We present a model of opinion formation where individuals repeatedly engage in discussion and update their opinion in a social network similarly to the DeGroot model. Abstracting from the standard assumption that individuals always report their opinion truthfully, agents in our model interact strategically in the discussion such that their stated opinion can differ from their true opinion. The ...

Is the variety of products supplied in markets a reflection of the diversity of consumers’ preferences? In this paper, we argue that the distribution of durable goods offered in markets tends to be compressed relative to the distribution of consumers’ underlying preferences. In particular, there are strong incentives for conformity in markets for durable goods. The reason for conformity is natu...

Patterns of conforming behavior were compared for Ss empirically contrasted as conservatives, moderates, or liberals on a politically based Thurstone-type scale. In a split-plot factorial analysis-ofvariance design, liberalism-conservatism of the Ss and political identification of the influence sources were employed as between-Ss variables, while task difficulty opera ted as a within·Ss variabl...

Event-related potentials (ERPs) were used in this study to explore the neural mechanism of obedience and conformity on the model of online book purchasing. Participants were asked to decide as quickly as possible whether to buy a book based on limited information including its title, keywords and number of positive and negative reviews. Obedience was induced by forcing participants to buy books...

When presented with responses of another person, people incorporate these responses into memory reports: a finding termed memory conformity. Research on memory conformity in recognition reveals that people rely on external social cues to guide their memory responses when their own ability to respond is at chance. In this way, conforming to a reliable source boosts recognition performance but co...

In three experiments we tested the conformity hypothesis--that subjects' ideas would conform to examples they had been shown--by using a creative generation paradigm in which subjects imagined and sketched new exemplars of experimenter-defined categories. Designs made by subjects who had first seen three examples of ideas were compared with those of control subjects, who received no examples. I...

OBJECTIVES This study aims to establish a "Vertigo Council Diagnosis Questionnaire" for patients with chronic vestibular dysfunction and show the reliability of this questionnaire. MATERIALS AND METHODS A "Vertigo Council Diagnosis Questionnaire" consisting of 10 questions was prepared by 15 specialist physicians and analyzed for reliability using the "translation-back-translation" method. ...

Epidemiological models have been applied to human health-related behaviors that are affected by social interaction. Typically these models have not considered conformity bias, that is, the exaggerated propensity to adopt commonly observed behaviors or opinions, or content biases, where the content of the learned trait affects the probability of adoption. Here we consider an interaction of these...
