Learning when not to share
This article examines the ethical complexities of research data sharing through Reese's concept of ‘curtains’ and Tuck and Yang's notion of ‘refusal’, with reflexivity serving as the guiding methodology. It explores the tensions between transparency and the protection of intimate, sacred, or culturally sensitive knowledge, particularly within specific communities. Through a series of vignettes grounded in lived experiences, the authors illustrate…
Perpetual Projects of Potential
This literature review interrogates the genealogy of questions posed about Black men and boys in Urban Education from 1965 to 2025, tracing how policy eras have delimited their discursive framing within educational research. Drawing on Goldberg's (1993) racial knowledg e and Wynter's (1995) subjective understanding , we employ a Foucauldian genealogical analysis to examine four policy periods—from the Moynihan Report to George Floyd's racial reck…
Beyond the Problematique
Individuals recently abstinent from methamphetamine show selective cognitive and behavioral differences when compared to age-matched controls
These findings suggest that methamphetamine use disorder is associated with specific cognitive and behavioral abnormalities. Targeting these constructs in treatment may improve outcomes for individuals recovering from MUD
Shame, Guilt and Psychedelic Experience
The classic psychedelic psilocybin has attracted special interest across clinical and non-clinical settings as a potential tool for mental health. Despite increasing attention to challenging psychedelic experiences, few studies have explored the relevance of shame-related processes with psychedelic use. This prospective, longitudinal study involved sequential, automated, web-based surveys that collected data from 679 adults planning to use psiloc…
Land Titling, Race, and Political Violence
Under what conditions do reforms prompt violent counterreform? Reform threatens elite interests in structurally unequal societies, prompting elites to use their power to counter reform. Although the existing literature demonstrates the material logic of counterreform, the authors build on critical race theory to argue that elites are more likely to target reforms meant for racially marginalized beneficiaries. The authors test this argument using …
Psychedelic and MDMA-Related Adverse Effects—A Call for Action
This Viewpoint discusses the need to better understand potential risks associated with psychedelic and 3,4-methylenedioxymethamphetamine (MDMA) use to ensure safe and ethical practice and identifies 4 key research goals
A doctorate doesn’t make you a “Doc”
Purpose This study aims to stimulate scholarly attention and practical application pertaining to individuals recognized as “Docs.” Through conducting a comprehensive analysis and acquiring a profound understanding of its many connotations, the objective is to shift attitudes and approaches concerning those who are seen to possess knowledge and value within society. Design/methodology/approach For this study, culturally relevant pedagogies were us…
You’re nobody until somebody kills you
In this article, we utilized Charles Mills' racial contract and Derrick Bell's interest-convergence as theories to anchor our understanding of the exploitation of Black death to bolster institutional DEI efforts. We argue that mainstream forms of sociopolitical progress have emerged in the wake of Black death. In essence, Black death precedes and is necessary for the enactment – often performatively – of institutional social justice efforts. Acco…
Black Male Brilliance as (Ill)Legible
In this study, we examine how race and racism impact the schooling of African American males by analyzing the first-person perspective of hip-hop superstar, Nasir “Nas” Jones. We selected Nas due to his unique yet prevalent educational trajectory and perspectives. Critical race theory is employed as a framework as well as notions of Sankofa methodology and literary analysis to investigate his music, documentaries, and an open letter whereby he cr…
Validation of the Sexual Discounting Task for Use in Adolescents
Reducing Racial Asymmetries in the Survey Overestimation of Voter Turnout
Research has consistently demonstrated that Black respondents are more likely than their White counterparts to overstate their plans or previous decisions to vote. We propose that by using a single question regarding turnout intention and candidate preference (rather than the typical approach of using two separate questions), survey researchers can reduce these racial asymmetries. The reason, we suggest, is that doing so encourages Black responde…
The 'absent Black father' metaphor
In this paper, we utilize the concepts of racial knowledge and subjective understanding to demonstrate how the metaphor of surrogacy encodes a racialized discourse via the epistemic authority of social science research. Taken together, we demonstrate how the pervasive use of surrogacy as a metaphor reflects the subjective understanding of Black male teachers produced through the racial knowledge of social science discourse. We argue that the meta…
Naturalistic psilocybin use is associated with persisting improvements in mental health and wellbeing
Results from this study, the largest prospective survey of naturalistic psilocybin use to date, support the potential for psilocybin to produce lasting improvements in mental health symptoms and general wellbeing
Centering Black Perspectives Within the Social Studies Curriculum
One justification given by social studies teachers for avoiding teaching or incorporating race into their lessons is the absence of race from textbooks. Given that textbooks continue to play a significant role in social studies instruction, the authors analyzed how Dr. Carter Godwin Woodson, a Black scholar of the early twentieth century, accounted for race in two of the textbooks he wrote for K–12 teachers. In this essay, we used the principles …
Introducing Curricular and Pedagogical Resuscitation (CPR)
Social studies has been lagging in the race to gain classroom instructional time due to the impact of high-stakes testing in urban schools. Furthermore, social studies can be particularly uninteresting to Black students whose diverse sociocultural histories and perspectives remain diminished or absent. Therefore, this paper advances curricular and pedagogical resuscitation (CPR) as a renewed and continuing quest to properly address and privilege …
Delay Discounting and Sexual Decision-Making
Dynamics of Polarizing Rhetoric in Congressional Tweets
Affective polarization is pervasive in modern US politics, and can be intensified by strategic messaging from members of Congress. But there are gaps in our knowledge of the dynamics of polarizing appeals from elected representatives on social media. We explore the usage of polarizing rhetoric by members of Congress on Twitter using the 4.9 million tweets sent by members of Congress from 2009 to 2020, coded for the presence of polarizing rhetoric…
“But there is a God”
This study set out to gain a deeper understanding of how early childhood students, specifically Black boys in first and second grade, would respond to the teaching of historical figures and events traditionally omitted from classrooms. Contrary to general assumptions, these students were able to astutely contribute to classroom lessons, discussions, and interviews about Nat Turner, an enslaved Black American, who led a rebellion in 1831. Employin…
(Un)Natural Saviors and Motivators
This article explores how Black male teachers in Hollywood films continue to be encoded with meanings derived from deficit social science discourse generated through a white-controlled epistemic order. Drawing from the framework of critical public pedagogy and utilizing the critical visual cultural tradition, we contend that the representation of Black male teachers on film is rooted in longstanding conceptual narratives of Black men and boys. Fi…

Attention-Deficit/Hyperactivity Disorder Symptoms Are Associated with Greater Delay Discounting of Condom-Protected Sex and Money
The Influence of Episodic Future Thinking and Graphic Warning Labels on Delay Discounting and Cigarette Demand
Delay discounting and operant demand are two behavioral economic constructs that tend to covary, by degree, with cigarette smoking status. Given historically robust associations between adverse health outcomes of smoking, a strong preference for immediate reinforcement (measured with delay discounting), and excessive motivation to smoke cigarettes (measured with operant demand), researchers have made numerous attempts to attenuate the extent to w…
Classic psychedelics in the treatment of substance use disorder
Persisting Reductions in Cannabis, Opioid, and Stimulant Misuse After Naturalistic Psychedelic Use
While these cross-sectional and self-report methods cannot determine whether psychedelics caused changes in drug use, results suggest the potential that psychedelics cause reductions in problematic substance use, and support additional clinical research on psychedelic-assisted treatment for SUD

Factor Analysis of the Mystical Experience Questionnaire
A large body of historical evidence describes the use of hallucinogenic compounds, such as psilocybin mushrooms, for religious purposes. But few scientific studies have attempted to measure or characterize hallucinogen-occasioned spiritual experiences. The present study examined the factor structure of the Mystical Experience Questionnaire (MEQ), a self-report measure that has been used to assess the effects of hallucinogens in laboratory studies…
Electoral Discrimination
Under what conditions do elections produce racially discriminatory outcomes? This article proposes electoral discrimination as an electoral mechanism for racial marginalization in indigenous and Afro-descendant Latin America. Electoral discrimination occurs when voters are mobilized under differential terms of electoral inclusion based on their observable characteristics. Using the 2010–2014 rounds of the AmericasBarometer and a conjoint experime…
Trump, Kaepernick, and MLK as “maybe citizens”
What it means to be a citizen for groups such as children and African Americans remains a contested, abstract, and evasive concept. This article seeks to gain a greater understanding of citizenship education by injecting the voices of young Black male students who are talked to and talked about but rarely asked to contribute to citizenship discourse. What emerged from these first- and second-grade students is the framework of “maybe citizens.” Th…

When the Mirage Fades
Private high schools are often viewed as bastions of scholastic and social opportunities, but the cost of tuition has rendered these sites predominantly white and more segregated than public schools. However, with the ability to recruit, Black boys have become prime targets of predominantly white private Catholic high schools seeking promising student-athletes. As a result, the population of Black boys at these schools are composed almost entirel…

The Hotel Room Purchase Task
Remember the titans
The intent of this article is to present four historical physical education teacher educators as role models for intellectuals in academia and in particular, Black scholars in teacher education. Utilizing the concepts of archetype and critical race currere, we frame the lifeworks of E.B. Henderson, Anita J. Turner, LeRoy T. Walker, and Lavonia Allison as a curriculum for modern scholars
Within‐subject Comparison of Real and Hypothetical Money Rewards in Delay Discounting
A within‐subject design, using human participants, compared delay discounting functions for real and hypothetical money rewards. Both real and hypothetical rewards were studied across a range that included $10 to $250. For 5 of the 6 participants, no systematic difference in discount rate was observed in response to real and hypothetical choices, suggesting that hypothetical rewards may often serve as a valid proxy for real rewards in delay disco…
Delay discounting in current and never-before cigarette smokers
Research has found that nicotine-dependent individuals delay discount monetary gains at a higher rate than matched controls. Delay discount rates, however, have also been found to vary across within-subject variables such as the magnitude of the outcome (e.g., 10 dollars or 1,000 dollars), whether the outcome constitutes a gain or a loss, and the commodity being evaluated (e.g., money or health). The present study comprehensively investigated the…
An algorithm for identifying nonsystematic delay-discounting data.
Several [corrected] discounting studies have use the R2 measure to identify data [corrected] with poor fits to a mathematical discounting model as nonsystematic data to be eliminated [corrected] Data from three previous delay-discounting studies (six separate groups, with a total of 161 individuals) were used to demonstrate why using R2 to assess the fits of discounting data is problematic. A significant, positive correlation between discounting …
Mystical experiences occasioned by the hallucinogen psilocybin lead to increases in the personality domain of openness
A large body of evidence, including longitudinal analyses of personality change, suggests that core personality traits are predominantly stable after age 30. To our knowledge, no study has demonstrated changes in personality in healthy adults after an experimentally manipulated discrete event. Intriguingly, double-blind controlled studies have shown that the classic hallucinogen psilocybin occasions personally and spiritually significant mystical…
Psilocybin occasioned mystical-type experiences
Factor Analysis of the Mystical Experience Questionnaire
A large body of historical evidence describes the use of hallucinogenic compounds, such as psilocybin mushrooms, for religious purposes. But few scientific studies have attempted to measure or characterize hallucinogen-occasioned spiritual experiences. The present study examined the factor structure of the Mystical Experience Questionnaire (MEQ), a self-report measure that has been used to assess the effects of hallucinogens in laboratory studies…
Pilot study of the 5-HT 2A R agonist psilocybin in the treatment of tobacco addiction
Despite suggestive early findings on the therapeutic use of hallucinogens in the treatment of substance use disorders, rigorous follow-up has not been conducted. To determine the safety and feasibility of psilocybin as an adjunct to tobacco smoking cessation treatment we conducted an open-label pilot study administering moderate (20 mg/70 kg) and high (30 mg/70 kg) doses of psilocybin within a structured 15-week smoking cessation treatment protoc…
The Behavioral Economics of Substance Use Disorders
The field of behavioral economics has made important inroads into the understanding of substance use disorders through the concept of reinforcer pathology. Reinforcer pathology refers to the joint effects of (a) the persistently high valuation of a reinforcer, broadly defined to include tangible commodities and experiences, and/or (b) the excessive preference for the immediate acquisition or consumption of a commodity despite long-term negative o…
Investigation of “Bath Salts” Use Patterns Within an Online Sample of Users in the United States
Bath salts" are synthetic stimulant "legal highs" that have recently been banned in the US. Epidemiological data regarding bath salts use are limited. In the present study, 113 individuals in the US reporting use of bath salts completed an anonymous, online survey characterizing demographic, experiential, and psychological variables. Respondents were more often male, 18-24 years old, and Caucasian/White with some college education. Past-year use …
Validation of the revised Mystical Experience Questionnaire in experimental sessions with psilocybin
The 30-item revised Mystical Experience Questionnaire (MEQ30) was previously developed within an online survey of mystical-type experiences occasioned by psilocybin-containing mushrooms. The rated experiences occurred on average eight years before completion of the questionnaire. The current paper validates the MEQ30 using data from experimental studies with controlled doses of psilocybin. Data were pooled and analyzed from five laboratory experi…
Psilocybin-Occasioned Mystical Experiences in the Treatment of Tobacco Addiction
Psilocybin-occasioned mystical experiences have been linked to persisting effects in healthy volunteers including positive changes in behavior, attitudes, and values, and increases in the personality domain of openness. In an open-label pilot-study of psilocybin-facilitated smoking addiction treatment, 15 smokers received 2 or 3 doses of psilocybin in the context of cognitive behavioral therapy (CBT) for smoking cessation. Twelve of 15 participan…
Classic psychedelic use is associated with reduced psychological distress and suicidality in the United States adult population
Mental health problems are endemic across the globe, and suicide, a strong corollary of poor mental health, is a leading cause of death. Classic psychedelic use may occasion lasting improvements in mental health, but the effects of classic psychedelic use on suicidality are unknown. We evaluated the relationships of classic psychedelic use with psychological distress and suicidality among over 190,000 USA adult respondents pooled from the last fi…
Examining Delay Discounting of Condom-Protected Sex Among Men Who Have Sex with Men Using Crowdsourcing Technology
Psilocybin produces substantial and sustained decreases in depression and anxiety in patients with life-threatening cancer
Cancer patients often develop chronic, clinically significant symptoms of depression and anxiety. Previous studies suggest that psilocybin may decrease depression and anxiety in cancer patients. The effects of psilocybin were studied in 51 cancer patients with life-threatening diagnoses and symptoms of depression and/or anxiety. This randomized, double-blind, cross-over trial investigated the effects of a very low (placebo-like) dose (1 or 3 mg/7…
Survey study of challenging experiences after ingesting psilocybin mushrooms
Acute and enduring adverse effects of psilocybin have been reported anecdotally, but have not been well characterized. For this study, 1993 individuals (mean age 30 yrs; 78% male) completed an online survey about their single most psychologically difficult or challenging experience (worst “bad trip”) after consuming psilocybin mushrooms. Thirty-nine percent rated it among the top five most challenging experiences of his/her lifetime. Eleven perce…
The Challenging Experience Questionnaire
Acute adverse psychological reactions to classic hallucinogens (“bad trips” or “challenging experiences”), while usually benign with proper screening, preparation, and support in controlled settings, remain a safety concern in uncontrolled settings (such as illicit use contexts). Anecdotal and case reports suggest potential adverse acute symptoms including affective (panic, depressed mood), cognitive (confusion, feelings of losing sanity), and so…
Long-term follow-up of psilocybin-facilitated smoking cessation
BACKGROUND: A recent open-label pilot study (N = 15) found that two to three moderate to high doses (20 and 30 mg/70 kg) of the serotonin 2A receptor agonist, psilocybin, in combination with cognitive behavioral therapy (CBT) for smoking cessation, resulted in substantially higher 6-month smoking abstinence rates than are typically observed with other medications or CBT alone. OBJECTIVES: To assess long-term effects of a psilocybin-facilitated sm…
Positive smoking cessation-related interactions with HIV care providers increase the likelihood of interest in cessation among HIV-positive cigarette smokers
Smoking cessation has proven to be a challenge for HIV-positive smokers. Patient and provider characteristics may provide barriers to smoking cessation. We aimed to identify characteristics associated with interest in cessation as well as characterize use of, current interest in, and provider recommendations for smoking cessation modalities. Data came from 275 HIV-positive smokers recruited online. Half (49.1%) of the sample was interested in qui…
Discounting of Condom-Protected Sex as a Measure of High Risk for Sexually Transmitted Infection Among College Students
Psilocybin-occasioned mystical-type experience in combination with meditation and other spiritual practices produces enduring positive changes in psychological functioning and in trait measures of pro…
Psilocybin can occasion mystical-type experiences with participant-attributed increases in well-being. However, little research has examined enduring changes in traits. This study administered psilocybin to participants who undertook a program of meditation/spiritual practices. Healthy participants were randomized to three groups (25 each): (1) very low-dose (1 mg/70 kg on sessions 1 and 2) with moderate-level (“standard”) support for spiritual-p…
Psychedelic therapy for smoking cessation
BACKGROUND: Recent pilot trials suggest feasibility and potential efficacy of psychedelic-facilitated addiction treatment interventions. Fifteen participants completed a psilocybin-facilitated smoking cessation pilot study between 2009 and 2015. AIMS: The aims of this study were as follows: (1) to identify perceived mechanisms of change leading to smoking cessation in the pilot study; (2) to identify key themes in participant experiences and long…
Perceived risk of developing smoking-related disease among persons living with HIV
Perceived risk of smoking is associated with smoking status, interest in quitting, cessation attempts, and quit success. Research is needed to explore risk perceptions of developing smoking-related disease among persons living with HIV (PLWH). Data came from 267 HIV-positive smokers who completed an online survey assessing perceived health risks associated with (a) generic smoking status; (b) generic non-smoking status; (c) their own personal cur…
Cessation and reduction in alcohol consumption and misuse after psychedelic use
BACKGROUND: Meta-analysis of randomized studies using lysergic acid diethylamide (LSD) for alcohol use disorder (AUD) showed large, significant effects for LSD efficacy compared to control conditions. Clinical studies suggest potential anti-addiction effects of LSD and mechanistically-related classic psychedelics for alcohol and other substance use disorders. AIMS: To supplement clinical studies, reports of psychedelic use in naturalistic setting…

Survey of subjective "God encounter experiences"
Naturally occurring and psychedelic drug-occasioned experiences interpreted as personal encounters with God are well described but have not been systematically compared. In this study, five groups of individuals participated in an online survey with detailed questions characterizing the subjective phenomena, interpretation, and persisting changes attributed to their single most memorable God encounter experience (n = 809 Non-Drug, 1184 psilocybin…
