If a single word could capture the feel of the winter holidays, it might be glow.

The word itself sounds snug and warm. It suggests candlelight,
roaring fireplaces, and lights twinkling through boughs and brightening
the darkest days of the year. It conjures the feeling that
accompanies gift-giving, too. Giving gifts
reliably creates such a cozy,
pleasurable feeling that economists dub it the “warm glow” of
generosity.
But much like the creeping shadows cast by even the cheeriest fire,
the warm glow has a dark side. Economist James Andreoni, who coined the
term, claimed that the glow of giving makes acts of generosity
ultimately selfish: If giving feels good, how generous can it really be?
Maybe gifts are just another way of using other people to make
ourselves feel good.
There is no denying the rush of positive feeling that accompanies the act of giving. When researchers
give participants a little money, those who are randomly selected to
spend it on someone else report feeling happier than those instructed to
spend it on themselves. Even one- and two-year-old toddlers feel happier
after giving cookies to a puppet than after receiving treats
themselves. And if you take away the warm glow by compensating people
for a gift—which turns giving into a transaction—generosity declines.
Neuroscience research
has linked the warm glow of giving to activity in a region of the brain
called the nucleus accumbens, where the neurotransmitter dopamine is
released, resulting in feelings of heightened well-being—and the desire
to repeat whatever caused it. This makes dopamine a key player in
addictions—cocaine, for example, also causes dopamine to spike. It would
be an overstatement to equate gift-giving with an addiction, but the warm glow of giving does tend to make people want to give more, leading to ascending spirals of generosity and reward.
This positive feedback loop can drive generosity to awe-inspiring
heights. The unforeseen rush of emotions that Bill Gates experienced
during a trip to Africa in the 1990s to give children computers
ultimately led him to create the mighty Gates Foundation. And a
businessman named Rob Mather was so moved by the experience of raising
money to help one injured child that he went on to found the Against
Malaria Foundation, which has raised over $140 million and is described
as the world’s most effective charity.
In our work,
we have interviewed dozens of some of the most extraordinary altruists
in the world—people who have given one of their own kidneys to a
stranger—and nearly all started out as blood donors and volunteers. To a
person, they say that their donation brought them immense pleasure and
that they would do it again if they could. As one altruist told us,
"There’s a euphoria that accompanies the act of living donation which is
difficult to explain without sounding a little crazy."
From a utilitarian perspective, it’s not crazy at all. It’s
undeniably a good thing that giving feels good, as it motivates us to
keep giving. But perhaps it really does make giving selfish. Andreoni
and others argue that the emotional rewards of giving rob the act of
real virtue. Maybe those who give the most are actually the most selfish people just angling for a dopamine rush.
Or maybe not.
A recent review
found that narcissists—who are genuinely selfish—are less generous than
other people, and that when they do give gifts it’s only to impress or
influence people, not because they genuinely care about them. This makes
sense. If giving were just about feeling good, a truly selfish
person would choose an easier and less costly way to get the same
result—dopamine is also released by eating chocolate and having sex, after all.
Another possibility is that taking pleasure in helping others is what it means
to be generous. Think of it this way: Would you consider someone who
gives gifts begrudgingly to be more selfless than someone who takes joy
in it? Of course not. As Buddhist monk and neuroscientist Matthieu Ricard argues, “The fact that we feel satisfaction upon completing an altruistic action presupposes that we are naturally inclined to favor the other’s happiness. If we were completely indifferent to others’ fates, why would we feel pleasure in taking care of them?”
Research in my laboratory
has identified some of the brain processes that naturally presuppose us
to take pleasure in helping. For example, in altruists who give kidneys
to strangers, parts of the brain that support parental nurturing, like
the amygdala and periaqueductal gray, are unusually large, densely
interconnected, and responsive to others’ needs. Animal studies
find that the release of the nurturing hormone oxytocin
in these brain regions when caring for others is responsible for
subsequent dopamine surges. This suggests that it is our fundamentally
caring nature that moves us to help others, and that feeling good may be
merely a lucky and foreseeable outcome of giving, rather than its
purpose—a critical distinction.
In other words: Feel free to bask in the warm glow of gift giving
this holiday. That feeling you are enjoying is a hallmark of generosity,
not its absence.
