Individual differences in receptivity to scientific bullshit

Pseudo-profound bullshit receptivity is the tendency to perceive meaning in important-sounding, nonsense statements. To understand how bullshit receptivity differs across domains, we develop a scale to measure scientific bullshit receptivity — the tendency to perceive truthfulness in nonsensical scientific statements. Across three studies (total N = 1,948), scientific bullshit receptivity was positively correlated with pseudo-profound bullshit receptivity. Both types of bullshit receptivity were positively correlated with belief in science, conservative political beliefs, and faith in intuition. However, compared to pseudoprofound bullshit receptivity, scientific bullshit receptivity was more strongly correlated with belief in science, and less strongly correlated with conservative political beliefs and faith in intuition. Finally, scientific literacy moderated the relationship the two types of bullshit receptivity; the correlation between the two types of receptivity was weaker for individuals scoring high in scientific literacy

Promoting VET teachers’ individual and social learning activities: the empowering and purposeful role of transformational leadership, interdependence, and self-efficacy

Background This study explores the interaction between organizational and psychological factors that play a role in professional teacher learning. More specifically, how teachers’ engagement in learning activities (e.g. keeping up to data, self-reflection, and experimenting, respectively, asking for feedback and information sharing) is influenced by the organizational factors transformational leadership and perceived interdependence, and the psychological factor self-efficacy. Methods The study is conducted in the context of Vocational Education and Training (VET) colleges in the Netherlands, using a survey among 447 VET teachers working in 66 teams. Results Results showed that self-efficacy and task interdependence directly, and positively, influence a variety of learning activities. Task interdependence influenced self-efficacy positively. Goal interdependence influenced self-efficacy positively, but from the learning activities it only affected information sharing and social reflection positively. From the transformational leadership practices vision building positively affected goal interdependence, and consideration and stimulation positively affected task interdependence. Conclusions In general, two configurations for the facilitation of teacher learning were found: one that empowers individual teachers to acquire new knowledge, and another that helps teachers to focus on shared goals and binds them to social learning. Teachers’ engagement in learning activities, and consequently VET colleges’ change capacities, is optimally facilitated by empowerment and purpose

Confirmation bias and misconceptions: Pupillometric evidence for a confirmation bias in misconceptions feedback

It has long been supposed that the confirmation bias plays a role in the prevalence and maintenance of misconceptions. However, this has been supported more by argument than by empirical evidence. In the present paper, we show how different types of belief-feedback evoke physiological responses consistent with the presence of a confirmation bias. Participants were presented with misconceptions and indicated whether they believed each misconception to be true or false, as well as how committed they were to the misconception. Each response was followed by feedback that was either clear (i.e., “correct” or “incorrect”) or ambiguous (i.e., “partly correct” or “partly incorrect”). Pupillary response to each feedback condition was assessed. The results show an interaction between feedback accuracy and feedback clarity on pupil size. The largest pupil size was found in response to clear disconfirmatory feedback. The smallest pupil size was found in response to both clear and ambiguous confirmatory feedback. Crucially, the pupil responded to ambiguous confirmatory feedback as though it were wholly confirmatory. Moreover, pupil size in response to ambiguous disconfirmatory feedback was significantly smaller than response to clear disconfirmatory feedback, showing an overall trend towards confirmatory processing in the absence of clear disconfirmation. Additionally, we show a moderation by commitment towards the misconception. The greater the commitment, the larger the effect of belief-violating feedback on pupil size. These findings support recent theorizing in the field of misconceptions and, more generally, the field of inconsistency-compensation

Emotions and behavioral intentions in response to ostracism attributed to a perceived lack of warmth versus competence

Individuals who are ostracized (i.e., ignored or excluded by others) experience a range of negative emotions and show various coping behaviors. We investigated whether target attributions of warmth and competence as perceived reasons for ostracism were differently related to emotions and behavioral intentions. In Study 1, participants (N = 321) recalled a nonspecific ostracism experience. We found no evidence that warmth and competence attributions were distinctly related to emotions or behavioral intentions. In Study 2, participants (N = 294) were instructed to recall being ostracized for specific reasons (warmth vs. competence). Ostracism attributed to incompetence evoked stronger feelings of anger and less prosocial intentions. Moreover, across both studies, targets primarily felt sad and wanted to withdraw regardless of the perceived reasons for ostracism. In contrast to more explicit forms of exclusion such as rejection, responses to warmth and competence attributions of ostracism may only become more distinguishable depending on context

The EMIF-AD Multimodal Biomarker Discovery study: design, methods and cohort characteristics.

There is an urgent need for novel, noninvasive biomarkers to diagnose Alzheimer's disease (AD) in the predementia stages and to predict the rate of decline. Therefore, we set up the European Medical Information Framework for Alzheimer's Disease Multimodal Biomarker Discovery (EMIF-AD MBD) study. In this report we describe the design of the study, the methods used and the characteristics of the participants. Participants were selected from existing prospective multicenter and single-center European studies. Inclusion criteria were having normal cognition (NC) or a diagnosis of mild cognitive impairment (MCI) or AD-type dementia at baseline, age above 50 years, known amyloid-beta (Aβ) status, availability of cognitive test results and at least two of the following materials: plasma, DNA, magnetic resonance imaging (MRI) or cerebrospinal fluid (CSF). Targeted and untargeted metabolomic and proteomic analyses were performed in plasma, and targeted and untargeted proteomics were performed in CSF. Genome-wide SNP genotyping, next-generation sequencing and methylation profiling were conducted in DNA. Visual rating and volumetric measures were assessed on MRI. Baseline characteristics were analyzed using ANOVA or chi-square, rate of decline analyzed by linear mixed modeling. We included 1221 individuals (NC n = 492, MCI n = 527, AD-type dementia n = 202) with a mean age of 67.9 (SD 8.3) years. The percentage Aβ+ was 26% in the NC, 58% in the MCI, and 87% in the AD-type dementia groups. Plasma samples were available for 1189 (97%) subjects, DNA samples for 929 (76%) subjects, MRI scans for 862 (71%) subjects and CSF samples for 767 (63%) subjects. For 759 (62%) individuals, clinical follow-up data were available. In each diagnostic group, the APOE ε4 allele was more frequent amongst Aβ+ individuals (p &lt; 0.001). Only in MCI was there a difference in baseline Mini Mental State Examination (MMSE) score between the A groups (p &lt; 0.001). Aβ+ had a faster rate of decline on the MMSE during follow-up in the NC (p &lt; 0.001) and MCI (p &lt; 0.001) groups. The characteristics of this large cohort of elderly subjects at various cognitive stages confirm the central roles of Aβ and APOE ε4 in AD pathogenesis. The results of the multimodal analyses will provide new insights into underlying mechanisms and facilitate the discovery of new diagnostic and prognostic AD biomarkers.
