The nature of racial superhumanization bias.

A superhumanization bias involves attribution of qualities that are beyond human to a certain group. Waytz and colleagues reported evidence supporting this bias among White Americans wherein Black targets were perceived as more capable of possessing superhuman qualities than White targets. We sought to better understand the nature of this effect by using different response scales (forced choice vs. Likert) and instruction sets (supporting vs. not supporting existence of superhuman abilities). Results across three studies replicate the superhumanization effect and demonstrate the necessity of several key methodological features; however, under the most realistic survey conditions (i.e. allowing unbiased decisions, being truthful about the existence of such abilities), no significant superhumanization bias emerged. Additionally, in conditions with significant bias, the size of the effect was relatively small, suggesting that this bias may not be as widespread as previously believed; indeed, only a minority of participants showed superhumanization in the predicted direction. Findings support the importance of exploring how arbitrary methodological decisions change inferences about psychological phenomena in the population.

Reply to the commentaries: A radical revision of experimental social psychology is still needed.

Are the landscapes of real-world decisions adequately represented in our laboratory tasks? Are the goals and expertise of experimental participants the same as real-world decision-makers? Are we neglecting crucial forces that lead to group outcomes? Are the contingencies necessary for producing experimental demonstrations of bias present in the real world? In the target article, I argued that the answers to these questions are needed to understand whether and how laboratory research can inform real-world group disparities. Most of the commentaries defending experimental social psychology neglected to directly address these main arguments. The commentaries defending implicit bias only revealed the inadequacy of this concept for explaining group disparities. The major conclusions from the target article remain intact, suggesting that experimental social psychology must undergo major changes to contribute to our understanding of group disparities.

Attenuation of the Köhler Effect in Racially Dissimilar Partnered Exercise Reversed Using Team Identity Strategy.

The authors describe two research experiments exploring the influence of race on the Köhler motivation gain effect with exercise tasks. Experiment 1 tested whether partner racial dissimilarity affects individual performance. Experiment 2 created a team identity recategorization intervention to potentially counter the influence on performance observed in Experiment 1. White male participants were partnered with either a Black or Asian partner (Experiment 1) or with a Black partner utilizing team names and shirt colors as a team identity recategorization strategy (Experiment 2). Racially dissimilar dyads completed two sets of abdominal plank exercises with a Köhler conjunctive task paradigm (stronger partner; team performance outcome dependent upon the weaker-ability participant's performance). The results of Experiment 1 suggest attenuation of the previously successful group motivation gain effect in the racially dissimilar condition. The simple recategorization strategy utilized in Experiment 2 appeared to reverse motivation losses under conjunctive-task conditions in racially dissimilar exercise dyads.

What can experimental studies of bias tell us about real-world group disparities?

This article questions the widespread use of experimental social psychology to understand real-world group disparities. Standard experimental practice is to design studies in which participants make judgments of targets who vary only on the social categories to which they belong. This is typically done under simplified decision landscapes and with untrained decision-makers. For example, to understand racial disparities in police shootings, researchers show pictures of armed and unarmed Black and White men to undergraduates and have them press "shoot" and "don't shoot" buttons. Having demonstrated categorical bias under these conditions, researchers then use such findings to claim that real-world disparities are also due to decision-maker bias. I describe three flaws inherent in this approach, flaws which undermine any direct contribution of experimental studies to explaining group disparities. First, the decision landscapes used in experimental studies lack crucial components present in actual decisions (missing information flaw). Second, categorical effects in experimental studies are not interpreted in light of other effects on outcomes, including behavioral differences across groups (missing forces flaw). Third, there is no systematic testing of whether the contingencies required to produce experimental effects are present in real-world decisions (missing contingencies flaw). I apply this analysis to three research topics to illustrate the scope of the problem. I discuss how this research tradition has skewed our understanding of the human mind within and beyond the discipline and how results from experimental studies of bias are generally misunderstood. I conclude by arguing that the current research tradition should be abandoned.

Category salience and racial bias in weapon identification: A diffusion modeling approach.

Stereotypes linking Black Americans with guns can have life-altering outcomes, making it important to identify factors that shape such weapon identification biases and how they do so. We report 6 experiments that provide a mechanistic account of how category salience affects weapon identification bias elicited by male faces varying in race (Black, White) and age (men, boys). Behavioral analyses of error rates and response latencies revealed that, when race was salient, faces of Black versus White males (regardless of age) facilitated the classification of objects as guns versus tools. When a category other than race was salient, racial bias in behavior was reduced, though not eliminated. In Experiments 1-4, racial bias was weaker when participants attended to a social category besides race (i.e., age). In Experiments 5 and 6, racial bias was weaker when participants attended to an applicable, yet nonsubstantive category (i.e., the color of a dot on the face). Across experiments, process analyses using diffusion models revealed that, when race was salient, seeing Black versus White male faces led to an initial bias to favor the "gun" response. When a category besides race (i.e., age, dot color) was salient, racial bias in the relative start point was reduced, though not eliminated. These results suggest that the magnitude of racial bias in weapon identification may differ depending on what social category is salient. The collective findings also highlight the utility of diffusion modeling for elucidating how category salience shapes processes underlying racial biases in behavior.

Officer characteristics and racial disparities in fatal officer-involved shootings.

Despite extensive attention to racial disparities in police shootings, two problems have hindered progress on this issue. First, databases of fatal officer-involved shootings (FOIS) lack details about officers, making it difficult to test whether racial disparities vary by officer characteristics. Second, there are conflicting views on which benchmark should be used to determine racial disparities when the outcome is the rate at which members from racial groups are fatally shot. We address these issues by creating a database of FOIS that includes detailed officer information. We test racial disparities using an approach that sidesteps the benchmark debate by directly predicting the race of civilians fatally shot rather than comparing the rate at which racial groups are shot to some benchmark. We report three main findings: 1) As the proportion of Black or Hispanic officers in a FOIS increases, a person shot is more likely to be Black or Hispanic than White, a disparity explained by county demographics; 2) race-specific county-level violent crime strongly predicts the race of the civilian shot; and 3) although we find no overall evidence of anti-Black or anti-Hispanic disparities in fatal shootings, when focusing on different subtypes of shootings (e.g., unarmed shootings or "suicide by cop"), data are too uncertain to draw firm conclusions. We highlight the need to enforce federal policies that record both officer and civilian information in FOIS.

How prior information and police experience impact decisions to shoot.

Social psychologists have relied on computerized shooting tasks to test whether race influences decisions to shoot. These studies reveal that under some conditions untrained individuals shoot unarmed Black men more than unarmed White men. We modeled the decision to shoot as a sequential sampling process in which people start out with prior biases and accumulate evidence over time until a threshold is reached, prompting a decision. We used this approach to test how prior information (a proxy for police dispatch information) and police experience influence racial bias in shooting decisions. When no prior information was given, target race biased the rate at which untrained civilians accumulated evidence, leading to a greater rate of shooting Black targets. For sworn police officers, the race of the target impacted prior bias, but not evidence accumulation. Moreover, officers showed no race bias in the observed decision to shoot. For both untrained civilians and sworn police officers, prior information about a target's race was sufficient to eliminate racial bias in shooting decisions both at the process and behavioral level. These studies reveal that factors present in real-world shooting decisions (dispatch information and police experience) can moderate the role that race plays both in the underlying cognitive processes and ultimately on the observed decision. We discuss the benefits of using a dynamic cognitive model to understand the decision to shoot and the implications of these results for laboratory analogues of real-world decisions.

Registered Replication Report: Dijksterhuis and van Knippenberg (1998).

Dijksterhuis and van Knippenberg (1998) reported that participants primed with a category associated with intelligence ("professor") subsequently performed 13% better on a trivia test than participants primed with a category associated with a lack of intelligence ("soccer hooligans"). In two unpublished replications of this study designed to verify the appropriate testing procedures, Dijksterhuis, van Knippenberg, and Holland observed a smaller difference between conditions (2%-3%) as well as a gender difference: Men showed the effect (9.3% and 7.6%), but women did not (0.3% and -0.3%). The procedure used in those replications served as the basis for this multilab Registered Replication Report. A total of 40 laboratories collected data for this project, and 23 of these laboratories met all inclusion criteria. Here we report the meta-analytic results for those 23 direct replications (total N = 4,493), which tested whether performance on a 30-item general-knowledge trivia task differed between these two priming conditions (results of supplementary analyses of the data from all 40 labs, N = 6,454, are also reported). We observed no overall difference in trivia performance between participants primed with the "professor" category and those primed with the "hooligan" category (0.14%) and no moderation by gender.

How race affects evidence accumulation during the decision to shoot.

The biasing role of stereotypes is a central theme in social cognition research. For example, to understand the role of race in police officers' decisions to shoot, participants have been shown images of Black and White males and instructed to shoot only if the target is holding a gun. Findings show that Black targets are shot more frequently and more quickly than Whites. The decision to shoot has typically been modeled and understood as a signal detection process in which a sample of information is compared against a criterion, with the criterion set for Black targets being lower. We take a different approach, modeling the decision to shoot as a dynamic process in which evidence is accumulated over time until a threshold is reached. The model accounts for both the choice and response time data for both correct and incorrect decisions using a single set of parameters. Across four studies, this dynamic perspective revealed that the target's race did not create an initial bias to shoot Black targets. Instead, race impacted the rate of evidence accumulation with evidence accumulating faster to shoot for Black targets. Some participants also tended to be more cautious with Black targets, setting higher decision thresholds. Besides providing a more cohesive and richer account of the decision to shoot or not, the dynamic model suggests interventions that may address the use of race information in decisions to shoot and a means to measure their effectiveness.

Warm water and loneliness redux: rejoinder to Shalev and Bargh (2014) study 1.

Shalev and Bargh (2014) replied to our work and summarized results from 3 new studies concerning the associations between trait loneliness and showering/bathing habits. We clarify a few issues and provide a foundation for future work by conducting a meta-analysis of the relevant studies. The inclusion of new data does little to change our basic conclusions. There are no indications of strong connections between trait loneliness and showering/bathing habits. Additional studies are needed to test moderators of these associations, and to evaluate possible cross-cultural differences in the connection between loneliness and physical warmth extraction from baths and showers.

On the association between loneliness and bathing habits: nine replications of Bargh and Shalev (2012) Study 1.

Bargh and Shalev (2012) hypothesized that people use warm showers and baths to compensate for a lack of social warmth. As support for this idea, they reported results from two studies that found an association between trait loneliness and bathing habits. Given the potential practical and theoretical importance of this association, we conducted nine additional studies on this topic. Using our own bathing or showering measures and the most current version of the UCLA Loneliness Scale (Russell, 1996), we found no evidence for an association between trait loneliness and a composite index of showering or bathing habits in a combined sample of 1,153 participants from four studies. Likewise, the aggregated effect size estimate was not statistically significant using the same measures as the original studies in a combined sample of 1,920 participants from five studies. A local meta-analysis including the original studies yielded an effect size estimate for the composite that included zero in the 95% confidence interval. The current results therefore cast doubt on the idea of a strong connection between trait loneliness and personal bathing habits related to warmth.

Priming, Replication, and the Hardest Science.

Concerns have been raised recently about the replicability of behavioral priming effects, and calls have been issued to identify priming methodologies with effects that can be obtained in any context and with any population. I argue that such expectations are misguided and inconsistent with evolutionary understandings of the brain as a computational organ. Rather, we should expect priming effects to be highly sensitive to variations in experimental features and subject populations. Such variation does not make priming effects frivolous or capricious but instead can be predicted a priori. However, absent theories specifying the precise contingencies that lead to such variation, failures to replicate another researcher's findings will necessarily be ambiguous with respect to the inferences that can be made. Priming research is not yet at the stage where such theories exist, and therefore failures are uninformative at the current time. Ultimately, priming researchers themselves must provide direct replications of their own effects; researchers have been deficient in meeting this responsibility and have contributed to the current state of confusion. The recommendations issued in this article reflect concerns both with the practice of priming researchers and with the inappropriate expectations of researchers who have failed to replicate others' priming effects.

Of mice and men: what animal research can tell us about context effects on automatic responses in humans.

Automatic responses play a central role in many areas of psychology. Counter to views that such responses are relatively rigid and inflexible, a large body of research has shown that they are highly context-sensitive. Research on animal learning and animal behavior has a strong potential to provide a deeper understanding of such context effects by revealing remarkable parallels between the functional properties of automatic responses in human and nonhuman animals. These parallels involve the contextual modulation of attitude formation and change (automatic evaluation), and the role of contextual contingencies in shaping the particular action tendencies in response to a stimulus (automatic behavior). Theoretical concepts of animal research not only provide novel insights into the processes and representations underlying context effects on automatic responses in humans; they also offer new perspectives on the interface between affect, cognition, and motivation.

Effects of musicality and motivational orientation on auditory category learning: a test of a regulatory-fit hypothesis.

Two experiments investigated the effects of musicality and motivational orientation on auditory category learning. In both experiments, participants learned to classify tone stimuli that varied in frequency and duration according to an initially unknown disjunctive rule; feedback involved gaining points for correct responses (a gains reward structure) or losing points for incorrect responses (a losses reward structure). For Experiment 1, participants were told at the start that musicians typically outperform nonmusicians on the task, and then they were asked to identify themselves as either a "musician" or a "nonmusician." For Experiment 2, participants were given either a promotion focus prime (a performance-based opportunity to gain entry into a raffle) or a prevention focus prime (a performance-based criterion that needed to be maintained to avoid losing an entry into a raffle) at the start of the experiment. Consistent with a regulatory-fit hypothesis, self-identified musicians and promotion-primed participants given a gains reward structure made more correct tone classifications and were more likely to discover the optimal disjunctive rule than were musicians and promotion-primed participants experiencing losses. Reward structure (gains vs. losses) had inconsistent effects on the performance of nonmusicians, and a weaker regulatory-fit effect was found for the prevention focus prime. Overall, the findings from this study demonstrate a regulatory-fit effect in the domain of auditory category learning and show that motivational orientation may contribute to musician performance advantages in auditory perception.

The ecology of automaticity. How situational contingencies shape action semantics and social behavior.

What is the role of ecology in automatic cognitive processes and social behavior? Our motivated-preparation account posits that priming a social category readies the individual for adaptive behavioral responses to that category-responses that take into account the physical environment. We present the first evidence showing that the cognitive responses (Study 1) and the behavioral responses (Studies 2a and 2b) automatically elicited by a social-category prime differ depending on a person's physical surroundings. Specifically, after priming with pictures of Black men (a threatening out-group), participants responded with either aggressive behavior (fight) or distancing behavior (flight), depending on what action was allowed by the situation. For example, when participants were seated in an enclosed booth (no distancing behavior possible) during priming, they showed increased accessibility of fight-related action semantics; however, when seated in an open field (distancing behavior possible), they showed increased accessibility of flight-related action semantics. These findings suggest that an understanding of automaticity must consider its situated nature.

Increasing or decreasing interest in activities: the role of regulatory fit.

What makes people's interest in doing an activity increase or decrease? Regulatory fit theory (E. T. Higgins, 2000) provides a new perspective on this classic issue by emphasizing the relation between people's activity orientation, such as thinking of an activity as fun, and the manner of activity engagement that the surrounding situation supports. These situational factors include whether a reward for good performance, expected (Study 1) or unexpected (Study 2), is experienced as enjoyable or as serious and whether the free-choice period that measures interest in the activity is experienced as enjoyable or as serious (Study 3). Studies 1-3 found that participants were more likely to do a fun activity again when these situational factors supported a manner of doing the activity that fit the fun orientation-a reward or free-choice period framed as enjoyable. This effect was not because interest in doing an activity again is simply greater in an enjoyable than a serious surrounding situation because it did not occur, and even reversed, when the activity orientation was important rather than fun, where now a serious manner of engagement provides the fit (Study 4a and 4b).

Incidental experiences of regulatory fit and the processing of persuasive appeals.

This article examines how the subjective experiences of "feeling right" from regulatory fit and of "feeling wrong" from regulatory non-fit influence the way people process persuasive messages. Across three studies, incidental experiences of regulatory fit increased reliance on source expertise and decreased resistance to counterpersuasion, whereas incidental experiences of regulatory non-fit increased reliance on argument strength and increased resistance to counterpersuasion. These results suggest that incidental fit and non-fit experiences can produce, respectively, more superficial or more thorough processing of persuasive messages. The mechanisms underlying these effects, and the conditions under which they should and should not be expected, are discussed.
