Popularity of reinforcement-based and belief-based learning models: an evolutionary approach

In an evolutionary model, players from a given population meet randomly in pairs each instant to play a coordination game. At each instant, the learning model used is determined via some replicator dynamics that respects payoff fitness. We allow for two such models: a belief-based best-response model that uses a costly predictor, and a costless reinforcement-based one. This generates dynamics over the choice of learning models and the consequent choices of endogenous variables. We report conditions under which the long run outcomes are efficient (or inefficient) and they support the exclusive use of either of the models (or their co-existence).

Seven heavens? The character and importance of afterlife belief among contemporary Australians

This article draws on in-depth qualitative interviews with 52 people to examine the meaning and character of afterlife belief among contemporary Australians. It explores the varieties of afterlife belief and considers the impact such beliefs have, particularly in relation to death and dying. The analysis reveals that afterlife belief is varied, individualistic and mainly arrived at with little to no reference to orthodox religious teaching. People variously believe in heaven, reincarnation, life on another planet or something more abstract. Those who follow faithfully a religious tradition are largely ignorant of detailed theological doctrines about life after death and like other kinds of believers, exercise their own authority and judgment over matters of belief.

Echoes of the past: the influence of spiritualism on contemporary belief

At once controversial and intriguing, Spiritualism has spread from the United States to become a global movement. Bringing together perspectives from within the movement and without, this unique collection treats readers to insights about Spiritualism's history, belief, and practice.Based on the belief that the dead can communicate with the living through mediums, Spiritualism touches concepts as timelessly fascinating as human mortality and the continuing existence of the soul beyond bodily death. This comprehensive work will help readers parse the mysteries of this uniquely American religion through three thematically organized volumes: Spiritualism in the U.S. and Globally, Evidence and Beliefs, and Cultural and Social Issues. Drawing on fields as diverse as psychology, sociology, religious studies, anthropology, history, ethnic and gender studies, literature, and art, this broad-based collection frames Spiritualism through the views of a team of international scholars.Among the many things that separate Spiritualism from mainstream religions is the involvement of women in central leadership roles. Such cultural and political elements of the movement are one aspect of this study. Of equal interest to believers and skeptics alike will be the work of scholars who have devoted themselves to examining the claim that communication through mediums proves the existence of life after death.

Better the devil you know than a world you don't? Intolerance of uncertainty and worldview explanations for belief in conspiracy theories

Conspiracy Theory (CT) endorsers believe in an omnipresent, malevolent, and highly coordinated group that wields secret influence for personal gain, and credit this group with the responsibility for many noteworthy events. Two explanations for the emergence of CTs are that they result from social marginalisation and a lack of agency, or that they are due to a need-to-explain-the-unexplained. Furthermore, representativeness heuristics may form reasoning biases that make such beliefs more likely. Two related studies (N = 107; N = 120) examined the relationships between these social marginalisation, intolerance of uncertainty, heuristics and CT belief using a correlational design. Overall, intolerance of uncertainty did not link strongly to CT belief, but worldview variables did - particularly a sense of the world as (socially) threatening, non-random, and with no fixed morality. The use of both representative heuristics that were examined was heightened in those participants more likely to endorse CTs. These factors seem to contribute to the likelihood of whether the individual will endorse CTs generally, relating similarly to common CTs, CTs generally historically accepted as "true", and to the endorsement of fictional CTs that the individual would find novel. Implications are discussed.

One more time : not just (with) words, but feelings. commentary on 'beyond belief'

How can psychological description orient to an experiential understanding inclusive of and sensitive to situated ontological variability? To do so requires development of theory capable of engaging people in the living of their lives reconciling notions of personhood within the prospective nature of psychosocial action.This commentary considers Cromby's argument and its capacity to realise theory of this kind.

The Post-revision drift, analyst characteristics and investor attention

The aim of this dissertation is to provide a coherent explanation for the post-analyst recommendation drift. First, I find that the post-analyst recommendation drift is explained by the degree of attention paid by individual investors. Second I find that the extremeness and the credibility of information leads to changes in the degree of attention and a post-analyst recommendation drift. Finally, I find that the diffusion of private information contained in the analyst recommendation interacts with attention related biases leading to a post-recommendation drift.
