Personal profile

Shira's research focuses on reasoning, decision making, and rationality. A major theme in her research is the study of normativity in rationality and in human inference. This is a two-pronged approach, encompassing both conceptual analysis and experimental research. The conceptual strand of this work is a critique of normativist conceptions of rationality, i.e. the idea that rationality should be judged by normative benchmarks (Elqayam & Evans, 2011; Evans & Elqayam, 2011).

The critique argues that normativism has led psychology of reasoning and decision making to dubious inference from ‘is’ to ‘ought’, as well as to a host of research biases, and that a descriptivist research agenda would benefit psychology.

The empirical strand of this theme (Elqayam et al., 2015; 2017) examines the way that people infer normative conclusions from descriptive premises. Findings indicate that such inference is driven by the causal link between action and outcome and the psychological value of the outcome, but it can be suppressed when reasoners are presented with competing outcomes or competing normative values.

dc.title: Developing and testing an integrative model of work-family conflict in a Chinese context dc.contributor.author: Chen, Shujie; Cheng, M.; Elqayam, Shira; Scase, M. O. dc.description.abstract: Given that the field of work-family conflict is overwhelmingly Western-focused and that the process of work-family conflict might change under a different cultural background, the aim of the present study was to develop and test an integrated work-family conflict model that is applicable in China. Using a sample of 520 Chinese participants and structural equation modelling in R studio, the differences between the present study and previous Western findings were identified. The results revealed that family support was positively related to time spent on family responsibilities and negatively related to life satisfaction; only work-to-family conflict, but not family-to-work conflict, had three forms of unique antecedent (time-, strain-, behavioural-based); and more surprisingly, work-family conflict was positively related to life satisfaction in China. This study refined our understanding of work-family conflict and enriched our knowledge of how work-family conflict acted in China鈥檚 work-family interface, providing directions for future cross-cultural work-family conflict studies. dc.description: The file attached to this record is the author's final peer reviewed version.

dc.title: Conceptual Spaces and the Strength of Similarity-based Arguments dc.contributor.author: Douven, Igor; Elqayam, Shira; Gardenfors, Peter; Mirabile, Patricia dc.description.abstract: Central to the conceptual spaces framework is the thought that concepts can be studied mathematically, by geometrical and topological means. Various applications of the framework have already been subjected to empirical testing, mostly with excellent results, demonstrating the framework鈥檚 usefulness. So far untested is the suggestion that conceptual spaces may help explain certain inferences people are willing to make. The experiment reported in this paper focused on similarity-based arguments, testing the hypothesis that the strength of such arguments can be predicted from the structure of the conceptual space in which the items being reasoned about are represented. A secondary aim of the experiment concerned a recent inferentialist semantics for indicative conditionals, according to which the truth of a conditional requires the presence of a sufficiently strong inferential connection between its antecedent and consequent. To the extent that the strength of similarity-based inferences can be predicted from the geometry and topology of the relevant conceptual space, such spaces should help predict truth ratings of conditionals embodying a similarity-based inferential link. The results supported both hypotheses. dc.description: The file attached to this record is the author's final peer reviewed version.
dc.title: Inference strength predicts the probability of conditionals better than conditional probability does dc.contributor.author: Douven, Igor; Elqayam, Shira; Mirabile, Patricia dc.description.abstract: According to the philosophical theory of inferentialism and its psychological counterpart, Hypothetical Inferential Theory (HIT), the meaning of an indicative conditional centrally involves the strength of the inferential connection between its antecedent and its consequent. This paper states, for the first time, the implications of HIT for the probabilities of conditionals. We report two experiments comparing these implications with those of the suppositional account of conditionals, according to which the probability of a conditional equals the corresponding conditional probability. A total of 358 participants were presented with everyday conditionals across three different tasks: judging the probability of the conditionals; judging the corresponding conditional probabilities; and judging the strength of the inference from antecedent to consequent. In both experiments, we found inference strength to be a much stronger predictor of the probability of conditionals than conditional probability, thus supporting HIT. dc.description: The file attached to this record is the author's final peer reviewed version.

dc.title: Conditionals and Inferential Connections: Toward a New Semantics dc.contributor.author: Douven, Igor; Elqayam, Shira; Singmann, Henrik; van Wijnbergen-Huitink, Janneke dc.description.abstract: In previous published research (鈥淐onditionals and Inferential Connections: A Hypothetical Inferential Theory,鈥� Cognitive Psychology, 2018), we investigated experimentally what role the presence and strength of an inferential connection between a conditional鈥檚 antecedent and consequent plays in how people process that conditional. Our analysis showed the strength of that connection to be strongly predictive of whether participants evaluated the conditional as true, false, or neither true nor false. In this paper, we re-analyze the data from our previous research, now focusing on the semantics of conditionals rather than on how they are processed. Specifically, we use those data to compare the main extant semantics with each other and with inferentialism, a semantics according to which the truth of a conditional requires the presence of an inferential connection between the conditional鈥檚 component parts. dc.description: The file attached to this record is the author's final peer reviewed version.

dc.title: Structured decision-making drives guidelines panels鈥� recommendations 鈥榝or鈥� but not 鈥榓gainst鈥� health interventions dc.contributor.author: Djulbegovic, B.; Reljic, T.; Elqayam, Shira; Cuker, A.; Hozo, I.; Zhou, Q.; Li, S.-A.; Alexander, P.; Nieuwlaat, R.; Wiercioch, W.; Sch眉nemann, H.; Guyatt, G. dc.description.abstract: Background: The determinants of guideline panels鈥� recommendations remain uncertain. Objective: To investigate factors considered by members of 8 panels convened by the American Society of Hematology (ASH) to develop guidelines using GRADE system. Study Design and Setting: web-based survey of the participants in the ASH guidelines panels. Analysis: two level hierarchical, random-effect, multivariable regression analysis to explore the relation between GRADE and non-GRADE factors and strength of recommendations (SOR). Results: In the primary analysis, certainty in evidence [OR=1.83; (95CI% 1.45 to 2.31)], balance of benefits and harms [OR=1.49 (95CI% 1.30 to 1.69)] and variability in patients鈥� values and preferences [OR=1.47 (95CI% 1.15 to 1.88)] proved the strongest predictors of SOR. In a secondary analysis, certainty of evidence was associated with a strong recommendation [OR=3.60 (95% CI 2.16 to 6.00)] when panel members recommended 鈥渇or鈥� interventions but not when they made recommendations 鈥渁gainst鈥� [OR=0.98 (95%CI: 0.57 to 1.8)] consistent with 鈥測es鈥� bias. Agreement between individual members and the group in rating SOR varied (kappa ranged from -0.01 to 0.64). Conclusion: GRADE鈥檚 conceptual framework proved, in general, highly associated with SOR. Failure of certainty of evidence to be associated with SOR against an intervention, suggest the need for improvements in the process.
dc.title: How and why we reason from is to ought dc.contributor.author: Evans, J. St. B. T.; Elqayam, Shira dc.description.abstract: Originally identified by Hume, the validity of is-ought inference is much debated in the meta-ethics literature. Our work shows that inference from is to ought typically proceeds from contextualised, value-laden causal utility conditional, bridging into a deontic conclusion. Such conditional statements tell us what actions are needed to achieve or avoid consequences that are good or bad. Psychological research has established that people generally reason fluently and easily with utility conditionals. Our own research also has shown that people鈥檚 reasoning from is to ought (deontic introduction) is pragmatically sensitive and adapted to achieving the individual鈥檚 goals. But how do we acquire the necessary deontic rules? In this paper, we provide a rationale for this facility linked to Evans鈥檚 (2010) framework of dual mind rationality. People have an old mind (in evolutionary terms) which derives its rationality by repeating what has worked in the past, mostly by experiential learning. New mind rationality, in contrast, is evolutionarily recent, uniquely developed in humans, and draws on our ability to mentally simulate hypothetical events removed in time and place. We contend that the new mind achieves its goals by inducing and applying deontic rules and that a mechanism of deontic introduction evolved for this purpose. dc.description: The file attached to this record is the author's final peer reviewed version.

dc.title: Many faces of rationality: Implications of the great rationality debate for clinical decision-making dc.contributor.author: Djulbegovic, B.; Elqayam, Shira dc.description.abstract: Given that more than 30% of healthcare costs are wasted on inappropriate care, suboptimal care is increasingly connected to the quality of medical decisions. It has been argued that personal decisions are the leading cause of death, and 80% of healthcare expenditures result from physicians' decisions. Therefore, improving healthcare necessitates improving medical decisions, ie, making decisions (more) rational. Drawing on writings fromThe Great Rationality Debate from the fields of philosophy, economics, and psychology, we identify core ingredients of rationality commonly encountered across various theoretical models. Rationality is typically classified under umbrella of normative (addressing the question how people 鈥渟hould鈥� or 鈥渙ught to鈥� make their decisions) and descriptive theories of decision鈥� making (which portray how people actually make their decisions). Normative theories of rational thought of relevance to medicine include epistemic theories that direct practice of evidencebasedmedicine and expected utility theory, which provides the basis for widely used clinical decision analyses. Descriptive theories of rationality of direct relevance to medical decision鈥恗aking include bounded rationality, argumentative theory of reasoning, adaptive rationality, dual processing model of rationality, regret鈥恇ased rationality, pragmatic/substantive rationality, and meta鈥恟ationality. For the first time, we provide a review of wide range of theories and models of rationality. We showed that what is 鈥渞ational鈥� behaviour under one rationality theory may be irrational under the other theory. We also showed that context is of paramount importance to rationality and that no one model of rationality can possibly fit all contexts. We suggest that in context鈥恜oor situations, such as policy decision鈥恗aking, normative theories based on expected utility informed by best research evidence may provide the optimal approach to medical decision鈥恗aking, whereas in the context鈥恟ich circumstances other types of rationality, informed by human cognitive architecture and driven by intuition and emotions such as the aim to minimize regret, may provide better solution to the problem at hand. The choice of theory under which we operate is important as it determines both policy and our individual decision鈥恗aking. dc.description: open access article
dc.title: Rational decision-making in medicine: implications for overuse and underuse dc.contributor.author: Djulbegovic, B.; Elqayam, Shira; Dale, W. dc.description.abstract: In spite of substantial spending and resource utilization, today's health care remains characterized by poor outcomes, largely due to overuse (over-testing/treatment) or underuse (under-testing/treatment) of services. To a significant extent, this is a consequence of low-quality decision-making that appears to violate various rationality criteria. Such sub-optimal decision-making is considered a leading cause of death and is responsible for more than 80% of health expenses. In this paper, we address the issue of overuse or underuse of healthcare interventions from the perspective of rational choice theory. We show that what is considered rational under one decision theory may not be considered rational under a different theory. We posit that the questions and concerns regarding both underuse and overuse have to be addressed within a specific theoretical framework. The applicable rationality criterion, and thus the 鈥渁ppropriateness鈥� of health care delivery choices, depends on theory selection that is appropriate to specific clinical situations. We provide a number of illustrations showing how the choice of theoretical framework influences both our policy and individual decision-making. We also highlight the practical implications of our analysis for the current efforts to measure the quality of care and link such measurements to the financing of healthcare services. dc.description: open access article
dc.title: Conditionals and inferential connections: A hypothetical inferential theory dc.contributor.author: Douven, Igor; Elqayam, Shira; Singmann, Henrik; van Wijnbergen-Huitink, Janneke dc.description.abstract: Intuition suggests that for a conditional to be evaluated as true, there must be some kind of connection between its component clauses. In this paper, we formulate and test a new psychological theory to account for this intuition. We combined previous semantic and psychological theorizing to propose that the key to the intuition is a relevance-driven, satisficing-bounded inferential connection between antecedent and consequent. To test our theory, we created a novel experimental paradigm in which participants were presented with a soritical series of objects, notably colored patches (Experiments 1 and 4) and spheres (Experiment 2), or both (Experiment 3), and were asked to evaluate related conditionals embodying non-causal inferential connections (such as 鈥淚f patch number 5 is blue, then so is patch number 4鈥�). All four experiments displayed a unique response pattern, in which (largely determinate) responses were sensitive to parameters determining inference strength, as well as to consequent position in the series, in a way analogous to belief bias. Experiment 3 showed that this guaranteed relevance can be suppressed, with participants reverting to the defective conditional. Experiment 4 showed that this pattern can be partly explained by a measure of inference strength. 顏s pattern supports our theory鈥檚鈥減rinciple of relevant inference鈥� and 鈥減rinciple of bounded inference,鈥� highlighting the dual processing characteristics of the inferential connection. dc.description: The file attached to this record is the author's final peer reviewed version.
