Recent psychological research has identified important individual differences associated with receptivity to bullshit, which has greatly enhanced our understanding of the processes behind susceptibility to pseudo-profound or otherwise misleading information. However, the bulk of this research attention has focused on cognitive and dispositional factors related to bullshit (the product), while largely overlooking the influences behind bullshitting (the act). Here, we present results from four studies (focusing on the construction and validation of a new, reliable scale measuring the frequency with which individuals engage in two types of bullshitting (persuasive and evasive) in everyday situations. Overall, bullshitting frequency was negatively associated with sincerity, honesty, cognitive ability, open-minded cognition, and self-regard. Additionally, the Bullshitting Frequency Scale was found to reliably measure constructs that are: 1) distinct from lying, and; 2) significantly related to performance on overclaiming and social decision tasks. These results represent an important step forward by demonstrating the utility of the Bullshitting Frequency Scale as well as highlighting certain individual differences that may play important roles in the extent to which individuals engage in everyday bullshitting.

The study aimed to investigate the status of within-person state variability in neuroticism and conscientiousness as individual differences constructs by exploring their (a) temporal stability, (b) cross-context consistency, (c) empirical links to selected antecedents, and (d) empirical links to longer term trait variability. Employing a sample of professionals ( N = 346) from Australian organisations, personality state data together with situation appraisals were collected using experience sampling methodology in field and repeatedly in lab-like settings. Data on personality traits, cognitive ability, and motivational mindsets were collected at baseline and after two years. Contingent (situation contingencies) and non-contingent (relative SD) state variability indices were relatively stable over time and across contexts. Only a small number of predictive effects of state variability were observed, and these differed across contexts. Cognitive ability appeared to be associated with state variability under lab-like conditions. There was limited evidence of links between short-term state and long-term trait variability, except for a small effect for neuroticism. Some evidence of positive manifold was found for non-contingent variability. Systematic efforts are required to further elucidate the complex pattern of results regarding the antecedents, correlates and outcomes of individual differences in state variability.

The current study examined whether offloading prospective memory (PM) demands onto the environment through the use of reminders eliminates PM differences typically seen between individuals that have poor or good working memory ability. Over two laboratory sessions scheduled one week apart, participants completed three versions of a PM offloading task with and without the use of reminders, along with multiple measures of working memory. Participants also generated a list of naturalistic intentions to fulfill between sessions and were given an intention to email the experimenter every day. They later indicated which intentions were completed with and without the use of reminders. Consistent with prior research, high working memory participants did better in both laboratory and naturalistic settings when having to rely on their own memory. Critically, however, working memory ability was no longer predictive of performance with the use of reminders. Participants with lower working memory also offloaded more often that high ability participants, but this was not optimally calibrated to actual PM performance. These findings suggest that offloading may be particularly beneficial for those with poor cognitive ability. The theoretical and applied ramifications of these findings are discussed.

The “cognitive miser” metaphor is a classic characterization of mental life wherein cognitive efficiency is favored over careful and reflective thinking. A presumed implication is that reliance on intuitive processing in the absence of reflective thinking should encourage stereotyping. However, research to date has not adequately tested whether proclivities to engage reflective thinking correspond with less stereotype endorsement, nor if their influence occurs independent of cognitive ability and epistemic motivation. In two studies, we conducted straightforward tests of this hypothesis by measuring individual differences in miserly or reflective thinking, cognitive ability, and epistemic motivation as unique predictors of stereotype endorsement. We utilized objective, performance-based measures of reflective thinking via the Cognitive Reflection Test. The results provide the first direct evidence for the cognitive miser hypothesis. Individual differences in miserly thinking predicted endorsements of racial/ethnic stereotypes independent of cognitive ability and epistemic motivation.

Individual differences in learning can influence how animals respond to and communicate about their environment, which may nonlinearly shape how a social group accomplishes a collective task. There are few empirical examples of how differences in collective dynamics emerge from variation among individuals in cognition. Here, we use a naturally variable and heritable learning behavior called latent inhibition (LI) to show that interactions among individuals that differ in this cognitive ability drive collective foraging behavior in honey bee colonies. We artificially selected two distinct phenotypes: high-LI bees that ignore previously familiar stimuli in favor of novel ones and low-LI bees that learn familiar and novel stimuli equally well. We then provided colonies differentially composed of different ratios of these phenotypes with a choice between familiar and novel feeders. Colonies of predominantly high-LI individuals preferred to visit familiar food locations, while low-LI colonies visited novel and familiar food locations equally. Interestingly, in colonies of mixed learning phenotypes, the low-LI individuals showed a preference to visiting familiar feeders, which contrasts with their behavior when in a uniform low-LI group. We show that the shift in feeder preference of low-LI bees is driven by foragers of the high-LI phenotype dancing more intensely and attracting more followers. Our results reveal that cognitive abilities of individuals and their social interactions, which we argue relate to differences in attention, drive emergent collective outcomes.
