High intelligence: A risk factor for psychological and physiological overexcitabilities

High intelligence: A risk factor for psychological and physiological overexcitabilities. Ruth I. Karpinski et al. Intelligence, https://doi.org/10.1016/j.intell.2017.09.001

Highlights
•    A potential association between a hyperbrain (high IQ) and a hyperbody was examined.
•    Those with high IQ had higher risk for psychological disorders (RR 1.20 - 223.08).
•    High IQ was associated with higher risk for physiological diseases (RR 1.84 - 4.33).
•    Findings lend substantial support to a hyper brain/hyper body theory.

Abstract: High intelligence is touted as being predictive of positive outcomes including educational success and income level. However, little is known about the difficulties experienced among this population. Specifically, those with a high intellectual capacity (hyper brain) possess overexcitabilities in various domains that may predispose them to certain psychological disorders as well as physiological conditions involving elevated sensory, and altered immune and inflammatory responses (hyper body). The present study surveyed members of American Mensa, Ltd. (n = 3715) in order to explore psychoneuroimmunological (PNI) processes among those at or above the 98th percentile of intelligence. Participants were asked to self-report prevalence of both diagnosed and/or suspected mood and anxiety disorders, attention deficit hyperactivity disorder (ADHD), autism spectrum disorder (ASD), and physiological diseases that include environmental and food allergies, asthma, and autoimmune disease. High statistical significance and a remarkably high relative risk ratio of diagnoses for all examined conditions were confirmed among the Mensa group 2015 data when compared to the national average statistics. This implicates high IQ as being a potential risk factor for affective disorders, ADHD, ASD, and for increased incidence of disease related to immune dysregulation. Preliminary findings strongly support a hyper brain/hyper body association which may have substantial individual and societal implications and warrants further investigation to best identify and serve this at-risk population.

The Impact of Physical Dominance on Male Customers’ Status-Signaling Consumption

The Abercrombie & Fitch Effect: The Impact of Physical Dominance on Male Customers’ Status-Signaling Consumption. Tobias Otterbring et al. Journal of Marketing Research. In-Press, https://doi.org/10.1509/jmr.15.0247

Abstract: Consumer lay theory suggests that women will spend more money than men in the presence of a physically dominant male employee, while theories of intrasexual competition from evolutionary psychology predict the opposite outcome. A retail field study demonstrates that male customers spend more money and purchase more expensive products than their female counterparts in the presence (vs. absence) of a physically dominant male employee. This effect has a more powerful impact on male customers who lack bodily markers of dominance (shorter stature or measures linked to lower levels of testosterone). When confronted with other physically dominant (vs. non-dominant) men, these male customers are particularly prone to signal status through price or logo size. Their elevated feelings of intrasexual (male-to-male) competitiveness drive them to spend more money on status-signaling, but not functional products, and to prefer and draw larger brand logos. As pictorial exposure is sufficient for the effect to occur, these findings are not limited to in-store interactions with dominant male employees, but have broad implications for marketing and advertising.

Origins of sinister rumors: A preference for threat-related material in the supply and demand of information

Origins of sinister rumors: A preference for threat-related material in the supply and demand of information. Timothy Blaine, Pascal Boyer. Evolution and Human Behavior, https://doi.org/10.1016/j.evolhumbehav.2017.10.001

Highlights
•    Risk-related rumors are more common than benefit-related rumors.
•    Threat information is more often transmitted than non-threatening negative information.
•    Also, people seek additional information about threats more than about other topics.
•    This could explain why so many rumors are about potential danger.

Abstract: Many rumors convey information about potential danger, even when these dangers are very unlikely. In four studies, we examine whether micro-processes of cultural transmission explain the spread of threat-related information. Three studies using transmission chain protocols suggest a) that there is indeed a preference for the deliberate transmission of threat-related information over other material, b) that it is not caused by a general negativity or emotionality bias, and c) that it is not eliminated when threats are presented as very unlikely. A forced-choice study on similar material shows the same preference when participants have to select information to acquire rather than transmit. So the cultural success of threat-related material may be explained by transmission biases, rooted in evolved threat-detection and error-management systems, that affect both supply and demand of information.
