Purpose of review: What is the relationship between rationality and mental health? By considering the psychological literature on depressive realism and unrealistic optimism it was hypothesized that, in the context of judgments about the self, accurate cognitions are psychologically maladaptive and inaccurate cognitions are psychologically adaptive. Recent studies recommend being cautious in drawing any general conclusion about style of thinking and mental health. Recent findings: Recent investigations suggest that people with depressive symptoms are more accurate than controls in tasks involving (...) time perception and estimates of personal circumstances, but not in other tasks. Unrealistic optimism remains a robust phenomenon across a variety of tasks and domains, and researchers are starting to explore its neural bases. However, the challenge is to determine to what extent and in what way unrealistic optimism is beneficial. Summary: We should revisit the hypothesis that optimistic cognitions are psychologically adaptive, whereas realistic thinking is not. Realistic beliefs and expectations can be conducive to wellbeing and good functioning, and wildly optimistic cognitions have considerable psychological costs. (shrink)

Hunter-gatherer punishment involves costs and benefits to individuals and groups, but the costs do not necessarily fit with the assumptions made in models that consider punishment to be altruistic – which brings in the free-rider problem and the problem of second-order free-riders. In this commentary, I present foragers' capital punishment patterns ethnographically, in the interest of establishing whether such punishment is likely to be costly; and I suggest that in many cases abstentions from punishment that might be (...) taken as defections by free-riders are actually caused by social-structural considerations rather than being an effect of free-rider genes. This presentation of data supplements the ethnographic analysis provided by Guala. (shrink)

Introduction to a special issue of Consciousness and Cognition on the costs and benefits of imperfect cognitions.

The “reproductive suppression hypothesis” states that the strong desire of adolescent girls in our culture to control their weight may reflect the operation of an adaptive mechanism by which ancestral women controlled the timing of their sexual maturation and hence first reproduction, in response to cues about the probable success of reproduction in the current situation. We develop a model based on this hypothesis and explore its behavior and evolutionary and psychological implications across a range of parameter values. We use (...) the process of model development to identify assumptions implicit in the reproductive suppression hypothesis and variables that need to be measured in order to investigate it more fully. In addition, because costs were probably associated with weight control, an important part of this analysis is the specification of situations in which the benefits of adaptive adjustment of the maturation schedule could have outweighed the costs of achieving that adjustment by slowing adolescent weight gain.

In this paper I discuss the costs and benefits of confabulation, focusing on the type of confabulation people engage in when they offer explanations for their attitudes and choices. What makes confabulation costly? In the philosophical literature confabulation is thought to undermine claims to self-knowledge. I argue that when people confabulate they do not necessarily fail at mental-state self-attributions, but offer ill-grounded explanations which often lead to the adoption of other ill-grounded beliefs. What, if anything, makes confabulation beneficial? (...) As people are unaware of the information that would make their explanations accurate, they are not typically in a position to acknowledge their ignorance or provide better-grounded explanations for their attitudes and choices. In such cases, confabulating can have some advantages over offering no explanation because it makes a distinctive contribution to people’s sense of themselves as competent and largely coherent agents. This role of ill-grounded explanations could not be as easily played by better-grounded explanations should these be available. In the end, I speculate about the implications of this conclusion for attempting to eliminate or reduce confabulation. (shrink)

Few ethical issues create as much controversy as invasive experiments on animals. Some scientists claim they are essential for combating major human disease, or detecting human toxins. Others claim the contrary, backed by thousands of patients harmed by pharmaceuticals developed using animal tests. Some claim all experiments are conducted humanely, to high scientific standards. Yet, a wealth of studies have recently revealed that laboratory animals suffer significant stress, which may distort experimental results. -Where, then, does the truth lie? -How useful (...) are such experiments in advancing human healthcare? -How much do animals suffer as a result? -And do students really need to dissect or experiment on animals? -What are the effects on their attitudes towards them? Bioethicist and veterinarian Andrew Knight presents more than a decade of ground-breaking scientific research, analysis and experience to provide evidence-based answers to a key question: is animal experimentation ethically justifiable?

Although the standard theory and actual practice of cost-benefit analysis are seriously defective, the general idea of making social policy in accord with an aggregative, maximizing, consequentialist criterion is a sensible one. Therefore it is argued, against Bantz, that interpersonal utility comparisons can be meaningful, and, against both Bantz and MacLean, that quantitative overall assessments of expected value provide a presumptively rational basis for social choice. However, it does not follow that introducing cost-benefit tests into the political or legal process (...) would always be optimal: recognizing some quite stringent legal rights against involuntary exposure to pollution or risk may actually promote cost-beneficial results more reliably than cost-benefit tests employed in very imperfect circumstances.

Is it ethical to deceive the individuals who participate in psychological experiments for methodological reasons? We argue against an absolute ban on the use of deception in psychological research. The potential benefits of many psychological experiments involving deception consist in allowing individuals and society to gain morally significant self-knowledge that they could not otherwise gain. Research participants gain individual self-knowledge which can help them improve their autonomous decision-making. The community gains collective self-knowledge that, once shared, can play a role (...) in shaping education, informing policies and in general creating a more efficient and just society. (shrink)

Employee participation is essential to organizations’ corporate social responsibility (CSR)-related environmental initiatives (EIs). Employees’ attitudes to participating in pro-environmental behaviors are addressed in workplace literature drawing upon the theory of planned behavior. However, antecedents to employees’ attitude formation, including perceptions of the costs and benefits of participating in EIs, have not been adequately researched. Greater understanding of EI attitude formation can support efforts to foster EI participation. This study explores employees’ perceptions of EI costs and benefits (...) to employees personally, to their organization, and to society by applying goal framing theory. A sample of 120 survey participants described 150 initiatives and identified personal, organizational, and societal costs and benefits of the EIs. Cost and benefit categories are presented along with a taxonomy and themes. The findings of this study provide a reference point for researchers and managers in understanding how employees view EIs and how employees might be encouraged to participate. (shrink)

This paper addresses how to think about the permissibility of introducing deadweight costs on candidate recipients of goods in order to attain better outcomes. The paper introduces some distinctions between different kinds of value dimensions that should be taken into account when such judgements are made and draws from the literature on comparisons across different value dimensions in order to canvas what sort of situations one might arguably face when evaluating ordeals. In light of the distinctions drawn and the (...) possibilities canvassed, the paper proceeds to outline what circumstances indicate which of the possible situations one is in. (shrink)

Sex differences in aggressive behavior are probably adaptive but the costs and benefits of risky aggression to women and men may be different from those suggested in Campbell's target article. Moreover, sex differences are more likely to reflect differences in the costs of aggression to females and males rather than differences in its benefits.

The present study examined the costs and benefits of native language similarity for non-native vocabulary learning. Because learning a second language is difficult, many learners start with easy words that look like their native language to jumpstart their vocabulary. However, this approach may not be the most effective strategy in the long-term, compared to introducing difficult L2 vocabulary early on. We examined how L1 orthographic typicality affects pattern learning of novel vocabulary by teaching English monolinguals either Englishlike or (...) Non-Englishlike pseudowords that contained repeated orthographic patterns. We found that overall, the first words that individuals learned during initial acquisition influenced which words they acquired later. Specifically, learning a new word in one session made it easier to acquire an orthographically similar word in the next session. Similarity among non-native words interacted with native language similarity, so that words that looked more like English were easier to learn at first, but they were less effective at influencing later word learning. This demonstrates that although native language similarity has a beneficial effect early on, it may reduce learners' ability to benefit from non-native word patterns during continued acquisition. This surprising finding demonstrates that making learning easier may not be the most effective long-term strategy. Learning difficult vocabulary teaches the learner what makes non-native words unique, and this general wordform knowledge may be more valuable than the words themselves. We conclude that native language similarity modulates new vocabulary acquisition and that difficulties during learning are not always to be avoided, as additional effort early on can pay later dividends.

In this paper data from a Tanzanian horticultural population are used to assess whether mother’s kin network size predicts several measures of children’s health and well-being, and whether any kin effects are modified by household socioeconomic status. This hypothesis is further tested with a questionnaire on maternal attitudes towards kin. Results show small associations between measures of maternal kin network size and child mortality and children’s growth performance. Together these results suggest that kin positively influence child health, but the effects (...) are small and it is unlikely that the high prevalence of undernutrition observed in this setting is influenced by the availability of kin.

In their controversial 2016 paper in this journal, Brennan and Magness argue that fair pay for part-time, adjunct faculty would be unaffordable for most colleges and universities and would harm students as well as many adjunct faculty members. In this critique, I show that their cost estimates fail to take account of the potential benefits of fair pay for adjunct faculty and are based on implausible assumptions. I propose that pay per course for new adjunct faculty members should be (...) tied to pay per course for new full-time non-tenure track instructors or to pay per course for new assistant professors. That framework for adjunct faculty justice yields an aggregate cost range of $18.5–$27.9 billion, one-third to one-half lower than the range computed by Brennan and Magness. Its opportunity cost would not be borne by students since students and faculty are complements, not substitutes, in the educational process. Instead it could be financed by reducing spending on non-educational purposes. Current adjunct faculty members would be protected from job displacement in this justice framework. The real obstacle to achieving justice for adjunct faculty is the priorities of university administrators, not budget constraints or opportunity costs. (shrink)

Demographic diversity might often be present in a group without group members noticing it. What are the epistemic effects if they do? Several philosophers and social scientists have recently argued that when individuals detect demographic diversity in their group, this can result in epistemic benefits even if that diversity doesn’t involve cognitive differences. Here I critically discuss research advocating this proposal, introduce a distinction between two types of detection of demographic diversity, and apply this distinction to the theorizing on (...) diversity in science. Focusing on ‘invisible’ diversity, I argue that in one common kind of group in science, if group members have full insight into their group’s diversity, this is likely to create epistemic costs. These costs can be avoided and epistemic benefits gained if group members only partly detect their group’s diversity. There is thus an epistemic reason for context-dependent limitations on scientists’ insight into the diversity of their group. (shrink)

A teleological approach to deciding how we should act underlies the attempted extension of neo-classical economics to environmental issues, with its emphasis on comparative valuation in monetary terms. Such an extension fails because, in the environmental sphere, there are powerful reasons for denying commensurability of the relevant values. But this denial then tends to undercut any weighing of environmental goods. In response to this difficulty, the paper seeks to develop an account of the weighing of goods which would enable us (...) to recognise value as a human creation, while also grounding it in an ecological unity with the wider life of nature.

Chow's book provides a thorough analysis of the confusing array of issues surrounding conventional tests of statistical significance. This book should be required reading for behavioral and social scientists. Chow concludes that the null-hypothesis significance-testing procedure (NHSTP) plays a limited, but necessary, role in the experimental sciences. Another possibility is that – owing in part to its metaphorical underpinnings and convoluted logic – the NHSTP is declining in importance in those few sciences in which it ever played a role.

We often remember in the company of others. In particular, we routinely collaborate with friends, family, or colleagues to remember shared experiences. But surprisingly, in the experimental collaborative recall paradigm, collaborative groups remember less than their potential, an effect termed collaborative inhibition. Rajaram and Pereira-Pasarin (2010) argued that the effects of collaboration on recall are determined by “pre-collaborative” factors. We studied the role of 2 pre-collaborative factors—shared encoding and group relationship—in determining the costs and benefits of collaborative recall. (...) In Experiment 1, we compared groups of strangers who encoded alone versus together, before collaborating to recall. In Experiment 2, we compared groups of friends who encoded alone versus together, before collaborating to recall. We found that shared encoding abolished collaborative inhibition in both Experiments 1 and 2. But prior relationship did not influence collaborative inhibition over and above the effects of shared encoding. Regardless of encoding condition, collaborative group recall contained fewer intrusions than nominal group recall, and these benefits continued in subsequent individual recall. Our findings demonstrate that pre-collaborative factors—specifically shared encoding—have flow-on benefits for group and individual recall amount, but not recall accuracy. We discuss these findings in terms of self- and cross-cuing in collaborative recall. (shrink)

In “How to Collaborate,” Paul Thagard tries to explain why there is so much collaboration in science, and so little collaboration in philosophy, by giving an epistemic cost-benefit analysis. In this paper, I argue that an adequate explanation requires a more fully developed epistemic value theory than Thagard utilizes. In addition, I offer an alternative to Thagard’s explanation of the lack of collaboration in philosophy. He appeals to its lack of a tradition of collaboration and to the a priori nature (...) of much philosophical research. I claim that philosophers rarely collaborate simply because they can usually get the benefits without paying the costs of actually collaborating. (shrink)

A central point of debate over environmental policies concerns how future costs and benefits should be assessed. The most commonly used method for assessing the value of future costs and benefits is economic discounting. One often-cited justification for discounting is uncertainty. More specifically, it is risk aversion coupled with the expectation that future prospects are more risky. In this paper I argue that there are at least two reasons for disputing the use of risk aversion as (...) a justification for discounting when dealing with longterm decisions, one technical and one ethical. Firstly, I argue that technically, it implies an inconsistency between theory and practice. And secondly, I argue that discounting for uncertainty relies on a form of individualism which, while reasonable in standard microeconomic theory where an agent chooses how to spread her own consumption over her own lifetime, is inappropriate in the context of intergenerational social decisions.

This article presents two related challenges to the idea that, to ensure policy evaluation is comprehensive, all costs and benefits should be aggregated into a single, equity-weighted wellbeing metric. The first is to point out how, even allowing for equity-weighting, the use of a single metric limits the extent to which we can take distributional concerns into account. The second challenge starts from the observation that in this and many other ways, aggregating diverse effects into a single metric (...) of evaluation necessarily involves settling many moral questions that reasonable people disagree about. This raises serious questions as to what role such a method of policy evaluation can and should play in informing policy-making in liberal democracies. Ultimately, to ensure comprehensiveness of policy evaluation in a wider sense, namely, that all the diverse effects that reasonable people might think matter are kept score of, we need multiple metrics as inputs to public deliberation.

The puzzle of how altruism can evolve has been at the center of recent debates over Hamilton’s Rule, inclusive fitness, and kin-selection. In this paper, I use recent debates over altruism and Hamilton’s legacy as an example to illustrate a more general problem in evolutionary theory that has philosophical significance; I attempt to explain this significance and to draw a variety of conclusions about it. The problem is that specific behaviours and general concepts of organism agency and intentionality are defined (...) in terms of concepts of evolutionary “costs” and “benefits,” and these terms have determined the role that agency should play in evolutionary explanation. However, costs, benefits, and agency are not only or even best conceived through evolutionary effects in a biological context. The paper proceeds as follows: first, I explain how the issue of agency relates to the evolutionary puzzle of altruism. Next, I discuss how questions about agency have figured in recent debates over Hamilton’s legacy. In the final section, I argue that Denis Walsh’s “situated Darwinism,” which attempts to return the organism to central status in biological explanation, offers a more productive route for thinking about different forms of costs, benefits, and agency. Finally, I argue that the upshot of all this is that there may be many different, and equally valid, ways to express what organisms are doing and how they are behaving based on different currencies of cost and benefit—even if these may stand in some tension. I illustrate this through returning to the case of altruism and using examples to show that even in non-humans there can be many forms of altruism, even if they are not all biological altruism as defined in the conventional evolutionary terms.

The scale is the most famous emblem of the law, including intellectual property (IP). Because IP rights impose social costs on the public by limiting access to protected work, the law can be justified only to the extent that, on balance, it encourages enough creation and dissemination of new works to offset those costs. The scale is thus a potent rhetorical trope of fairness and objectivity, but also an instrument the law thinks with – one that is constantly (...) invoked to justify or to question the extent of available IP protection. The balancing act that underlies the legitimacy of IP is, however, literally impossible to perform. Because we are unable to measure the benefits that IP has for inventors or the costs it has for the public, the scale has nothing to weigh. It conveys a clear sense that IP law can be balanced, but in fact propagates only a visible simulacrum of balance – one that is as empty as it is powerful. (shrink)

Despite its theoretical importance, little is known about how semantic memory structure facilitates and constrains creative idea generation. We examine whether the semantic richness of a concept has both benefits and costs to creative idea generation. Specifically, we tested whether cue set size—an index of semantic richness reflecting the average number of elements associated with a given concept—impacts the quantity (fluency) and quality (originality) of responses generated during the Alternate Uses Task (AUT). Across four studies, we show that (...) low-association, sparse, AUT cues benefit originality at the cost of fluency compared to high-association, rich, AUT cues. Furthermore, we found an interaction with individual differences in fluid intelligence in the low-association AUT cues, suggesting that constraints of sparse semantic knowledge can be overcome with top-down intervention. Our findings indicate that semantic richness differentially impacts the quality and quantity of generated ideas, and that cognitive control processes can facilitate idea production when conceptual knowledge is limited.

Social grooming is an important element of social life in terrestrial primates, inducing the putative benefits of β-endorphin stimulation and group harmony and cohesion. Implicit in many analyses of grooming (e.g. biological markets) are the assumptions of costs and benefits to grooming behaviour. Here, in a review of literature, we investigate the proximate costs and benefits of grooming, as a potentially useful explanatory substrate to the well-documented ultimate (functional) explanations. We find that the hedonic (...) class='Hi'>benefits of grooming are well documented. However, we did not find convincing evidence for costs. If proximate costs do exist, they might consist of energetic, cognitive, opportunity costs, or some combination of all of these. Nonetheless, there remains the possibility that grooming costs are negligible, or even that the provision of allogrooming is rewarding in itself. We suggest empirical research to resolve this issue.
