THE INFLUENCE OF ENTITATIVITY ON CHARITABLE GIVING
Abstract
People often react strongly and donate generously to an individual victim. However,
emotional reactions and donations to a large number of victims are typically more muted.
Our experiments show that people donate more to large numbers of victims if these are
perceived as entitative—belonging to a single, coherent unit. For example, donations to
help a large number of animals are higher when these belong to a herd. Priming tasks that
make participants more likely to perceive victims as entitative have a similar effect. We
suggest entitativity increases the strength and coherence of victims’ defining traits. Thus,
victims with positive traits are viewed more positively when entitative, increasing
concern and donations. However, increasing the entitativity of victims that share negative
traits has the opposite effect, reducing concern and donations.
Keywords: charitable giving, entitativity, scope insensitivity

THE INFLUENCE OF ENTITATIVITY ON CHARITABLE GIVING
All for One: The Influence of Entitativity on Charitable Giving
People react strongly to images, names, and personal stories of individual victims.
In the 1980s, a photograph of an Afghan orphan girl on the cover of National Geographic
captured public imagination and became a symbol both of the Soviet-Afghan conflict and
of the refugee situation worldwide. A foundation in her honor was established, leveraging
the public interest in her story to help the hundreds of thousands of other children
victimized by the war. However, when it comes to helping large numbers of victims,
charitable reactions are typically more muted (see Slovic, 2007, for a review). People
tend to donate less to a large number of statistical victims than to a single identified
victim (Small, Loewenstein, & Slovic, 2007).
The apathy for large numbers of victims relative to the generousness to single
identified victims has been decried as virtually impossible to overcome (Slovic, 2007). It
is seen as tragic and an inefficient use of public resources, and blamed as one reason for
the weak response to several large-scale genocides throughout history (Slovic, 2007). A
prominent explanation for this phenomenon is that identifying victims with details such
as names and pictures triggers emotion and increases donations (Kogut & Ritov, 2005b;
see also Small et al., 2007). We propose another reason: Large groups lack the
psychological coherence and unity that single victims possess. Indeed, we demonstrate
that people can show strong emotional reaction and donate generously to large numbers
of victims when they form a single entity.
To motivate our hypothesis, consider two recent findings in this literature that
initially appear discrepant. Small and Loewenstein (2003) showed that the effect of
victim-identifying information on donations can extend to groups: People donated more
3

to help an identified group of victims than an unidentified group. On the other hand,
Kogut and Ritov observed no effect of victim-identification when a donation appeal
concerned multiple victims (Kogut & Ritov, 2005a; 2005b). One potentially important
feature of Small and Loewenstein’s study is that the victims in the charitable appeal
belonged to the same family. In contrast, the victims in Kogut and Ritov’s studies were
not connected in any meaningful way.
The fact that identifying information influenced donations for a family but not for
a group of unrelated victims implies that the degree to which a collection of victims
forms a meaningful entity can, as we suggested, play a role in concern and donations.
Theoretically, we draw primarily on the concept of entitativity—the extent to which a
social aggregate is perceived as a coherent unit or real entity (Campbell, 1958).
Entitativity is an important factor in explaining why people form different
impressions of groups than individuals (Hamilton & Sherman, 1996). When people form
impressions of an individual, they tend to see him or her as a psychologically coherent
unit and expect consistency of traits or behaviors. A group of individuals, on the other
hand, tends to be less entitative than a single individual (McConnell, Sherman, &
Hamilton, 1997): People expect and perceive less consistency and coherence in groups
(Hamilton & Sherman, 1996). Critically, perceived entitativity results in stronger
perceptual and emotional reactions for an individual than a group (Hamilton & Sherman,
1996).
Notably, however, some groups produce judgments similar to those produced by
individuals. Examples are intimacy groups—groups that are important to their members
and impermeable, such as families, friends, and street-gangs (Brewer, Hong, & Li, 2004;
4
THE INFLUENCE OF ENTITATIVITY ON CHARITABLE GIVING
Hamilton, Sherman, & Rodgers, 2004; Lickel et al., 2000). Emphasizing common values,
purpose, and fate can therefore increase perceived entitativity (Abelson, Dasgupta, Park,
& Banaji, 1998). Entitativity can also be increased through perceptual, Gestalt features
such as proximity, symmetry, similarity, or collective movement (Bartels & Burnett,
2010; McConnell et al., 1997; Yzerbyt, Rogier, & Fiske, 1998).
When assessing highly entitative groups, people attempt to extract their
underlying essence, just as they do for individuals (Yzerbyt, Rocher, & Schadron, 1997).
Consequently, entitative groups elicit stronger judgments than non-entitative groups, with
attributions, emotional reactions, and behavior all magnified (Abelson et al., 1998;
Brewer et al., 2004; Dasgupta, Banaji, & Abelson, 1999; Spencer-Rodgers, Hamilton, &
Sherman, 2007; Thakkar, 2006). It has also been suggested that the magnification of
responses for entitative groups can result in more extreme impressions of a group’s traits
(see Thakkar, 2006, for a discussion).
Drawing on these ideas we suggest that, for victims with positive traits, increased
entitativity should elicit greater emotional concern and higher donations. This is what we
find in our first two experiments. However, for victims with negative traits, entitativity
may decrease emotional concern and donations. We show this in our final experiment.
Though entitativity has recently emerged as a possible explanation for greater
sympathy and charitable response towards single identified victims, it has not been
systematically manipulated (Dickert, 2008; Kogut & Ritov, 2005a; 2005b; Slovic, 2007).
In particular, there have been no tests of the role of entitativity in charitable response that
hold number of victims and other factors such as identifying information constant.
5
THE INFLUENCE OF ENTITATIVITY ON CHARITABLE GIVING
Similarly, measures of perceived entitativity have provided mixed results (Dickert, 2008;
Thakkar, 2006).
In the experiments that follow, we employ a variety of settings involving human
and animal victims, vary number of victims, elicit hypothetical and real donations, and
manipulate entitativity in two ways—conceptually and perceptually. First, we contrast
donations to large numbers of victims that belong to the same intimacy group with
donations to the same number of victims not connected in any way. We also employ a
perceptual manipulation of the construct by priming Gestalt versus piecemeal processing
in a preceding task.
Study 1a: Increasing Donations through Conceptual Entitativity
In this experiment, we manipulated perceived entitativity by presenting the
victims as belonging to the same intimacy group or not. We then measured participants’
concern for the victims and their charitable donations.
Method
One hundred and twenty six students from a large Midwestern-USA university
were paid $10 each in exchange for participating in a series of unrelated studies.
Participants were presented with a hypothetical scenario in which gazelle on a preserve
were being killed by hyenas and were asked to indicate how much they would donate to
help build an $8,000 protective fence. The presentation of the number of gazelle at risk
was manipulated between participants: A single gazelle, 200 gazelle, or a herd of 200
gazelle. Note that while there are two entitative-victim conditions—the single gazelle and
the herd of 200 gazelle—we are primarily interested in the contrast between the entitative
6
THE INFLUENCE OF ENTITATIVITY ON CHARITABLE GIVING
200 and unrelated 200 gazelle. Participants indicated their donation intention on a scale
from $0 to $50 in $5 increments (a fill-in-the-blank other option was never selected).
To test whether the manipulation of entitativity changed participants’ emotional
concern for the victims, we also asked how touched, upset, morally responsible, and
sympathetic participants felt towards the gazelle on 1 (not at all) to 7 (extremely) scales
(adapted from Small et al., 2007). We combined these measures into a single measure of
concern (α = .89).
Results and Discussion
We predicted that increasing the entitativity of victims with favorable traits would
increase the emotional and charitable response to them. A pre-test examining how
beautiful, pleasant, and good participants imagined the gazelle (α > .88) confirmed that
gazelle were viewed positively, M = 1.68, SD = 1.45, t(80) = 10.46, p < .001, d = 1.16,
significantly higher than the neutral midpoint of zero on the 11-point scale. An ANOVA
revealed an effect of victim presentation on donation amount in the main study, F(2, 123)
= 3.26, p = .042, ηp2 = .05. Figure 1 shows that donations to a single gazelle were not
different from donations to 200 gazelle, F(1, 123) = 2.15, p = .146, d = .38. This result
replicates the finding of similar donations to single and multiple victims who are not
identified (Kogut & Ritov, 2005a; 2005b). However, as we predicted, donations were
higher for a herd of 200 gazelle than for 200 unrelated gazelle, F(1, 123) = 6.46, p = .012,
d = .55. Similar results were found for the medians.
The two entitative conditions (single and herd) were treated similarly in
donations, F(1, 123) = 1.16, p = .283, and concern, F(1, 123) = .90, p = .854. We
7
THE INFLUENCE OF ENTITATIVITY ON CHARITABLE GIVING
combined them and, as predicted, rating of concern fully mediated the effect of
entitativity on donations, Sobel Z = 2.18, p = .029.
The results of Study 1a show that entitativity leads to higher donations and that
this effect is mediated by participants’ concern for the victim(s). Participants donated
more to save a herd of 200 gazelle than 200 unrelated gazelle. This suggests that people
are more likely to help tight social groups than loose ones, a possibility that is somewhat
surprising given that the gazelle in a herd at least have each other as support. These
results are consistent with our theory that entitativity affects people’s perceptions of
victims and emotional reactions. One alternative interpretation is that these results may
also be driven by inferences participants might make regarding the efficacy and impact of
their donations. People tend to donate more generously as the reference group to which
the victims belong grows smaller and the proportion helped thus increases (Slovic,
Fischhoff, & Lichtenstein, 1980). For instance, a disease that kills 100 people out of a
group of 100 seems more severe and worthy of response than a disease that kills 100
across a country (Small & Loewenstein, 2003). It is possible that the herd may act as its
own reference group and donations to help it seem more impactful, but that the unrelated
gazelle do not and donations to them are perceived as mere drops-in-the-bucket (Bartels
and Burnett 2010; Singer 1972). The mediating role of emotions in the previous study
provides some evidence against this account. The next study addresses it more directly by
employing a perceptual manipulation of entitativity.
Study 1b: Increasing Donations through Perceptual Entitativity
Research shows that looking at the entire Gestalt of a stimulus configuration
results in a search for similarities in a subsequently viewed stimulus set (Förster, 2009;
8
THE INFLUENCE OF ENTITATIVITY ON CHARITABLE GIVING
Förster, Liberman, & Kuschel, 2008). Perceived similarity of targets is a key feature of
entitativity; priming Gestalt processing should therefore encourage participants to see
subsequent targets as more entitative, and to donate more generously. Because the
reference group herd is not mentioned, this type of manipulation should not affect
participants’ inferences about the proportional impact of their donations.
Method
Eighty-one participants from a large Midwestern-USA university completed a
modified Navon task that primes Gestalt versus piecemeal processing (Förster & Higgins,
2005; Förster, 2009; Navon, 1977). On the computer, participants were presented with a
series of “global” letters made up of smaller “local” letters. Over 48 trials, half were
tasked with identifying only the global letters (Gestalt condition) and half with
identifying only the local letters (piecemeal condition). (Specific details can be found in
Förster, 2009.) All participants were then presented with the 200 unrelated gazelle
scenario from Study 1a and asked for their hypothetical donation on a scale from $0 to
$55.
Results and Discussion
As predicted, Gestalt-primed participants donated more to save the 200 gazelle, M
= $14.26, SD = 16.62, than piecemeal-primed participants, M = $7.50, SD = 9.71, t(79) =
2.12, p = .037, d = .50. Similar results were found for the medians. These results support
our argument that entitativity can lead to higher donations. Donations to save 200 gazelle
were higher when they were made perceptually entitative through a Gestalt processing
prime, just as when they were conceptually entitative as a herd.
Study 2: Good Kids Versus Bad: When Entitativity Reduces Donations
9
THE INFLUENCE OF ENTITATIVITY ON CHARITABLE GIVING
We have hypothesized that perceived entitativity causes stronger emotional
responses to a group with positive traits and hence more concern. For groups with
negative defining traits, entitativity should dampen concern, with unfortunate
implications for donations. Study 2 provides a test of this hypothesis. It also explicitly
measures entitativity and employs actual donations.
Method
Participants were 231 students from a large Midwestern-USA university who
completed this survey immediately after they were paid $15 for an unrelated experiment.
Participants read that a $300,000 facility was required to provide necessary training and
education for children in Africa. We employed a three (presentation) by two (valence)
between-participants design. The presentation factor was manipulated by the focus of the
donation appeal: a single child, six children, or six children that belonged to the same
family (six siblings). We replicated Kogut and Ritov’s method of identifying the victims
with names and pictures. Group portraits were used for the multiple victim conditions,
with identical portraits for the six children and family conditions. Pictures of single
children cut out from the group portrait were randomly assigned for the single victim
conditions (see Kogut & Ritov, 2005a, for a description). The valence factor was
manipulated by emphasizing positive traits of children in Africa or negative traits of
children in Africa that were in a prison for committing crimes. In both conditions
participants read that the facility was required to provide necessary training and education
for these children and other children like them.
Participants were asked how much of their $15 they would be willing to donate to
fund the facility on a scale from $0 to $15 in $1 increments. After the donation decision,
10
THE INFLUENCE OF ENTITATIVITY ON CHARITABLE GIVING
participants reported their concern using the measures from Study 1a. These responses
and donation amounts were completely anonymous: Participants filled out the survey, put
it and their donation in an unmarked envelope, and left it in a box as they exited the
room. All money was delivered by the experimenter to the charitable organization.
Results and Discussion
We confirmed that the family presentation increased perceived entitativity by
asking 118 students to rate the children in the scenario on eight questions used by Brewer
et al. (2004) that tap into Campbell’s (1958) definition of entitativity (e.g. “To what
extent do you believe that the [victims] should be thought of as a whole, rather than a
collection of individual members?”). Participants provided estimates on 1 (not at all) to 9
(extremely) scales. These questions, which were originally designed to measure
entitativity of groups, do not easily lend themselves to the single victim contexts.
Therefore, we collected entitativity measures only for the family and unrelated children
conditions. As predicted, the combined measures (α = .85) differed by presentation
condition: Both negatively and positively-valenced children were perceived as more
entitative when they were presented as siblings than when they were not, F(1, 114) =
9.96, p = .002, ηp2 = .08. There was not an interaction of presentation by valence on the
measure of entitativity.
A pretest of how beautiful, pleasant, and good (α = .85) participants imagined the
victims in each condition revealed that, as expected, children in the positive valence
condition were seen as more positive than child-prisoners (see Figure 2), F(1, 216) =
20.30, p < .001, ηp2 = .09. More important, we found an interaction of presentation and
valence, F(2, 216) = 7.61, p = .001, ηp2 = .07. Contrasts revealed that the family of six
11
THE INFLUENCE OF ENTITATIVITY ON CHARITABLE GIVING
children in the positive-valence condition was judged more positively than the unrelated
six children, F(1, 216) = 9.01, p = .003, as was the single child, F(1, 216) = 8.04, p
= .005. However, in the negative valence condition, the family was judged marginally
more negatively than the unrelated six children, F(1, 216) = 3.14, p = .078, as was the
single child, F(1, 216) = 3.95, p = .048.
A relatively small proportion (43% on average) of participants chose to donate in
this experiment. Therefore, we analyzed the data using a Tobit model (Amemiya, 1985;
Greene, 2003), examining the extent to which the presentation of the victims (one, six, or
six siblings in a family) and their valence (positive or negative) affected donations. The
Tobit model was run with zero (no donation) and 15 (total dollar donation available) as
the lower and upper limits, respectively. The results are presented in Table 1 and are
nearly identical to those obtained with a linear regression.
We are mainly interested in the interaction between how the six children were
presented (unrelated versus entitative) and valence on donations. As predicted, the
interaction between presentation and valence was significant, β = 2.55, t(225) = 2.80, p
= .006. To explore this interaction further, we examined the effect of presentation as a
family for positive and negative victims separately. In the positive valence condition, six
entitative children elicited significantly greater donations than six unrelated children, β =
2.72, t(108) = 1.91, p = .030. In contrast, six negatively-valenced children elicited
significantly lower donations when entitative than when unrelated, β = -1.94, t(117) =
2.10, p = .038. We also replicated previous findings for positive valence victims:
Participants donated significantly less money to six unrelated children than a single child
12
THE INFLUENCE OF ENTITATIVITY ON CHARITABLE GIVING
(Kogut & Ritov, 2005a; 2005b). Donations for one and six unrelated children in the
negative valence condition were virtually identical.
As in our previous mediation analysis, we looked at the two entitative conditions
together (within valence, neither concern nor donations significantly differed based on
single vs. family presentation, p’s > .09) and confirmed that concern (α = .79) mediated
the interactive effect of valence by presentation on donations, Sobel Z = 1.93, p = .053.
These results support the entitativity explanation for our presentation effects and
reveal a limit to the positive consequences of perceived entitativity on real donations: As
predicted, participants donated less to entitative negative victims than unrelated negative
victims. We also showed that the interactive effect of presentation and valence on the
donation amount was mediated by participants’ concern for the victims, illustrating once
again that the concern that promotes charitable giving is driven by the valence and
entitativity of the victim(s).
General Discussion
Our three experiments show that people donate more to large numbers of victims
if these victims make up an entity. We suggest that entitativity increases the strength and
coherence of victims’ defining traits. Thus, victims with positive traits are viewed more
positively when entitative, increasing concern and donations. However, entitative victims
that share negative traits have the opposite effect, producing lower concern and donations
than for unrelated victims. As we have already argued, a change in the perception of the
reference group is not a viable alternative explanation for this effect. Recall that the
results of Study 1b, which relied on a perceptual manipulation of entitativity, rule out this
possibility. We also doubt the reference group explanation of our findings because it
13
THE INFLUENCE OF ENTITATIVITY ON CHARITABLE GIVING
cannot easily account for the reversal of the effects of entitativity on donations for
victims with negative traits and for more extreme perceptions of the traits defining
entitative victims.
Recent work in this area has described the tragically muted response to multiple
victims as pervasive and impossible to repair. Slovic (2007, p. 91) writes, “Are we
destined to stand numbly and do nothing as genocide rages on for another century? Can
we overcome the psychological obstacles to action? There are no simple solutions.” Our
experiments provide some hope for resolving this problem; increase the entitativity of
large groups. For instance, rather than describing the millions of victims of malaria each
year, the appeal could describe the impact of malaria on the “country” or “village” level.
In this sense, our theory provides a solution through a bias. Small et al. (2007)
point out that it is the elevated reaction to single victims that is a bias, albeit a socially
beneficial one (see also Thaler & Sunstein, 2008). These authors show that attempts to
debias participants backfire: They reduce donations to the single identified victim. Our
results imply an intervention that does not lower donations to single victims but rather
increases reactions to multiple victims through re-biasing. However, our findings also
illustrate that the bias is not necessarily beneficial; instating the bias for groups with
negative traits lowers concern and donations.
The reversal in the effect of entitativity on donations to negatively versus
positively-valenced victims has practical as well as theoretical significance because
appeals to help victims with negative characteristics may not be uncommon: Victims are
rarely composed of only positive traits, and even victims who are viewed as positive by
some people may be viewed as negative by others. Similarly, a person’s attention will
14
THE INFLUENCE OF ENTITATIVITY ON CHARITABLE GIVING
sometimes be drawn to the positive aspects and other times to the negative aspects of the
donation target. Depending on these factors, entitativity will trigger very different effects.
This research both directly contributes to research on charitable giving to multiple
victims and also joins a growing body of research on biases in valuation. That is, our
results reconcile the seemingly discrepant findings regarding the impact of identification
of groups on donations described in the introduction, show that the identified victim
effect generalizes to entitative groups, and suggest that Kogut and Ritov’s (2005a; 2005b)
decreasing donations for more identified victims can be attributed to decreasing
entitativity. Our findings also contribute to a more general study of valuation and scope.
For instance, Burson, Faro, and Rottenstreich (2010) find that the endowment effect
occurs only when people are endowed with a single unit of a good. They demonstrate that
a unit can be a single good or multiple goods that have been packaged together. For
example, they find an endowment effect for one chocolate, but not for 10 chocolates.
When 10 chocolates were packaged together in a box, however, the endowment effect
reemerges. Though quite different demonstrations, these two papers imply that presenting
people with an entitative unit produces biased judgments.
We opened this paper with an iconic example of a single victim, the photographed
Afghan girl, eliciting overwhelming prosocial behavior. In light of our results, we argue
that the strong reaction to this single victim may be in part driven by entitativity and that
even very large groups of victims might elicit similar responses if perceived as
sufficiently entitative. Al Gore makes a similar point in his book (2006). He quotes the
author Archibald MacLeish who wrote after seeing the first picture of the Earth from
space: “To see the Earth as it truly is, small and blue and beautiful in that ethereal silence
15
THE INFLUENCE OF ENTITATIVITY ON CHARITABLE GIVING
where it floats, is to see ourselves riders on the Earth together, brothers on that bright
loveliness in the eternal cold—brothers who know now that they are truly brothers.” Gore
argues that MacLeish and others were so moved by this photograph that it spawned the
Environmental Movement. We add that the entitativity of the Earth presented this way
may contribute to such reactions.
