Toward a Philosophy of Blockchain: A Symposium: Introduction

This article introduces the symposium “Toward a Philosophy of Blockchain,” which provides a philosophical contemplation of blockchain technology, the digital ledger software underlying cryptocurrencies such as bitcoin, for the secure transfer of money, assets, and information via the Internet without needing a third‐party intermediary. The symposium offers philosophical scholarship on a new topic, blockchain technology, from a variety of perspectives. The philosophical themes discussed include mathematical models of reality, signification, and the sociopolitical institutions that structure human life and interaction. The symposium also investigates the metaphilosophical theme of how to create a philosophy of anything, specifically a new topic such as blockchain technology. Repeated themes are identified, in all areas of philosophical inquiry (ontology, epistemology, and axiology), and conceptual resources are elaborated to contribute to a philosophical understanding of blockchain technology. Thus, philosophy as a metaphilosophical approach is shown to be able to provide an understanding of the conceptual, theoretical, and foundational dimensions of novelty and emergence in the world, with a particular focus on blockchain technology.     

Thieves of thankfulness: Traits that inhibit gratitude

If gratitude is important to well-being, it is important to understand the factors that might inhibit gratitude. The purpose of this study was to investigate four putative inhibitors of gratitude: narcissism, cynicism, materialism/envy, and indebtedness. We used a prospective design where participants were administered measures related to the putative inhibitors along with trait and state gratitude, 2 months apart. After controlling for initial levels of gratitude, Time 1 narcissism, cynicism, and materialism/envy were negatively associated with Time 2 state gratitude. Evidence also supported the theory that narcissism and cynicism may interact in a vicious cycle over time. We conclude that narcissism, cynicism, and materialism inhibit state gratitude, and narcissism and cynicism may be the foundational ‘thieves of thankfulness.’     

Effects of Gender on Costly Punishment

Women are often believed to be more cooperative and less egoistic than men. In the present study, we examined whether people punish women for failing to live up to these benevolent gender stereotypes. Participants played a prisoner's dilemma game with female and male partners who either cooperated or defected. Participants were offered a costly punishment option. They could spend money to decrease the payment of their partners. In Experiment 1, participants spent more money to punish the defection of female in comparison to male partners, but this effect of partner gender on punishment was indirect rather than direct: Participants were more likely to cooperate with female partners than with male partners, which gave them more opportunity for moralistic punishment. In Experiments 2 and 3, we examined the effects of the participants' own gender on cooperation and punishment of female and male partners. Female participants cooperated more with female partners than with male partners while male participants treated female and male partners equally. We conclude that the effect of facial gender on punishment are indirect rather than direct. The results also showed that women, in contrast to men, tended to make decisions that can be considered more social and less rational from an economic point of view, consistent with social‐role theory and evolutionary accounts.

Antecedents of trust in the sharing economy: A systematic review

Users and potential users of the sharing economy need to place a considerable amount of trust in both the person and the platform with which they are dealing. The consequences of transaction partners’ opportunism may be severe, for example damage to goods or endangered personal safety. Trust is, therefore, a key factor in overcoming uncertainty and mitigating risk. However, there is no thorough overview of how trust is developed in this context. To understand how the trust of users in the sharing economy is influenced, we performed a systematic literature review. After screening, 45 articles were included in a qualitative synthesis in which the results were grouped according to a well‐established trust typology. The results show various antecedents of trust in the sharing economy (e.g. reputation, trust in the platform, and interaction experience) related to multiple entities (i.e. seller, buyer, platform, interpersonal, and transaction). Trust in this economy is often reduced to the use of reputation systems alone. However, our study suggests that trust is much more complex than that and extends beyond reputation. Furthermore, our review clearly shows that research on trust in the sharing economy is still scarce and thus more research is needed to understand how trust is established in this context. Our review is the first that brings together antecedents of trust in online peer‐to‐peer transactions and integrates these findings within an existing framework. Additionally, the study suggests directions for future research in order to advance the understanding of trust in the sharing economy.     

The Risk-Based View of Trust: A Conceptual Framework

Trust and risk have often been linked in the literature, but their relationship is far from clear. Trust has been used in three different ways — namely, as a perception (subjective trust), as various personal and situational factors that lead to subjective trust (trust antecedents), and as the actions resulting from subjective trust (behavioral trust). We explain how risk is related to these three conceptions of trust. First, we argue that subjective trust and perceived risk are in fact mirror images of each other. Second, we show how behavioral trust can be viewed as risk taking, so that the causal relationship between subjective trust and behavioral trust is similar to that of perceived risk and risk taking. And third, we discuss the role of personal characteristics (such as risk propensity and trust propensity) in the risk–trust relationship. We also develop a number of propositions based on our risk-based view of trust.     

Antecedents Of Trust: Establishing A Boundary Condition For The Relation Between Propensity To Trust And Intention To Trust

Two studies were conducted to examine the antecedents of intention to trust proposed by Mayer, Davis, and Schoorman [1995, Academy of Management Review, 20(3), 709–734]. In their model, intention to trust is influenced by the perceived characteristics of the trustee and the predisposition of the trustor. We found that perceived ability, benevolence, and integrity of the trustee predicted an individuals intention to trust. Propensity to trust, that is, an individuals disposition to trust, correlated with intention to trust when information about trustworthiness was ambiguous, but did not correlate with intention to trust when information about trustworthiness was clear. The notion of strong and weak situations is used to argue that situational strength is a boundary condition of the relation between propensity to trust and intention to trust.     

The impact of conflict of interest on trust in science

Conflicts of interest have an erosive effect on trust in science, damaging first the attitude of the public toward scientists and their research, but also weakening the trusting interdependence of scientists. Disclosure is recognized as the key tool for management of conflicts, but rules with sanctions must be improved, new techniques for avoidance of financial conflicts by alternative funding of evaluative research must be sought, and there must be new thinking about institutional conflicts of interest. Our profession is education, and both the public and research professionals of all ages would benefit from greater understanding of how science should and does work. An earlier version of this paper was presented at an International Conference on “Conflict of Interest and its Significance in Science and Medicine” held in Warsaw, Poland on 5–6 April, 2002.     

Preference for human or algorithmic forecasting advice does not predict if and how it is used

Past research has found that people treat advice differently depending on its source. In many cases, people seem to prefer human advice to algorithms, but in others, there is a reversal, and people seem to prefer algorithmic advice. Across two studies, we examine the persuasiveness of, and judges' preferences for, advice from different sources when forecasting geopolitical events. We find that judges report domain-specific preferences, preferring human advice in the domain of politics and algorithmic advice in the domain of economics. In Study 2, participants report a preference for hybrid advice, that combines human and algorithmic sources, to either one on it's own regardless of domain. More importantly, we find that these preferences did not affect persuasiveness of advice from these different sources, regardless of domain. Judges were primarily sensitive to quantitative features pertaining to the similarity between their initial beliefs and the advice they were offered, such as the distance between them and the relative advisor confidence, when deciding whether to revise their initial beliefs in light of advice, rather than the source that generated the advice.
