Dynamics of Public Service Motivation: Attraction‒Selection and Socialization in the Production and Regulation of Social Services

The literature on public service motivation (PSM) has typically focused on the relationship between motivation and public/private sector of employment, while the character of the work being performed has been neglected. Using panel surveys with pre‐ and postentry measures of PSM among certified Danish social workers, this article provides a unique design for investigating PSM‐based attraction?selection and socialization effects with respect to the choice between work related to service production or service regulation (controlled for public/private sector of employment). The article shows that the PSM profiles of social work students predict their preference for one of the two types of work tasks but do not predict first employment in the preferred job. Conversely, postentry shifts in social workers’ PSM profiles result from a complex interplay between influences from both work task and sector.     

Effects of an Alibi Witness’s Relationship to the Defendant on Mock Jurors’ Judgments

Two studies tested the impact of an alibi witness’s relationship to a defendant on the perceived credibility of that witness. In the first study, 291 mock jurors estimated the frequency with which individuals would invent alibis, the frequency they themselves would do so, and the frequency of interpersonal contact among individuals of varying relationships. The degree of relationship between an alibi witness and a defendant remained a predictor of witness credibility when contact frequency was controlled. In the second study, 512 mock jurors were randomly assigned to case scenarios. Skepticism toward witnesses who are biologically or affinally related to a defendant was greater than skepticism toward a socially linked witness. Both studies supported predications from kinship theory and reciprocal altruism.
