Urges now, interests later: On the factors and dynamics of epistemic curiosity

Abstract:

More information today is becoming more accessible to more people at an ever-growing rate. How does epistemic curiosity operate in this expanding informational landscape? We test a novel theory which postulates that experienced curiosity is a function of two psychological factors: Interest, which is cognitive, “cool” and relatively stable in time, and Urge that is “hot” and quick to rise and decay. These factors determine one's experienced curiosity at any given point in time. Interestingly, these temporal dynamics may lead to time-dependent changes in epistemic choices. In a series of forced-choice experiments (n = 702), participants chose between receiving answers to either high-Urge or high-Interest questions. Consistent with predictions derived from our theory, we found a present-bias in preference for Urge. Our theory explains why, in stark contrast to individual interest and with the potential to derail public discourse, a competition for our attention inherently incentivizes the use of inciting and sensational information. We present and test a theory-based behavioral nudge that partially ameliorates these effects.

Abstract:

An especially critical task is to raise awareness of the effects of war on children, in general, and with reference to specific children whose circumstances might enhance their vulnerability. Starting points, from which we begin our discussion, are the abduction and separation of 3-year-old identical twins during the Hamas attacks on the South of Israel, on October 7, 2023. Emphasis is given to these twins’ circumstances and to all children’s heightened vulnerability to the detrimental effects of war-related trauma, including mental health issues such as anxiety, depression, and post-traumatic stress disorder. Specific attention is given to the profound bond between identical twins and the devastating consequences of separation on their immediate and long-term emotional well-being. Drawing on research findings surrounding children at war and on historical evidence for the effects of twin separation on individuals exposed to war, our commentary underscores the urgent need for awareness and condemnation of the direct targeting of children. We advocate the preservation of family ties as essential for fostering children’s resilience and emotional support. We also call upon professional organizations and the international community to prioritize the reunification of children with their families as a moral imperative in safeguarding the well-being and future of innocent children exposed to terrorism and conflict in war-torn regions.

Abstract:

In this Article, we offer a new design for our patent system with a view

to optimize its functioning. As multiple patent scholars have recognized, the

root cause of the ills of our patent system is the high rate of low-quality

patents. Extant patent law employs a binary screening process, under which

inventions either qualify for protection or fail. Thereafter, all qualifying

inventions are entitled to the same level of protection irrespective of the

degree of their novelty, utility and nonobviousness. As we establish

throughout this Article, patent law’s failure to distinguish among inventions

based on their quality greatly undermines the patent system’s principal

objective of optimally incentivizing and adequately rewarding innovative

progress. Society, at least in principle, ends up paying the same price for

all qualifying inventions, regardless of their level of innovation and

improvement upon the prior art.

Individual differences in prioritization for consciousness and the conscious detection of changes

Abstract:

A recent discovery documented robust and reliable individual differences in how quickly people become aware of non-conscious visual stimuli (Sklar, Goldstein, et al., 2021). Given the seemingly large role that conscious experiences play in our lives, this trait is likely to be associated with later cognitive, emotional, and motivational processes. Here we examine the possible implications of this trait to perceptual conscious experiences. In two experiments we demonstrate that the speed of prioritization to awareness is correlated with the ability to notice changes in a change blindness paradigm. The first experiment (N = 97) found a correlation between prioritization speed and multiple parameters of change blindness performance. The second, preregistered, replication experiment (N = 99), further demonstrated that variability in other perceptual-decision making tasks cannot account for this correlation. The results of both experiments suggest that prioritization speed is tightly related with conscious experiences in other situations.

Human-induced pheromone pollution leads to changes in alternative mating tactics of moths

Abstract:

Environmental changes driven by anthropogenic activities often disrupt animal communication and mating behavior. Consequently, these changes may force animals to adopt alternative mating tactics and strategies to find a mate. The mating disruption technique is an environmentally friendly tactic often used to control the pink-bollworm moth population in cotton fields. Though mating disruption is eco-friendly, it represents a Human-Induced Rapid Environmental Change for the targeted moths. Mating disruption involves spreading a synthetic version of the species-specific sex pheromone in the field, creating a pheromone-polluted environment, making it difficult for male moths to locate females and thereby reducing mating rates. We hypothesized that the intense sexual selection and environmental changes affecting communication would lead moths to increase their use of alternative mating strategies. An observed alternative mating behavior in male pink bollworm moths is disturbing mating pairs to displace the male and mate with the female. We compared this behavior between two populations and found that males long exposed to mating disruption disturbed mating pairs more frequently than those never exposed to it. In addition, males with a prolonged history of exposure to mating disruption showed reduced choosiness of females and increased their mating rate with small females of lower reproductive potential. The success rate of the observed couple disturbance was low. Nonetheless, this strategy, alongside other strategies, may contribute to the males’ reproductive success when facing the additional challenge of locating females due to the pheromone-polluted environment.

Diversification of social complexity following a major evolutionary transition in bees

Abstract:

How social complexity evolved remains a long-standing enigma. In most animal groups, social complexity is typically classified into a few discrete classes. This approach is oversimplified and constrains our inference of social evolution to a narrow trajectory consisting of transitions between classes. Such categorical classifications also limit quantitative studies on the molecular and environmental drivers of social complexity. The recent accumulation of relevant quantitative data has set the stage to overcome these limitations. Here, we propose a data-driven, high-dimensional approach for studying the full diversity of social phenotypes. We curated and analyzed a comprehensive dataset encompassing 17 social traits across 80 species and studied the evolution of social complexity in bees. We found that honey bees, stingless bees, and bumble bees underwent a major evolutionary transition ∼80 mya, inconsistent with the stepwise progression of the social ladder conceptual framework. This major evolutionary transition was followed by a phase of substantial phenotypic diversification of social complexity. Other bee lineages display a continuum of social complexity, ranging from solitary to simple societies, but do not reach the levels of social complexity seen in honey bees, stingless bees, and bumble bees. Bee evolution, therefore, provides a remarkable demonstration of a macroevolutionary process in which a major transition removed biological constraints and opened novel evolutionary opportunities, driving the exploration of the landscape of social phenotypes. Our approach can be extended to incorporate additional data types and readily applied to illuminate the evolution of social complexity in other animal groups.

International Journal of Clinical and Health Psychology, 25(1). Retrieved from https://doi.org/10.1016/j.ijchp.2025.100548

Abstract:

Poor sleep is pervasive in modern society. Poor sleep is associated with major physical and mental health consequences, as well as with impaired cognitive function. Less is known about the relationship between sleep and emotional and interpersonal behavior. In this work, we investigate whether poor sleep impairs empathy, an important building block of human interaction and prosocial behavior. We aimed to capture the effects of poor sleep on the various aspects of empathy: trait and state, affect and cognition.

Study 1 (n = 155) assessed daily habitual sleep over several days, and global sleep quality in the past month. Participants who reported worse sleep quality exhibited lower empathic caring and perspective-taking traits. Study 2 (n = 347) induced a one-night disruption of sleep continuity to test a causal relationship between sleep and empathy. Participants in the sleep disrupted condition had to briefly wake up five times over the night, whereas the sleep-rested controls slept normally. In the next morning, participants’ empathy and prosocial intentions were assessed. Participants in the sleep disruption condition exhibited lower empathic sensitivity and less prosocial decision-making than sleep-rested controls.

The main contribution of this work is in providing a robust demonstration of the multi-faceted detrimental effects of poor sleep on trait and state empathy. Our findings demonstrate that poor sleep causally impairs empathic response to the suffering of others. These findings highlight the need for greater public attention to adequate sleep, which may impact empathy on a societal level.

Profound individual differences in contextualized emotion perception

Abstract:

Emotion perception is a fundamental aspect of our lives because others’ emotions may provide important information about their reactions, attitudes, intentions, and behavior. Following the seminal work of Ekman, much of the research on emotion perception has focused on facial expressions. Recent evidence suggests, however, that facial expressions may be more ambiguous than previously assumed and that context also plays an important role in deciphering the emotional states of others. Here, we adopt a novel approach, breaking down the means and documenting a robust trait in emotion perception. In six experiments with 671 participants, we find evidence for striking individual differences in emotion perception, with different people presenting profound differences in weighting the face versus the extrafacial context. Importantly, these differences are stable over time, stimuli, and paradigms. Our data show that individuals are interpreting identical emotional displays as communicating different emotions. Implications of these robust differences are discussed.

Abstract:

Innovations, such as symbolic artifacts, are a product of cognitive abilities but also of cultural context. Factors that may determine the emergence and retention of an innovation include the population's pre-existing cultural repertoire, exposure to relevant ways of thinking, and the invention's utility. Thus, we suggest that the production of symbolic artifacts is not guaranteed even in cognitively advanced societies.

Financial market exposure increases generalized trust

Abstract:

How can we build trust, especially in polarized societies? We propose that exposure to broad financial markets—where individuals place their assets in the hands of large groups of unfamiliar agents who nonetheless have the incentive and ability to promote their interests—can contribute to generalized trust. In a randomized controlled trial, we encourage Israelis to hold or trade stocks for up to seven weeks. We find that participation in financial markets increases the probability of expressing generalized trust by about 6 percentage points, equivalent to a quarter of the control group mean. The effects seem to be driven by political partisans along the left–right spectrum in Israel, and are robust to negative price changes. Thus, trust is not only a cause but can also be an effect of participation in financial markets.

Reclaiming the Public

Abstract:

Reclaiming the Public defines and defends the intrinsic value of “the public” that resides in our public institutions and the officials that run them. The book argues that public institutions do not simply act for us but instead speak and act in our name; i.e., they represent us. Representation requires that decisions made by public institutions or officials are consistent with the perspectives of citizens. If the decisions satisfy this requirement, these decisions are attributable to citizens, and citizens can be held responsible for them. This theory of political authority accounts for major features of our legal system, such as the non-instrumental grounds for the separation of law-making powers, the non-instrumental value of constitutions, the limits of privatization, the nature and value of public property, and the impermissibility of using artificial intelligence in setting certain policies and making certain decisions.

Abstract:

Maximizing the revenue from selling two or more goods has been shown to require the use of nonmonotonic mechanisms, where a higher-valuation buyer may pay less than a lower-valuation one. Here we show that the restriction to monotonic mechanisms may not just lower the revenue, but may in fact yield only a negligible fraction of the maximal revenue; more precisely, the revenue from monotonic mechanisms is no more than k times the simple revenue obtainable by selling the goods separately, or bundled (where k is the number of goods), whereas the maximal revenue may be arbitrarily larger. We then study the class of monotonic mechanisms and its subclass of allocation-monotonic mechanisms, and obtain useful characterizations and revenue bounds.

The Ethics of Memory

Avishai, M. . (2004). The Ethics of Memory.
The Ethics of Memory

Abstract:

Much of the intense current interest in collective memory concerns the politics of memory. In a book that asks, "Is there an ethics of memory?" Avishai Margalit addresses a separate, perhaps more pressing, set of concerns. The idea he pursues is that the past, connecting people to each other, makes possible the kinds of "thick" relations we can call truly ethical. Thick relations, he argues, are those that we have with family and friends, lovers and neighbors, our tribe and our nation--and they are all dependent on shared memories. But we also have "thin" relations with total strangers, people with whom we have nothing in common except our common humanity. A central idea of the ethics of memory is that when radical evil attacks our shared humanity, we ought as human beings to remember the victims. Margalit's work offers a philosophy for our time, when, in the wake of overwhelming atrocities, memory can seem more crippling than liberating, a force more for revenge than for reconciliation. Morally powerful, deeply learned, and elegantly written, The Ethics of Memory draws on the resources of millennia of Western philosophy and religion to provide us with healing ideas that will engage all of us who care about the nature of our relations to others.

The Elements of Computing Systems

Abstract:

In the early days of computer science, the interactions of hardware, software, compilers, and operating system were simple enough to allow students to see an overall picture of how computers worked. With the increasing complexity of computer technology and the resulting specialization of knowledge, such clarity is often lost. Unlike other texts that cover only one aspect of the field, The Elements of Computing Systems gives students an integrated and rigorous picture of applied computer science, as its comes to play in the construction of a simple yet powerful computer system.Indeed, the best way to understand how computers work is to build one from scratch, and this textbook leads students through twelve chapters and projects that gradually build a basic hardware platform and a modern software hierarchy from the ground up. In the process, the students gain hands-on knowledge of hardware architecture, operating systems, programming languages, compilers, data structures, algorithms, and software engineering. Using this constructive approach, the book exposes a significant body of computer science knowledge and demonstrates how theoretical and applied techniques taught in other courses fit into the overall picture.Designed to support one- or two-semester courses, the book is based on an abstraction-implementation paradigm; each chapter presents a key hardware or software abstraction, a proposed implementation that makes it concrete, and an actual project. The emerging computer system can be built by following the chapters, although this is only one option, since the projects are self-contained and can be done or skipped in any order. All the computer science knowledge necessary for completing the projects is embedded in the book, the only pre-requisite being a programming experience.The book's web site provides all tools and materials necessary to build all the hardware and software systems described in the text, including two hundred test programs for the twelve projects. The projects and systems can be modified to meet various teaching needs, and all the supplied software is open-source.

The New Unconscious

Abstract:

Over the past two decades, a new picture of the cognitive unconscious has emerged from a variety of disciplines that are broadly part of cognitive science. According to this picture, unconscious processes seem to be capable of doing many things that were thought to require intention, deliberation, and conscious awareness. Moreover, they accomplish these things without the conflict and drama of the psychoanalytic unconscious. These processes range from complex information processing, through goal pursuit and emotions, to cognitive control and self-regulation. This collection of 20 original chapters by leading researchers examines the cognitive unconscious from social, cognitive, and neuroscientific viewpoints, presenting some of the most important developments at the heart of this new picture of the unconscious. The volume, the first book in the new Social Cognition and Social Neuroscience series, will be an important resource on the cognitive unconscious for researchers in cognitive psychology and neuroscience.

The Economic Theory of Annuities

Sheshinski, E. . (2007). The Economic Theory of Annuities. Princeton University Press.
The Economic Theory of Annuities

Abstract:

Annuities are financial products that guarantee the holder a fixed return so long as the holder remains alive, thereby providing insurance against lifetime uncertainty. The terms of these contracts depend on the information available to insurance firms. Unlike age and gender, information about individual survival probabilities cannot be readily ascertained. This asymmetric information causes market inefficiencies, such as adverse selection. Groundbreaking in its scope, The Economic Theory of Annuities offers readers a theoretical analysis of the functioning of private annuity markets. Starting with a general analysis of survival functions, stochastic dominance, and characterization of changes in longevity, Eytan Sheshinski derives the demand for annuities using a model of individuals who jointly choose their lifetime consumption and retirement age. The relation between life insurance and annuities that have a bequest option is examined and "annuity options" are proposed as a response to the lack of secondary markets. This book also investigates the macroeconomic policy implications of annuities and changes in longevity on aggregate savings. Sheshinski utilizes statistical population theory to shed light on the debate of whether the surge in savings and growth in Asia and other countries can be attributed to higher longevity of the population and whether this surge is durable. This book shows how understanding annuities becomes essential as governments that grapple with insolvency of public social security systems place greater emphasis on individual savings accounts.

This book systematically presents the main solutions of cooperative games: the core, bargaining set, kernel, nucleolus, and the Shapley value of TU games as well as the core, the Shapley value, and the ordinal bargaining set of NTU games. The authors devote a separate chapter to each solution, wherein they study its properties in full detail. In addition, important variants are defined or even intensively analyzed.

Cold Intimacies

Cold Intimacies

Abstract:

It is commonly assumed that capitalism has created an a-emotional world dominated by bureaucratic rationality; that economic behavior conflicts with intimate, authentic relationships; that the public and private spheres are irremediably opposed to each other; and that true love is opposed to calculation and self-interest. Eva Illouz rejects these conventional ideas and argues that the culture of capitalism has fostered an intensely emotional culture in the workplace, in the family, and in our own relationship to ourselves. She argues that economic relations have become deeply emotional, while close, intimate relationships have become increasingly defined by economic and political models of bargaining, exchange, and equity. This dual process by which emotional and economic relationships come to define and shape each other is called emotional capitalism. Illouz finds evidence of this process of emotional capitalism in various social sites: self-help literature, women's magazines, talk shows, support groups, and the Internet dating sites. How did this happen? What are the social consequences of the current preoccupation with emotions? How did the public sphere become saturated with the exposure of private life? Why does suffering occupy a central place in contemporary identity? How has emotional capitalism transformed our romantic choices and experiences? Building on and revising the intellectual legacy of critical theory, this book addresses these questions and offers a new interpretation of the reasons why the public and the private, the economic and the emotional spheres have become inextricably intertwined.

Game Theoretic Analysis of Voting in Committees

Citation:

Peleg, B. . (2008). Game Theoretic Analysis of Voting in Committees. Cambridge University Press.
Game Theoretic Analysis of Voting in Committees

Abstract:

This book is a theoretical and completely rigorous analysis of voting in committees that provides mathematical proof of the existence of democratic voting systems, which are immune to the manipulation of preferences of coalitions of voters. The author begins by determining the power distribution among voters that is induced by a voting rule, giving particular consideration to choice by plurality voting and Borda's rule. He then constructs, for all possible committees, well-behaved representative voting procedures which are not distorted by strategic voting, giving complete solutions for certain important classes of committees. The solution to the problem of mass elections is fully characterised.

Strategic Social Choice: Stable Representations of Constitutions

Strategic Social Choice: Stable Representations of Constitutions

Abstract:

This monograph studies representations of effectivity functions by game forms that are at least Nash consistent, which means that they have a Nash equilibrium for any profile of preferences. In the second part the focus is on social choice functions that admit a strong Nash equilibrium resulting in the sincere outcome. A central interpretation of an effectivity function is that it models a constitution.

Pathological Altruism

Pathological Altruism

Abstract:

The benefits of altruism and empathy are obvious. These qualities are so highly regarded and embedded in both secular and religious societies that it seems almost heretical to suggest they can cause harm. Like most good things, however, altruism can be distorted or taken to an unhealthy extreme. Pathological Altruism presents a number of new, thought-provoking theses that explore a range of hurtful effects of altruism and empathy. Pathologies of empathy, for example, may trigger depression as well as the burnout seen in healthcare professionals. The selflessness of patients with eating abnormalities forms an important aspect of those disorders. Hyperempathy - an excess of concern for what others think and how they feel - helps explain popular but poorly defined concepts such as codependency. In fact, pathological altruism, in the form of an unhealthy focus on others to the detriment of one's own needs, may underpin some personality disorders. Pathologies of altruism and empathy not only underlie health issues, but also a disparate slew of humankind's most troubled features, including genocide, suicide bombing, self-righteous political partisanship, and ineffective philanthropic and social programs that ultimately worsen the situations they are meant to aid. Pathological Altruism is a groundbreaking new book - the first to explore the negative aspects of altruism and empathy, seemingly uniformly positive traits. The contributing authors provide a scientific, social, and cultural foundation for the subject of pathological altruism, creating a new field of inquiry. Each author's approach points to one disturbing truth: what we value so much, the altruistic "good" side of human nature, can also have a dark side that we ignore at our peril.

מדוע האהבה כואבת

תקציר:

מעטים האנשים שלא חוו את הייסורים הכרוכים במערכות יחסים אינטימיות. לייסורים אלה צורות רבות: אנחנו אוהבים גבר או אישה שלא מוכנים להתחייב לנו, לבנו נשבר כאשר אהובנו או אהובתנו עוזבים אותנו, אנחנו שקועים בחיפושים סיזיפיים באינטרנט, חוזרים גלמודים מברים, ממסיבות או מפגישות עיוורות, משתעממים במערכת יחסים הרחוקה כל כך מציפיותינו. בספרה החדש והנועז, מדוע האהבה כואבת, מנסה פרופסור אווה אילוז, מבכירי הסוציולוגים בעולם, לבחון את החוויות האלה, הפרטיות לכאורה, באמצעות התבוננות ביקורתית בדרכים שבהן מיוצרת, נכתבת, משווקת ונחווית האהבה בימינו. לטענת אילוז, הפסיכואנליזה והפסיכולוגיה הפופולרית הפליאו לשכנע אותנו שיחידים נושאים באחריות לאומללות חייהם הרומנטיים והארוטיים. ואילו מטרתו של הספר הזה היא לשנות את זווית הניתוח של הבעיה במערכות יחסים בימינו ולהסביר כי לא ילדות לקויה היא הבעיה אלא הכוחות המוסדיים שמעצבים את האופן שבו אנחנו אוהבים. אווה אילוז היא פרופסור לסוציולוגיה באוניברסיטה העברית בירושלים ונשיאת האקדמיה לאמנות ועיצוב בצלאל. עבודותיה בתחום הסוציולוגיה של הרגשות זכו להכרה רחבה. מדוע האהבה כואבת פורסם באנגלית, בצרפתית ובגרמנית, עורר הדים רבים, זכה לשבחים ואף היה לרב-מכר. בעברית ראו אור עד כה ארבעה מספריה הקודמים, ביניהם אינטימיות קרה – עלייתו של הקפיטליזם הרגשי וגאולת הנפש המודרנית – פסיכולוגיה, רגשות ועזרה עצמית. כמו כן מפרסמת אילוז מסות בענייני תרבות וחברה במוסף "הארץ".
