Consumer judgment often is based on incomplete or limited knowledge of the relevant attributes. We performed 3 experiments to investigate why these judgments are often insensitive to set size and why evaluations based on limited information tend to be stronger (more extreme and confident) than is warranted. The findings indicate that the importance of the given or known attributes is often overestimated, leading to evaluations that are overly extreme. The experiments also revealed important factors moderating this insensitivity to limited information. The overweighing of the given evidence was attenuated when participants were knowledgeable of the target domain. Overweighing and the formation of extreme judgments based on limited information was also diminished when participants considered their judgmental criteria prior to evaluating a target or when a comparison target described by different attributes was present.Judgment often requires the gathering, assessment, and integration of multiple pieces of information. The evaluation of job candidates, for example, entails the summarization of evidence about the various qualifications of each applicant. Automobile assessments similarly require the integration of knowledge about various features such as styling, engine size, and repair record.

Hox genes are critical regulators of skeletal development and Hox9-13 paralogs, specifically, are necessary for appendicular development along the proximal to distal axis. Loss of function of both Hoxa11 and Hoxd11 results in severe malformation of the forelimb zeugopod. In the radius and ulna of these mutants, chondrocyte development is perturbed, growth plates are not established, and skeletal growth and maturation fails. In compound mutants in which one of the four Hox11 alleles remains wild-type, establishment of a growth plate is preserved and embryos develop normally through newborn stages, however, skeletal phenotypes become evident postnatally. During postnatal development, the radial and ulnar growth rate slows compared to wild-type controls and terminal bone length is reduced. Growth plate height is decreased in mutants and premature growth plate senescence occurs along with abnormally high levels of chondrocyte proliferation in the reserve and proliferative zones. Compound mutants additionally develop an abnormal curvature of the radius, which causes significant distortion of the carpal elements. The progressive bowing of the radius appears to result from physical constraint caused by the disproportionately slower growth of the ulna than the radius. Collectively, these data are consistent with premature depletion of forelimb zeugopod progenitor cells in the growth plate of Hox11 compound mutants, and demonstrate a continued function for Hox genes in postnatal bone growth and patterning.
There are many instances of consumer decision making in which more consideration is given to 1 brand than to others in the choice set. This research explored how selective consideration of a brand affects attitudes toward the brand, relative standing of the focal brand within the choice category, and decision making. Experiment 1 demonstrated that when participants were prompted to consider a randomly determined focal alternative, that alternative was more likely to be chosen than nonfocal alternatives. Moreover, willingness to pay for an alternative was higher if it was the focus of consideration. Attitudinal data suggest that the selective consideration effect occurred because attitudes toward the focal alternative became more positive compared to those toward other alternatives in the choice set. Experiment 2 elucidated this attitudinal effect by demonstrating that selective consideration could cause the extremity of consumers' attitudes toward a focal brand to become more positive. Experiment 3 explored the potential of the selective consideration of a focal alternative to influence the consistency between consumers' attitudes and decisions and established that the initial attitude toward a focal alternative moderated the selective consideration effect.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
