Parasite stress and pathogen avoidance relate to distinct dimensions of political ideology across 30 nations

Significance Pathogens, and antipathogen behavioral strategies, affect myriad aspects of human behavior. Recent findings suggest that antipathogen strategies relate to political attitudes, with more ideologically conservative individuals reporting more disgust toward pathogen cues, and with higher parasite stress nations being, on average, more conservative. However, no research has yet adjudicated between two theoretical accounts proposed to explain these relationships between pathogens and politics. We find that national parasite stress and individual disgust sensitivity relate more strongly to adherence to traditional norms than they relate to support for barriers between social groups. These results suggest that the relationship between pathogens and politics reflects intragroup motivations more than intergroup motivations. People who are more avoidant of pathogens are more politically conservative, as are nations with greater parasite stress. In the current research, we test two prominent hypotheses that have been proposed as explanations for these relationships. The first, which is an intragroup account, holds that these relationships between pathogens and politics are based on motivations to adhere to local norms, which are sometimes shaped by cultural evolution to have pathogen-neutralizing properties. The second, which is an intergroup account, holds that these same relationships are based on motivations to avoid contact with outgroups, who might pose greater infectious disease threats than ingroup members. Results from a study surveying 11,501 participants across 30 nations are more consistent with the intragroup account than with the intergroup account. National parasite stress relates to traditionalism (an aspect of conservatism especially related to adherence to group norms) but not to social dominance orientation (SDO; an aspect of conservatism especially related to endorsements of intergroup barriers and negativity toward ethnic and racial outgroups). Further, individual differences in pathogen-avoidance motives (i.e., disgust sensitivity) relate more strongly to traditionalism than to SDO within the 30 nations.

Registered replication report: Rand, Greene, & Nowak

In an anonymous 4-person economic game, participants contributed more money to a common project (i.e., cooperated) when required to decide quickly than when forced to delay their decision (Rand, Greene & Nowak, 2012), a pattern consistent with the social heuristics hypothesis proposed by Rand and colleagues. The results of studies using time pressure have been mixed, with some replication attempts observing similar patterns (e.g., Rand et al., 2014) and others observing null effects (e.g., Tinghög et al., 2013; Verkoeijen & Bouwmeester, 2014). This Registered Replication Report (RRR) assessed the size and variability of the effect of time pressure on cooperative decisions by combining 21 separate, preregistered replications of the critical conditions from Study 7 of the original article (Rand et al., 2012). The primary planned analysis used data from all participants who were randomly assigned to conditions and who met the protocol inclusion criteria (an intent-to-treat approach that included the 65.9% of participants in the time-pressure condition and 7.5% in the forced-delay condition who did not adhere to the time constraints), and we observed a difference in contributions of −0.37 percentage points compared with an 8.6 percentage point difference calculated from the original data. Analyzing the data as the original article did, including data only for participants who complied with the time constraints, the RRR observed a 10.37 percentage point difference in contributions compared with a 15.31 percentage point difference in the original study. In combination, the results of the intent-to-treat analysis and the compliant-only analysis are consistent with the presence of selection biases and the absence of a causal effect of time pressure on cooperation.

Evaluating the role of attention in the context of unconscious thought theory: differential impact of attentional scope and load on preference and memory

Attention is a key process used to conceptualize and define modes of thought, but we lack information about the role of specific attentional processes on preferential choice and memory in multi-attribute decision making. In this study, we examine the role of attention based on two dimensions, attentional scope and load on choice preference strength and memory using a paradigm that arguably elicits unconscious thought. Scope of attention was manipulated by using global or local processing during distraction (Experiment 1) and before the information-encoding stage (Experiment 2). Load was manipulated by using the n-back task in Experiment 1. Results from Experiment 1 show that global processing or distributed attention during distraction results in stronger preference irrespective of load but better memory only at low cognitive load. Task difficulty or load did not have any effect on preference or memory. In Experiment 2, distributed attention before attribute encoding facilitated only memory but did not influence preference. Results show that attentional processes at different stages of processing like distraction and information-encoding influence decision making processes. Scope of attention not only influences preference and memory but the manner in which attentional scope influences them depends on both load and stage of information processing. The results indicate the important role of attention in processes critical for decision making and calls for a re-evaluation of the unconscious thought theory (UTT) and the need for reconceptualizing the role of attention.

Attribute Preference and Selection in Multi-Attribute Decision Making: Implications for Unconscious and Conscious Thought

Unconscious thought theory (UTT) states that all information is taken into account and the attributes are weighted optimally resulting in better decisions in complex decision problems during unconscious thought. Very few studies have investigated the actual amount of information processed in the unconscious thought condition. We hypothesized that only a small subset of information might be considered during unconscious thought (like conscious thought). To test this possibility and to explore the way attribute information is selected and combined, we performed computer simulations on the datasets used by previous researchers. The simulations showed that considering a small subset (3-4) of attributes, yields results comparable to previous studies. There is no need to posit infinite capacity in the unconscious thought condition. The results also suggest that weight information is used for attribute selection that could potentially explain the difficulties in replicating the deliberation-without-attention effect.

Money makes you reveal more: consequences of monetary cues on preferential disclosure of personal information

With continuous growth in information aggregation and dissemination, studies on privacy preferences are important to understand what makes people reveal information about them. Previous studies have demonstrated that short-term gains and possible monetary rewards make people risk disclosing information. Given the malleability of privacy preferences and the ubiquitous monetary cues in daily lives, we measured the contextual effect of reminding people about money on their privacy disclosure preferences. In experiment 1, we found that priming money increased willingness to disclose their personal information that could be shared with an online shopping website. Beyond stated willingness, experiment 2 tested whether priming money increases propensity for actually giving out personal information. Across both experiments, we found that priming money increases both the reported willingness and the actual disclosure of personal information. Our results imply that not only do short-term rewards make people trade-off personal security and privacy, but also mere exposure to money increases self-disclosure.

Attention in preferential choice.

Theoretical discussions and models of preferential choice have significantly improved our understanding of decision making over the past few decades. Although attention is a key cognitive mechanism that is often used in these theoretical discussions, formal treatment of attention is quite naïve. We bring to light how attention has been used explicitly and implicitly to conceptualize some generic modes of thought followed by a discussion of results from cognitive psychology on the interaction between attention and decision making. In the process, we discuss issues with theorizations regarding the role of attention. We suggest treating attention as a nonunitary mechanism, the possibility of incorporating subsampling as a generic heuristic based on attentional mechanisms and the necessity to consider the role of attentional scope in addition to the allocation of attention, that is, conceptualized in terms of resources. These discussions also bear upon the conceptual and formal treatment of preferential choice in particular and the psychology of decision making in general.

Price discount framings on product bundles with shipping surcharges in the Indian market

Purpose – The purpose of this paper is to study how consumers process price frames of product bundles (product plus surcharge) and discount offers to weigh contentious positions between the weighted-additive and the reference-dependent models. Further, some research suggests bundling, while others suggest partitioning to be a more effective pricing strategy. This research evaluated the relative influences of different price frames to examine which model is supported and what are the boundary conditions for price framing. Design/methodology/approach – Two online studies were conducted on Indian adults who had prior experiences of online purchases. They were asked to judge attractiveness of bundles (product along with shipping surcharge). Discounts were shown on the product, the surcharge or on the overall bundle either as partitioned prices or as a bundle. Findings – Across two studies on low- and high-priced products, discounts on shipping surcharge increased attractiveness of the bundle compared to a sim...

Role of Attention in Complex Decisions: Further Explorations of Unconscious Thought Theory

According to Unconscious Thought Theory (UTT) there are two modes of thought: Conscious and Unconscious. Unconscious Thought is defined as thought without attention or with attention directed elsewhere. More participants made better decisions following unconscious thought. According to UTT, unconscious thought does not have capacity limitations and takes in consideration all information which results in better decision. Studies on Unconscious Thought have not explored how much information is exactly processed during unconscious thought. It is possible that unconscious thought also focuses on a subset of attributes. To test this possibility and to further explore how attribute information is combined, computer simulations were performed on datasets used by previous researchers. The simulations showed that considering a small subset (3–4) of attributes, yields results comparable to previous studies. There is no need to posit infinite capacity in the unconscious thought condition. The results also suggest that weight information is used for attribute selection that could potentially explain the difficulties in replicating the deliberation-without-attention effect. UTT also tends to treat attention as a unitary mechanism and defines unconscious thought depending on whether attention is absent/not directed. Attention literature suggests that different types of attention (focused and distributed) affects cognitive processes differently. In another study, attention was manipulated during unconscious thought using a global-local task to explore whether it differently affects decisions. Strength of preference for the choice and memory of recall were both significantly higher in the global task group. Even quality of choice was better in the global-group but failed to reach significance. These results also suggest that unconscious Thought is neither purely online nor purely offline.

Perceptual Broadening Leads to More Prosociality

A link between perceptual processing styles and (pro)social behavior has gathered supporting empirical evidence to show that people raised or trained in traditions of collectiveness, compassion, and prosocial beliefs are biased to the global level in perceptual processing. In this research, we studied the reciprocal link – whether contextually broadening perceptual scope of attention via global processing could make people more prosocial. We hypothesized that global processing linked previously to an interdependent compassionate self-orientation would make people more prosocial, compared to local processing. Four experiments manipulated perceptual scope through a Global-Local task using hierarchical stimuli. It was found that participants who performed a global processing perceptual task volunteered to donate more money across different donation frames, compared to those who performed a local processing task. While previous research showed prosocial mindsets lead to perceptual broadening, the current results suggest that perceptual broadening also leads to more prosociality, thus establishing a reciprocal link between perceptual broadening (attentional scope), and acting prosocially. It is proposed that perceptual scope of attention is one of the generic cognitive processes that underlie prosocial decisions. Explanations based on scope of attention can potentially be used as a framework that enables researchers to link the effects of different contextual cues on prosocial decisions.

Nocebo effects from negative product information: When information hurts, paying money could heal

Purpose This research aimed to find whether information about a product can give rise to negative perceptions even in inert situations (nocebo effects), and to understand how price levels impact such judgments. Design/methodology/approach In all experiments, participants were exposed to negative product information in the form of potential side-effects. In an initial study, a higher non-discounted versus a discounted price frame was presented for a health drink after customers were exposed to negative aspects. Then, in experiment 1, price (high vs low) and exposure to information (no information vs negative information) was manipulated for skin creams where participants physically evaluated the cream. In experiment 2, price was manipulated at three levels (low, high, discounted) orthogonally with product information (no negative information vs with negative information) to get a more nuanced understanding. Findings In the initial study, after exposure to negative information, the non-discounted group had more positive ratings for the drink. Study 1 showed that reading about negative information resulted in a nocebo effect on perception of dryness (side-effect). Moreover, when no information was presented, perception of dryness by low and high price groups were similar but in the face of negative information, perception of dryness by low-price group was more pronounced compared to a high-price group. Study 2 conceptually replicated the effect and also confirmed that not only discounts (commonly linked with product quality), but absolute price levels also show a similar effect. Practical implications Nocebo effects have been rarely documented in consumer research. This research showed how simply reading generically about potential side effects gives rise to nocebo effects. In addition, even though marketers might find it tempting to lower prices when there is negative information about certain product categories, such an action could backfire. Originality/value To the best of our knowledge, the link between observable nocebo effects and its link with pricing actions is a novel research thread. We were able to show a nocebo effect on product perception after reading about negative information and also find that a higher price can mitigate the nocebo effect to some extent.
