In two large samples, we found a positive relationship between disgust sensitivity and political conservatism. This relationship held when controlling for a number of demographic variables as well as the “Big Five” personality traits. Disgust sensitivity was also associated with more conservative voting in the 2008 U.S. presidential election. In Study 2, we replicated the disgust sensitivity–conservatism relationship in an international sample of respondents from 121 different countries. Across both samples, contamination disgust, which reflects a heightened concern with interpersonally transmitted (...) disease and pathogens, was most strongly associated with conservatism. (shrink)

Gender differences in perceived quality of employment are examined. The study asks whether women’s occupations provide better conditions in areas that facilitate their dual role in society, as a trade-off for low monetary rewards. Specifically, it examines the association of women’s concentration in broader occupational categories, embedded in particular national contexts, with gender differences in job quality. Utilizing the 2005 ISSP modules on work orientation shows that women lag behind men on most dimensions of job quality, countering the hypothesis that (...) women’s occupations compensate for their low wages and limited opportunities for promotion by providing better employment conditions. However, as women’s relative share in occupations grows the gender gap narrows in most job quality dimensions. The implications of these results are discussed. (shrink)

Perceiving others? minds is a crucial component of social life. People do not, however, always ascribe minds to other people, and sometimes ascribe minds to non-people. This article reviews when mind perception occurs, when it does not, and why mind perception is important. Causes of mind perception stem both from the perceiver and perceived, and include the need for social connection and a similarity to oneself. Mind perception also has profound consequences for both the perceiver and perceived. Ascribing mind confers (...) an entity moral rights and also makes its actions meaningful. Understanding the causes and consequences of mind perception can explain when this most social of cognitive skills will be used, and why it matters. (shrink)

Using contemporary data from the U.S. and other nations, we address 3 questions: Do gender differences in mathematics performance exist in the general population? Do gender differences exist among the mathematically talented? Do females exist who possess profound mathematical talent? In regard to the first question, contemporary data indicate that girls in the U.S. have reached parity with boys in mathematics performance, a pattern that is found in some other nations as well. Focusing on the second question, studies find more (...) males than females scoring above the 95th or 99th percentile, but this gender gap has significantly narrowed over time in the U.S. and is not found among some ethnic groups and in some nations. Furthermore, data from several studies indicate that greater male variability with respect to mathematics is not ubiquitous. Rather, its presence correlates with several measures of gender inequality. Thus, it is largely an artifact of changeable sociocultural factors, not immutable, innate biological differences between the sexes. Responding to the third question, we document the existence of females who possess profound mathematical talent. Finally, we review mounting evidence that both the magnitude of mean math gender differences and the frequency of identification of gifted and profoundly gifted females significantly correlate with sociocultural factors, including measures of gender equality across nations.

The relationship among age, education, gender, syllogistic reasoning skill, epistemic beliefs, and moral reasoning in adults was examined. It was predicted that five epistemic dimensions would explain unique variance in moral reasoning over and above all other variables. This hypothesis was confirmed. Beliefs corresponding to simple knowledge, certain knowledge, omniscient authority, and quick learning each explained the significant variation in performance on the Defining Issues Test. Results showed that multiple epistemic assumptions play an important role in young adults' moral reasoning (...) over and above other social and personal variables. Implications concerning the development of epistemic beliefs are discussed. (shrink)

This paper reports results from a randomized experiment in which 256 participants recruited to complete a survey could earn extra payment by cheating on a quiz. We report the first deterrence experiment that incorporates significant elements of situational and individual difference theories of crime into a single analytic framework. Consistent with extant deterrence research, the prevalence of cheating was lower when detection was more certain but not when the penalty was more severe. Further, cheating was more likely among participants with (...) stronger present-orientation, or who were prone to self-serving bias. (shrink)

A well-established phenomenon in reasoning research is matching bias : a tendency to select information that matches the lexical content of propositional statements, regardless of the logically critical presence of negations. Previous research suggested, however, that the effect might be restricted to reasoning with conditional statements. This paper reports two experiments in which participants were required to construct or identify true and false cases of propositional rules of several kinds, including universal statements, disjunctions, and negated conjunctions. Matching bias was observed (...) across all rule types but largely restricted to problems where participants were required to falsify rather than to verify the rules. A third experiment showed a similar generalization across linguistic forms in the Wason selection task with only if conditionals substituted for universals. The results are discussed with reference to contemporary theories of propositional reasoning. (shrink)

Criticizes R. E. Nisbett and T. D. Wilson's counterintuitive argument on theoretical and methodological grounds. It is suggested that inappropriate statistical tests were used and that their argument was stated in a nonfalsifiable position. In addition, it is also argued that causality was incorrectly defined, other essential definitions were missing, and that other evidence opposes their theory.

Armchair philosophers have questioned the significance of recent work in experimental philosophy by pointing out that experiments have been conducted on laypeople and undergraduate students. To challenge a practice that relies on expert intuitions, so the armchair objection goes, one needs to demonstrate that expert intuitions rather than those of ordinary people are sensitive to contingent facts such as cultural, linguistic, socio-economic, or educational background. This article does exactly that. Based on two empirical studies on populations of 573 and 203 (...) trained philosophers, respectively, it demonstrates that expert intuitions vary dramatically according to at least one contingent factor, namely, the linguistic background of the expert: philosophers make different intuitive judgments if their native language is English rather than Dutch, German, or Swedish. These findings cast doubt on the common armchair assumption that philosophical theories based on armchair intuitions are valid beyond the linguistic background against which they were developed.

Meta-analyses were performed on 100 studies of gender differences in mathematics performance and 70 studies of gender differences in mathematics-related attitudes and affect. For mathematics performance, the average effect size across all studies was 0.15, indicating a slightly better performance by males. For mathematics-related attitudes and affect, the average effect sizes tended to be small, with females reporting more negative attitudes and affect. The one exception to this pattern was the stereotyping of math as a male domain, for which the (...) average effect size was −0.90, indicating that males hold a much more stereotyped attitude. Gender differences in mathematics performance, attitudes, and affect appear to be only small to moderate. Consequently, we must look beyond abilities and attitudes to explain the substantial underrepresentation of females in advanced mathematics classrooms and mathematics-related careers. (shrink)

What do philosophers think about arguments for the existence of God? To find out, I launched a survey among professional philosophers. This is a short summary of the results.

One of the important questions cognitive theories of reasoning must address is whether logical reasoning is inherently sentential or spatial. A sentential model would exploit nonspatial properties of representations whereas a spatial model would exploit spatial properties of representations. In general terms, the linguistic hypothesis predicts that the language processing regions underwrite human reasoning processes, and the spatial hypothesis suggests that the neural structures for perception and motor control contribute the basic representational building blocks used for high-level logical and linguistic (...) reasoning. We carried out a [15O] H2O PET imaging study to address this issue. (shrink)

: Using 1994-1995 and 2002-2003 data, Nieswiadomy found that economics majors scored well on the LSAT. These results are frequently posted on university web sites by Economics and other departments. This note, which updates the prior studies using current 2007-2008 data for the 2008-2009 class of students entering law school, finds that Economics majors still perform at or near the top of all majors taking the test. Economics majors are tied for first of the 12 largest disciplines. Economics is tied (...) for second ) behind Physics/Math in a set of 29 discipline groupings that are created to yield at least 450 students with similar majors. (shrink)

Two experiments investigated inferences based on suppositions. In Experiment 1, the subjects decided whether suppositions about individuals' veracity were consistent with their assertions—for example, whether the supposition “Ann is telling the truth and Beth is telling a lie”, is consistent with the premises: “Ann asserts: I am telling the truth and Beth is telling the truth. Beth asserts: Ann is telling the truth”. It showed that these inferences are more difficult than ones based on factual premises: “Ann asserts: I live (...) in Dublin and Beth lives in Dublin”. There was no difference between problems about truthtellers and liars, who always told the truth or always lied, and normals, who sometimes told the truth and sometimes lied. In Experiment 2, the subjects made inferences about factual matters set in three contexts: a truth-inducing context in which friends confided their personality characteristics, a lie-inducing context in which business rivals advertised their products, and a neutral context in which computers printed their program characteristics. Given the supposition that the individuals were lying, it was more difficult to make inferences in a truth-inducing context than in the other two contexts. We discuss the implications of our results for everyday reasoning from suppositions, and for theories of reasoning based on models or inference rules. (shrink)

The adequacy of the common attribute-value representation for knowledge about concepts was examined in two experiments. The first experiment used a verification task with true, plausible false, and implausible false sentences. Decisions about remote false sentences were faster than those for close false sentences. In the second experiment, pairs consisting of a concept name and a numerical property value were presented for reasonableness judgments. Numerical values varied over five levels of remoteness from the concepts' most typical values. Decision times increased (...) with remoteness from the most typical value for “yes” decisions and decreased with remoteness for “no” decisions. The results did not support a discrete-value representation or decision model for concepts. An alternative exemplar testing model was outlined. (shrink)

Moral judgment depends critically on theory of mind, reasoning about mental states such as beliefs and intentions. People assign blame for failed attempts to harm and offer forgiveness in the case of accidents. Here we use fMRI to investigate the role of ToM in moral judgment of harmful vs. helpful actions. Is ToM deployed differently for judgments of blame vs. praise? Participants evaluated agents who produced a harmful, helpful, or neutral outcome, based on a harmful, helpful, or neutral intention; participants (...) made blame and praise judgments. In the right temporo-parietal junction, and, to a lesser extent, the left TPJ and medial prefrontal cortex, the neural response reflected an interaction between belief and outcome factors, for both blame and praise judgments: The response in these regions was highest when participants delivered a negative moral judgment, i.e., assigned blame or withheld praise, based solely on the agent's intent. These results show enhanced attention to mental states for negative moral verdicts based exclusively on mental state information. (shrink)

Dual Process Theories of reasoning posit that judgments are mediated by both fast, automatic processes and more deliberate, analytic ones. A critical, but unanswered question concerns the issue of monitoring and control: When do reasoners rely on the first, intuitive output and when do they engage more effortful thinking? We hypothesised that initial, intuitive answers are accompanied by a metacognitive experience, called the Feeling of Rightness, which can signal when additional analysis is needed. In separate experiments, reasoners completed one of (...) four tasks: conditional reasoning, a three-term variant of conditional reasoning, problems used to measure base rate neglect, or a syllogistic reasoning task. For each task, participants were instructed to provide an initial, intuitive response to the problem along with an assessment of the rightness of that answer. They were then allowed as much time as needed to reconsider their initial answer and provide a final answer. In each experiment, we observed a robust relationship between the FOR and two measures of analytic thinking: low FOR was associated with longer rethinking times and an increased probability of answer change. In turn, FOR judgments were consistently predicted by the fluency with which the initial answer was produced, providing a link to the wider literature on metamemory. These data support a model in which a metacognitive judgment about a first, initial model determines the extent of analytic engagement. (shrink)

Being socially connected has considerable benefits for oneself, but may have negative consequences for evaluations of others. In particular, being socially connected to close others satisfies the need for social connection, and creates disconnection from more distant others. We therefore predicted that feeling socially connected would increase the tendency to dehumanize more socially distant others. Four experiments support this prediction. Those led to feel socially connected were less likely to attribute humanlike mental states to members of various social groups, particularly (...) distant others compared to close others, and were also more likely to recommend harsh treatment for dehumanized others. Discussion addresses the mechanisms by which social connection enables dehumanization, and the varied behavioral implications that result. (shrink)

Experimental Philosophy: Volume 2 contains fourteen articles -- thirteen previously published and one new -- that reflect the fast-moving changes in the field over the last five years. The field of experimental philosophy is one of the most innovative and exciting parts of the current philosophical landscape; it has also engendered controversy. Proponents argue that philosophers should employ empirical research, including the methods of experimental psychology, to buttress their philosophical claims. Rather than armchair theorizing, experimental philosophers should go into the (...) field to research how people actually think and reason. In a sense this is a return to a view of philosophy as the progenitor of psychology: inherently concerned with the human condition, with no limits to its scope or methods. In the course of the last decade, many experimental philosophers have overturned assumptions about how people think in the real world. This volume provides an essential guide to the most influential recent work on this vital and exciting area of philosophical research. (shrink)

In this reply, we provide an analysis of Alter et al. response to our earlier paper. In that paper, we reported difficulty in replicating Alter, Oppenheimer, Epley, and Eyre’s main finding, namely that a sense of disfluency produced by making stimuli difficult to perceive, increased accuracy on a variety of reasoning tasks. Alter, Oppenheimer, and Epley argue that we misunderstood the meaning of accuracy on these tasks, a claim that we reject. We argue and provide evidence that the tasks were (...) not too difficult for our populations and point out that in many cases performance on our tasks was well above chance or on a par with Alter et al.’s participants. Finally, we reiterate our claim that the distinction between answer fluency and perceptual fluency is genuine, and argue that Thompson et al. provided evidence that these are distinct factors that have different downstream effects on cognitive processes.

Moral judgments, whether delivered in ordinary experience or in the courtroom, depend on our ability to infer intentions. We forgive unintentional or accidental harms and condemn failed attempts to harm. Prior work demonstrates that patients with damage to the ventromedial prefrontal cortex deliver abnormal judgments in response to moral dilemmas and that these patients are especially impaired in triggering emotional responses to inferred or abstract events, as opposed to real or actual outcomes. We therefore predicted that VMPC patients would deliver (...) abnormal moral judgments of harmful intentions in the absence of harmful outcomes, as in failed attempts to harm. This prediction was confirmed in the current study: VMPC patients judged attempted harms, including attempted murder, as more morally permissible relative to controls. These results highlight the critical role of the VMPC in processing harmful intent for moral judgment. (shrink)

The personalistic theory of probability prescribes that a person should use personal probability assessments in decision-making and that these assessments should correspond with his judgments. Since the judgments exist solely in the assessor's mind, there is no way to prove whether or not this requirement is satisfied. De Finetti has proposed the development of methods which should oblige the assessor to make his assessments correspond with his judgments. An ideal Assessor is hypothesized and his behavior is investigated under a number (...) of such methods. The implications of these methods for the theory of personal probability are discussed. Finally, although the present interest is primarily normative, the practicability of the methods is also discussed. (shrink)

Evans and Stanovich propose that Type 1 processes should be defined in terms of autonomy, such that they are initiated and run to completion in the presence of relevant triggering conditions. In this commentary, I argue that their autonomous execution has implications for the nature of the representation that is formed and for the shape and outcome of subsequent Type 2 processes. In addition, I argue that Type 2 processes may also be triggered automatically, but that, unlike Type 1 processes, (...) their completion requires working memory resources, and that the outcome of those processes is more flexible than that of Type 1 processes.

Five experiments, with 163 university students, investigated 2 theories of conditional reasoning. The pragmatic schema theory posits that CDR is mediated by context-sensitive inference rules. According to the contextual cuing theory, inferences are based on a mental model that represents necessity and sufficiency relations. Both schematic relations and necessity relations predicted responses on a 4-card selection task. In contrast, after the effects of perceived necessity had been partialled out, schematic relations did not predict responses to either a conditional arguments task (...) or a task in which Ss judged the similarity of "if then" and "only if" statements. Findings question the assumption that reasoning is mediated by schematic rules, which presumably apply regardless of task. A reconceptualization of the pragmatic reasoning schema is proposed.

A major challenge for Dual Process Theories of reasoning is to predict the circumstances under which intuitive answers reached on the basis of Type 1 processing are kept or discarded in favour of analytic, Type 2 processing (Thompson 2009 ). We propose that a key determinant of the probability that Type 2 processes intervene is the affective response that accompanies Type 1 processing. This affective response arises from the fluency with which the initial answer is produced, such that fluently produced (...) answers give rise to a strong feeling of rightness. This feeling of rightness, in turn, determines the extent and probability with which Type 2 processes will be engaged. Because many of the intuitions produced by Type 1 processes are fluent, it is common for them to be accompanied by a strong sense of rightness. However, because fluency is poorly calibrated to objective difficulty, confidently held intuitions may form the basis of poor quality decisions. (shrink)

Subjects were asked to assess their subjective probability distributions for unknown parameters of Bernoulli processes. The processes were generated by random devices like, for instance, irregular dice. The assessments were based on two assessment techniques. One asked for the median and quartiles of the distributions, the other asked for the impact of four hypothetical samples. The main purpose of the study was to study the resulting two sets of distributions. The results show substantial differences between the distributions using the two (...) techniques but these differences decreased as the experiment progressed. (shrink)

Apparent evidence that awareness regularly mediates verbal conditioning actually may by attributable to a self-fulfilling experimental methodology. A more appropriate procedure was devised in which a subtle reversal of the roles of S and E distracted the actual S from acquiring the problem-solving set characteristic of previous methods. This "double-agent" approach was established in the context of an interview. The interviewer considered himself the E, and was told that his assignment was to reinforce a particular motor response in the interviewee. (...) The interviewee was in fact the E; he used that motor response to reinforce a particular choice of verbal prompt in the interviewer. Thereby, the double-agent interviewee was able to accomplish seven reversals in the relative rates of 2 of the interviewer's prompts. Frequent probing of the interviewer indicated that he was not aware of these changes in his own behavior, and that he had other irrelevant hypotheses to explain his variable apparent success in reinforcing the interviewee's motor response. Variable success in obtaining the effect across Ss may eventually be accounted for by parameters of the setting and by the S's other characteristic uses of the verbal responses chosen for study. Thus, the results indicate that verbal operant conditioning can occur without awareness in some persons, and that a person may unknowingly let his verbal behavior be controlled by another person in order to himself gain control over certain aspects of the other's behavior.

Paranormal beliefs are often divided between those that are central to traditional Christian doctrine, such as the belief in heaven and hell, and those that are commonly associated with the supernatural or occult, such as the belief in ESP and psychic healing. This study employs data from a recent nationwide random sample general population survey to catalog the social correlates of paranormal beliefs and to examine the relationships between religious and other paranormal beliefs. The results indicate that standard social background (...) factors do a poor job of accounting for who believes in paranormal phenomena and that the importance of specific background factors changes dramatically from phenomenon to phenomenon. The results also show that the correlations between belief in religious phenomena and other paranormal phenomena are largely insignificant. These findings call into question many prevailing theories about paranormal beliefs. (shrink)

Class inclusion, the conjunction fallacy, and other phenomena are presented to illustrate cognitive illusions, that reasoning can be misdirected so that errors of judgment violate known principles. Errors in class inclusion are traced to accessing and implementing logical knowledge, rather than logical deficits, memory overload, or misleading questions. It is argued that superordinate-set cuing does not afford subset comparisons, but, rather, facilitates implementation of logical knowledge. According to fuzzy-trace theory, successful performance involves applying the cardinality principle, but also suppressing solutions (...) based on judgments of relative numerosity, in which horizontal relationships between classes are apt to usurp the role of vertical ones.

In a paper recently published in Intelligence, Razmyar and Reeve found that participants with more analytic cognitive styles reported lower religiosity on a range of measures. Importantly, however, cognitive style did not add unique effects to the prediction of religiosity once cognitive ability was taken into account; a finding that is inconsistent with previous research on the topic. However, the authors failed to discuss this inconsistency and, in fact, only cited one of the many relevant papers on the topic. The (...) relevant paper that was cited, Shenhav, Rand, and Greene, was also not accurately represented, making it difficult to draw informed conclusions about their results. In this commentary, I review the evidence that indicates a unique relation between cognitive style and religious belief. This review highlights recent developments in the field as a means to situate Razmyar and Reeve's finding in the current literature. I conclude by drawing on this research to discuss the potential reasons for Razmyar and Reeve's discrepant results. (shrink)

Recent research has indicated a negative relation between the propensity for analytic reasoning and religious beliefs and practices. Here, we propose conflict detection as a mechanism underlying this relation, on the basis of the hypothesis that more-analytic people are less religious, in part, because they are more sensitive to conflicts between immaterial religious beliefs and beliefs about the material world. To examine cognitive conflict sensitivity, we presented problems containing stereotypes that conflicted with base-rate probabilities in a task with no religious (...) content. In three studies, we found evidence that religiosity is negatively related to conflict detection during reasoning. Independent measures of analytic cognitive style also positively predicted conflict detection. The present findings provide evidence for a mechanism potentially contributing to the negative association between analytic thinking and religiosity, and more generally, they illustrate the insights to be gained from integrating individual-difference factors and contextual factors to investigate analytic reasoning.

We provide evidence that religious skeptics, as compared to believers, are both more reflective and effective in logical reasoning tasks. While recent studies have reported a negative association between an analytic cognitive style and religiosity, they focused exclusively on accuracy, making it difficult to specify potential underlying cognitive mechanisms. The present study extends the previous research by assessing both performance and response times on quintessential logical reasoning problems. Those reporting more religious skepticism made fewer reasoning errors than did believers. This (...) finding remained significant after controlling for general cognitive ability, time spent on the problems, and various demographic variables. Crucial for the purpose of exploring underlying mechanisms, response times indicated that skeptics also spent more time reasoning than did believers. This novel finding suggests a possible role of response slowing during analytic problem solving as a component of cognitive style that promotes overriding intuitive first impressions. Implications for using additional processing measures, such as response time, to investigate individual differences in cognitive style are discussed. (shrink)

Some U.S. school districts are experimenting with single-sex schooling, hoping that it will yield better academic outcomes for students. Empirical research on the effects of single-sex schooling, however, has been equivocal, with various studies finding benefits, disadvantages, or no effect. Most of this research is marred because families generally choose whether the child attends a single-sex or coeducational school, so there are selection effects that create pre-existing differences between students in the different types of schools. The research reported here capitalized (...) on the case of Korea, where students are randomly assigned to single-sex or coeducational schools. Using 2007 Trends in International Mathematics and Science Study data, we applied hierarchical linear modeling to account for the nesting of students within schools. Results for eighth graders indicated no differences between students in single-sex and coeducational schools in mathematics and science achievement. Results from the 2003 TIMSS data replicated the finding: students' mathematics and science achievement was unrelated to the gender composition of their school. These results call into question whether single-sex schooling has the academic advantages claimed by its proponents. (shrink)

Human reasoning is often biased by stereotypical intuitions. The nature of such bias is not clear. Some authors claim that people are mere heuristic thinkers and are not aware that cued stereotypes might be inappropriate. Other authors claim that people always detect the conflict between their stereotypical thinking and normative reasoning, but simply fail to inhibit stereotypical thinking. Hence, it is unclear whether heuristic bias should be attributed to a lack of conflict detection or a failure of inhibition. We introduce (...) a neuroscientific approach that bears on this issue. Participants answered a classic decision-making problem while the activation of brain regions believed to be involved in conflict detection and response inhibition was monitored. Results showed that although the inhibition area was specifically activated when stereotypical responses were avoided, the conflict-detection area was activated even when people reasoned stereotypically. The findings suggest that people detect their bias when they give intuitive responses. (shrink)

British psychologists have been at the forefront of research into human reasoning for 40 years. This article describes some past research milestones within this tradition before outlining the major theoretical positions developed in the UK.

In our concluding comments we outline the challenges for (...) future research posed by this problem. (shrink)
