Taboos and Self-Censorship Among U.S. Psychology Professors.

We identify points of conflict and consensus regarding (a) controversial empirical claims and (b) normative preferences for how controversial scholarship-and scholars-should be treated. In 2021, we conducted qualitative interviews (n = 41) to generate a quantitative survey (N = 470) of U.S. psychology professors' beliefs and values. Professors strongly disagreed on the truth status of 10 candidate taboo conclusions: For each conclusion, some professors reported 100% certainty in its veracity and others 100% certainty in its falsehood. Professors more confident in the truth of the taboo conclusions reported more self-censorship, a pattern that could bias perceived scientific consensus regarding the inaccuracy of controversial conclusions. Almost all professors worried about social sanctions if they were to express their own empirical beliefs. Tenured professors reported as much self-censorship and as much fear of consequences as untenured professors, including fear of getting fired. Most professors opposed suppressing scholarship and punishing peers on the basis of moral concerns about research conclusions and reported contempt for peers who petition to retract papers on moral grounds. Younger, more left-leaning, and female faculty were generally more opposed to controversial scholarship. These results do not resolve empirical or normative disagreements among psychology professors, but they may provide an empirical context for their discussion.

Multi-Site Replications in Social Psychology: Reflections, Implications, and Future Directions.

Social psychology findings have fared poorly in multi-site replication attempts. This article considers and evaluates multiple factors that may contribute to such failures, other than the "crisis" assumption that most of the field's published research is so badly flawed that it should be dismissed wholesale. Low engagement by participants may reduce replicability of some findings (while not affecting certain others). Incentives differ between original researchers and replicators. If multi-site replications are indeed biased toward failure, this may have a damaging effect on the field's ability to build correct theories.

A Review of Multisite Replication Projects in Social Psychology: Is It Viable to Sustain Any Confidence in Social Psychology's Knowledge Base?

Multisite (multilab/many-lab) replications have emerged as a popular way of verifying prior research findings, but their record in social psychology has prompted distrust of the field and a sense of crisis. We review all 36 multisite social-psychology replications (plus three articles reporting multiple ministudies). We start by assuming that both the original and the multisite replications were conducted in honest and diligent fashion, despite often yielding different conclusions. Four of the 36 (11%) were clearly successful in terms of providing significant support for the original hypothesis, and five others (14%) had mixed results. The remaining 27 (75%) were failures. Multiple explanations for the generally poor record of replications are considered, including the possibility that the original hypothesis was wrong; operational failure; low engagement of participants; and bias toward failure. The relevant evidence is assessed as well. There was evidence for each of the possibilities listed above, with low engagement emerging as a widespread problem (reflected in high rates of discarded data and weak manipulation checks). The few procedures with actual interpersonal interaction fared much better than others. We discuss implications in relation to manipulation checks, effect sizes, and impact on the field and offer recommendations for improving future multisite projects.

Psychological and behavioral implications of self-protection and self-enhancement.

Self-protection can have psychological and behavioral implications. We contrast them with the implications of a self-enhancement strategy. Both self-enhancement and self-protection have costs and benefits as survival strategies, and we identify some of the emotional, cognitive, and behavioral tradeoffs associated with the differential preferences for each strategy. New analyses on a large existing data set confirm the target article's hypothesis that women are more attuned than men to potential negative consequences of innovations.

What You Don't Know Can Hurt You: Uncertainty Impairs Executive Function.

Three studies demonstrated that situational uncertainty impairs executive function on subsequent unrelated tasks. Participants were randomly assigned to either uncertain situations (not knowing whether they would have to give a speech later, Studies 1-2; uncertain about how to complete a task, Study 3) or control conditions. Uncertainty caused poor performance on tasks requiring executive function that were unrelated to the uncertainty manipulation. Uncertainty impaired performance even more than certainty of negative outcomes (might vs. definitely will have to make a speech). A meta-analysis of the experimental studies in this package found that the effect is small and reliable. One potential explanation for this effect of uncertainty on executive function is that uncertainty is a cue for conserving effort.

Life is uncertain, eat dessert first: Uncertainty causes controlled and unemotional eaters to consume more sweets.

Sometimes even dieters with the best self-control overindulge. Uncertain situations may undermine the self-control of even well-controlled eaters. This study was designed to test the hypothesis that uncertainty increases unhealthy snacking. Participants were either told that they would be giving a speech, that they would be listening to a speech, or that they would find out later whether they were to give a speech or not. Among participants who typically reported good control over their eating or scored low on emotional eating, participants who were uncertain about whether they would be giving a speech ate more candy than participants who expected to not have to give a speech and even those who expected to have to give a speech. Participants who reported poor control over their eating or scored high on emotional eating did not eat significantly more when uncertain. These findings suggest that, for people who are typically able to control their eating, uncertainty increases snacking more than certainty of a negative outcome.

Personal Conflict Impairs Performance on an Unrelated Self-Control Task: Lingering Costs of Uncertainty and Conflict.

People have the ability to make important choices in their lives, but deliberating about these choices can have costs. The present study was designed to test the hypothesis that writing about conflicted personal goals and values (conflict condition) would impair self-control on an unrelated subsequent task as compared to writing about clear personal goals and values (clarity condition). Personal conflict activates the behavioral inhibition system (BIS; Hirsh, Mar, & Peterson, 2012), which may make it harder for participants to successfully execute self-control. In this large (N=337), pre-registered study participants in the conflict condition performed worse on anagrams than participants in the clarity condition, and the effect of condition on anagram performance was mediated by a subjective uncertainty measure of BIS activation. This suggests that BIS activation leads to poor self-control. Moreover, given that conflict is inherent in the exercise of self-control, results point to BIS activation as a mechanism for why initial acts of self-control impair self-control on subsequent, unrelated tasks.

The Strength Model of Self-Regulation: Conclusions From the Second Decade of Willpower Research.

The strength model of self-regulation uses a muscle analogy to explain patterns of ego depletion, conservation of willpower, and improved performance after frequent exercise. Our 2007 overview of the literature has been well cited, presumably because of the phenomenon's importance to theories of selfhood and a wide assortment of applied contexts, including problem behaviors. Some researchers have put forward rival theoretical accounts, and others have questioned the existence of the phenomenon. The weight of evidence continues to support the usefulness of the strength model, albeit amid continuing updates and revisions.

Trait self-esteem and claimed self-handicapping motives in sports situations.

We examined the relationship between physical self-esteem and claimed self-handicapping among athletes by taking motives into consideration. In Study 1, 99 athletes were asked to report their tendency to engage in claimed self-handicapping for self-protective and self-enhancement motives (trait measures). Low self-esteem athletes reported a higher tendency to engage in claimed self-handicapping for these two motives compared with high self-esteem athletes. Neither low nor high self-esteem athletes reported a preference for one motive over the other. In Study 2, 107 athletes participated in a test that was ostensibly designed to assess high physical abilities - and thus to encourage self-handicapping for self-enhancement motives (success-meaningful condition) - or to assess low physical abilities, and thus to encourage self-handicapping for self-protective motives (failure-meaningful condition). Before starting the test, athletes were given the opportunity to claim handicaps that could impair their performance. Low self-esteem athletes claimed more handicaps than high self-esteem athletes in both conditions. Findings suggest that low physical self-esteem athletes engage more in claimed handicapping regardless of motives, relative to high physical self-esteem athletes.

Acetaminophen reduces social pain: behavioral and neural evidence.

Pain, whether caused by physical injury or social rejection, is an inevitable part of life. These two types of pain-physical and social-may rely on some of the same behavioral and neural mechanisms that register pain-related affect. To the extent that these pain processes overlap, acetaminophen, a physical pain suppressant that acts through central (rather than peripheral) neural mechanisms, may also reduce behavioral and neural responses to social rejection. In two experiments, participants took acetaminophen or placebo daily for 3 weeks. Doses of acetaminophen reduced reports of social pain on a daily basis (Experiment 1). We used functional magnetic resonance imaging to measure participants' brain activity (Experiment 2), and found that acetaminophen reduced neural responses to social rejection in brain regions previously associated with distress caused by social pain and the affective component of physical pain (dorsal anterior cingulate cortex, anterior insula). Thus, acetaminophen reduces behavioral and neural responses associated with the pain of social rejection, demonstrating substantial overlap between social and physical pain.

Making choices impairs subsequent self-control: a limited-resource account of decision making, self-regulation, and active initiative.

The current research tested the hypothesis that making many choices impairs subsequent self-control. Drawing from a limited-resource model of self-regulation and executive function, the authors hypothesized that decision making depletes the same resource used for self-control and active responding. In 4 laboratory studies, some participants made choices among consumer goods or college course options, whereas others thought about the same options without making choices. Making choices led to reduced self-control (i.e., less physical stamina, reduced persistence in the face of failure, more procrastination, and less quality and quantity of arithmetic calculations). A field study then found that reduced self-control was predicted by shoppers' self-reported degree of previous active decision making. Further studies suggested that choosing is more depleting than merely deliberating and forming preferences about options and more depleting than implementing choices made by someone else and that anticipating the choice task as enjoyable can reduce the depleting effect for the first choices but not for many choices.

Salivary cortisol in response to acute social rejection and acceptance by peers.

Past research indicates that social rejection predicts a wide range of psychological problems (e.g., depression), but laboratory studies examining self-reports of negative affect after social rejection have reported inconsistent results. Salivary cortisol was measured before and after a social rejection/acceptance manipulation for objective assessment of psychological distress subsequent to peer rejection. Rejected participants were predicted to show significantly greater salivary cortisol than accepted or control participants. The present research also examined several factors that may moderate the relationship between acute rejection and cortisol. As predicted, rejected participants exhibited significantly higher cortisol than accepted or control participants. Defensiveness moderated the relationship between rejection and cortisol; highly defensive rejected participants showed significantly lower cortisol than less defensive rejected participants after peer rejection. Results indicate that social rejection causes psychological distress, but highly defensive individuals appear to be less susceptible than less defensive individuals to increases in salivary cortisol after acute social rejection.

Self-control relies on glucose as a limited energy source: willpower is more than a metaphor.

The present work suggests that self-control relies on glucose as a limited energy source. Laboratory tests of self-control (i.e., the Stroop task, thought suppression, emotion regulation, attention control) and of social behaviors (i.e., helping behavior, coping with thoughts of death, stifling prejudice during an interracial interaction) showed that (a) acts of self-control reduced blood glucose levels, (b) low levels of blood glucose after an initial self-control task predicted poor performance on a subsequent self-control task, and (c) initial acts of self-control impaired performance on subsequent self-control tasks, but consuming a glucose drink eliminated these impairments. Self-control requires a certain amount of glucose to operate unimpaired. A single act of self-control causes glucose to drop below optimal levels, thereby impairing subsequent attempts at self-control.

Who's in Charge Here?: Group Leaders Do Lend Help in Emergencies.

Past work has shown that bystanders often fail to help a victim in an emergency, because responsibility for helping diffuses over all the bystanders there. In the present experiment, subjects were exposed to a simulated emergency (a choking fit) that occurred in the course of a structured group interaction. Subjects who had been designated as subordinate group members for the experimental task generally failed to come to the victim's aid, consistent with past findings. Subjects who had been designated as group leaders were quite likely to intervene in the emergency, however, even though responding to the emergency meant violating the experimental instructions and thus nullifying their leadership role. The implication is that a leadership role functions as a generalized responsibility cue; so group leaders do not undergo diffusion of responsibility as much as subordinate group members.
