The Legitimization of Paltry Favors Effect: A Review and Meta-Analysis

A meta-analysis was conducted on the legitimization of paltry favors (LPF) effect (Cialdini & Schroeder, 1976). A total of 19 studies met the inclusion criteria, with a combined sample of 2,730 subjects. Excluding studies in which the LPF request was delivered via mail and those studies that accepted pledges as the dependent variable resulted in a homogeneous set of effect sizes (r = .18, OR = 2.41). While the data provide clues as to possible mediating mechanisms, the cause of the effect is still not clear. Directions for future research are suggested.

Employing interpersonal influence to promote multivitamin use.

Boster, Kotowski, Andrews, and Serota (2011) proposed that superdiffusers are well connected, persuasive, and a maven in a content area. They proposed that superdiffusers, if recruited, could promote the adoption of health practices. In this article a model of this process is presented, and an intervention designed to test the efficacy of this influence strategy is introduced. Specifically, superdiffusers were recruited to persuade their peers to take a daily multivitamin. Evidence was found consistent with the interventions effectiveness.

Do Superdiffusers Argue Differently? an Analysis of Argumentation Style as a Function of Diffusion Ability

Boster et al.s (2006) dimensions of diffusion ability were used to determine if the argumentation of superdiffusers of health information (those who are well-connected, persuasive, and knowledgeable about healthy lifestyles) is different from those who are not. In Study 1, 164 undergraduates completed the measures of diffusion ability. They were then asked how they would try to persuade a target either to lose weight or to avoid smoking. The scenario they were given was either simple or complex. For the participants who responded to the avoiding smoking scenario a 2 (superdiffuser or not) X 2 (scenario complexity: simple or complex) interaction was found such that superdiffusers who responded to the complex scenario produced more arguments, more overall themes in their arguments, and addressed more elements of the scenario than any of the other three groups. Superdiffusers produced more arguments when they responded to the weight loss scenario. A second study was conducted with 35 participants who were interviewed about their beliefs on dieting. Their responses were coded for argument complexity. Superdiffusers produced more complex arguments than non-superdiffusers. In sum, results indicated that superdiffusers argue in ways that would facilitate the effective diffusion of health information.
