EXTENDED ABSTRACT
Consumers perceive Word-of-Mouth information (WOM) as
more credible than marketer-originated information (Bickart and
Schindler 2001). Consequently, extant research focused on the
antecedents and outcomes of WOM, and the question of what
information consumers exchange with others (depending on “why”,
“about what”, and “to whom” they are talking) has not received
much research attention. It has been commonly assumed that
people engage in WOM to improve quality of decisions, and thus,
exchange diagnostic information to reduce their uncertainty with
respect to offerings (Herr, Kardes and Kim 1991). Recent research
indicates that people also engage in WOM to establish social
connections (Sassenberg 2002). This paper aims to demonstrate
that the social bonding goal increases the value of engaging market-
ing information in WOM. In our context, information is considered
as socially engaging whenever it spurs shared emotions among
communicators (e.g., funny or interesting information). More im-
portantly, we also demonstrate that social-bonding efforts in WOM
depend on “to whom” (e.g., friends vs. acquaintances) and “about
what” people could talk (e.g., nature of marketing information).
According to our theoretical framework, people make trade-
offs between different communication goals, depending on the
characteristics of available topics and relationships among the
communicators. Availability of highly engaging topics stimulates
the social- bonding goal, and availability of relatively significant
incentives resulting from attending to informative topics, facilitates
the uncertainty reduction goal. Similarly, establishing social bonds
via talking about engaging marketing information might be more
prevalent among people with weak social-ties than among people
with strong-social ties, especially when the given information is not
about product benefits, and thus, does not trigger conversations
about intimate consumption experiences (e.g., a funny joke in an
advertisement). That is, impersonal marketing information might
be a good conversation topic among strangers who lack other
common topics. Lastly, we assume that goals influence selection of
particular topics for conversations; therefore, observed bias for
engaging information in social settings is an indication of the social
bonding goal. More specifically, we predict that:
H1: Engaging information becomes significantly more valu-
able when it is consumed socially than when it is con-
sumed individually.
H2: Acquaintances that are in need of social connections are
more likely to promote the social bonding goal via
engaging conversations about marketing information
than other goals.
H3: The choice of engaging option increases over time during
the WOM episode and conversations at early stages of a
WOM episode exert disproportional influence on later
choices.
We applied an experimental paradigm in which participants
were asked to choose between furniture and personal ads for
proofreading to earn between $5 and $9, depending on the number
of misspelled words they could identify over ten trials. Furniture
and personal ads had, respectively, seven and three misspelled
words. The task required participants to make a tradeoff between
engaging conversations with others and their individual earning/
savings as in consumer choice between discount ads and humorous
ads. Furthermore, although participants were told in advance that
furniture ads had more spelling mistakes and that personal ads were
more interesting, they did not know the exact number of spelling
errors; nor did they know how much more interesting personal ads
were relative to furniture ads. Finally, there were two independent
conditions in the study: subjects made their choices either privately
or together with three other participants, in which case they could
talk about the ads. All participants distributed 100 points between
the spelling-error rate and the content to reflect the importance of
these attributes in their choice of ads at the end of the study and
indicated the number of people they were friends with in their
group. All conversations were audio-taped for further content
analysis.
Data support our predictions (p<.05). In general, engaging
information became significantly more valuable when it was con-
sumed socially than when it was consumed individually (H1) and
the advantage of engaging information in social setting increased in
conversations with weak ties (H2). More specifically, the impor-
tance of the content in making choices was significantly larger in
the WOM condition than in the individual condition, suggesting
that WOM participants intentionally shifted their goals in the
direction of the social bonding goal. The intentional shift was larger
for acquaintances than for friends. Also, WOM participants talked
about the most relevant information for decisions, the spelling-error
rate/money, only 23% of the time despite the fact that the impor-
tance of the spelling-error rate in making their choices was 42%.
Note that the importance of money in the individual condition was
68%. That is, WOM groups deliberately switched their interest or
preferences in favor of content, but they conversed about money
even less than what would be expected given the intentional shifts
in goals. In contrast to the conversations about money, intentional
shifts determined the frequency of conversations about personal
ads to a great extent; participants talked about personal advertise-
ments 60% of the time and the importance of the content was 58%
(32% for individuals); however, conversations systematically di-
verged from the intentional shifts in goals depending on the social
ties. In particular, exclusively-acquaintance (mean=0.74) and ex-
clusively-friend (mean=0.66) groups talked about the personal
advertisements significantly more than the mixed groups
(mean=0.56) did. Also, exclusively-friends groups talked about
personal advertisements less than they intended to whereas exclu-
sively-acquaintance groups talked about personal advertisements
more than they intended to. Furthermore, WOM participants chose
personal ads more than they intended to, compared with individu-
als. While the individual goal determined the initial choices, later
choices were governed by the goal of the group and the nature of the
conversations during the early stages of communications (H3).
Overall, our results suggest that WOM participants herd into
engaging options disproportionately more with conversations over
time in comparison to the individual decision-makers. Further-
