Ideological diversity, hostility, and discrimination in philosophy

Members of the field of philosophy have, just as other people, political convictions or, as psychologists call them, ideologies. How are different ideologies distributed and perceived in the field? Using the familiar distinction between the political left and right, we surveyed an international sample of 794 subjects in philosophy. We found that survey participants clearly leaned left (75%), while right-leaning individuals (14%) and moderates (11%) were underrepresented. Moreover, and strikingly, across the political spectrum, from very left-leaning individuals and moderates to very right-leaning individuals, participants reported experiencing ideological hostility in the field, occasionally even from those from their own side of the political spectrum. Finally, while about half of the subjects believed that discrimination against left- or right-leaning individuals in the field is not justified, a significant minority displayed an explicit willingness to discriminate against colleagues with the opposite ideology. Our findings are both surprising and important, because a commitment to tolerance and equality is widespread in philosophy, and there is reason to think that ideological similarity, hostility, and discrimination undermine reliable belief formation in many areas of the discipline

Reforming rural education : understanding teacher expectations for rural youth

The Chinese state\u27s commitment to improve teaching quality in rural regions is a key component of national efforts to close the rural–urban education gap. In this paper, we investigate an understudied but critical dimension of quality teaching: teacher expectations. We employ longitudinal data gathered in Gansu Province in 2000 and 2007 to first examine whether teacher expectations for rural youth are conditioned by students’ social origin and teacher background characteristics. Next, we determine the predictive accuracy of their expectations. Our results highlight the ways in which teacher expectations condition the sorting of rural children among different schooling tracks with distinct life trajectories. Significantly, teachers are more likely to hold lower expectations for students from disadvantaged backgrounds. In addition, non-local teachers hold lower expectations for rural children compared to local teachers. Finally, a low percentage of teachers expect students to enroll in post-compulsory vocational education. We consider the implications of these results for both educational policy and social inequality

Predictably confirmatory: The influence of stereotypes during decisional processing.

Stereotypes facilitate the processing of expectancy-consistent (vs expectancy-inconsistent) information, yet the underlying origin of this congruency effect remains unknown. As such, here we sought to identify the cognitive operations through which stereotypes influence decisional processing. In six experiments, participants responded to stimuli that were consistent or inconsistent with respect to prevailing gender stereotypes. To identify the processes underpinning task performance, responses were submitted to a hierarchical drift diffusion model (HDDM) analysis. A consistent pattern of results emerged. Whether manipulated at the level of occupational (Expts. 1, 3, and 5) or trait-based (Expts. 2, 4, and 6) expectancies, stereotypes facilitated task performance and influenced decisional processing via a combination of response and stimulus biases. Specifically, (1) stereotype-consistent stimuli were classified more rapidly than stereotype-inconsistent stimuli; (2) stereotypic responses were favoured over counter-stereotypic responses (i.e., starting-point shift towards stereotypic responses); (3) less evidence was required when responding to stereotypic than counter-stereotypic stimuli (i.e., narrower threshold separation for stereotypic stimuli); and (4) decisional evidence was accumulated more efficiently for stereotype-inconsistent than stereotype-consistent stimuli and when targets had a typical than atypical facial appearance. Collectively, these findings elucidate how stereotypes influence person construal

The Role of Teachers' Expectations in the Association between Children's SES and Performance in Kindergarten: A Moderated Mediation Analysis

This study examines the role of teachers' expectations in the association between children's socio-economic background and achievement outcomes. Furthermore, the role of children's ethnicity in moderating this mediated relation is investigated. In the present study, 3,948 children from kindergarten are examined. Data are analysed by means of structural equation modeling. First, results show that teachers' expectations mediate the relation between children's SES and their later language and math achievement, after controlling for children's ethnicity, prior achievement and gender. This result indicates that teachers may exacerbate individual differences between children. Second, children's ethnicity moderates the mediation effect of teachers' expectations with respect to math outcomes. The role of teachers' expectations in mediating the relation between SES and math outcomes is stronger for majority children than for minority children

Beware ‘persuasive communication devices’ when writing and reading scientific articles

Authors rely on a range of devices and techniques to attract and maintain the interest of readers, and to convince them of the merits of the author’s point of view. However, when writing a scientific article, authors must use these ‘persuasive communication devices’ carefully. In particular, they must be explicit about the limitations of their work, avoid obfuscation, and resist the temptation to oversell their results. Here we discuss a list of persuasive communication devices and we encourage authors, as well as reviewers and editors, to think carefully about their use

The Effect of Corrective Feedback on Performance in Basic Cognitive Tasks: An Analysis of RT Components

[EN] The current work examines the effect of trial-by-trial feedback about correct and error responding on performance in two basic cognitive tasks: a classic Stroop task (n = 40) and a color-word matching task (n = 30). Standard measures of both RT and accuracy were examined in addition to measures obtained from fitting the ex-Gaussian distributional model to the correct RTs. For both tasks, RTs were faster in blocks of trials with feedback than in blocks without feedback, but this difference was not significant. On the other hand, with respect to the distributional analyses, providing feedback served to significantly reduce the size of the tails of the RT distributions. Such results suggest that, for conditions in which accuracy is fairly high, the effect of corrective feedback might either be to reduce the tendency to double-check before responding or to decrease the amount of attentional lapsing.Moret-Tatay, C.; Leth-Steensen, C.; Quarty-Irigaray, T.; Iracema De Lima-Argimon, I.; Gamermann ., D.; Abad Tortosa, D.; Oliveira, C....

Honesty, beliefs about honesty, and economic growth in 15 countries

The honesty of people in an online panel from 15 countries was measured in two experiments: reporting a coin flip with a reward for “heads”, and an online quiz with the possibility of cheating. There are large differences in honesty across countries. Average honesty is positively correlated with per capita GDP. This is driven mostly by GDP differences arising before 1950, rather than by GDP growth since 1950. A country’s average honesty correlates with the proportion of its population that is Protestant. These facts suggest a long-run relationship between honesty and economic development. The experiment also elicited participants’ expectations about different countries’ levels of honesty. Expectations were not correlated with reality. Instead they appear to be driven by cognitive biases, including self-projection
