Dissonance Reduction

After deciding among options, decision makers exhibit an increased positive evaluation of the chosen option coupled with a decreased evaluation for those rejected, resulting in a spreading of alternatives (SoA). There has been a longstanding debate as whether SoA results from post-choice dissonance reduction, or whether it plays an instrumental role in reaching a decision. Here we introduce a novel procedure that measures SoA implicitly during the process of choice. Participants provided simultaneous value ratings for the options on offer on each trial before finalizing their choice. The results clearly demonstrate that SoA occurs before choices are finalized. Furthermore, SoA is instrumental to the choice process: it enhances choice consistency and confidence and reduces response time. The SoA generated during choice is transient in nature, partially regressing toward baseline shortly afterwards.

Trait Factors

Many rational choice theories posit that rational decision makers assign subjective values to all available choice options and choose the option with highest subjective value. Choice options are usually composed of multiple attributes, e.g. healthiness and taste in dietary choice or risk and expected returns in financial choice. These attributes have to be integrated into a single subjective value. Subjective value maximizing choice requires choice consistency, i.e. consistent weighing of the choice attributes across choices. However, empirical work suggests that perfect choice consistency is often violated, for example when decision makers weigh choice attributes differently across multiple decisions. Some researchers propose to extend certain bounds of rationality or to abandon the concept of rationality as adherence to consistency principles altogether. A more conservative stance assumes that perfect consistency can be violated by decision makers in practice, but that consistency principles still can explain large parts of behavior. In a review of the recent literature, we identify factors for compromised consistency relative to baseline conditions. Broadly, we distinguish between undynamic trait factors and fluid state factors. We find evidence for an influence of age, education, intelligence, and neurological status. In contrast, choice consistency appears to be relatively robust to the influence of sex, personality traits, cognitive load, sleepiness and blood alcohol levels. We conclude, that, according to the current state of the literature, only fundamental differences in decision makers, that is, trait differences, have a significant impact on choice consistency.

Instrumental Role

Neo-functionalism ascribes a dynamic role to interest groups in the process of integrating pluralist communities. By participating in the policymaking process, interest groups are expected to develop a stake in promoting further integration in order to acquire economic payoffs and additional benefits from maintaining and stimulating the organization through which certain demands can be articulated and goals attained. This implies that in the integration process interest groups have an instrumental role to play in the maintenance of the system; and that by virtue of their participation in the policy-making process of an integrating community they will “learn” about the rewards of such involvement and undergo attitudinal changes inclining them favorably towards the system. Thus, they acquire an interest in seeing the system's perpetuation, and the policy and decision makers acquire an interest in being responsive to interest groups' demands. What is implied overall is that actors' loyalties will shift towards those decision makers in the systems best able to reward them.

Abstract. This study combines AHP and GIS to provide decision makers with a model to ensure optimal site location(s) for fire stations selected. The roles of AHP and GIS in determining optimal locations are explained, criteria for site selection are outlined, and case study results for finding the optimal fire station locations in Istanbul, Turkey are included. The city of Istanbul has about 13 million residents and is the largest and most populated city in Turkey. The rapid and constant growth of Istanbul has resulted in the increased number of fire related cases. Fire incidents tend to increase year by year in parallel with city expansion, population and hazardous material facilities. Istanbul has seen a rise in reported fire incidents from 12 769 in 1994 to 30 089 in 2009 according to the interim report of Istanbul Metropolitan Municipality Department of Fire Brigade. The average response time was approximately 7 min 3 s in 2009. The goal of this study is to propose optimal sites for new fire station creation to allow the Fire Brigade in Istanbul to reduce the average response time to 5 min or less. After determining the necessity of suggesting additional fire stations, the following steps are taken into account: six criteria are considered in this analysis. They are: High Population Density (HPD); Proximity to Main Roads (PMR); Distance from Existing Fire Stations (DEF); Distance from Hazardous Material Facilities (DHM); Wooden Building Density (WBD); and Distance from the Areas Subjected to Earthquake Risk (DER). DHM criterion, with the weight of 40%, is the most important criterion in this analysis. The remaining criteria have a weight range from 9% to 16%. Moreover, the following steps are performed: representation of criterion map layers in GIS environment; classification of raster datasets; calculating the result raster map (suitability map for potential fire stations); and offering a model that supports decision makers in selecting fire station sites. The existing 35 fire stations are used and 17 fire stations are newly suggested in the study area.

Data warehouse has become an integral part in developing a DSS in any organization. One of the key architectural issues concerning the efficient design of a data warehouse is to determine the “right” number of views to be materialized in order to minimize the query response time experienced by the decision makers in the organization. We consider a bottleneck objective in designing such a materialization scheme which has the effect of guaranteeing a certain level of performance. We examine linear integer programming formulations, and develop heuristics and report on the performance of these heuristics. We also evaluate heuristics reported in the literature for the view materialization problem with a simpler objective.

Choice-consistency is considered a hallmark of rational value-based choice. However, because the cognitive apparatus supporting decision-making is imperfect, real decision-makers often show some degree of choice inconsistency. Cognitive models are necessary to complement idealized choice axioms with attention, perception and memory processes. Specifically, compelling theoretical work suggests that the (imperfect) retention of choice-relevant memories might be important for choice-consistency, but this hypothesis has not been tested directly. We used a novel multi-attribute visual choice paradigm to experimentally test the influence of memory retrieval of exemplars on choice-consistency. Our manipulation check confirmed that our retention interval manipulation successfully reduced memory representation strength. Given this, we found strong evidence against our hypothesis that choice-consistency decreases with increasing retention time. However, quality controls indicated that the choice-consistency of our participants was non-discernable from random behaviour. In addition, an exploratory analysis showed essentially no test–retest reliability of choice-consistency between two observations. Taken together, this suggests the presence of a floor effect in our data and, thus, low data quality for conclusively evaluating our hypotheses. Further exploration tentatively suggested a high difficulty of discriminating between the choice objects driving this floor effect.

Specific Influence

Neoclassic economic choice theory assumes that decision-makers make choices as if they were rational agents. This assumption has been critically challenged over the last decades, yet systematic aggregation of evidence beyond single experiments is still surprisingly sparse. Here, we asked how robust choice-consistency, as a proxy for rationality, is to endogenous and exogeneous factors. To this end, we conducted a systematic quantitative literature research, reviewing 5327 articles, identifying 44 as relevant that contained hypothesis tests on possible influence factors of choice-consistency. To assess the evidential value of any effect of such influence factors on choice- consistency, we conducted a robust p-curve analysis. Our results indicate that choice-consistency is affected by endogenous or exogeneous factors. This result holds for multiple testing procedures and a robustness check. However, due to the breadth of the contemporary research agenda, the lack of replications and the unavailability of original data in the field of choice-consistency, it is currently not possible to draw meaningful conclusions regarding specific influence factors. Despite this lack of specificity, our results implicate that people’s decisions might be a noisier and more biased indicator of their underlying preferences than previously thought. Hence, we provide systematic evidence for the wide-spread belief that rationality cannot be assumed unconditionally.

After having been told they were free to accept or refuse, pupils aged 6–7 and 10–11 (tested individually) were led to agree to taste a soup that looked disgusting (phase 1: initial counter-motivational obligation). Before tasting the soup, they had to state what they thought about it. A week later, they were asked whether they wanted to try out some new needles that had supposedly been invented to make vaccinations less painful. Agreement or refusal to try was noted, along with the size of the needle chosen in case of agreement (phase 2: act generalization). The main findings included (1) a strong dissonance reduction effect in phase 1, especially for the younger children (rationalization), (2) a generalization effect in phase 2 (foot-in-the-door effect), and (3) a facilitatory effect on generalization of internal causal explanations about the initial agreement. The results are discussed in relation to the distinction between rationalization and internalization.

In Europe, micronutrient dietary reference values have been established by (inter)national committees of experts and are used by public health policy decision-makers to monitor and assess the adequacy of diets within population groups. The approaches used to derive dietary reference values (including average requirements) vary considerably across countries, and so far no evidence-based reason has been identified for this variation. Nutrient requirements are traditionally based on the minimum amount of a nutrient needed by an individual to avoid deficiency, and is defined by the body’s physiological needs. Alternatively the requirement can be defined as the intake at which health is optimal, including the prevention of chronic diet-related diseases. Both approaches are confronted with many challenges (e. g., bioavailability, inter and intra-individual variability). EURRECA has derived a transparent approach for the quantitative integration of evidence on Intake-Status-Health associations and/or Factorial approach (including bioavailability) estimates. To facilitate the derivation of dietary reference values, EURopean micronutrient RECommendations Aligned (EURRECA) is developing a process flow chart to guide nutrient requirement-setting bodies through the process of setting dietary reference values, which aims to facilitate the scientific alignment of deriving these values.
