CONTINUOUS OPINIONS AND DISCRETE ACTIONS IN OPINION DYNAMICS PROBLEMS
TLDR
A model where agents show discrete behavior regarding their actions, but have continuous opinions that are updated by interacting with other agents, and its consequences are discussed. Expand

Probability biases as Bayesian inference
In this article, I will show how several observed biases in human probabilistic reasoning can be partially explained as good heuristics for making inferences in an environment where probabilitiesExpand

Bayesian updating rules in continuous opinion dynamics models
Here, I investigate the use of Bayesian updating rules applied to modeling how social agents change their minds in the case of continuous opinion models. Given another agent statement about theExpand

Adaptive Probability Theory: Human Biases as an Adaptation
Humans make mistakes in our decision-making and probability judgments. While the heuristics used for decision-making have been explained as adaptations that are both efficient and fast, the reasonsExpand

An opinion dynamics model for the diffusion of innovations
We study the dynamics of the adoption of new products by agents with continuous opinions and discrete actions (CODA). The model is such that the refusal in adopting a new idea or product isExpand

Change and Aging Senescence as an Adaptation
Understanding why we age is a long-lived open problem in evolutionary biology. Aging is prejudicial to the individual, and evolutionary forces should prevent it, but many species show signs ofExpand

TLDR
A model combining continuous opinions and observed discrete actions (CODA) capable of addressing the important issue of measuring how extreme opinions might be. Expand

Programmed Life Span in the Context of Evolvability
Population turnover is necessary for progressive evolution. In the context of a niche with fixed carrying capacity, aging contributes to the rate of population turnover. Theoretically, a populationExpand

Trust in the CODA model: Opinion Dynamics and the reliability of other agents
TLDR
A model for the joint evolution of opinions and how much the agents trust each other is presented, using the framework of the Continuous Opinions and Discrete Actions (CODA) model. Expand
