  • Helping People in Times of Need Cultivates Empathy Over Time

    Open AccessDiego Guevara Beltrán, Jessica D Ayers et al.ARTICLESocial Psychological and…2026

    Why is lower social class often associated with greater empathy? We test whether less wealthy people experience more challenges, thereby motivating them to help others as a means of securing future social support, and, in turn, cultivating empathy over recurrent experiences. Study 1 ( N = 513) showed that wealth was negatively correlated with empathy through fewer challenges and less helping. Study 2 ( N = 915) replicated this effect while reveal…

  • Food scarcity and disease concern reduce interdependence when people eat together

    Food sharing is central to the human experience, serving biological and sociocultural functions. Historically, food sharing has allowed people to manage food shortages, creating positive interdependence among those who pool calories and other sources of risk. However, sharing food may lead to negative outcomes when food is scarce, or when there is a threat of disease. We found that sharing food (compared with sharing pencils) led to reduced coope…

  • Identities as predictors of vaccine hesitancy during the Covid‐19 pandemic

    Open AccessSamantha L Heiman, Edward R Hirt et al.ARTICLEJournal of Social Issues2023Cited by: 1References: 27

    Vaccine hesitancy is variable across individuals and contexts. Theoretical work suggests that group membership should differentially affect attitudes and behavior related to COVID‐19 vaccines, as individuals draw on their identities and experiences relevant to their social groups to deal with uncertainty concerning the vaccines. The present work uses longitudinal survey data to explore how identity predicted vaccination attitudes in the U.S. befo…

  • Agricultural decision making and climate uncertainty in developing countries

    Open AccessKurt B Waldman, Peter M Todd et al.ARTICLEEnvironmental Research Letters2020

    In situations of uncertainty, people often make decisions with heuristic shortcuts or decision rules, rather than using computational or logical methods such as optimizing their behavior based on specific goals. The high level of uncertainty and complexity involved in adapting to climate change suggests that heuristics would be commonly used in this context rather than more structured decision methods. Through a systematic review of 137 articles,…

    Social scientists have a longstanding theoretical interest in the relationship between individual behavior and social dynamics. A growing body of work demonstrates that, when human behavior is interdependent—that is, what one person does depends on the past, present, or anticipated future actions of others—there is not a simple or linear relationship between the choices of individuals and their collective consequences. Outside of the academy, pol…

    Open AccessEinav Hart, Judith Avrahami et al.ARTICLEJournal of Behavioral Decision…2015Cited by: 2References: 4

    Many competitions, such as political campaigns, innovative endeavors, sports, or courting rituals, require investment of nonrefundable resources: One contestant wins the prize for the invested amount, whereas all others lose their investments without receiving compensation. Frequently, contests are asymmetric, because of differing resources or prize valuations. Does asymmetry discourage the weaker contestants from investing? Do stronger contestan…

  • Modeling reproductive decisions with simple heuristics

    Open AccessPeter M Todd, Peter Todd et al.ARTICLEDemographic Research2013Cited by: 3References: 29

    Many of the reproductive decisions that humans make happen without much planning or forethought, arising instead through the use of simple choice rules or heuristics that involve relatively little information and processing. Nonetheless, these heuristic-gu

  • Mechanisms of ecological rationality

    Peter M Todd, Gerd GigerenzerCHAPTEROxford handbook of evolutionary…2012

    This article describes some of the simple heuristics that the human mind has evolved to use in particular circumstances, and the pressures on decision making that may have shaped the contents of the mind's adaptive toolbox. It begins by considering the notion of bounded rationality — the assumption that human cognition is constrained by limits of some sort — and just which types of bounds have been most important in cognitive evolution. It then l…

  • Cognitive Search

    Peter M Todd, Thomas T Hills et al.BOOKCognitive search2012

    Over a century ago, William James proposed that people search through memory much as they rummage through a house looking for lost keys. We scour our environments for territory, food, mates, and information. We search for items in visual scenes, for historical facts, and for the best deals on Internet sites; we search for new friends to add to our social networks, and for solutions to novel problems. What we find is always governed by how we sear…

  • Ecological RationalityIntelligence in the World

    Peter M Todd, Gerd GigerenzerBOOKEcological rationality2012

    "'More information is always better, and full information is best. More computation is always better, and optimization is best.' More-is-better ideals such as these have long shaped our vision of rationality. Yet humans and other animals typically rely on simple heuristics to solve adaptive problems, focusing on one or a few important cues and ignoring the rest, and shortcutting computation rather than striving for as much as possible. In this bo…

  • Can There Ever Be Too Many Options? A Meta-Analytic Review of Choice Overload

    Benjamin Scheibehenne, Rainer Greifeneder et al.ARTICLEJournal of Consumer Research2010

    The choice overload hypothesis states that an increase in the number of options to choose from may lead to adverse consequences such as a decrease in the motivation to choose or the satisfaction with the finally chosen option. A number of studies found strong instances of choice overload in the lab and in the field, but others found no such effects or found that more choices may instead facilitate choice and increase satisfaction. In a meta-analy…
