Men a request is preceded by a casual dialogue, the approached person is mo
re likely to comply than when the same request follows a monologue. This ef
fect appeared to be strong and replicable in a series of field studies. Acr
oss experiments, the issues discussed in conversations between the confeder
ates and the participants and the nature of the critical request varied, su
ggesting that the effect is generalized. In social situations, the two basi
c modest of communication (dialogue and monologue) are characteristic of di
fferent types of interactions, Dialogue is characteristic of encounters wit
h one's friends and acquaintances, whereas monologue is more prevalent in c
ontacts with strangers. As a result of social learning, a dialogue makes us
prone to treat a stranger as someone we know and thus become more eager to
comply with her or his requests. Although the results obtained in the stud
ies are consisted with this model, alternative explanations and limitations
of the research also are discussed.
