Choice Set Size Shapes Self-Expression.

Across six studies (total N = 3,549), we find that participants who were randomly assigned to choose from larger assortments thought their choices were more self-expressive, an effect that emerged regardless of whether larger sets actually enabled participants to better satisfy their preferences. Studies examining the moderating role of choice domain and cultural context show that the effect of choice set size on perceived self-expression may be particular to contexts in which choices have some initial potential to express choosers' identities. We then test novel predictions from this theoretical perspective, finding that self-expression mediates the effect of choice set size on choice satisfaction, the likelihood of publicly sharing choices, and the perceived importance of choices. Together, these studies show that choice set size shapes perceived self-expression and illustrate how this meaning-based theoretical lens provides both novel explanations for existing effects and novel predictions for future research.

The framing of decisions "leaks" into the experiencing of decisions.

We connect Bermúdez's arguments to previous theorizing about "leaky" rationality, emphasizing that the decision process (including decision frames) "leaks" into the experience of decision outcomes. We suggest that the implications of Bermúdez's analysis are broadly applicable to the study of virtually all real-world decision making, and that the field needs a substantive and not just a formal theory of rationality.

Balancing the Freedom-Security Trade-Off During Crises and Disasters.

During crises and disasters, such as hurricanes, terrorist threats, or pandemics, policymakers must often increase security at the cost of freedom. Psychological science, however, has shown that the restriction of freedom may have strong negative consequences for behavior and health. We suggest that psychology can inform policy both by elucidating some negative consequences of lost freedom (e.g., depression or behavioral reactance) and by revealing strategies to address them. We propose four interlocking principles that can help policymakers restore the freedom-security balance. Careful consideration of the psychology of freedom can help policymakers develop policies that most effectively promote public health, safety, and well-being when crises and disasters strike.

Idea Technology and Ideology.

Although we are accustomed to thinking about technology as involving things-objects and processes-derived from scientific discoveries, science also creates a technology of ideas, ways of thinking both about the world and about human beings. And unlike "thing technology," "idea technology" can have powerful effects even when the ideas are false. This paper discusses false idea technology, or ideology, and suggests mechanisms by which it can have effects on both individuals and societies. It discusses neuroscience as the "next frontier" of ideology that may change our conceptions of human nature.

Effects of addiction science on conceived freewill and responsibility.

Although there is speculation that medicalization of addiction undermines conceived agency, only relatively modest effects have been reported. Research participants generally have ideas about addiction that are informed both by personal experience and by media, and their views may not be wholly updated in response to study-information. Here we examine the potential impact of addiction science theories on perceived volition and responsibility by considering the issues in the context of a hypothetical new drug, "Z." Participants (N = 662) were provided one of three functional accounts that each corresponded to a prominent theory within addiction science: incentive-sensitization, impaired self-control, and habit-system dominance. For half of participants, additional neuroscience mechanism information was included with the functional account. Across explanations, the inclusion of mechanism information was associated with significantly less perceived volition and marginal reduction in blame, For several measures, there was a significant or marginally significant interaction between which addiction explanation was used and whether mechanism information was included, with mechanism generally having the largest impact given the impaired self-control explanation of addiction and little evidence of impact given the incentive-sensitization explanation of addiction. Taken together, these results suggest robust effects of addiction science on judgments of agency when presented in the context of a novel addiction. It is unclear whether a sustained scientific consensus around an existing theory could produce a similar impact on how people understand real addictive behavior.

Comparing Practice Management Courses in Canadian Dental Schools.

Practice management has become an increasingly important aspect of dental education over the years in order to better prepare students for the reality of practice. The aim of this study was to quantify and describe practice management courses taught at the ten Canadian dental schools in order to identify common approaches, compare hours, determine types of instructors, and assess the relationship between courses' learning objectives and the Association of Canadian Faculties of Dentistry (ACFD) competencies and Bloom's cognitive levels. The academic deans at these ten schools were surveyed in 2016; all ten schools responded for a 100% response rate. The authors also gathered syllabi and descriptions of the courses and analyzed them for themes. The results showed a total of 22 practice management courses in the ten Canadian dental schools. The courses provided 27 to 109 hours of teaching and were mostly taught in the third and fourth years and by dentists on three main topics: ethics, human resource management, and running a private practice. The courses were correlated to the ACFD competencies related to ethics, professionalism, application of basic principles of business practices, and effective interpersonal communication. Most of the courses' learning objectives addressed comprehension and knowledge in Bloom's cognitive levels of learning. These results can help to guide discussions on how practice management courses can be developed, improved, and refined to meet the challenges of preparing students for dental practice.

A new science of happiness: the paradox of pleasure.

The pursuit of happiness is enshrined in the founding document of our nation as a fundamental and inalienable right. Yet nowhere is the method of this pursuit clearly defined. What, exactly, does it mean to be happy, and how can such happiness be sustained over the long term? Can happiness be accurately gauged or measured? How does the paradoxical relationship between happiness and pleasure shape our quest to lead the good life? And what does modern science have to tell us about this universal yet elusive pursuit? Steve Paulson, executive producer and host of To the Best of Our Knowledge, moderated a discussion that included attorney and author Kim Azzarelli, historian Darrin McMahon, and social psychologist Barry Schwartz, who joined forces to share their research and insight on happiness, pleasure, and the coveted good life.

On Klatzky and Creswell (2014): saving social priming effects but losing science as we know it?

Klatzky and Creswell (2014) offer an interpretation of the unreliability of social priming effects by analogizing them to what is known about the complexity of cross-modal transfer effects in perception. The complexity of these transfer effects arises because they are both multiply determined and stochastic. In this commentary, I argue that Klatzky and Creswell's thoughtful contribution raises the possibility that there might be deep and substantive limits to both the replicability and the generalizability of many of the phenomena that most interest psychologists, including social priming effects. Psychological phenomena largely governed by what Fodor (1983) called the "central system" may resist both replication and generalization by their very nature and not because of weak and underpowered experimental methods. With such phenomena, science might give us very good tools for explanation, but not for prediction (replication).

Common Sense Beliefs about the Central Self, Moral Character, and the Brain.

To assess lay beliefs about self and brain, we probed people's opinions about the central self, in relation to morality, willful control, and brain relevance. In study 1, 172 participants compared the central self to the peripheral self. The central self, construed at this abstract level, was seen as more brain-based than the peripheral self, less changeable through willful control, and yet more indicative of moral character. In study 2, 210 participants described 18 specific personality traits on 6 dimensions: centrality to self, moral relevance, willful control, brain dependence, temporal stability, and desirability. Consistent with Study 1, centrality to the self, construed at this more concrete level, was positively correlated to brain dependence. Centrality to the self was also correlated to desirability and temporal stability, but not to morality or willful control. We discuss differences and similarities between abstract (Study 1) and concrete (Study 2) levels of construal of the central self, and conclude that in contemporary American society people readily embrace the brain as the underlying substrate of who they truly are.

Multiple types of motives don't multiply the motivation of West Point cadets.

Although people often assume that multiple motives for doing something will be more powerful and effective than a single motive, research suggests that different types of motives for the same action sometimes compete. More specifically, research suggests that instrumental motives, which are extrinsic to the activities at hand, can weaken internal motives, which are intrinsic to the activities at hand. We tested whether holding both instrumental and internal motives yields negative outcomes in a field context in which various motives occur naturally and long-term educational and career outcomes are at stake. We assessed the impact of the motives of over 10,000 West Point cadets over the period of a decade on whether they would become commissioned officers, extend their officer service beyond the minimum required period, and be selected for early career promotions. For each outcome, motivation internal to military service itself predicted positive outcomes; a relationship that was negatively affected when instrumental motives were also in evidence. These results suggest that holding multiple motives damages persistence and performance in educational and occupational contexts over long periods of time.

Can patients help teach professionalism and empathy to dental students? Adding patient videos to a lecture course.

A key aspect of predoctoral dental education involves ethics/professionalism and interpersonal communications. Empathy is an integral aspect of both. This study at the Schulich School of Medicine and Dentistry, University of Western Ontario, examined predoctoral students' perspectives to determine the impact of new educational methodologies designed to integrate patients' voices into a patient management lecture course. Videos of patients describing their dental experiences were added along with classroom discussion and students' reflective journals on the topics raised. Early results indicate that students perceived this innovation enhanced the teaching of professionalism, raised their awareness of the importance of empathy, and was a well-received addition to the course.

Writing off the copayment.

Three dentists who have been involved in teaching ethics comment on a case where an associate discovers that the 40% of collections she was expecting as compensation is being reduced because of the practice in the office of routinely writing off patient copays. The commentators note legal requirements and professional codes, but generally seek alternatives that do not require that patients pay the amount agreed by insurance contracts.

A New Veil of Ignorance? Commentary on Norton and Ariely (2011).

Norton and Ariely's (2011, this issue) finding that people prefer relatively equal distributions of wealth begs for further research. It is one thing to argue, as T. Frank (2004) has, that people vote against their interests. But Norton and Ariely seem to show that people vote against their preferences. What does that even mean, and how does it happen?

Too Much of a Good Thing: The Challenge and Opportunity of the Inverted U.

Aristotle proposed that to achieve happiness and success, people should cultivate virtues at mean or intermediate levels between deficiencies and excesses. In stark contrast to this assertion that virtues have costs at high levels, a wealth of psychological research has focused on demonstrating the well-being and performance benefits of positive traits, states, and experiences. This focus has obscured the prevalence and importance of nonmonotonic inverted-U-shaped effects, whereby positive phenomena reach inflection points at which their effects turn negative. We trace the evidence for nonmonotonic effects in psychology and provide recommendations for conceptual and empirical progress. We conclude that for psychology in general and positive psychology in particular, Aristotle's idea of the mean may serve as a useful guide for developing both a descriptive and a prescriptive account of happiness and success.

The Limits of Cost-Benefit Calculation: Commentary on Bennis, Medin, & Bartels (2010).

Bennis, Medin, and Bartels (2010, this issue) correctly identify real limits to the efficacy of cost-benefit analysis in comparison to moral rules. In this commentary, I suggest that those very same limits apply to decision making in general. Cost-benefit analysis may be the best way to arrive at decisions under a set of "closed-world assumptions" like those described by Bennis et al. But those assumptions virtually never hold, and in the absence of those assumptions, cost-benefit analysis often substitutes counting for thinking.
