Sampling in Judgment and Decision Making
Sampling approaches to judgment and decision making are distinct from traditional accounts in psychology and neuroscience. While these traditional accounts focus on limitations of the human mind as a major source of bounded rationality, the sampling approach originates in a broader cognitive-ecological perspective. It starts from the fundamental assumption that in order to understand intra-psychic cognitive processes one first has to understand t…
Networks of Beliefs
We present a theory of belief dynamics that explains the interplay between internal beliefs in people’s minds and beliefs of others in their external social environments. The Networks of Belief theory goes beyond existing theories of belief dynamics in three ways. First, it provides an explicit connection between belief networks in individual minds and belief dynamics on social networks. The connection, absent from most previous theories, is esta…

Integrating social and cognitive aspects of belief dynamics
Belief change and spread have been studied in many disciplines-- from psychology, sociology, economics and philosophy, to computer science and statistical physics-- but we still do not have a firm grasp on why some beliefs change and spread easier than others. To fully capture the complex social-cognitive system that give rise to belief dynamics, we need to integrate the findings of these disciplines into a single framework. Communication between…
Public perceptions of how to reduce carbon footprints of consumer food choices
Carbon footprints—the greenhouse gas (GHG) emissions associated with consumer food choices—substantially contribute to climate change. Life cycle analyses from climate and environmental sciences have identified effective rules for reducing these food-related GHG emissions, including eating seasonal produce and replacing dairy and red meat with plant-based products. In a national UK survey, we studied how many and which rules our participants gene…
A sampling model of social judgment
Studies of social judgments have demonstrated a number of diverse phenomena that were so far difficult to explain within a single theoretical framework. Prominent examples are false consensus and false uniqueness, as well as self-enhancement and self-depreciation. Here we show that these seemingly complex phenomena can be a product of an interplay between basic cognitive processes and the structure of social and task environments. We propose and …

Do children profit from looking beyond looks? From similarity-based to cue abstraction processes in multiple-cue judgment
The authors investigated the ability of 9- to 11-year-olds and of adults to use similarity-based and rule-based processes as a function of task characteristics in a task that can be considered either a categorization task or a multiple-cue judgment task, depending on the nature of the criterion (binary vs. continuous). Both children and adults relied on similarity-based processes in the categorization task. However, adults relied on cue abstracti…
Knowledge, attitudes and practice about malaria in rural Tigray, Ethiopia
OBJECTIVE: To assess the knowledge, attitude and practice (KAP) regarding malaria and their determinants in a rural population of northern Ethiopia. METHODS: The study was conducted in the district of Samre Saharti, Tigray, northern Ethiopia. A structured questionnaire collecting socio-demographic and malaria-related KAP information was administered to the mothers from a representative sample of households. RESULTS: A total of 1652 questionnaires…
Individuals and dyads in a multiple-cue judgment task
Brunswikian and Thurstonian Origins of Bias in Probability Assessment
Uppsala University, SwedenABSTRACTIn this paper the Brunswikian framework provided by the theory of ProbabilisticMental Models (PMM), and other theoretical stances inspired by probabilisticfunctionalism, is combined with the Thurstonian notion of a stochastic com-ponent of judgment. We review data from 25 tasks with representative selection ofitems collected in our laboratory. Over/underconfidence is close to zero in mostdomains, but there is a m…
Brunswikian and Thurstonian Origins of Bias in Probability Assessment
In this paper the Brunswikian framework provided by the theory of Probabilistic Mental Models (PMM), and other theoretical stances inspired by probabilistic functionalism, is combined with the Thurstonian notion of a stochastic component of judgment. We review data from 25 tasks with representative selection of items collected in our laboratory. Over/underconfidence is close to zero in most domains, but there is a moderate hard–easy effect across…
