Summary: This study conducted a large-scale comparison of 58 prominent models of risky choice, revealing that crowds of risky choice models perform better than individual models and provide a performance bound for assessing the historical accumulation of knowledge in the field. The results suggest that each model captures unique aspects of the decision process, and existing models offer complementary rather than competing accounts of behavior.

Summary: This research aims to detect the effects of closing and expanding paradox links in transportation and find effective measures to avoid Braess Paradox. The results show that higher capacity worsens Braess Paradox for monotonic links, even if the link capacity is increased infinitely. However, for non-monotonic links, adjusting the link capacity can avoid Braess Paradox. Expanding road infrastructure does not necessarily lead to a significant improvement in travel efficiency.

Summary: Through simulations, it is shown that belief in universalism leads to quicker convergence and higher total payoffs in coordination problems, while relativism has its own advantages such as maintaining diversity in certain cases.

Summary: Research suggests that using politically balanced groups of laypeople to identify misinformation is a feasible approach. Factors such as cognitive reflection, political knowledge, and party preference are related to agreement with fact-checkers among the general public.

Summary: This paper investigates Braess Paradox under the bi-objective user equilibrium, introducing the definition and occurrence conditions of the paradox. Analytical properties of the bi-objective user equilibrium solutions and the conditions for the occurrence of Braess Paradox are explored on a classical Braess network. The study proves that the occurrence conditions of Braess Paradox are dependent upon link performance parameters and travel demand.

Summary: Crowd-sourcing of information is popular in sports, but crowd-sourced transfer fees may be biased as predictors of true market fees. This affects their usefulness as proxies for unknown salary in academic research and their impact on negotiations between clubs and players.

Summary: Bacteria release and sense autoinducers to engage in quorum sensing, which is not only a means to estimate population density, but also a way to collectively sense the environment. A computational model shows that this functionality arises from individuals improving their estimation accuracy by pooling imperfect estimates, similar to the concept of 'wisdom of the crowds' in decision theory. This model reconciles the dependence of quorum sensing on both population density and the environment and explains the regulation of private goods production.

Summary: The wisdom of crowds refers to the phenomenon where the average opinion of a group closely aligns with the true answer. This requires group diversity of opinions and a small collective error. Social influence and individual conviction play a role in shaping opinions within the group, with social influence sometimes improving and sometimes deteriorating the outcome.

Summary: This article examines the issues with experts' point predictions of continuous outcomes and proposes a technique for updating means. It discusses how to improve the accuracy of means based on experts' predictions of multiple related outcomes, and demonstrates the technique on several real-world datasets.
