I summarise some aspects of the relation between quantum mechanics and the macroscopic world in the context of the multiverse or Everett theory. I do so with particular reference to the results of the theory of decoherence, the notions of reduction and emergence, and agents' decisions.

Living in cities has numerous comparative advantages than living in the countryside or in small villages and towns, most notably better access to education, services and jobs. However, it is also associated with a roughly twofold increase in some mental disorders rate incidence compared with living in rural areas. Economic assessments reported a forecasted loss of more than 19 trillion dollars in global GDP between 2011 and 2030 and of around 7 trillion for the year 2030 alone when measured by (...) the human capital method. If we exclude self-selection processes and make the hypothesis to be able to level down the mental illness rate incidence in urban areas to these of the rural by better urban-societal planning, around € 1.2 trillion could be saved yearly worldwide. Even a reduction of only 20% in urban mental illness rate would save around 250 billion dollars yearly. (shrink)

The aims of this study were twofold, to: examine the behavior displayed by participants who expected to be nominated for donor roles in dictator games wherein initial endowments of players are determined by lottery and investigate the conduct of donors who were confident in their good fortune in relation to their power as they redistributed the rewards they had gained. Results from a dictator game in which a donor is accorded the absolute power to redistribute initial income and a random (...) dictator game in which both a donor and a recipient declare their redistributive preferences and one of them is selected randomly by a computer were compared. Confident donors made more self-serving redistribution decisions than did unconfident donors in both games, but the difference was clearer in the dictator game. In relation to their preferences exhibited before being informed of their roles, confident donors decreased their redistribution amounts after discovering their roles; the decrements in the dictator game were conspicuously larger than those in the random dictator game. In short, confident donors were greedier than unconfident donors; the difference became more pronounced when their redistributive power was unconditional even though their confidence had no rational basis.

Dishonesty is prevalent and causes great damage to society. On an individual level, besides reaping rewards, it also carries a psychological cost for those who engage in it. This principle is used to make people more honest with behavioral interventions, one of them being the well-known ‘signature nudge’. Digital transition in society has however led to changes in the way people sign, which may affect the effectiveness of this nudge. In two experiments, the current study investigates the relationship between digital (...) signatures and honesty, building on previous research by examining novel signature types, the moderating role of personal characteristics, effect decay, and the predicting value of digital signature characteristics. Results show no effect of any signature intervention and no unilateral relation between digital signature characteristics and subsequent behavior. These findings contrast with earlier research and cast doubt on the use of signature interventions as a tool to prevent or predict dishonest behavior. (shrink)

The essay is a reflection on my conversations at the Humboldt Kreis connecting my understanding of entrepreneurship with the physics of the multiverse and the philosophy of free will.

This paper sketches a new version of the multiverse interpretation of quantum mechanics, the clustered-minds multiverse, that has been presented in detail elsewhere. It briefly shows why it grants us with free will and reflects upon the possibilty of singular-universe explanations of free will. It also critically comments upon S. Sarasvathy's 'choice matters,' one of the other contributions to this mini symposium.

Rational outcomes of a social system do not necessarily require its individual participants to be rational. In macro systems, aggregate properties distinct from the behavior of their micro level components can emerge through complex interactions. Caution in building social sciences on assumption of methodological individualism seems appropriate.

Among various computing models, it is difficult to find a model inspired from the human mind to improve the computational efficiency of the computer. In fact, the human mind becomes competent in responding for the inputs, resourcefully and mindfully acquiring knowledge and experience over continuous processing with the time. Further, as it is possible to find deeper explanation for the human mind in the Buddhism, the introduction of a computing model imitating the human mind based on Buddhist Theory of Mind (...) to enhance the computational efficiency, would be a great research challenge. According to the BTM, human mind is a continuous thought process which arise as per the conditions. Imitating this processing model in the human mind, a computing model called Six-state Continuous Processing model was introduced exploiting 24-causal relations in BTM. This paper discusses this profound Buddhist theoretical approach that was used in order to derive the Six-state continuous processing model. (shrink)

Heterogeneous beliefs and decision processes generate positive externalities for social and economic systems, analogous to biodiversity in biological systems. Although some aspects of biodiversity can lead to ecological and economic problems, biodiversity provides flows of beneficial ecological services and is widely regarded as a valuable natural resource and informational asset, whose value increases as we learn more and science progresses :700–706, 1985). Heterogeneous beliefs and decision processes similarly provide flows of beneficial economic services. Behavioral diversity should therefore be seen as (...) a natural resource and informational asset likely to improve human wellbeing in surprising ways in the future. Paternalistic policies motivated by the goal of “correcting” allegedly suboptimal beliefs and behavior that diverge from expert recommendations jeopardize behavioral diversity at a substantial cost to social welfare. The risk of encroaching on this beneficial behavioral heterogeneity with policies that aim to induce behavioral and belief monocultures should be included explicitly as costs when evaluating nudges and other paternalistic policies.

The procurement decision-making process for complex military product systems has significant implications for military end-users, suppliers, and exchequers. This study examines the usefulness of adopting a fast and frugal decision-making approach for the acquisition of military CoPS. Defence procurement environment is complex. On the one hand, there are uncertainties and severe resource constraints due to regularly changing threat perceptions, limited flow of information about new technologies, and the growing demand to reduce defence related expenses. On the other hand, several stakeholders (...) remain pre-occupied with the demand for ‘zero-error’ technologies. In such a setting, recurrent cost overruns and delays in supply are common in defence procurement programmes, across countries. Taking the illustrative examples of the missile system, fighter jet, and radar system acquisitions in India, we elucidate on ‘optimising’ versus ‘satisficing’ dynamics in the procurement decisions. The paper argues that a fast and frugal decision-making process by relying on judgement, experiential knowledge, and intuitive learning might make procurement processes, adaptively, more efficient. Such an approach would enable a ‘good enough’ technology to be inducted, and improved upon, through regular feedback from the actual environment. The study has implications for policy scholarships on innovation policy instruments under uncertainty. (shrink)

Huttenlocher et al. introduce the category adjustment model. Given that participants imperfectly remember stimuli, CAM holds that participants maximize accuracy by using information about the distribution of the targets to improve their judgments. CAM predicts that judgments will be a weighted average of the imperfect memory of the target and the mean of the distribution of targets. Huttenlocher et al. report on three experiments and conclude that CAM is “verified”. We attempt to replicate the conditions in Experiment 3 from Huttenlocher (...) et al.. We analyze judgment-level data rather than averaged data. We find evidence of a bias toward a set of recent targets rather than a bias toward the running mean. We do not find evidence of learning. The judgments in our dataset are not consistent with CAM. We discuss other defects in HHV—including dividing by zero. It seems that evidence for CAM is a statistical artifact that appears when researchers analyze data averaged across trials and do not consider a recency bias. (shrink)

Military service in general and combat service in particular can be physically and psychologically stressful. Previous studies have focused on risk propensity and risky behavior among soldiers. Yet knowledge is still lacking regarding the impact of type of army service on soldiers’ risk perceptions. The current study examines how type of army service and negative incidental emotions affect risk perceptions. Results of a survey conducted among 153 combat and non-combat Israeli soldiers indicate that respondents serving in combat units on average (...) have more pessimistic risk perceptions than non-combat soldiers. Yet no significant differences emerged between combat and non-combat respondents with respect to their levels of negative incidental emotions. Regression analyses suggest that higher levels of negative incidental emotions are correlated with pessimistic risk perceptions among all respondents, while higher levels of risk attitude are correlated with pessimistic risk perceptions among combat soldiers but not among non-combat soldiers.

In distributive bargaining, bargainers may have an impulse to bluff and thereby risk an impasse. The current paper does not explain bargaining impasses. For our purposes, it suffices to recognize that bargaining impasses may occur without assuming irrationality. The design problem is to ensure that impasses are avoided as often as possible. One possible solution is to allow for the formation of an agreement by “conduct”. The ‘agreement by conduct’ outcome as a commercial norm may coordinate bargainers’ expectations so as (...) to enable them to perform the same contract, even if they made written demands above ½. The idea that the “deal-is-on” philosophy as expressed in the “agreement-by-conduct” rule affects and promotes economic exchange is probed in the context of a modified Divide-the-Dollar game.

In fantasy sports, the goal is to gain as many points as possible. To get there, users have to choose players with the optimal price-to-performance ratio. However, finding these optimal players requires a great amount of time and effort, in which the users might not be willing to invest. Instead, they can use heuristic strategies. This paper investigates one such strategy for choosing squads based on the assumption that athletes starting for the favourite team of the match would bring users (...) more points—in line with the representativeness heuristic. The data come from the Czech fantasy league according to the Premier League in the season 2015–16. The econometric model examines the percentage of squads a player was chosen into. The Ordinary Least Squares method used here uses control variables indicating performance, price, Czech nationality, and the game position of the athletes. The results show that users choose their squads primarily based on players’ past performances, but also take the favourite team into account. By applying the latter heuristic users aim to simplify the process decision-making but they overestimate the impact of belonging to a favourite team. (shrink)

Metalogic is an open-ended cognitive, formal methodology pertaining to semantics and information processing. The language that mathematizes metalogic is known as metalanguage and deals with metafunctions purely by extension on patterns. A metalogical process involves an effective enrichment in knowledge as logical statements, and, since human cognition is an inherently logic–based representation of knowledge, a metalogical process will always be aimed at developing the scope of cognition by exploring possible cognitive implications reflected on successive levels of abstraction. Indeed, it is (...) basically impracticable to maintain logic–and–metalogic without paying heed to cognitive theorizing. For it is cognitively irrelevant whether possible conclusions are deduced from some premises before the premises are determined to be true or whether the premises themselves are determined to be true first and, then, the conclusions are deduced from them. In this paper we consider the term metalogic as inherently embodied under the framework referred to as cognitive science and mathematics. We propose a metalogical interpretation of Arrow’s impossibility theorem and, to that end, choice theory is understood as a mental course of action dealing with logic and metalogic issues, in which a possible mathematical approach to model a mental course of action is adopted as a systematic operating method. Nevertheless, if we look closely at the core of Arrow’s impossibility theorem in terms of metalogic, a second fundamental contribution to this framework is represented by the Nash equilibrium. As a result of the foregoing, therefore, we prove the metalogical equivalence between Arrow’s impossibility theorem and the existence of the Nash equilibrium. More specifically, Arrow’s requirements correspond to the Nash equilibrium for finite mixed strategies with no symmetry conditions. To demonstrate this proof, we first verify that Arrow’s set and Nash’s set are isomorphic to each other, both sets being under stated conditions of non–symmetry. Then, the proof is completed by virtue of category theory. Indeed, the two sets are categories that correspond biuniquely to one another and, thus, it is possible to define a covariant functor that preserves their mutual structures. According to this, we show the proof–dedicated metalanguage as a precursor to a special equivalence theorem. (shrink)

The evolution from pre-human primates to modern Homo sapiens is a complex one involving many domains, ranging from the material to the social to the cognitive, both at the individual and the community levels. This article focuses on a critical qualitative transition that took place during this evolution involving both the social and the cognitive domains. For the social domain, the transition is from the face-to-face forms of social interaction and organization that characterize the non-human primates that reached, with Pan, (...) a hiatus due to the centripetal effects that highly individualized behavior has on a social system. The transition is to the relation-based forms of social organization that evolved in the hominins ancestral to Homo sapiens and are universal in human societies today. For the cognitive domain, this transition involves going from behavior responding mainly to phenomenal level sensory inputs to behavior formed in accordance with the concept of a relation, initially abstracted from behavior patterns, then extending the concept of a relation beyond abstraction from behavior patterns to the concept of a relation generated recursively through constructing the relation of a relation. This extension made possible the construction of systems of relations; initially genealogical systems of relations constructed culturally using the logic of recursion, and subsequently, the symbolic, computational systems of kin term relations referred to by anthropologists as kinship terminologies. The latter are “constructed realities” in the sense this term is used by cultural anthropologists. It follows that the evolution of relation-based systems of social interaction is not adequately accounted for through population model evolutionary accounts such as the Dual Inheritance Theory of human evolution since “constructed realities” constitute collectively and publicly shared cultural knowledge rather than the individually and privately possessed knowledge that is assumed in the population model framework for human evolution.

A problem is a difference between what a person has and wants. A solution is anything that reduces the difference. These two simple definitions form the foundation of an ecological perspective on the often-complex, reciprocal relationships among people, their environments and their behaviours—a perspective that mixes causal ideas from psychology with consequential ideas from economics. The present article offers a brief introduction to this perspective and suggests how it might be instantiated by naturalistic observations and content analyses of narratives.
