Much research in the last two decades has demonstrated that human responses deviate from the performance deemed normative according to various models of decision making and rational judgment (e.g., the basic axioms of utility theory). This gap between the normative and the descriptive can be interpreted as indicating systematic irrationalities in human cognition. However, four alternative interpretations preserve the assumption that human behavior and cognition is largely rational. These posit that the gap is due to (1) performance errors, (2) computational (...) limitations, (3) the wrong norm being applied by the experimenter, and (4) a different construal of the task by the subject. In the debates about the viability of these alternative explanations, attention has been focused too narrowly on the modal response. In a series of experiments involving most of the classic tasks in the heuristics and biases literature, we have examined the implications of individual differences in performance for each of the four explanations of the normative/descriptive gap. Performance errors are a minor factor in the gap; computational limitations underlie non-normative responding on several tasks, particularly those that involve some type of cognitive decontextualization. Unexpected patterns of covariance can suggest when the wrong norm is being applied to a task or when an alternative construal of the task should be considered appropriate. Key Words: biases; descriptive models; heuristics; individual differences; normative models; rationality; reasoning. (shrink)

Natural myside bias is the tendency to evaluate propositions from within one's own perspective when given no instructions or cues (such as within-participants conditions) to avoid doing so. We defined the participant's perspective as their previously existing status on four variables: their sex, whether they smoked, their alcohol consumption, and the strength of their religious beliefs. Participants then evaluated a contentious but ultimately factual proposition relevant to each of these demographic factors. Myside bias is defined between-participants as the mean difference (...) in the evaluation of the proposition between groups with differing prior status on the variable. Whether an individual difference variable (such as cognitive ability) is related to the magnitude of the myside bias is indicated by whether the individual difference variable interacts with the between-participants status variable. In two experiments involving a total of over 1400 university students ( n = 1484) and eight different comparisons, we found very little evidence that participants of higher cognitive ability displayed less natural myside bias. The degree of myside bias was also relatively independent of individual differences in thinking dispositions. We speculate that ideas from memetic theory and dual-process theory might help to explain why natural myside bias is quite dissociated from individual difference variables. (shrink)

In this response, we clarify several misunderstandings of the understanding/acceptance principle and defend our specific operationalization of that principle. We reiterate the importance of addressing the problem of rational task construal and we elaborate the notion of computational limitations contained in our target article. Our concept of thinking dispositions as variable intentional-level styles of epistemic and behavioral regulation is explained, as is its relation to the rationality debate. Many of the suggestions of the commentators for elaborating two-process models are easily (...) integrated into our generic dual-process account. We further explicate how we view the relation between System 1 and System 2 and evolutionary and normative rationality. We clarify our attempt to fuse the contributions of the cognitive ecologists with the insights of the original heuristics and biases researchers. (shrink)

The Anglican Thirty Nine Articles join catholic Christendom in affirming that: There is but one living and true God…and in unity of this Godhead there be three Persons of one substance, power, and eternity; the Father, the Son, and the Holy Ghost.

Dual-process and dual-system theories in both cognitive and social psychology have been subjected to a number of recently published criticisms. However, they have been attacked as a category, incorrectly assuming there is a generic version that applies to all. We identify and respond to 5 main lines of argument made by such critics. We agree that some of these arguments have force against some of the theories in the literature but believe them to be overstated. We argue that the dual-processing (...) distinction is supported by much recent evidence in cognitive science. Our preferred theoretical approach is one in which rapid autonomous processes are assumed to yield default responses unless intervened on by distinctive higher order reasoning processes. What defines the difference is that Type 2 processing supports hypothetical thinking and load heavily on working memory. (shrink)

Discusses the rationality of the Christian religion and examines the philosophical arguments for the existence of God.

As a result of in-house discussions stimulated by previous Gonzaga engineering ethics conferences, Coffman Engineers began the implementation of what is to be a company-wide ethics training program. While preparing a curriculum aimed at consulting engineers, we found very little guidance as to how to proceed with most available literature being oriented towards the academic environment. We consulted a number of resources that address the teaching of engineering ethics in higher education, but questioned their applicability for the Consulting Engineering environment. (...) This lack of guidance led us to informal research into the ethical knowledge and attitudes of both consulting engineers and engineering students. Some of our findings were unexpected, and suggest that a simpler approach to teaching ethics to working professionals might be preferred to that typically promoted in higher education. (shrink)

Responds to the idea that humans are merely survival mechanisms for their own genes, providing the tools to advance human interests over the interests of the replicators through rational self-determination.

The cognitive critique of the goals and desires that are input into the implicit calculations that result in instrumental rationality is one aspect of what has been termed broad rationality (Elster, 1983). This cognitive critique involves, among other things, the search for rational integration (Nozick, 1993)—that is, consistency between first-order and second-order preferences. Forming a second-order preference involves metarepresentational abilities made possible by mental decoupling operations. However, these decoupling abilities are separable from the motive that initiates the cognitive critique itself. (...) I argue that Velleman (1992) has identified that motive (“the desire to act in accordance with reasons”), and that it might be operationalisable as a thinking disposition at a very superordinate cognitive level. This thinking disposition, the Master Rationality Motive, is likely to be of particular importance in explaining individual differences in the tendency to seek rational integration. Preliminary research on related constructs suggests that this construct is measurable. (shrink)

In an incisive critique of Professor Hick's Evil and the God of Love , Professor Puccetti claims to ‘carry the campaign as well as the battle’—i.e. to show that, with respect to evil, theists ‘are either “explaining it away” or saying it cannot be explained at all. And in both cases they are in effect admitting they have no rational defence to offer. Which means that despite appearances they really are abandoning the battlefield.’.

_Philosophy of Religion_ provides an account of the central issues and viewpoints in the philosophy of religion but also shows how such issues can be rationally assessed and in what ways competing views can be rationally assessed. It includes major philosophical figures in religious traditions as well as discussions by important contemporary philosophers. Keith Yandell deals lucidly and constructively with representative views from Judaism, Christianity, Islam, Hinduism, Buddhism, and Jainism. This book will appeal to students of both philosophy and (...) religion as well as to the general reader interested in the subject. Unique features of _Philosophy of Religion_: * key reading and new reading in the subject area * questions at the ends of chapters * a glossary of philosophical terms * annotated further reading.

Many critics of dual-process models have mistaken long lists of descriptive terms in the literature for a full-blown theory of necessarily co-occurring properties. These critiques have distracted attention from the cumulative progress being made in identifying the much smaller set of properties that truly do define Type 1 and Type 2 processing. Our view of the literature is that autonomous processing is the defining feature of Type 1 processing. Even more convincing is the converging evidence that the key feature of (...) Type 2 processing is the ability to sustain the decoupling of secondary representations. The latter is a foundational cognitive requirement for hypothetical thinking. (shrink)

The essay that follows considers two topics. After dealing with relevant preliminaries, it asks: (a) what differences are there in what must be done in order to tell whether there is any religious knowledge if an internalist evidentialist account of knowledge is true, from what must be done in order to tell whether there is any religious knowledge if an externalist reliabilist account of knowledge is true; and (b) does the best current externalist reliabilist account of knowledge require (or perhaps (...) already implicitly contain) an internalist evidentialist element? Put in a nutshell, then, a belief has warrant for a person S only if that belief is produced in S by cognitive faculties functioning properly (subject to no dysfunction) in a cognitive environment that is appropriate for S’s kind of cognitive faculties, according to a design plant that is successfully aimed at truth … when a belief meets these conditions and does enjoy warrant, the degree of warrant it enjoys depends on the strength of the belief, the degree of firmness with which S holds it. This is intended as an account of the central core of our concept of warrant … [Warranted Christian Belief, 156; implicit in reference to a design plan here is another feature—that the belief is subject to no undefeated defeaters; such a belief, if true, constitutes knowledge.].

The doctrine of hell, stated with a little care, entails that some persons never achieve their greatest good, fail to really flourish and never reach the end for which they were created. If that doctrine is true, and it is tragic that persons never achieve their greatest good, then there are tragic states of affairs whose tragedy is never overcome.

The preceding two sections have considered, respectively, the discreditation of psychological belief, and of propositional belief, which begins with the claim that a belief possessed by some person is non-epistemically explicable and ends with the claim that that person is unreasonable or that that belief is (probably) false. Obviously, only certain strategies of discreditation were discussed, and those only partially. But if the examples of discrediting strategies were representative, and the remarks made about them were correct, what, if anything, follows?It (...) seems clear that the sheer fact that a person's belief is non-epistemically explicable entails very little if anything about the person's reasonability in holding it or the probable falsehood of the belief in question. Nor does the fact that a basic belief is held without reason or grounds seem to speak against the rationality of its believer - not at least with respect to the sort of propositions we called structural. It does not follow that one cannot rationally assess competing structural beliefs - that is another, and given the present argument an entirely open, question. It does seem correct that the more restrictive axioms of the ethics of properly held basic beliefs are ill-suited to deal responsibly with the acceptance of structural propositions. And at least some religious propositions - God exists among them - seem to me to be of that sort. Of course, that raises the question of what, exactly, a structural proposition is - which, again, is another topic.If the argument of this essay is correct, the shift from considering whether some particular (and perhaps idiosyncratic) person is reasonable in accepting some proposition, in cases where this is an interesting and debateable matter, to whether (on the whole) this proposition is one that can be accepted without rendering oneself unreasonable, seems to be an issue usually not capable of rational resolution without engaging in some sort of direct assessment of the proposition believed, and the strategy of trying to escape this by considering whether a person's acceptance of that proposition can be non-epistemically explained seems, on the whole, not a profitable enterprise. Further, often, at least, it can be countered in one or another of the ways we considered in the preceding two sections. So I am inclined to view the attempt to settle interesting debates about whether a person is reasonable in accepting a proposition by arguing that his acceptance is non-epistemically explicable as, on the whole, a failure.If anything, things are worse, so far as I can see, for attempts to argue from the fact that a person's belief is non-epistemically explicable to the conclusion that it is probably false. For, again, this argument has force only if the fact that this person's acceptance of it is non-epistemically explicable is not idiosyncratic, and this is establishable, often at least, only by appealing to the results of a direct assessment of the proposition believed (or by offering a judgment on this matter without benefit of any assessment, which of course is worthless). Nor, of course, is the nonepistemic explicability of a person's belief that P sufficient to discredit the person, let alone P, and the sorts of properties that are often alleged to accompany non-epistemically explicable beliefs seem either in fact not to accompany them, or to accompany only a basically irrelevant and uninteresting sub-set of them, or not to be such as to make falsehood of the propositions whose belief they accompany probable.A final comment These remarks, at best, scratch the surface of a difficult and complex topic. It is a topic on which, so far as I am aware, not a great deal has been written. My hope is that what I have said here may stimulate sufficient interest in the topic for others to provide a further exploration of the issues that I have here only been able to highlight. (shrink)

The plasma membrane of polarized epithelial cells is divided into apical and basolateral surfaces, with different compositions. Proteins can be sent directly from the trans‐Golgi network (TGN) to either surface, or can be sent first to one surface and then transcytosed to the other. The glycosyl phosphatidylinositol anchor is a signal for apical targeting. Signals in the cytoplasmic domain containing a β‐turn determine basolateral targeting and retrieval, and are related to other sorting signals. Transcytosed proteins, such as the polymeric immunoglobulin (...) receptor (plgR), are endocytosed from the basolateral surface and then accumulate in a tubular compartment concentrated underneath the apical surface. This compartment, tentatively termed the apical recycling compartment, may be a central sorting station, as it apparently receives material from both surfaces and sorts them for delivery to the correct surface. Delivery to the apical surface from both the TGN and the apical recycling compartment appears to be regulated by protein kinases A and C, and endocytosis from the apical surface is also regulated by kinases. Transcytosis of the plgR is additionally regulated by phosphorylation of the plgR and by ligand binding to the plgR. Regulation of traffic in polarized epithelial cells plays a central role in cellular homeostasis, response to external signals and differentiation. (shrink)

There is another sort of ‘defense’ of relativism that I mention in conclusion. Sometimes one finds the view that one is rightly punished for a crime only if they admit committing it, and that it was a crime — something wrongly done: ‘punishment conditional on confession’ is the rule proposed. It might seem that this would give impunity to a criminal hardy enough to deny the fact, or the evil, of her deed; so it would, unless it was also understood (...) that if a person was proved by accepted standards to be the perpetrator of an action agreed to be wrong, the opportunity to admit guilt would extend from open questioning through beating to exquisite torture until confession was extracted (cf. the Chinese customs reflected in the Judge Dee stories of Robert Van Gulik). More often, one finds the view that a person is not refuted unless he admits this, and a view is not refuted — and so is not properly dismissed — unless its proponents concede defeat. A similar view is that all really telling philosophical criticism must be internal or else non-neutral (a view we discussed above).If one can in principle produce a conceptual system from a list of all propositions by following the recipe: for any proposition P include P, or else include not-P, in S, then (providing one adds no constraints concerning consistency) there will be no proposition that will appear in all conceptual systems. If what it is for a proposition to be neutral is for it to appear in all conceptual systems, then no proposition is neutral. But of course, the same recipe that produces this result produces the result that the proposition (P) Some proposition is both true and false appears in some conceptual system which (since the denial of (P) appears in less than all systems and hence is not neutral) is (allegedly) none the worse for that. And the proposition (P1) Conceptual relativism is false appears in some conceptual systems which (since the denial of (P1) appears in less than all systems and hence is not neutral) is none the worse for that. But then what remains of the claim that conceptual relativism is true?Sometimes refuted is used in a person-independent manner: Proposition P is (and always was) refuted by the fact that F uses P is refuted in such a way that it does not entail There is someone who refuted P. Sometimes, of course, it is so used that P is refuted does have that entailment. Even in the latter case, refutation is an epistemological notion, and Person S is refuted does not entail S knows that S is refuted and is compatible with S believes that S is not refuted. The recommendation that we add a psychological component of ‘admits to’ to the epistemological notion ‘being refuted’ seems to have no other ground than the arbitrary one that if we do we shall then be able better to defend relativism.While the recipe for constructing conceptual systems suggested above may seem useful to a relativist — it gives one clear content to ‘neutral proposition’ — it has what must surely seem a defect to the relativist, namely that given it (even with consistency constraints added) there will be no translational incommensurability. For if P is contained in system S, then not-P is expressible in S, and conversely. And the recipe yields the result that for any proposition P, and any system S, S contains either P or else not-P.This, of course, brings out an ambiguity in ‘contains’. In one sense, a system ‘contains (1)’ whatever can be expressed in it. In another, it ‘contains (2)’ whatever, according to it, is true. If it is a complete system without suspense of judgment it contains (1) twice the propositions it contains (2). Further, a system contains (1) lots of propositions it (or its proponent) does not regard as true, and so the fact that a proposition P appears in system S does not mean that P favors S. One often at least can state the conditions of S's falsehood in S, and even prove in S that S is false, where “in” is used in the sense of “contains (1).”Sophisticated relativism, then, seems no more plausible, no more free from inconsistency, and no less open to devastating critique than are its less cultured relatives. Relativism, at least in the varieties discussed here, seems to live up to its unsavory reputation. Since not even translation incommensurability seems to entail lack of cognitive competitiveness, it seems that it will have to be admitted that, regarding apparent disagreement on basic matters — including fundamental religious disagreement — the appearance is also the reality. People do uneliminably disagree, and short of conversion or (what will seem from within the religious perspective in question) some other ‘failure in faith’ (e.g., coming to reject all religious views) will continue to do so. Whatever can be done in terms of common understanding and common humanitarian endeavors must be done without denying the many basic disagreements that there are. And whatever notion of inter-faith dialogue is other than espitemically defective will have to face that fact; for significant dialogue based on self-deception or on falsehood seems not a terribly promising enterprise.

Crossculturally, monotheistic traditions view God as occupying the apex of power, knowledge and goodness, and as enjoying independent existence. This conceptual context provides room for maneuvering concerning God’s nature (e.g., does God have logically necessary existence?) and God’s creatures (e.g., do created persons have libertarian freedom?). Logical consistency is always a constraint on such maneuvering. With that constraint in mind, our purpose here is to consider different conceptual maneuvers concerning God, created persons, and freedom (both human and divine) within Christian (...) and Hindu Vedantic monotheism.

HUME’S CLAIMS REGARDING THE QUERY "IS IT EVER REASONABLE TO BELIEVE THAT A MIRACLE HAS OCCURRED?" ARE FASCINATINGLY COMPLEX. THIS ESSAY ATTEMPTS TO TAKE ACCOUNT OF THE VARIETY OF CLAIMS HE OFFERS, STATING EACH ARGUMENT AND THEN APPRAISING ITS SUCCESS. SINCE WHAT HUME SAYS HAS INTERESTING ANALOGIES AND APPLICATIONS TO CONTEMPORARY ISSUES IN THE PHILOSOPHY OF SCIENCE AND THE EPISTEMOLOGY OF RELIGIOUS BELIEF, THESE ARE ALSO DISCUSSED.

The dissociation of fluid cognitive functions from g is implicit in the Cattell-Horn-Carroll gF-gC theory. Nevertheless, Blair is right that fluid functions are extremely important. I suggest that the key mental operation assessed by measures of gF is the ability to sustain mental simulation while keeping the relevant representations decoupled from the actual world – an ability that underlies all hypothetical thinking.
