    Artificial intelligence systems are increasingly demonstrating their capacity to make better predictions than human experts. Yet, recent studies suggest that professionals sometimes doubt the quality of these systems and overrule machine-based prescriptions. This paper explores the extent to which a decision maker (DM) supervising a machine to make high-stake decisions can properly assess whether the machine produces better recommendations. To that end, we study a set-up, in which a machine performs repeated decision tasks (e.g., whether to perform a biopsy) under the DM's supervision. Because stakes are high, the DM primarily focuses on making the best choice for the task at hand. Nonetheless, as the DM observes the correctness of the machine's prescriptions across tasks, she updates her belief about the machine. However, the DM observes the machine's correctness only if she ultimately decides to act on the task. Further, the DM sometimes overrides the machine depending on her belief, which affects learning. In this set-up, we characterize the evolution of the DM's belief and overruling decisions over time. We identify situations under which the DM hesitates forever whether the machine is better, i.e., she never fully ignores but regularly overrules it. Moreover, the DM sometimes wrongly believes with positive probability that the machine is better. We fully characterize the conditions under which these learning failures occur and explore how mistrusting the machine affects them. Our results highlight some fundamental limitations in determining whether machines make better decisions than experts and provide a novel explanation for human-machine complementarity.

    Whether one looks at revenue, public and private investment, or media coverage; men's sports consistently do better than women's sports. Many people argue that these differences are driven by absolute differences in the quality of athletes in men's and women's sports. We begin by noting that absolute differences in athletic skill often do not drive demand in sports. We then move on to our primary research question: Can people truly see differences in men and women athletes? To answer this question, we use videos of professional women’s and men’s soccer. In some videos the gender of the athletes was clear to see. In other videos, though, the gender of the athletes was blurred. We find that participants only rate men’s soccer videos higher when the gender of the players is visible. These findings reveal a bias in the evaluation of men’s and women’s soccer relevant for many other fields. Our results demonstrate that factors other than performance, e.g., social beliefs and stereotypes, have an important influence on how individuals evaluate women in sports

    The objective of this research was to analyze the relationship between leadership styles and executive functions of planning and decision-making, in chief officers of the Argentine Navy, who are working as students of the Command and General Staff course at the Naval War School. A survey was carried out where a sample of 21 chief officers of the Argentine Navy in the rank of Lieutenant Commander was analyzed, in a population of 153 qualified for command function, whose age range is between 37 and 46 years old, resulting in an average of 40.71 years and an average length of service in the force of 20.88 years, ranging between 18 and 24 years of service. This sample was made up of officers from three different ranks, naval (n = 9), naval aviators (n = 6) and marines (n = 6). The results obtained indicate the absence of correlation between the leadership styles that these officers demonstrated and the skills in the executive functions of decision-making and planning. Likewise, it was found that the values obtained from the tests carried out yielded results that allow to conclude that the chief officers of the Argentine Navy in the Lieutenant Commander hierarchy possess very high competencies in decision-making and planning, as well as oriented leadership profiles to transformational leadership. The conclusions is that these competencies are significant for the operational and tactical leadership of the means and personnel in the Argentine Navy.

    Artificial intelligence systems are increasingly demonstrating their capacity to make better predictions than human experts. Yet, recent studies suggest that professionals sometimes doubt the quality of these systems and overrule machine-based prescriptions. This paper explores the extent to which a decision maker (DM) supervising a machine to make high-stake decisions can properly assess whether the machine produces better recommendations. To that end, we study a set-up in which a machine performs repeated decision tasks (e.g., whether to perform a biopsy) under the DM's supervision. Because stakes are high, the DM primarily focuses on making the best choice for the task at hand. Nonetheless, as the DM observes the correctness of the machine's prescriptions across tasks, she updates her belief about the machine. However, the DM is subject to a so-called verification bias such that the DM verifies the machine's correctness and updates her belief accordingly only if she ultimately decides to act on the task. In this set-up, we characterize the evolution of the DM's belief and overruling decisions over time. We identify situations under which the DM hesitates forever whether the machine is better, i.e., she never fully ignores but regularly overrules it. Moreover, the DM sometimes wrongly believes with positive probability that the machine is better. We fully characterize the conditions under which these learning failures occur and explore how mistrusting the machine affects them. These findings provide a novel explanation for human-machine complementarity and suggest guidelines on the decision to fully adopt or reject a machine.

    We examine the risky choices of pairs of contestants in a popular radio game show in France. At one point during the COVID-19 pandemic the show, held in person, had to switch to an all-remote format. We find that such an exogenous change in social context affected risk-taking behavior. Remotely, pairs take far fewer risks when the stakes are high than in the flesh. This behavioral difference is consistent with prosocial behavior theories, which argue that the nature of social interactions influences risky choices. Our results suggest that working from home may reduce participation in profitable but risky team projects.

    This paper reports on a preregistered study aimed at testing for executive function differences across individuals who self-reported one of four distinct dietary patterns: No Diet, No Sugar, Vegetarian, and Mediterranean Diet patterns. The incentivized decision task involves Bayesian assessments where participants may use existing (base rate) as well as new information (sample draw evidence) in making probability assessments. Sample size, hypotheses, and analysis plans were all determined ex ante and registered on the Open Science Framework. Our hypotheses were aimed at testing whether adherence to a specialty diet improved decision making relative to those who reported following No Diet. Our data fail to support these hypotheses. In fact, we found some evidence that adherence to a No Sugar Diet predicted a reduced decision accuracy and was connected to an increased imbalance in how the participant weighted the two sources of information available. Our results suggest that decision making is nuanced among dietary groups, but that short-term incentivized decisions in an ecologically valid field setting are likely not improved solely by following a promoted diet such as the Mediterranean or Vegetarian diet.

    Evidence points to an increasing personalisation of political power by chief executives in recent years. It is often argued that such personalisation contributes to the current trend of autocratisation and the global decline of democracy. Yet our understanding hereof remains fractured, not least because there are a plethora of tacit understandings, definitions, and concepts vis-à-vis what political personalisation is. While potentially occurring in both autocracies and democracies, the scholarship is still too often siloed according to regime type. We thus develop a framework defining the phenomenon as a process in which the chief executive personalises power in policymaking and policy implementation by weakening the constraining capacities of relevant actors. The "personalisation of executive power" (PEXP) runs through three distinct mechanisms: personnel management, institutional engineering, and power arrogation. We illustrate the usefulness of our conceptual framework with four case studies during the COVID-19 pandemic: El Salvador, Ghana, South Korea, and Zimbabwe.

    ‘Routine action’, a form to take action, is widely accepted in the economic field, because of its resource saving effect which contributes to average cost degression. However, from an entropic point of view, each form of acting requires decision making in regard to consumption of resources and causes entropic effects. Therefore, any kind of mechanistic resource management has to be avoided, even for routine action, when well-balanced economic-entropic actions, as to call them sustainable, are the objective. The paper shows how entropic and economic advantages and disadvantages of routine action can be brought together in a ratio to measure its sustainability’s relevance.
