communicate expectations;
-
simply tell them, "Hey, everybody else
is doing the good deed."
-
The company Opower
sends people in their electricity bill
-
a small insert that compares
their energy consumption
-
with that of people
with similarly sized homes.
-
And when people find out that their
neighbors are using less electricity,
-
they start to consume less.
-
That same approach, it's been used
to get people to vote or give to charity
-
or even reuse their towels in hotels.
-
What about this one?
-
Here's another way
to communicate expectations;
-
simply do it by saying, "Do the good deed"
just at the right time.
-
What about this one?
-
This ticker reframes
-
the kind of mundane task
of turning off the lights
-
and turns it instead
into an environmental contribution.
-
The bottom line is,
lots of different way to do this,
-
lots of ways to communicate expectations.
-
Just don't forget to do it.
-
And that's it.
-
That's our checklist.
-
Many of you are working on problems
with important social consequences
-
and sometimes you might need
to motivate people to do more good.
-
The tools you learned today
can help you with this
-
and these tools, they don't require
that you raise additional funds
-
or that you develop
any more fancy technologies.
-
They just require harnessing reputations
-
by increasing observability,
eliminating excuses
-
and communicating expectations.
-
Thank you.
