Although gratitude is important to the good life, little is known about factors that enhance gratitude. Some have
suggested that traumatic events such as near-death experiences and life-threatening illnesses might enhance
gratitude. If reflecting on death causes one to appreciate life as a limited resource, this might enhance gratitude.
This study investigated this theory. Participants were randomly assigned to a death reflection condition,
a traditional mortality salience condition, or to a control condition. Participants in the death reflection and the
mortality salience conditions showed enhanced gratitude compared to individuals in the control condition,
supporting the theory that becoming aware of one’s mortal limitations enhances gratitude for the life that what
one has.

Introduction
The truth is that all genuine appreciation rests on a
certain mystery of humility and almost darkness. The
man who said, ‘Blessed is he that expecteth nothing,
for he shall not be disappointed’, put the eulogy quite
inadequately and even falsely. The truth is, ‘Blessed is
he that expecteth nothing, for he shall be gloriously
surprised’. The man who expects nothing sees redder
roses than common men can see, and greener grass,
and a more startling sun. Blessed is he that expecteth
nothing, for he shall posses the cities and the moun-
tains; blessed is the meek, for he shall inherit the earth.
Until we realize that things might not be, we cannot
realize that things are. Until we see that darkness we
cannot admire the light as a single and created thing.
As soon as we have seen that darkness, all light is
lightening, sudden, blinding, and divine. ...It is one of
the million wild jests of truth that we know nothing
until we know nothing.
–Chesterton (1905/1986a, p. 69, italics added).
How do grateful people become grateful? How
does gratitude develop in a person? In the epigraph,
Chesterton suggests that when one recognizes ‘that
things might not be’ she develops a deep appreciation
for these things. Thus, one important component of
the grateful person may be that they understand that
the benefits they enjoy now ‘might not be’. Perhaps
when individuals become aware that life is a benefit
that is not a given, they then gain an appreciation and
gratitude for the life that they have. By reflecting on
one’s own mortality, this could enhance one’s aware-
ness that their life ‘might not be’, and hence might
become more grateful for the life they have. Do people
become more grateful when they are reflecting on their
own death? The purpose of this study was to investi-
gate this question.
Research has converged to support the conclusion
that gratitude is an important component of the good
life. Trait gratitude measures are strongly correlated
with various measures of subjective well-being (e.g.,
McCullough, Emmons, & Tsang, 2002; Watkins,
Woodward, Stone, & Kolts, 2003b; Wood, Joseph, &
Maltby, 2008), longitudinal studies have found that
gratitude predicts increased well-being over time, and
gratitude is one of the strongest predictors of happiness
amongst the strengths identified by the Values In
Action project (Park, Peterson, & Seligman, 2004;
Peterson & Seligman, 2004). Furthermore, experimen-
tal studies have provided promising evidence that
gratitude exercises may actually enhance immediate
mood state (Watkins et al., 2003b), and long-term
subjective well-being (Emmons & McCullough, 2003;
Froh, Sefick, & Emmons, 2008; Lyubomirsky,
Sheldon, & Schkade, 2005; Seligman, Steen, Park, &
Peterson, 2005, for a review, see Watkins, Van Gelder,
& Frias, 2009). Thus, not only is there a strong
tendency for grateful individuals to be happy, but now
there also appears to be some evidence that gratitude
causes enhanced subjective well-being.

While there appear to be a number of benefits to
gratitude, to date there is little evidence that speaks to
the question of how gratitude develops in a person.
What makes a grateful person grateful? Although this
would appear to be an important question, few
studies have set out to investigate this issue. Several
possible gratitude development mechanisms seem
plausible. First, a secure attachment base may be
critical for the development of gratitude (Lystad,
Watkins, & Sizemore, 2005). In a related vein, it
would seem to follow that early emotional training
would be important to the development of gratitude.
Children exposed to caregivers who model and
reinforce grateful responding would seem to be at
an advantage in the development of gratitude.
Likewise, parents who teach their children to appre-
ciate simple pleasures rather than seeking spectacular
pleasures should be more likely to enhance gratitude
in their children. Indeed, the appreciation of simple
pleasures does appear to be an important factor of
trait gratitude (Watkins et al., 2003b). Furthermore,
in an experimental design, we found that the appre-
ciation of natural beauty (a simple pleasure) enhances
state gratitude (Watkins, Gibler, Mathews, & Kolts,
2005). Spiritual development may also be important
to the development of trait gratitude. Some evidence
exists in support of this notion in that actively
religious/spiritual individuals are more likely to be
grateful (Emmons & Kneezel, 2005; McCullough
et al., 2002; Watkins et al., 2003b). More generally,
the development of prosocial traits such as trust and
agreeableness, should provide an important founda-
tion for building the trait of gratitude.
While all of these putative avenues to gratitude
deserve empirical attention, we chose to focus on
another potential route: exposure to difficult circum-
stances. In particular, we focused on how life-
threatening circumstances might enhance gratitude.
Because of the emotional law of habituation (Frijda,
1988, 2007), we tend to become accustomed to bene-
ficial situations that are relatively unchanging.
Certainly, life itself is one of those benefits that we
enjoy constantly (at least while we are alive), and thus
we often fail to notice the basic advantages of life and
may even take this benefit for granted. When one is
confronted, however, with a situation where their life is
in jeopardy, appreciation for this benefit may result
because they have become more aware of what ‘might
not be’ – which in this case is life itself. Here, we follow
the approach of Janoff-Bulman and Berger (2000),
who argued that appreciation is simply the cognitive
process of appraising something with increased value.
Just as real estate may ‘appreciate’ in monetary value,
so one’s appreciation for life may increase when
confronted with their death.
Several studies have found that people who have
been confronted with life-threatening diseases report
that their appreciation for life itself has increased (e.g.,
Taylor, 1983), and others have noted that very grateful
people have often gone through very difficult – if not
life threatening – circumstances (e.g., Emmons, 2007).
These studies rely on retrospective anecdotal reports,
and thus experimental designs are needed to test these
ideas more carefully. Furthermore, in the appreciation
scale developed by Adler and Fagley (2005), one of
their items (‘thinking about dying reminds me to live
each day to its fullest’, p. 94) clearly suggests that this
may be an important element of appreciation and
gratitude. Indeed, we have argued that trait gratitude is
characterized by the attitude that all of life is a gift
(Watkins et al., 2003b). Perhaps when an individual
endures a life-threatening experience, this decreases
the tendency to take life for granted and thus
increases one’s awareness that life itself is a gift to be
thankful for. In this study, we sought to test this
theory by enhancing awareness of one’s own death
in the lab.
Two methods have emerged for increasing
participants’ awareness of their mortality in research
settings: mortality salience and death reflection. In
mortality salience manipulations, some subjects are
exposed to some aspect of death, and simply writing
about one’s own death seems to be the most commonly
used method (Rosenblatt, Greenberg, Solomon,
Pyszczynski, & Lyon, 1989). Mortality salience induc-
tions have been shown to produce a number of
unsavory results: increased greed, racism, and ethno-
centrism (Koole, Greenberg, and Pyszczynski, 2006).
Terror management theory (TMT; Greenberg,
Solomon, & Pyszczynski, 1997) has provided a com-
pelling account of these rather diverse effects. TMT
argues that when one is indirectly confronted with their
own mortality, the individual engages in defenses to
enhance their personal value and so to enhance their
‘symbolic mortality’. Mortality salience effects, how-
ever, seem to be in direct contrast to research on post-
traumatic growth (where often the individual has been
confronted with their own mortality, Calhoun &
Tedeschi, 2001) and to our proposal that becoming
more aware of one’s own mortality should enhance
gratitude. Recently, however, another mortality sal-
ience manipulation has appeared in the literature called
‘death reflection’ (Cozzolino, 2006; Cozzolino, Staples,
Meyers, & Samboceti, 2004). In this induction, partic-
ipants are asked to imagine their own death in a very
specific and vivid manner (dying in a house fire). This
manipulation was designed to emulate the core features
of near-death experiences (Ring & Valarino, 1998). In
contrast to conventional mortality salience manipula-
tions, death reflection appears to produce salubrious
results, such as increased intrinsic behavior and less
greed (Cozzolino, 2006; Cozzolino et al., 2004).
Why the contrasting effects? Working off of
several other analyses of this apparent paradox

(Cozzolino, 2006; Pyszczynski, Greenberg, Solomon,
& Maxfield, 2006), we propose that in conventional
mortality salience manipulations people confront their
own mortality in such a way as to allow individuals
to use their typical defenses against the full realization
of their mortality. Thus, writing about one’s own
death may permit individuals to look at their
mortality in a more abstract, philosophical, and
detached manner, which permits them to maintain
their own symbolic immortality with cognitive pro-
cesses that tend to operate more toward the back-
ground of awareness. In the death reflection
induction, however, individuals must confront their
own mortality in a specific and vivid manner, and this
pushes them to consider their own mortality more
directly in a more personal and experiential manner.
Hence, the death reflection manipulation encourages
an individual to face their own mortality head on,
and people cannot easily use their typical defenses to
deny their own inevitable death. When individuals are
forced to look at their death in a way that feels more
real to them, they must fully confront their mortality
and go beyond the typical symbolic immortality
defenses to what might be more positive ways of
dealing with their mortality. Thus, we submit that
individuals who confront their mortality via death
reflection will be more likely to show enhanced
gratitude than those who engage in the typical
mortality salience induction.
In this study, participants were randomly assigned
to one of the three conditions: a control condition, the
traditional mortality salience condition, or the death
reflection manipulation. We measured emotional state
(including gratitude), both before and after our
manipulation, and then participants completed a
number of questionnaires designed to evaluate
individual differences that might moderate the
treatment effects. We predicted that death reflection
would show enhanced gratitude compared to the
control condition.
Method
Design and overview
We used a 2 (time: before and after treatment) 3
(mortality salience condition: control, typical mortality
salience and death reflection) mixed factorial design
with state gratitude and gratitude for life as the
dependent variables. Time was a repeated measure
and mortality salience was the between subjects vari-
able in this design.
Participants
Participants were 116 (75% female and 25% male)
undergraduates at Eastern Washington University.
Eighty-four percent of participants were between the
age of 18 and 25, 14% between 26 and 40, and 2%
were 40 or older. Seventy-five participants were
Caucasian and 40 were ethnic minorities (13
Hispanic, 8 African American, 4 Asians, 2 Pacific
Islander, 1 Native American, 1 Middle Eastern, 8
Biracial, 2 Multiracial, and 1 was of other ethnic
background). Twenty-eight percent were freshman,
16% were sophomores, 28% were juniors, and 28%
were seniors. Ninety-one percent were single, 3% were
married, 3% were divorced, and 2% were remarried.
Sixty-one identified themselves as Christian, 18
Catholic, 10 Agnostic, 8 Atheist, 2 Protestant, 2
Muslim, 1 Buddhist, 1 Catholic–Protestant, 1 as
Catholic-Christian, 1 Protestant-Christian, and 11
identified themselves as other religious preference.
They received a course credit for their participation.
Three participants had incomplete data or failed to
follow the directions and thus were excluded. Thus, the
final participant pool was 113 students.
Materials
Assessment of emotional state both before and after
treatment was accomplished with the Positive and
Negative Affectivity Scales (PANAS). The PANAS is
one of the most well-developed measures of positive
and negative affectivity (Watson, Clark, & Tellegen,
1988). This measure is based on the theory that positive
and negative emotional states are not simply bipolar
opposites, but are largely orthogonal axes in affective
space. Before the manipulation, we administered the
PANAS-X (Watson & Clark, 1994), and after
the manipulation we administered the short version
of the PANAS. The PANAS-X was administered with
the instructions ‘Indicate to what extent you have felt
this way during the past few weeks’. This is the
extended version of the PANAS and includes 60 items
that tap positive and negative affect as well as
additional emotional subscales. The instructions for
the short PANAS were for immediate emotional state
(‘Indicate to what extent you feel that way right now,
that is, at the present moment’). Psychometrics for the
PANAS were good (coefficient alpha pre-test:
PA ¼ 0.85, NA ¼ 0.85; Cronbach’s alpha post-test:
PA ¼ 0.90, NA ¼ 0.89).
Assessment of grateful state
We administered the PANAS with three additional
adjectives of grateful, thankful, and appreciative.
These adjectives have been shown to provide a reliable
indicator of grateful emotion (McCullough et al., 2002)
and were included with both administrations of
the PANAS (Cronbach’s alpha pre-test ¼ 0.90,
post-test ¼ 0.94).

Gratitude for life scale
We initially created four questions that we felt tapped
the core of gratitude. Participants were instructed to
provide an honest answer and indicate their response
on a bipolar 4-point Likert type scale ( 4 ¼ extremely
ungrateful for my life, 4 ¼ extremely grateful for my
life). Gratitude for life was assessed by examining
responses to the following four questions: (1) How
grateful are you for your life?, (2) How thankful are
you for being alive?, (3) Right now, how much do you
feel that your life is a gift?, and (4) How appreciative
do you feel for your life right now? Internal consistency
of this measure was good (Cronbach’s alpha ¼ 0.87).
Moderator variables
At the end of the study, participants took several
questionnaires that tapped potential moderator vari-
ables such as intrinsic/extrinsic religiosity, nearness to
God, trait gratitude, trait indebtedness, and subjective
well-being. Because none of the moderator analyses
reached significance, we will not comment on these
measures further.
Experimental conditions
Death reflection scenario
We used the mortality salience manipulation reflected
in the creation of a scenario, called death reflection by
Cozzolino et al. (2004). This scenario was developed to
encompass the three core elements of the near-death
experience as outlined by Ring and Valarino (1998).
In the death scenario, participants imagined waking up
in the middle of the night in a friend’s apartment on
the ‘20th floor of an old, downtown building’ to the
‘sounds of screams and the choking smell of smoke’.
The scenario details the participant’s futile attempts to
escape from the room and burning building before
finally giving in to the fire and eventually death.
Cozzolino et al. (2004) created four questions that were
generated to activate some of the common elements
found in near-death experiences. The questions
included: (1) Please describe in detail the thoughts
and emotions you felt while imagining the scenario,
(2) If you did experience this event, how do you think
you would handle the final moments? (3) Again
imagining it did happen to you, describe the life you
led up to that point, and (4) How do you feel your
family would react if it did happen to you?
Mortality salience condition
Previous method of inducing mortality salience as
developed by Rosenblatt et al. (1989) was used in this
study asking, ‘In as many words and in as much detail
as possible, please describe the thoughts, feelings, and
emotions you experience when thinking about your
own death’.
Control condition
Participants read a similar scenario to the death
reflection manipulation in that they imagined waking
up to ‘begin another typical day’ (Cozzolino et al.,
2004). In this scenario, participants imagined spending
the day following a laid back routine and taking care
of mundane tasks (i.e., making breakfast, doing
laundry, cleaning) before ending the day. After reading
the ‘no death’ control condition, participants answered
the following questions: (1) Please describe in detail the
thoughts and emotions you felt while imagining the
scenario (2) Have you ever experienced an event like
the one described in the scenario? (3) Imagining an
event like the one described did happen to you,
describe the life you led up to that point, and
(4) Again imagining this event did happen to you,
describe the thoughts and emotions of how your family
members would react. These questions were designed
to mirror the death reflection questions, providing
control participants an opportunity to reflect on their
life and to take the perspective of others.
Procedure
Female experimenters tested all participants individu-
ally. Participants read and signed a consent form
agreeing to participate in the study and then responded
to a demographic sheet that included questions
regarding gender, age range, class standing, marital
status, ethnicity, and religious orientation. These were
completed anonymously prior to administration of the
study packet. Participants were randomly assigned to
one of three conditions. In the death reflection
condition, participants were asked to read and vividly
imagine themselves experiencing the events described
in a scenario and then to answer open-ended questions
as if the events actually occurred. After reading the
death scenario, participants answered four open-ended
questions. In the mortality salience condition, partic-
ipants were asked ‘In as many words and in as much
detail as possible, please describe the thoughts,
feelings, and emotions you experience when thinking
about your own death’ (e.g., Goldenberg, McCoy,
Pyszczynski, Greenberg, & Solomon, 2000). In the
control condition, participants read a similar scenario
to the death reflection manipulation in that they
imagined waking up to ‘begin another typical day’.
In all conditions, after reading the scenario, partici-
pants were given 3 minutes to complete the respective
questions. After the completion of the final question,
participants were then told they could complete the rest
of the study at their own pace. Following the manip-
ulation, participants completed the Gratitude for Life

Scale indicating on a bipolar 4-point Likert type scale
(4 to 4) indicating how grateful they felt for their life.
Participants then completed the short PANAS
(Watson et al., 1988) which included a state gratitude
measure, followed by administration of the potential
moderator variables. Finally, participants were
debriefed and awarded their compensation.
Results
Primary analysis
Our principal analysis involved our two dependent
variables: gratitude for life and grateful state. For our
grateful state variable, we conducted a univariate
GLM ANCOVA where pre-test state gratitude was
the covariate and post-test state gratitude was the
dependent variable. Results showed that the effect of
condition was significant as expected, F(2, 109) ¼ 5.92,
p ¼ 0.004,
2
p ¼ 0.10. The pattern of means followed
our predictions: the death reflection induction showed
the greatest increase in state gratitude, followed by the
traditional mortality salience treatment and the con-
trols. Figure 1 demonstrates this effect. LSD pairwise
comparisons of post-test estimated marginal gratitude
means showed that gratitude was significantly greater
in the death reflection condition compared with the
controls (p ¼ 0.001, d ¼ 0.80), and state gratitude in the
mortality salience condition was significantly different
from the controls (p ¼ 0.03, d ¼ 0.49), but not the death
reflection condition (p ¼ 0.20, d ¼ 0.30). Means for
state gratitude by condition are listed in Table 1. For
the gratitude for life dependent variable, we conducted
a univariate ANCOVA with pre-gratitude state as a
covariate. The effect of condition was marginal,
F(2, 109) ¼ 2.89, p ¼ 0.06,
2
p ¼ 0.050. The pattern of
means was as expected.

In order to more carefully investigate the changes
in gratitude within each experimental condition, we
conducted paired t-tests comparing pre- and post-
gratitude. As expected, in the death reflection condi-
tion, a significant increase in gratitude was found,
t(35) ¼2.30, p ¼ 0.028. No significant change was
observed in the mortality salience condition,
t(39) ¼0.98, p ¼ 0.332, and in the control condition
there was a non-significant trend for decreased
gratitude, t(37) ¼ 1.74, p ¼ 0.90.
Impact of treatment on positive affect
In order to evaluate whether this effect was unique to
gratitude or was more generally applicable to positive
affect, we conducted a secondary analysis with positive
affect as the dependent variable. Following our previ-
ous analyses, we conducted an ANCOVA with pre-test
positive affect as the covariate. The effect of condition
was not significant, F(2, 109) ¼ 1.20, p ¼ 0.30,
2
p ¼ 0.02. Furthermore, as with gratitude, we con-
ducted paired t-tests by experimental condition to
more closely evaluate changes in positive affect as a
result of the experimental manipulation. In the death
reflection condition, positive affect decreased but this
change did not reach significance, t(35) ¼ 0.88,
p ¼ 0.35. Similarly, in the mortality salience condition,
positive affect showed a non-significant decline,
t(39) ¼ 0.73, p ¼ 0.470. In the control condition, pos-
itive affect decreased significantly, t(37) ¼ 2.56,
p ¼ 0.015. In order to more rigorously test whether
the impact of our experimental condition was unique
to gratitude, we conducted a factorial condition time
(pre- and post-test) ANCOVA for gratitude using both
pre- and post-test positive affect as covariates. After
controlling for positive affect, the predicted condi-
tion time interaction was still significant,
F(2, 108) ¼ 4.67, p ¼ 0.011,
2
p ¼ 0.080, replicating the
finding for gratitude as described earlier. Thus, the
impact of death reflection on gratitude appears to be
unique. Means and standard errors of positive affect
can be found in Table 2.

Discussion
In this study, we found that death reflection – focusing
in a specific and vivid way on one’s death – signifi-
cantly enhanced state gratitude compared to subjects
that did not think about their own mortality.
Supporting anecdotal reports from those who have
experienced near-death or life-threatening diseases,
confronting one’s mortality in this experiential
manner tends to enhance feelings of gratitude. Our
experimental findings also provide a theoretical mech-
anism for some of the apparent benefits that arise from
trauma reported in the post-traumatic growth litera-
ture (Park & Helgeson, 2006). This adds to a growing
literature showing that not all mortality salience
inductions result in undesirable consequences; death
reflection has now been shown to increase intrinsic
motivation, decrease greed (Cozzolino, 2006;
Cozzolino et al., 2004), and increase gratitude.
Although death reflection did not show a signifi-
cantly greater increase in gratitude compared to the
traditional mortality salience induction – though when
compared to controls the effect size for death reflection
was large while the effect size for mortality salience was
medium – the pattern of means did follow our
predictions showing that death reflection was more
effective in enhancing gratitude. Death reflection
resulted in a significant increase in gratitude, while
the mortality salience condition showed no significant
change. Why did the death reflection induction show a
greater increase in gratitude than the traditional
mortality salience induction? Following Cozzolino
(2006) and Pyszczynski et al. (2006), we believe that
writing about one’s own death may permit subjects to
analyze their mortality at a more abstract level,
allowing them to maintain their denial of their
inevitable demise. Death reflection, however, pushes
individuals past these defenses to confronting their
mortality in a personal and experiential manner. When
one is fully confronted with the reality that life ‘might
not be’, life itself is seen as a limited resource that one
is not entitled to, and thus appreciation for life
increases. However, because these two conditions
were not significantly different in this study, future
research may want to develop more definitive mortality
salience inductions that clearly distinguish between
these mechanisms as we have described them.
We found that reflecting on one’s own death
enhances gratitude, but might reflecting on other
potential losses also increase gratitude? It might be
that death reflection is not unique in this regard;
focusing on the potential loss of anything might
enhance one’s awareness that this thing ‘might not
be’, and thus enhance one’s appreciation for that which
they formerly took for granted. Indeed, there is some
evidence for this. In a recent series of studies (Koo,
Algoe, Wilson, & Gilbert, 2008), thinking about the
potential absence of a positive event from one’s past
increased gratitude compared to comparison condi-
tions, and thinking about the absence of a romantic
partner increased one’s appreciation for their partner.
Thus, being confronted with the possibility that any
benefit ‘might not be’ – including the benefit of life
itself – might increase one’s gratitude and appreciation
for those benefits.
One rather peculiar finding deserves comment. We
found that controls actually decreased in positive affect
from pre- to post-test. Although this might be because
controls did not particularly enjoy being in this study,
we think it is more likely because intensity of emotion
declined more generally. Reporting how one had felt
‘in the past 2 weeks’ (as our participants did at pre-test)
is probably an exaggerated estimate of their actual
emotional experience, and is probably somewhat
enhanced relative to our participant’s current emo-
tional state. This represents one limitation of the study,
as some would argue that it would be better to measure
incoming emotional differences with participant’s
report of how they are feeling right now. We chose
to control for pre-test individual differences in emo-
tional state with ‘the past 2 weeks’ instruction because
we felt that changing the format would reduce demand
characteristics and testing effects. Whatever the case, it
is likely that our participants’ report of their emotional
state for the past 2 weeks was highly related to their
current emotional state, and hence this served as a
good covariate. Thus, the decline of positive affect of
those in the control condition likely reflects a general
decrease in report of emotional intensity. Given that
background, it is even more interesting that partici-
pants in the death reflection condition actually showed
a significant increase in gratitude.
Our findings encourage us to speculate on several
practical implications. First, death reflection may be a
good exercise for enhancing state gratitude. Although
experimental studies have shown that enhancing
gratitude results in increased subjective well-being
(e.g., Emmons & McCullough, 2003; for a review, see
Watkins et al., 2009), more research needs to investi-
gate exercises that might enhance gratitude. Death
reflection appears to be one way that individuals can

enhance their appreciation and gratitude for life.
In this study, our participants were engaged in a
relatively short death reflection induction. What might
be the long-term impact of engaging regularly in a
similar exercise? It seems likely that our participants’
confrontation with their own death was soon
forgotten. But could people develop a more chronic
appreciation of their own mortality if they regularly
engaged in such an exercise? When one is more
consistently aware of their own mortality, how does
this impact them? We submit that this may be an
important facet of the grateful person, but these
questions beg for more research.
In this study our participants focused on their own
death, but what might be the impact of reflecting on
the death of a loved one? For example, when one
believes that their spouse is in a life-threatening
situation, such as a dangerous airline flight, it would
seem that one’s gratitude for their spouse would
increase after the incident because they have recog-
nized that their spouse ‘might not be’ and hence their
appreciation and gratitude for their relationship is
enhanced. Future research may want to study this
possibility, and this might be an interesting
intervention for improving relationship satisfaction.
Related research that asks subjects to imagine how
their relationship might never have come to be has
shown that this enhances relationship satisfaction
(Koo et al., 2008).
We have argued that by reflecting on one’s death,
this increases gratitude by increasing appreciation for
life as a gift. Because our very existence is a constant
benefit that we adapt to easily, this is a benefit that is
easily taken for granted. Reflecting on one’s own death
might help individuals take stock of this benefit and
consequently increase their appreciation for life. One
way this may affect daily life is through increasing
appreciation for simple pleasures. As Chesterton
(1905/1986a) suggested in the epigraph, by under-
standing the darkness of non-existence, this may
increase our awareness and enjoyment of everyday
pleasures. In Chesterton’s words: ‘The man who
expects nothing sees redder roses than common men
can see, and greener grass, and a more startling sun’.
Thus, one advantage that results from death reflection
may be increased appreciation for simple pleasures.
Because research has shown that happiness is not so
much composed of spectacular pleasures, but rather
the frequency of positive emotional experiences
(Diener, Sandvik, & Pavot, 1990), appreciating
simple pleasures may be an important component of
happiness. This is because by definition these events
take place much more frequently than spectacular
pleasures such as a Caribbean cruise. Thus, a prom-
ising direction of future research would be to investi-
gate whether exercises such as death reflection enhance
one’s appreciation for simple pleasures.
One clear limitation of this study is that the age
range of our participants was relatively small. While
this is always an external validity issue in studies using
college students, this limitation is particularly worth
noting here because some mortality salience studies
have found age effects. For example, Maxfield et al.
(2007) found that while younger adults showed
increased harshness in their moral judgments after a
mortality salience induction, older adults did not.
Thus, a fruitful path for future research might be to
investigate the moderating effect of age on death
reflection and gratitude.
The reason that mortality salience seems to have
limited impact on older aged adults might be that
because of their age these individuals are chronolog-
ically closer to death and thus their mortality is already
salient to them. If so, one might predict that older
adults would show more gratitude than their younger
counterparts. Other natural events that expose indi-
viduals to their own mortality might be expected to
show enhanced gratitude. Indeed, Peterson and
Seligman (2003) found that ‘theological virtues’ such
as gratitude increased following the events of 9/11.
Similarly, we found that trait gratitude in the fall of
2001 was higher in students than in the fall quarters of
the previous 2 years (Watkins, Masingale, & Whitney,
2003a). A possible mechanism for these observed
increases in gratitude might be because the events of
9/11 made individuals more aware of their mortality,
which increased their appreciation for the benefit of life
(i.e., the perceived value of life span enhanced) and
hence increased gratitude. Of course, these ideas are
highly speculative at this point and future research in
this area could be quite informative.
A complimentary explanation for our finding
comes from the recent research of King, Hicks, and
Abdelkhalik (2009). In their first study they found that
after subtle reminders of death, their participants
increased their evaluation of life. We feel that the
authors’ interpretation of their results compliments our
findings. When through death reflection one recognizes
that ‘things might not be’ life is viewed as more scarce,
and hence appreciation (and gratitude) for life is
enhanced. Further investigations into the mechanism
of this effect should prove fruitful.
Both philosophers and psychologists have pro-
posed that humility is a prerequisite for gratitude, and
that narcissism should inhibit gratitude. Recent
research has provided some correlational support for
this idea. Trait gratitude is positively correlated with
humility (e.g., Uhder, Watkins, & Hammamoto, 2010)
and negatively associated with narcissism (after
controlling for self-esteem; McLeod, Maleki, Elster,
& Watkins, 2005). Because an accurate recognition
of one’s limitations is often cited as a core component
of humility, it would follow that the humble
person would have a keen sense of their own mortality.

As the epigraph suggests, Chesterton certainly saw
an important relationship between humility and the
recognition of the possibility of non-existence.
Thus, a chronic recognition of the limitations of life
may be an important facet of both humility and
gratitude.
Little is known about how the disposition of
gratitude develops. We have suggested that amongst
other things, experiences that lead to a clear sense of
one’s mortality may be important in the development
of gratitude. Thus, experiences such as near-death
events and life-threatening illnesses may lead to low-
ering one’s threshold for gratitude. It would be very
unlikely, however, that these events would have a
direct relationship with gratitude. Certainly, a close
brush with death might lead some to be increasingly
bitter about life rather than more grateful. Thus, it
would be interesting to investigate what kind of
psychological processes might lead some individuals
who are confronted with their own mortality to
increased gratitude, while others become less grateful.
Our experimental finding here supports the theory that
experiences where one is confronted with their own
mortality lead to enhanced trait gratitude. In this
study, however, we necessarily investigated state
gratitude, and it is somewhat of a leap to conclude
that by manipulating state gratitude with death
reflection, this might also lead to increases in trait
gratitude over time. Thus, it would be interesting to
investigate how actual events that lead individuals to
confront their own mortality might impact the devel-
opment of trait gratitude. Do near-death experiences
and surviving a life-threatening illness enhance the
development of dispositional gratitude? Although
anecdotal evidence suggests that they might, we wait
for more controlled research for the answer to this
important question.
In conclusion, this study found that when one
confronts their own death in a specific and vivid
manner, their feelings of gratitude tend to increase.
When one is pushed past their defenses of denying their
own death, people tend to recognize ‘what might not
be’ and become more grateful for the life they now
experience. Fully recognizing one’s own mortality may
be an important aspect of the humble and grateful
person. Perhaps when we recognize that death is a
reality we all must face, we may then realize along with
Chesterton (1908/1986b, p. 267) that ‘Life is not only a
pleasure but a kind of eccentric privilege’.
