One of the most cited persuasion studies but no success in replication: investigating replication using Petty, Cacioppo, and Goldman (1981) as an example

Scientific progress depends on replication even though replications are generally not recognized for their research contributions. Recently many behavioral sciences have paid a great deal of attention to replications, but replications are infrequent and not generally discussed in communication science. The present study conducts a replication of Petty, Cacioppo, & Goldman, 1981 (PCG) as an example. PCG is one of the best known studies on persuasion, but the discrepancies between PCG's and similar studies’ findings have been cumulating. Our study discusses these discrepancies, which have implications for the validity of the elaboration likelihood model and for replications in communication science more generally.
