Multiple theories of problem-solving hypothesize that there are distinct qualitative phases exhibited during effective problem-solving. However, limited research has attempted to identify when transitions between phases occur. We integrate theory on collaborative problem-solving with dynamical systems theory suggesting that when a system is undergoing a phase transition it should exhibit a peak in entropy and that entropy levels should also relate to team performance. Communications from 40 teams that collaborated on a complex problem were coded for occurrence of problem-solving processes. (...) We applied a sliding window entropy technique to each team's communications and specified criteria for identifying data points that qualify as peaks and determining which peaks were robust. We used multilevel modeling, and provide a qualitative example, to evaluate whether phases exhibit distinct distributions of communication processes. We also tested whether there was a relationship between entropy values at transition points and CPS performance. We found that a proportion of entropy peaks was robust and that the relative occurrence of communication codes varied significantly across phases. Peaks in entropy thus corresponded to qualitative shifts in teams’ CPS communications, providing empirical evidence that teams exhibit phase transitions during CPS. Also, lower average levels of entropy at the phase transition points predicted better CPS performance. We specify future directions to improve understanding of phase transitions during CPS, and collaborative cognition, more broadly. (shrink)

The study of human behavior is severely hampered by logistical problems, ethical and legal constraints, and funding shortfalls. However, the biggest difficulty of conducting social and behavioral research is the extraordinary complexity of the study phenomena. In this article, we review the impact of complexity on research design, hypothesis testing, measurement, data analyses, reproducibility, and the communication of findings in psychological science. The systematic investigation of the world often requires different approaches because of the variability in complexity. Confirmatory testing, multi-factorial (...) designs, survey methods, large samples, and modeling are frequently needed to study complex social and behavioral topics. Complexity impedes the measurement of general constructs, the reproducibility of results and scientific reporting, and the general rigor of research. Many of the benchmarks established by classic work in physical science are not attainable in studies of more complex phenomena. Consequently, the standards used to evaluate scientific research should be tethered to the complexity of the study topic. (shrink)

Dynamical simulations of male and female mating strategies illustrate how traits such as restrictedness constrain, and are constrained by, local ecology. Such traits cannot be defined solely by genotype or by phenotype, but are better considered as decision rules gauged to ecological inputs. Gangestad & Simpson's work draws attention to the need for additional bridges between evolutionary psychology and dynamical systems theory.

Davidson's account of weakness of will dependsupon a parallel that he draws between practicaland theoretical reasoning. I argue that theparallel generates a misleading picture oftheoretical reasoning. Once the misleadingpicture is corrected, I conclude that theattempt to model akratic belief on Davidson'saccount of akratic action cannot work. Thearguments that deny the possibility of akraticbelief also undermine, more generally, variousattempts to assimilate theoretical to practicalreasoning.

The knowledge norm of assertion is mainly in competition with a high probability or rational credibility norm. The argument for the knowledge norm that I offer turns on cases in which a hearer responds to a speaker's assertion by asserting another sentence that would lower the probability of the speaker's assertion, were its probability less than one. In cases like this, though with qualifications, is the hearer's contribution a challenge to the speaker's assertion or complementary to it? My answer is (...) the latter, and that only the knowledge norm yields that answer.The cases that I rely on follow from an elementary probability relation, though one that is inconsistent with the still influential relevance criterion for confirmation and evidence . Assume, for illustrative purposes, that p is in your belief corpus, as a consequence of your believing ∨ ∨ . 1 You learn that ∼ & ∼ , which would lessen the probability of p, were its probability less than one, 2 since it eliminates two rows of the truth-table in which p holds. What conclusion do you reach about p?Rather than withdrawing p, you acquire the belief that p & ∼ s & ∼ r, even though Formula where pr would be the subjective or epistemic probability of p on a probabilistic view of the knowledge norm before learning ∼ & ∼ . Instead of withdrawal …. (shrink)

A critique of conversational epistemic contextualism focusing initially on why pragmatic encroachment for knowledge is to be avoided. The data for pragmatic encroachment by way of greater costs of error and the complementary means to raise standards of introducing counter-possibilities are argued to be accountable for by prudence, fallibility and pragmatics. This theme is sharpened by a contrast in recommendations: holding a number of factors constant, when allegedly higher standards for knowing hold, invariantists still recommend assertion (action), while contextualists do (...) not. Given the knowledge norm of assertion, if one recommendation is preferable to the other, the result favors the preferred recommendation's account of knowledge. In the final section, I offer a unification of these criticisms centering on the contextualist use of 'epistemic position'. Their use imposes on threshold notions of justification, warrant, or knowledge tests that are suitable only to unlimited comparative or scalar notions like confidence or certainty and places them at one with an important strand of sceptical reasoning.

Fair lotteries offer familiar ways to pose a number of epistemological problems, prominently those of closure and of scepticism. Although these problems apply to many epistemological positions, in this paper I develop a variant of a lottery case to raise a difficulty with the reliabilist's fundamental claim that justification or knowledge is to be analyzed as a high truth-ratio (of the relevant belief-forming processes). In developing the difficulty broader issues are joined including fallibility and the relation of reliability to understanding.

A critical study of McPeck's recent book, in which he strengthens and develops his arguments against teaching critical thinking (CT). Accepting McPeck's basic claim that there is no unitary skill of reasoning or thinking, I argue that his strictures on CT courses or programs do not follow. I set out what I consider the proper justification that programs in CT have to meet, and argue both that McPeck demands much more than is required, and also that it is plausible that (...) this deflated justification can be met. Specitically, I argue that it is reasonable to expect transfer of learning for basic logical skills. Additional topics covered include: the relation ofliberal education to critical thinking, argument analysis, testing for CT, and the value of conceptual or linguistic analysis. (shrink)

This paper argues for the importance of the distinction between internal and external negation over expressions for belief. The common fallacy is to confuse statement like (1) and (2): (1) John believes that the school is not closed on Tuesday; (2) John does not believe that the school is closed on Tuesday. The fallacy has ramifications in teaching, reasoning, and argumentation. Analysis of the fallacy and suggestions for teaching are offered.

My critical comments focus mainly on premises,, and. However, in treating these I will address other of James’s assumptions—particularly, the presupposition of his argument that it is possible to will to believe. Later I will try to accommodate existential aspects of James’s argument that retain value, even if my objections to his argument stand.

A teoria das virtudes epistêmicas (VE) sustenta que as virtudes dos agentes, tais como a imparcialidade ou a permeabilidade intelectual, ao invés de crenças específicas, devem estar no centro da avaliação epistêmica, e que os indivíduos que possuem essas virtudes estão mais bem-posicionados epistemicamente do que se não as tivessem, ou, pior ainda, do que se tivessem os vícios correspondentes: o preconceito, o dogmatismo, ou a impermeabilidade intelectual. Eu argumento que a teoria VE padece de um grave defeito, porque fracassa (...) ao se ajustar à natureza social dos questionamentos (epistêmicos) típicos. Esse e outros defeitos relacionados a esse infectam o paralelo que os teóricos VE traçam entre virtudes epistêmicas e morais. Ao prometer o incremento na proporção de crenças verdadeiras sobre crenças falsas, ou ignorância, as virtudes epistêmicas não podem desempenhar um papel paralelo àquele que Aristóteles reserva às virtudes morais ao prometer o incremento em nossa felicidade e no bem-estar da comunidade. A minha rota para essas críticas é feita das razões sobre por que os agentes (sociais) devem buscar a obtenção de seus objetivos morais e epistêmicos diferentemente nos papéis que atribuem às virtudes. PALAVRAS-CHAVES – Virtude epistêmica. Divisão de trabalho epistêmico. Diversidade. Conhecimento. Falibilidade. Virtude moral. ABSTRACT Epistemic Virtue (EV) theory holds that virtues of agents, like impartiality or openmindedness, rather than specific beliefs, should be at the center of epistemological evaluation, and that individuals with those virtues are better positioned epistemically than if they lacked them or, worse, if they instead had the corresponding vices: prejudice, dogmatism, or close-mindedness. I argue that EV theory suffers from a serious flaw because it fails to accommodate to the social nature of typical (epistemic) inquiries. This and related flaws infect the parallel that EV theorists allege between epistemic and moral virtues. In promising to improve our ratio of true beliefs to either false beliefs or ignorance, the epistemic virtues cannot play a roll parallel to that which Aristotle claims for the moral virtues in promising to increase our happiness and the well-being of the community. The path to these criticisms I introduce by offering reasons for why (social) agents should seek to realize their epistemic and moral goals very differently in the respective roles they accord to the virtues. KEY WORDS – Epistemic virtue. Division of epistemic labor. Diversity. Knowledge. Fallibility. Moral virtue. (shrink)

Evidentialism implies that, for epistemic purposes, belief should be responsive only to evidence. Focusing on our reactive attitude such as resentment or indignation, I construct an argument that the beliefs or judgments accompanying those attitudes are constrained in advance by circumstances to be full, rather than being open to the whole range of partial beliefs. These judgments or beliefs imply strong claims to justification. But the circumstances in which those attitudes are formed allow only very limited evidence. Nevertheless, we cannot (...) opt out regularly since the formation of such attitudes is so central a feature of a minimally content human social life. (shrink)

An epistemic account of fallacies is one which takes it as a necessary condition for a fallacy that it has a tendency to produce false or unwarranted beliefs. The most sophisticated form of this account occurs in an article by Robert J. Fogelin and Timothy J. Duggan (“Fallacies,”Argumentation 1, 1987, pp. 255–262). I criticize the Fogelin and Duggan proposal, in particular, and epistemic accounts, more generally. Though an epistemic approach is attractive, it enlarges the class of fallacies, beyond what would (...) be permitted by traditional accounts. I also question thenecessity of fallacies leading to unwarranted beliefs. Some fallacies are fallacious due to their expected harm to argument practices. This position touches on a theme in the work of Van Eemeren and Grootendorst, though I criticize their notion of rules of argument as too broad. (shrink)

Defence of conditions to withdraw an assertion that require evidence or epistemic reasons that the assertion is not true or warranted. (Adler, J. 2006. Withdrawal and contextualism. Analysis 66: 280–85) The defence replies to the claim that better methods justify withdrawal without meeting that requirement and without pragmatic encroachment.

In Vol. XI, No.1, this journal announced an argument analysis contest. Two eminent colleagues agreed to serve as judges-Professor Henry W. Johnstone, Jr. and Professor Michael Scriven. In short order, four entries were received and sent off to the judges, who had no knowledge of the contestants' identities, and in due course the judges' verdicts were delivered. Immediately below we have reproduced the argument which was to be analyzed, along with the rules of the contest, followed by the four entries. (...) Thereafter we present the judges' rulings.

A much disputed conceptual argument aims to show the impossibility of direct believing at will. Regardless of the success of this argument, it has been held to be impotent against indirect forms of belief-control, such as by developing oneself to be more careful or fair-minded in evaluating evidence. However, the shift to indirect forms inherits difficulties connected to the conceptual argument.

The present argument assumes that teaching through modeling attempts to teach the intellectual virtues not primarily as an independent goal of education as, for example, a way to build good character, but for its value to inquiry. I argue that intellectual vices (such as being gullible, dogmatic, pigheaded, or prejudiced)—while harmful to inquiry in certain ways—are essential to its well functioning. Furthermore, to the extent that teaching models critical inquiry, there are educational lessons for which some students ought to take (...) a dogmatic or narrow minded commitment to certain hypotheses or positions; and then, insofar as this modeling works, it will promote these intellectual vices. In Part I of what follows, I develop my argument; in Part II, I respond to the objection that diversity of ideas and attitudes need not—and ought not—call upon the promotion of intellectual vices.
