Zur Analyse des Bumerang-Effektes

Zusammenfassung In zwei Experimenten wurde mit Hilfe unterschiedlicher sozialer Attitüden und Werthaltungen jeweils die Hypothese geprüft, daß sich Einstellungen nach einstellungskonträrer Agitation in Richtung dieser Agitation oder aber nicht und in Gegenrichtung zur Agitation ändern, je nachdem ob sie weniger oder mehr in allgemeineren Werthaltungen verankert sind. Im Rahmen einer um die Konzeption der Verankerung erweiterten Theorie der kognitiven Dissonanz können damit besser als bisher sogenannte Bumerang-Effekte bei Änderungen von Attitüden erklärt werden.

Summary In two experiments we tested the following hypothesis concerning social attitudes and value orientations: Attitudes will be changed after counter-attitudinal agitation in the direction of this agitation or in opposite direction depending on their degree of being anchored in general value orientations. With the theory of cognitive dissonance, supplemented by the conception of anchoring, we are now able to explain better than before the so-called boomerang-effects which appear with attitude changes.

     

Simulation of Preference Information in an Interactive Reference Point‐Based Method for the Bi‐Objective Inventory Routing Problem

In the research area of multiple criteria decision making, very few publications exist that explicitly design the simulation of a decision maker (DM) in an interactive approach. For this reason, we outline some methods widely used in the literature to identify common assumptions of simulating the DM's responses and the required input preference information. Our paper aims at covering the identified gap by introducing experimental concepts. Such concepts are used for theoretical analyses of a combined search‐and‐decision‐making procedure. Simulating the DM is a fruitful idea because the algorithm can be tested without integrating a human decision maker. Finally, we conduct experiments based on the proposed settings for a multiobjective inventory routing problem, which is a relevant and challenging logistic problem.
