Disentangling the nuances of diversity ideologies

Objectives

Minoritized racial groups typically report greater psychological engagement and safety in contexts that endorse multiculturalism rather than colorblindness. However, organizational statements often contain multiple (sub)components of these ideologies. This research broadens our understanding of diversity ideologies in the real-world by: (1) mapping out the content of real-world organizational diversity ideologies, (2) identifying how different components tend to cluster in real-world statements, and (3) presenting these statements to minoritized group members (Study 2) to test how these individual components and clusters are perceived (e.g., company interest, value fit).

Methods

100 US university statements and 248 Fortune 500 company statements were content coded, and 237 racially minoritized participants (Mage = 28.1; 51.5% female; 48.5% male) rated their psychological perceptions of the Fortune 500 statements.

Results

While universities most commonly frame diversity ideologies in terms of value-in-equality, companies focus more on value-in-individual differences. Diversity rationales also differ between organizations, with universities focusing on the moral and business cases almost equally, but companies focusing on the business case substantially more. Results also offered preliminary evidence that minoritized racial group members reported a greater sense of their values fitting those of the organization when considering organizations that valued individual and group differences.

Conclusion

These are some of the first studies to provide a nuanced examination of the components and clusters of diversity ideologies that real-world organizations are using, ultimately with implications for how we move forward in studying diversity ideologies (to better reflect reality) and redesigning them to encourage more diverse and inclusive organizations.

Rapid measurement and machine learning classification of color vision deficiency

Color vision deficiencies (CVDs) indicate potential genetic variations and can be important biomarkers of acquired impairment in many neuro-ophthalmic diseases. However, CVDs are typically measured with insensitive or inefficient tools that are designed to classify dichromacy subtypes rather than track changes in sensitivity. We introduce FInD (Foraging Interactive D-prime), a novel computer-based, generalizable, rapid, self-administered vision assessment tool and applied it to color vision testing. This signal detection theory-based adaptive paradigm computes test stimulus intensity from d-prime analysis. Stimuli were chromatic gaussian blobs in dynamic luminance noise, and participants clicked on cells that contain chromatic blobs (detection) or blob pairs of differing colors (discrimination). Sensitivity and repeatability of FInD Color tasks were compared against HRR, FM100 hue tests in 19 color-normal and 18 color-atypical, age-matched observers. Rayleigh color match was completed as well. Detection and Discrimination thresholds were higher for atypical observers than for typical observers, with selective threshold elevations corresponding to unique CVD types. Classifications of CVD type and severity via unsupervised machine learning confirmed functional subtypes. FInD tasks reliably detect CVD and may serve as valuable tools in basic and clinical color vision science.

More Similarity if Different, More Difference if Similar: Assimilation, Colorblindness, Multiculturalism, Polyculturalism, and Generalized and Specific Negative Intergroup Bias

The creation of a social climate where all ethnic groups can harmoniously coexist is a central challenge for many countries today. Should we emphasize similarities and common ground or, conversely, recognize that there are important differences between groups? The current study examined relations between diversity ideologies (assimilation, colorblindness, multiculturalism, polyculturalism) and generalized and specific intergroup bias (against Chechens, Belarusians, Uzbeks, Chinese, and Jews and Muslims) among ethnic Russians (N = 701). In Study 1, colorblindness (ignoring differences) and polyculturalism (emphasizing interconnectivity) were associated with lower generalized intergroup bias and lower bias against Chechens, Uzbeks, and Chinese, but not Belarusians. Bias against Belarusians was lower among those who endorsed multiculturalism (emphasizing differences). In Study 2, multiculturalism was associated with higher implicit bias when the target was a Chechen but in general more proximal variables (positive or negative contact experience and perceived group similarity) were more robust predictors of intergroup bias than diversity ideologies. In Study 3, colorblindness and polyculturalism were related to lower levels of fearful attitudes against Muslims. Colorblindness was also associated with lower levels of Antisemitism in contrast to multiculturalism that had an opposite association. We place these results in the context of cultural distance and existing cultural stereotypes about different groups among the majority of Russians. The strengths and weaknesses of each diversity ideology for the mainstream cultural group are discussed. The results of the current study suggest that the most fruitful strategy for mainstream cultural groups for maintaining harmonious intergroup relations in diverse societies might be that of optimal distinctiveness.

Multiculturalism and Colorblindness as Threats to the Self: A Framework for Understanding Dominant and Non-Dominant Group Members' Responses to Interethnic Ideologies

Both multiculturalism (which involves recognizing and appreciating differences) and racial/ethnic colorblindness (which can involve emphasizing similarities or individual characteristics) are intended to promote intergroup harmony. Nevertheless, these ideologies can backfire when salient. Although this work has sometimes been interpreted to suggest that dominant group members may perceive salient multiculturalism, and non-dominant group members may perceive salient colorblindness, as threatening, it is unclear what about these interethnic ideologies poses a threat and why. The present article draws upon theories of the self-concept to introduce a framework of Multiculturalism and Colorblindness as Threats to the Self. Specifically, it is proposed that multiculturalism (colorblindness) is potentially threatening to dominant (non-dominant) group members' collective, relational, and personal selves. Dispositional and contextual variables that may moderate perceptions of threat among members of dominant and non-dominant groups, alternative interethnic ideologies to multiculturalism and colorblindness, and potential future research directions are discussed.

A Meta-Analysis of Wearable Contact Lenses for Medical Applications: Role of Electrospun Fiber for Drug Delivery

In recent years, wearable contact lenses for medical applications have attracted significant attention, as they enable continuous real-time recording of physiological information via active and noninvasive measurements. These devices play a vital role in continuous monitoring of intraocular pressure (IOP), noninvasive glucose monitoring in diabetes patients, drug delivery for the treatment of ocular illnesses, and colorblindness treatment. In specific, this class of medical devices is rapidly advancing in the area of drug loading and ocular drug release through incorporation of electrospun fibers. The electrospun fiber matrices offer a high surface area, controlled morphology, wettability, biocompatibility, and tunable porosity, which are highly desirable for controlled drug release. This article provides an overview of the advances of contact lens devices in medical applications with a focus on four main applications of these soft wearable devices: (i) IOP measurement and monitoring, (ii) glucose detection, (iii) ocular drug delivery, and (iv) colorblindness treatment. For each category and application, significant challenges and shortcomings of the current devices are thoroughly discussed, and new areas of opportunity are suggested. We also emphasize the role of electrospun fibers, their fabrication methods along with their characteristics, and the integration of diverse fiber types within the structure of the wearable contact lenses for efficient drug loading, in addition to controlled and sustained drug release. This review article also presents relevant statistics on the evolution of medical contact lenses over the last two decades, their strengths, and the future avenues for making the essential transition from clinical trials to real-world applications.

Conversations about race in Black and White US families: Before and after George Floyd's death

In the United States, Black households and White households have very different conversations about race. After the death of George Floyd, Black parents were even more likely to have such conversations with their children and to prepare their children to experience racial bias than they were before Floyd’s death. White parents were less likely to talk about being White and more likely to socialize their children toward colorblindness. In addition, White parents remained relatively unconcerned that their children may experience or perpetrate racial bias.

Research has shown that Black parents are more likely than White parents to have conversations about race with their children, but few studies have directly compared the frequency and content of these conversations and how they change in response to national events. Here we examine such conversations in the United States before and after the killing of George Floyd. Black parents had conversations more often than White parents, and they had more frequent conversations post-Floyd. White parents remained mostly unchanged and, if anything, were less likely to talk about being White and more likely to send colorblind messages. Black parents were also more worried than White parents—both that their children would experience racial bias and that their children would perpetrate racial bias, a finding that held both pre- and post-Floyd. Thus, even in the midst of a national moment on race, White parents remained relatively silent and unconcerned about the topic.

Intermixing the OPN1LW and OPN1MW Genes Disrupts the Exonic Splicing Code Causing an Array of Vision Disorders

Light absorption by photopigment molecules expressed in the photoreceptors in the retina is the first step in seeing. Two types of photoreceptors in the human retina are responsible for image formation: rods, and cones. Except at very low light levels when rods are active, all vision is based on cones. Cones mediate high acuity vision and color vision. Furthermore, they are critically important in the visual feedback mechanism that regulates refractive development of the eye during childhood. The human retina contains a mosaic of three cone types, short-wavelength (S), long-wavelength (L), and middle-wavelength (M) sensitive; however, the vast majority (~94%) are L and M cones. The OPN1LW and OPN1MW genes, located on the X-chromosome at Xq28, encode the protein component of the light-sensitive photopigments expressed in the L and M cones. Diverse haplotypes of exon 3 of the OPN1LW and OPN1MW genes arose thru unequal recombination mechanisms that have intermixed the genes. A subset of the haplotypes causes exon 3- skipping during pre-messenger RNA splicing and are associated with vision disorders. Here, we review the mechanism by which splicing defects in these genes cause vision disorders.

Harm as a Necessary Component of the Concept of Medical Disorder: Reply to Muckler and Taylor

Wakefield's harmful dysfunction analysis asserts that the concept of medical disorder includes a naturalistic component of dysfunction (failure of biologically designed functioning) and a value (harm) component, both of which are required for disorder attributions. Muckler and Taylor, defending a purely naturalist, value-free understanding of disorder, argue that harm is not necessary for disorder. They provide three examples of dysfunctions that, they claim, are considered disorders but are entirely harmless: mild mononucleosis, cowpox that prevents smallpox, and minor perceptual deficits. They also reject the proposal that dysfunctions need only be typically harmful to qualify as disorders. We argue that the proposed counterexamples are, in fact, considered harmful; thus, they fail to disconfirm the harm requirement: incapacity for exertion is inherently harmful, whether or not exertion occurs, cowpox is directly harmful irrespective of indirect benefits, and colorblindness and anosmia are considered harmful by those who consider them disorders. We also defend the typicality qualifier as viably addressing some apparently harmless disorders and argue that a dysfunction's harmfulness is best understood in dispositional terms.

Exposure to Biracial Faces Reduces Colorblindness

Across six studies, we demonstrate that exposure to biracial individuals significantly reduces endorsement of colorblindness as a racial ideology among White individuals. Real-world exposure to biracial individuals predicts lower levels of colorblindness compared with White and Black exposure (Study 1). Brief manipulated exposure to images of biracial faces reduces colorblindness compared with exposure to White faces, Black faces, a set of diverse monoracial faces, or abstract images (Studies 2-5). In addition, these effects occur only when a biracial label is paired with the face rather than resulting from the novelty of the mixed-race faces themselves (Study 4). Finally, we show that the shift in White participants' colorblindness attitudes is driven by social tuning, based on participants' expectations that biracial individuals are lower in colorblindness than monoracial individuals (Studies 5-6). These studies suggest that the multiracial population's increasing size and visibility has the potential to positively shift racial attitudes.

When Societal Norms and Social Identity Collide: the Race Talk Dilemma for Racial Minority Children

Racial minorities face a unique "race talk" dilemma in contemporary American society: their racial background is often integral to their identity and how others perceive them, yet talk of race is taboo. This dilemma highlights the conflict between two fundamental social processes: social identity development and social norm adherence. To examine how, and with what costs, this dilemma is resolved, 9-12-year-old Latino, Asian, Black, and White children (n=108) completed a photo identification task in which acknowledging racial difference is beneficial to performance. Results indicate minority children are just as likely to avoid race as White children, and such avoidance exacted a cost to performance and nonverbal comfort. Results suggest that teachers are particularly important social referents for instilling norms regarding race. Norms that equate colorblindness with socially appropriate behavior appear more broadly influential than previously thought, stifling talk of race even among those for whom it may be most meaningful.
