Abstract
-
The purpose of the present study is to replicate as closely as possible the study titled
“Friendship as a Relationship Infiltration Tactic during Human Mate Poaching”
(Mogilski & Wade, 2013). The purpose of the replication was to further explore the well
documented lack of replications within psychology, and to provide a template for how to
improve this issue. The authors of the original study sought to determine how friendship
affected the success of someone trying to infiltrate a romantic relationship. They
hypothesized that a person would be more likely to successfully steal the mate of another
if the poacher was friends with their target mate, rather than acquaintances. When the
poacher/poached were friends previous to the attempt, it was hypothesized that the
poacher would incur fewer costs (e.g., physical retaliation from the poachee). Participants
were given one of four vignettes to read then asked to rate the poacher’s likelihood of
being successful and incurring future costs. Data was analyzed using a 2(sex) x
2(friendship) Multivariate Analysis of Variance. Overall, the replication study provided
supporting evidence for all but one hypothesis. However, only the first (regarding success
rate) was replicated successfully in that it was the only statistically significant result that
overlapped with the original study. The implication of these conflicting results shows the
importance of replication within psychology.
