We begin with a discussion of consumers’ attitudes toward taxes and how they influence decisions to comply with tax payments that regulators can neither directly monitor nor enforce with certainty (e.g., taxes on incomes that are “off the books”). Next, we examine how taxes can shape consumer preferences and purchasing choices. We then consider key demographic variables that seem to moderate consumers’ sensitivity to taxes. We conclude by discussing future directions of research and some unanswered questions.

Preventing these fatalities should be a priority for policymakers, because death is irreversible, and survival necessarily precedes other forms of human welfare. Minimizing fatalities requires that policymakers respond to deadly events and that they effectively focus their attention, efforts, and life-saving resources on preventing the largest (aggregated) death tolls. However, the deployment of any major intervention, even one designed to save lives, requires sufficient political will, which in turn depends on people being moved to action by the number of lives at risk. All else being equal, responses to deadly events should be proportional to their potential death tolls, and support for life-saving interventions should grow steadily with the number of lives they are expected to save. Unfortunately, people’s reactions to deadly events generally fall short of these principles and instead reveal systematic limitations in their ability to properly evaluate human fatalities. This article discusses some of the cognitive factors that govern, and often skew, the way people perceive and respond to deadly events. I show that our failures to correctly prioritize and address the biggest causes of human casualties are driven by limitations and biases in perception, attention, and categorization. Understanding these psychological fallibilities will help policymakers recognize, and ultimately guard against, biases that hinder the deployment of important life-saving policies.

Nevertheless, our impressions of people are shaped by their facial appearances and, consequently, so too are these social decisions. This article summarizes research linking facial morphological traits to important social outcomes and discusses various factors that moderate this relationship.

Recent studies have shown that surprisingly little time and effort are needed to arrive at this consensus. Here we review recent research on so- cial attributions from faces. Section I outlines data-driven methods capable of identifying the perceptual basis of consensus in social attributions from faces (e.g., What makes a face look threatening?). Section II describes non- perceptual determinants of social attributions (e.g., person knowledge and incidental associations). Section III discusses evidence that attributions from faces predict important social outcomes in diverse domains (e.g., investment decisions and leader selection). In Section IV, we argue that the diagnostic validity of these attributions has been greatly overstated in the literature. In the final section, we offer an account of the functional significance of these attributions.

We argue that Bentley et al.’s timely account should consider the full breadth, and, above all, the predictive power of big data.

Building upon a recent study by Preis, Moat, Stanley, and Bishop (2012), we used search engine query data to construct measures of the time-perspective of nations, and tested these measures against per-capita gross domestic product (GDP). The results indicate that nations with higher per-capita GDP are more focused on the future and less on the past, and that when these nations do focus on the past, it is more likely to be the distant past. These results demonstrate the viability of using nation-level data to build psychological constructs.

However, much less is known about the accuracy or meta-accuracy of face-based leadership infer- ences. Here we examine a simple, but important, question: Can leadership domain be inferred from faces? We find that human judges can identify business, military, and sports leaders (but not political leaders) from their faces with above-chance accuracy. However, people are sur- prisingly bad at evaluating their own performance on this judgment task: We find no relationship between how well judges think they performed and their actual accuracy levels. In a follow-up study, we identify several basic dimensions of evaluation that correlate with face-based judgments of leadership domain, as well as those that predict actual leadership domain. We discuss the implications of our results for leadership perception and selection.

We report two studies exploring the effects of streaks in symptom checklists on perceived personal disease risk. In the context of these studies, a streak is a sequence of consecutive items on a list that share the characteristic of being either general or specific. We identify a psychological mechanism underlying the effect of streaks in a list of symptoms and show that the effect of streaks on perceived risk varies with the length of the symptom list.

In these patience auctions, participants bid the smallest future sum they would prefer-or-the longest time they would wait for a reward, rather than receive a smaller, immediate payoff. The most patient bidder receives the delayed reward; all others receive the immediate payoff. These auctions, in addition to offering certain potential methodological advantages, allow us to compare discounting when participants' attention is focused on the temporal vs.

However, since voters cannot objectively evaluate politicians’ personality traits, it remains to be seen whether appearance-based inferences about a characteristic continue to influence voting when clear information about that characteristic is available. The authors examine the impact of appearance-based inferences for a characteristic that is well known about candidates: their political affiliation. Across two studies, the authors show that U.S. candidates facing conservative electorates benefit from looking more stereotypically Republican than their rivals (controlling for gender, ethnicity, and age). In contrast, no relationship between political facial stereotypes and voting is found for liberal electorates (using identical controls). The authors further show that this contrast between liberal and conservative electorates has more to do with individual-level differences between liberal and conservative voters than with macro-level differences between liberal and conservative states.

Many human interactions are built on trust, so widespread confidence in first impressions generally favors individuals with trustworthy-looking appearances. However, few studies have explicitly examined: 1) the contribution of unfakeable facial features to trust-based decisions, and 2) how these cues are integrated with information about past behavior.
Methodology/Principal Findings:
Using highly controlled stimuli and an improved experimental procedure, we show that unfakeable facial features associated with the appearance of trustworthiness attract higher investments in trust games. The facial trustworthiness premium is large for decisions based solely on faces, with trustworthy identities attracting 42% more money (Study 1), and remains significant though reduced to 6% when reputational information is also available (Study 2). The face trustworthiness premium persists with real (rather than virtual) currency and when higher payoffs are at stake (Study 3).
Conclusions/Significance:
Our results demonstrate that cooperation may be affected not only by controllable appearance cues (e.g., clothing, facial expressions) as shown previously, but also by features that are impossible to mimic (e.g., individual facial structure). This unfakeable face trustworthiness effect is not limited to the rare situations where people lack any information about their partners, but survives in richer environments where relevant details about partner past behavior are available.

However, many people strongly dislike paying taxes. Although this distaste could be rational on economic grounds, the authors show that this attitude extends beyond simply disliking the costs incurred and affects behavior in coun- ternormative ways. They demonstrate the phenomenon of tax aversion: a desire to avoid taxes per se that exceeds the rational economic moti- vation to avoid a monetary cost. Across five experiments, the authors provide evidence that people have a stronger preference to avoid tax- related costs than to avoid equal-sized (or larger) monetary costs unre- lated to taxes. Tax aversion affects consumer preferences in a variety of domains, including standard store purchases, financial investments, and job selection. Furthermore, this tendency is most prevalent among people who identify with political parties that generally favor less taxation. Finally, encouraging participants who identify with “antitax” parties to consider positive uses of their tax payments mitigates tax aversion. This article concludes with a discussion of the implications of these results for consumer behavior research and tax policies.

In contrast to this widely held view, we provide evidence that the prospect of enduring pain and exerting effort for a prosocial cause can promote contributions to the cause. Specifically, we show that willingness to contribute to a charitable or collective cause increases when the contribution process is expected to be painful and effortful rather than easy and enjoyable. Across five experiments, we document this “martyrdom effect,” show that the observed patterns defy standard economic and psychological accounts, and identify a mediator and moderator of the effect. Experiment 1 showed that people are willing to donate more to charity when they anticipate having to suffer to raise money. Experiment 2 extended these findings to a non-charity laboratory context that involved real money and actual pain. Experiment 3 demonstrated that the martyrdom effect is not the result of an attribute substitution strategy (whereby people use the amount of pain and effort involved in fundraising to determine donation worthiness). Experiment 4 showed that perceptions of meaningfulness partially mediate the martyrdom effect. Finally, Experiment 5 demonstrated that the nature of the prosocial cause moderates the martyrdom effect: the effect is strongest for causes associated with human suffering. We propose that anticipated pain and effort lead people to ascribe greater meaning to their contri- butions and to the experience of contributing, thereby motivating higher prosocial contributions. We conclude by considering some implications of this puzzling phenomenon.
