According to Kanazawa (Psychol Rev 111:512–523, 2004), general intelligence, which he considers as a synonym of abstract thinking, evolved specifically to allow our ancestors to deal with evolutionary novel problems while conferring no advantage in solving evolutionary familiar ones. We present a study whereby the results contradict Kanazawa’s hypothesis by demonstrating that performance on an evolutionary novel problem (an abstract reasoning task) predicts performance on an evolutionary familiar problem (a social reasoning task).

Do moral appraisals shape judgments of intentionality? A traditional view is that individuals first evaluate whether an action has been carried out intentionally. Then they use this evaluation as input for their moral judgments. Recent studies, however, have shown that individuals’ moral appraisals can also influence their intentionality attributions. They attribute intentionality to the negative side effect of a given action, but not to the positive side effect of the same action. In three experiments, we show that this asymmetry is (...) a robust effect that critically depends on the agent’s beliefs. The asymmetry is reduced when agents are described as not knowing that their action can bring about side effects, and is eliminated when they are deemed to hold a false belief about the consequences of their actions. These results suggest that both evaluative and epistemic considerations are used in intentionality attribution. (shrink)

This commentary questions Elqayam & Evans' (E&E's) claims that thinking tasks are doomed to have multiple normative readings and that only applied research allows normative evaluations. In fact, some tasks have just one undisputed normative reading, and not only pathological gamblers but also normal individuals sometimes need normative guidance. To conclude, normative evaluations are inevitable in the investigation of human thinking.

We have found that moral considerations interact with belief ascription in determining intentionality judgment. We attribute this finding to a differential availability of plausible counterfactual alternatives that undo the negative side-effect of an action. We conclude that Knobe's thesis does not account for processes by which counterfactuals are generated and how these processes affect moral evaluations.

I discuss an aspect of individual differences which has not been considered adequately in the target article, despite its potential role in the rationality debate. Besides having different intellectual abilities, different individuals may produce different erroneous responses to the same problem. In deductive reasoning, different response patterns contradict deterministic views of deductive inferences. In decision-making, variations in nonoptimal choice may explain successful collective actions.

People can reason about the preferences of other agents, and predict their behavior based on these preferences. Surprisingly, the psychology of reasoning has long neglected this fact, and focused instead on disinterested inferences, of which preferences are neither an input nor an output. This exclusive focus is untenable, though, as there is mounting evidence that reasoners take into account the preferences of others, at the expense of logic when logic and preferences point to different conclusions. This article summarizes the most (...) recent account of how reasoners predict the behavior and attitude of other agents based on conditional rules describing actions and their consequences, and reports new experimental data about which assumptions reasoners retract when their predictions based on preferences turn out to be false.

An individual obtains an unfair benefit and faces the dilemma of either hiding it (to avoid being excluded from future interactions) or disclosing it (to avoid being discovered as a deceiver). In line with the target article, we expect that this dilemma will be solved by a fixed individual strategy rather than a case-by-case rational calculation.

Diagnoses of rationality often arise from the experimental investigation of human reasoning. We suggest that such diagnoses can be disputed on various grounds and provide a classification. We then argue that much fruitful research done with classical experimental paradigms was triggered by normative concerns and yet fostered insight in properly psychological terms. Our examples include the selection task, the conjunction fallacy, and so-called pseudodiagnosticity. We conclude that normative considerations retain a constructive role in the psychology of reasoning, contrary to recent (...) complaints in the literature. (shrink)

This article outlines a theory of naive probability. According to the theory, individuals who are unfamiliar with the probability calculus can infer the probabilities of events in an extensional way: They construct mental models of what is true in the various possibilities. Each model represents an equiprobable alternative unless individuals have beliefs to the contrary, in which case some models will have higher probabilities than others. The probability of an event depends on the proportion of models in which it occurs. (...) The theory predicts several phenomena of reasoning about absolute probabilities, including typical biases. It correctly predicts certain cognitive illusions in inferences about relative probabilities. It accommodates reasoning based on numerical premises, and it explains how naive reasoners can infer posterior probabilities without relying on Bayes's theorem. Finally, it dispels some common misconceptions of probabilistic reasoning. (shrink)

Many fields of study have shown that group discussion generally improves reasoning performance for a wide range of tasks. This article shows that most of the population, including specialists, does not expect group discussion to be as beneficial as it is. Six studies asked participants to solve a standard reasoning problem—the Wason selection task—and to estimate the performance of individuals working alone and in groups. We tested samples of U.S., Indian, and Japanese participants, European managers, and psychologists of reasoning. Every (...) sample underestimated the improvement yielded by group discussion. They did so even after they had been explained the correct answer, or after they had had to solve the problem in groups. These mistaken intuitions could prevent individuals from making the best of institutions that rely on group discussion, from collaborative learning and work teams to deliberative assemblies.

Four studies show that observers and readers imagine different alternatives to reality. When participants read a story about a protagonist who chose the more difficult of two tasks and failed, their counterfactual thoughts focused on the easier, unchosen task. But when they observed the performance of an individual who chose and failed the more difficult task, participants' counterfactual thoughts focused on alternative ways to solve the chosen task, as did the thoughts of individuals who acted out the event. We conclude (...) that these role effects may occur because participants' attention is engaged when they experience or observe an event more than when they read about it. (shrink)

This paper replies to Politzer’s (2007) criticisms of the mental model theory of conditionals. It argues that the theory provides a correct account of negation of conditionals, that it does not provide a truth-functional account of their meaning, though it predicts that certain interpretations of conditionals yield acceptable versions of the ‘paradoxes’ of material implication, and that it postulates three main strategies for estimating the probabilities of conditionals.

The idea of social injustice is pivotal to much contemporary moral and political philosophy. Starting from a comprehensive and engaging account of the idea of social injustice, this book covers a whole range of issues, including distributive justice, exploitation, torture, moral motivations, democratic theory, voting behavior, and market socialism.

Can the Marxist tradition still provide new resources for thinking the specificity of historical time? This volume proposes to transform our understanding of Marxism by reconnecting with the 'subterranean currents' of plural temporalities that have traversed its development. From Rousseau and Sieyès to Marx, from Bloch to Althusser, from Gramsci to Pasolini and Postcolonialism, the chapters in this volume seek both to valorise neglected resources from Marxism's contradictory history, and also to read against the grain its orthodox and heterodox currents. (...) Privileging not the single time of historical development, but the plural temporalities that intertwine in and constitute any given historical conjuncture, and arguing against merely subjectivist theories of temporal multiplicity, this volume studies the articulation of the real, plural temporalities of mass political action. Comprehending their dynamics is a necessary precondition for a renewed politics of emancipation.Contributors include: Luca Basso, Stefano Bracaletti, Mauro Farnesi Camellone, Fabio Frosini, Augusto Illuminati, Nicola Marcucci, Vittorio Morfino, Luca Pinzolo, Peter D.

Background The 2020-2021 coronavirus (Covid-19) pandemic is just the latest epidemic event that requires us to rethink and change our understanding of health. Health should no longer be conceived only in relation to human beings, but in unitary terms, as a dimension that connects humans, animals, plants, and the environment (holistic view, One Health). In general, alterations occurring in this articulated chain of life trigger a domino effect. Methodology In this paper, we review the One Health paradigm in the light (...) of the Covid-19 pandemic and distinguish two approaches within it that might be dubbed the Prudent one and the Radical one. Each approach is structured in three levels – epistemological, medical, and ethical. Results In this way, we show how we humans can better address the pandemic today and how, in the future, we can treat the whole living system better, by renouncing our anthropocentric perspective on health. Conclusion We hold that the Prudent approach can be very helpful, and we discuss the medical and ethical issues related to it. We also consider the Radical view and the epistemological turn it requires compared to the Prudent one. (shrink)

Nel cammino della filosofia il realismo ha spesso costituito l’asse fondamentale della ricerca. Esso è in grado di rinnovare il pensiero, oggi, quando la filosofia moderna si è chiusa, sostituita dalla presente povertà postmetafisica e dal disfattismo della ragione. Il volume mette alla prova la forza del realismo, intrecciando riflessione teoretica e riflessione storiografica, e dando voce ad autori come Tommaso d’Aquino, Hegel, Schelling, Gentile, Maritain, Bontadini, Severino, Putnam.

The study of ethical behavior in the field of leadership began in the 1990s when Murphy et al. (1992) responded to a call by Randall and Gibson (1990) to develop more rigorous methodologies in empi...

A new class of visuomotor neuron has been recently discovered in the monkey’s premotor cortex: mirror neurons. These neurons respond both when a particular action is performed by the recorded monkey and when the same action, performed by another individual, is observed. Mirror neurons appear to form a cortical system matching observation and execution of goal-related motor actions. Experimental evidence suggests that a similar matching system also exists in humans. What might be the functional role of this matching system? One (...) possible function is to enable an organism to detect certain mental states of observed conspecifics. This function might be part of, or a precursor to, a more general mind-reading ability. Two different accounts of mind-reading have been suggested. According to “theory theory‘, mental states are represented as inferred posits of a naive theory. According to “simulation theory‘, other people’s mental states are represented by adopting their perspective: by tracking or matching their states with resonant states of one’s own. The activity of mirror neurons, and the fact that observers undergo motor facilitation in the same muscular groups as those utilized by target agents, are findings that accord well with simulation theory but would not be predicted by theory theory.

Who was Max Weber? How did he live? What were his dreams, desires and designs? What relationship existed between his life, his illness and his work? Why are his studies of capitalism and China still so important today? This book throws light on a problem-riddled Weber, a man lacerated by tragic contradictions, a great intellectual, nationalistic yet cosmopolitan. This investigation of his private life reveals a tender, impassioned man, who, at a time of overwhelming conflict, sought true life in love. (...) Whether Confucianism impeded the birth of modern capitalism in China remains a controversial issue. Equally problematic is the theory of the Calvinistic origins of European capitalism. Weber, however, answers both questions in an original manner, while also providing a lesson in methodology which remains unparalleled to date. A century after his death, Max Weber remains a controversial figure of political and social sciences. (shrink)
