On April 24, 1945, a twenty-four-year-old Black former bartender and mechanic from Caguas named Marcial Hernández García (alias “Yombe”) entered the Insular Penitentiary at Río Piedras (popularly known as Oso Blanco).Footnote ¹ A week prior, the Caguas district court sentenced him to eight years for a bundle of offenses ranging from breaking and entering and multiple counts of theft to a crime against nature, all of which he claimed to have committed under the influence of drugs and alcohol. Behind bars, he was interviewed and studied by penitentiary health professionals, who were interested in his life before prison and his health while incarcerated.Footnote ² Psychiatrist José R. Maymí Nevares, for instance, concluded that Yombe suffered from mental maladjustment, or more specifically, episodes of bewilderment during which he observed “abnormal” and “undisciplined” conduct.Footnote ³ Several individuals familiar with him in Caguas before he was jailed confirmed his erratic state of mind. These potential advisors had since distanced themselves from him, telling parole officials he was “half-crazy.”Footnote ⁴

To treat Yombe’s mental instability, he was isolated in a cell and regularly observed. An intelligence exam (Wechsler-Bellevue test) administered by psychologist Juan B. Picart, on which the prisoner scored a 63 (indicative of mental deficiency), corroborated “signs of organic cerebral disease.”Footnote ⁵ Picart’s clinical and vocational analysis confirmed Yombe’s cognitive and applied shortcomings, leading prison technocrats to believe that mental infirmity was why he neglected to study or learn a new craft while in Oso Blanco. This could become a problem, as reform logic prevailed in the penitentiary alongside carceral capitalism.

When Yombe was finally eligible for parole between late 1948 and early 1949, officials rejected the prospect given that his mental state and behavior had not improved much. Parole officer María Casasnovas cosigned their reservations, and in the end, Yombe remained imprisoned. Still, penitentiary health professionals sensed that the man was treatable and therefore salvageable. They insisted that solitary confinement, psychiatric observation, psychological examination, social work interviews, an appropriate labor assignment, and sports would achieve his rehabilitation. In fact, Oso Blanco Classification and Treatment personnel forecasted Yombe’s rehabilitation as “regular,” so they went about preparing him for parole reconsideration. Health professionals viewed his impaired mind as surmountable, especially if addressed across rehabilitative techniques, and more importantly, as but a snapshot of a complicated, panoramic whole that included both the tangible and intangible.

This brief foray into Yombe’s experience, who was interviewed, studied, and deemed worthy of rehabilitation by an interdisciplinary group of penitentiary health professionals, reveals myriad, overlapping encounters between different health practitioners and convicts and the frequent exchanges and loops between them in a mixed-race society under US rule. At the microlevel, the interaction between Yombe and Picart was mediated by science and destabilized homogenous notions of Blackness. Prison authorities categorized Yombe as Black. Picart was also of color.Footnote ⁶ Sharing skin tone did not mean the two men were entrenched kin folk, though, for they had diverging class backgrounds. Whereas Yombe had worked in bars and gas stations and expressed wanting to be his own boss, ship logbooks indicate Picart frequently traveled to New York City, where he earned an MA degree at Columbia University Teachers College in 1946.Footnote ⁷ Both men negotiated settler colonial scenarios, albeit from very different positions and with different goals and outcomes in mind.

More broadly, Yombe’s case illustrates that multiple settler colonial traditions shaped how members of Oso Blanco’s Classification and Treatment Board (i.e., psychologists and those trained in social science disciplines like social workers) coevaluated incarcerated people in the 1940s and 1950s.Footnote ⁸ Spanish colonial ethnographic approaches to criminal science informed mid-century social scientists’ compilation of prisoners’ histories. These, in turn, allowed them to better “see” the entirety of the people under their scrutiny and in their care.Footnote ⁹ This happened in a laboratorial setting, however, which reflected eugenic American approaches to science, such as psychometrics, that arrived in Puerto Rico after 1898.Footnote ¹⁰ The result was a “creole” (racially mixed, race-neutral) nationalist science that blended Spanish and American colonial traditions, while contradictorily utilizing the resulting knowledge to reclaim Puerto Rico’s future.Footnote ¹¹

The blended creole science apparent in Yombe’s case and others like it in modern Puerto Rico substantiates insights about the multidirectionality of science and medicine in Latin American and Caribbean history.Footnote ¹² In the mid twentieth century, the Partido Popular Democrático (Popular Democratic Party, or PPD) and the statesman-turned-governor Luis Muñoz Marín presided over the rise and fall of Puerto Rico as a social laboratory.Footnote ¹³ During this era of multifaceted reform, health professionals promulgated social science research that was cognizant of prisoners’ humanity, showcasing that racialized colonial subjects created their own scientific expertise and used it for the purpose of national rehabilitation in the midst of unequal relations with the United States. Critical ethnography and psychometric tests enabled Puerto Rican social scientists to forge their own “objective” assessments of prisoners. The creole-appropriated projects of mapping convict minds, lives, and behaviors, rehabilitating them, and (re)integrating them into the Puerto Rican political economy and body politic helped mute and overturn long-standing colonial assumptions about tropical unfitness. “Repairing” prisoners positioned privileged creole technocrats to contribute to a broader project of rationalizing domestic self-government, a vision that came to fruition in 1951 via commonwealth status. The irony was that they aspired to rehabilitate inmates while reinforcing common tropes of their dysfunction.Footnote ¹⁴

Using a variety of sources, this chapter traces Puerto Ricans’ pursuit of a decolonized science, one that responded to the archipelago’s evolving health challenges despite biomedical progress and the reduction of mortality rates.Footnote ¹⁵ Penitentiary psychologists and social workers used psychometrics and ethnography to measure the intelligence, skill sets, and personalities of prisoners, and to signpost how to best uplift them. These diagnostic and descriptive tools revealed that convicts required discipline, tutelage, and treatment, but that they also had redemptive potential regardless of social difference. Socio-scientific interaction of this kind troubled linear notions of human progress, tempered professional preferences for certain technologies of power, and formed and made visible the value commitments of prisoners and the experts charged with evaluating and shepherding them.Footnote ¹⁶ Instead of seamlessly accepting the results of mental tests, social scientists put them into dialogue with inmate ethnographies to forge what to them were forward-looking treatment programs, illustrating how racialized racelessness and intersubjective exchanges transformed Puerto Rican corrections, at least for a time.

Blended Science

The history of science in Puerto Rico is as long as the history of the archipelago.Footnote ¹⁷ Puerto Rican science acquired cross-imperial and polyglot features in the late eighteenth and nineteenth centuries through vertical health interventions and studies of botany, disease, forensic pathology, and medicine.Footnote ¹⁸ In many of these accounts, characters of flesh, bone, and blood were relegated to the background. By the eve of the twentieth century, people-centered ethnographies increasingly characterized local scientific knowledge production. This shift was evident in the growth of social science studies, particularly a steady stream of anthropological and sociological literature about peasants, mental patients, and criminals.Footnote ¹⁹

Among the studies published in the late nineteenth century that shed light on Spanish colonial ethnographic research in Puerto Rico are those of the physician-criminal anthropologist José Rodríguez Castro. In the early 1890s, he published several medico-legal reports about crime and madness on the southern coast. One of his investigations spotlighted a Black adolescent named Isidora Gual who had strangled her infant son. Rodríguez Castro applied European ideas and ethnographic methods to Gual’s case to distinguish between her criminality and insanity. His narrative revolved around her youth, sensuality, lack of education, class and race background, regional origins in Guayama (a Black part of the island associated with sugar plantation slavery and witchcraft), and family history of mental instability. In addition to only possessing fifty-three centimeters of cranial circumference, the generally somber Gual endured numerous spells of hunger and sickness with her child.Footnote ²⁰ The precise answer as to why she killed the boy lay somewhere between her individual decision-making and the social conditions shaping her circumstances, a position that contrarian colleagues contested.Footnote ²¹ Truly understanding the case, Rodríguez Castro wrote, necessitated examining “all her life,” her decisions over time, and moral and physical factors.Footnote ²²

Resolving health problems, such as the prevalence of alcoholism and anemia, in part instigated the turn toward multidimensionalizing people and using them to explain crime, disease, and other infirmities in Spanish colonial Puerto Rico. US military scientists subsequently recast Puerto Ricans as disease-ridden rural subjects.Footnote ²³ In the early twentieth century, scientific knowledge production in Puerto Rico primarily revolved around biomedicine and the focus of the economy, agriculture. During the interwar years, nutrition became a public health concern and biochemists, home economists, agronomists, and social workers promoted rural hygiene programs.Footnote ²⁴ By the mid twentieth century, the wombs of women increasingly garnered the attention of scientists.Footnote ²⁵ An exception to this biomedical-corporeal rule surfaced in the mid-1910s, with the anthropological works linked to the initial phase of the New York Academy of Sciences’ Scientific Survey of Porto Rico and the Virgin Islands. Although Franz Boas and John Alden Mason composed thick descriptions of Puerto Rican Indigeneity, rural oral folklore, and Blackness while nurturing liberal-reformist colonial interests to remake an “empty” colony in the image of a “civilized” metropole, it was not until the 1940s and 1950s that ethnography fused to modern Puerto Rican statecraft.Footnote ²⁶

Human science in Puerto Rico, then, has historically responded to colonial-imperial politics and prerogatives. Under Spanish rule, ethnographic science attentive to socioeconomic and spiritual conditions prevailed. Under American rule, science became more laboratorial and rigid.Footnote ²⁷ Puerto Rican scientists of all persuasions continued to tout the importance of the laboratory under colonial-populism, but they also rediscovered ethnography as a tool that could help address the dual challenges of crime and stagnant colonialism. While the Spanish and US-Americans had contrasting rehabilitative logics, in both cases these emanated from the intersection of biopower and custodial-regulatory practices.Footnote ²⁸ What rehabilitation looked like on the ground under colonial-populism, however, mirrored the socio-scientific outlook of Muñoz Marín and the PPD, who dominated Puerto Rican politics for several decades and articulated a “reformed colonialism” rather than reinforcing colonialism proper or insisting on independence.Footnote ²⁹ The colonial-populist project of the PPD merged state-controlled development, modernization, and “democracy” without rupturing cultural and political bonds with Spain and the United States, respectively.Footnote ³⁰

A major site where Puerto Rican leaders hoped to manufacture civic foot soldiers for this project was the Río Piedras scientific corridor, a cluster of welfare institutions located on the outskirts of San Juan close to the University of Puerto Rico-Río Piedras (UPR-RP) campus, an agricultural experiment station, and a leper colony in Trujillo Alto.Footnote ³¹ Oso Blanco (Figure 6.1), modeled after Sing-Sing penitentiary in New York, opened in 1933 and was the capstone of a transinstitutional complex that included the prison, an insane asylum, and a tuberculosis hospital.Footnote ³² Each of these institutions reinforced one another in a common epistemic fabric. A culture of rehabilitative corrections that triply pathologized inmates emerged on the grounds of the complex, where inmate bodies, minds, and behaviors served as raw material for a local yet cosmopolitan medical class whose research was well-disposed and self-aggrandizing.Footnote ³³ In this context, incarcerated people conveyed their stories to penitentiary technocrats, while social scientists’ narratives of inmates exposed their desires to resurrect the Puerto Rican “nation.”

Knowing Precedes Rehabilitating

In the early twentieth century, academia helped advance and reinvent settler colonialism. Universities and scholars contributed to forging purposeful knowledge about colonies and drawing the boundaries of growing but racialized and exclusionary academies.Footnote ³⁴ In the Western hemisphere, US-American scholars in the humanities and social sciences approached South America with fresh eyes to ingrain or reject prior generalizations and stereotypes of the subcontinent. Their research laid the groundwork for a new apparatus of knowledge in the service of inter-American relations, imperial hemispheric hegemony, and informal empire.Footnote ³⁵

Puerto Rico’s flagship university (founded in Río Piedras in 1903) and Columbia University played key roles in informalizing the US Empire and building local capacity for education and the health and social sciences.Footnote ³⁶ Columbia made inroads into Puerto Rico in the 1910s and 1920s, when its faculty documented folkloric traditions and established a tropical medicine school in San Juan. In 1915, the “father of American anthropology,” Franz Boas, traveled to the Caribbean and participated in the Scientific Survey of Porto Rico.Footnote ³⁷ He and the archeologist and linguist, University of California-Berkeley graduate John Alden Mason, together researched Puerto Rican Indigeneity, presumed to have been long decimated in the wake of Spanish colonial expansion in the sixteenth century. Later, Boas supervised Mason’s research on rural peasant (jíbaro) and “negro” Puerto Ricans – the still living and visible portions of island identity by the mid twentieth century – efforts that “rescued” the equivalent of reams of highland oral folklore spanning poetry, sayings, songs, riddles, and folktales, and that documented Black vocabulary, religion, medicine, and customs.Footnote ³⁸ Meanwhile, the tropical medicine school was inaugurated in September 1926 and operated as an imperial research outpost. It was celebrated as a private–public partnership and testament to North Americans’ and Puerto Ricans’ commitment to forging a shared America and equality in hemispheric relations. Asymmetrical relations between metropole and colony persisted unabated, however.Footnote ³⁹

Columbia faculty again pushed the boundaries of Puerto Rican social science in the mid twentieth century. After World War II, UPR-RP’s new Center for Social Research commissioned a large-scale study to determine how modern social science could be employed to examine and resolve Puerto Rico’s social and economic problems. Anthropologist Julian Steward helmed the study, which was published in 1956. The People of Puerto Rico focused on how modernization affected local subcultures and underscored that health and welfare programs on the island had therapeutic and political significance.Footnote ⁴⁰ While Puerto Rican authorities weighed the impact of social science on statecraft, penitentiary social scientists like Picart lent their expertise to raising convicts from mental and social death. In both cases, acts of knowing preceded acts of rehabilitation.

When Oso Blanco was inaugurated in May 1933, Puerto Rico’s appointed governor, James Beverley, highlighted the prison’s modernity. This meant a concrete structure with sanitary facilities, the efficient use of space inside and of land surrounding the prison, self-sufficient (and later profitable) institutional productivity, and the application of social sciences like criminology.Footnote ⁴¹ Modernity also signified professional subjectivities linked to notions of rationality and progress.Footnote ⁴² It connoted humanizing punishment, which manifested in the attempted procurement of regenerative treatment.Footnote ⁴³ Colonial and local authorities alike envisioned Oso Blanco as a site of physical and mental rehabilitation. According to Attorney General Charles Winter, it was a place where convicts would be inculcated with healthy and moral habits through labor, education, and science. The point was to return “useful citizens” to their families, their communities, and society devoid of “criminal inclinations.”Footnote ⁴⁴ But a decade-plus would pass before the social sciences became fixtures at Oso Blanco.

Socio-scientific classificatory schemes, methods, and research in Puerto Rican corrections interfaced with intellectual currents emanating from the US mainland. In a paper published shortly after World War II by federal prisons official Frank Loveland, who around the same time was contracted by Puerto Rico’s government to conduct a critical study about incarceration there and suggest improvements, he stressed the variability of rehabilitative ideas. Analyzing corrections in the periphery taught Loveland that rehabilitation was a multifaceted, cooperative process involving individuals and institutions. Without cooperation from both sides, constructive results could not be obtained.Footnote ⁴⁵ Social scientists, critical ethnography, and psychometrics formed part of Loveland’s arsenal to streamline the holistic improvement of incarcerated people.

By the mid-1940s, mental tests had become a vital instrument of prison classification by opening different pathways to work toward the institutional adjustment of inmates, their rehabilitation, and their eventual societal reintegration. With these goals in mind, the mental exams of the era sought to measure the intelligence, skills, and personalities of incarcerated populations.Footnote ⁴⁶ In Puerto Rico and elsewhere, prison authorities believed that mental test results would clarify treatment paths for inmates. They also became synonymous with literal and symbolic health in Oso Blanco at a time when elite Puerto Ricans aimed to redefine the colonial pact with the US government amid exorbitant poverty, overpopulation, economic transformation, and political crisis.Footnote ⁴⁷ Carceral health professionals associated with the PPD contributed to building a local constituency that bore evidence of this reformist undertaking. Racially diverse convicts were perceived as candidates in this vein. To an extent, this distinguished the Puerto Rican approach to carceral rehabilitation from the eugenic carcerality flourishing in the United States. Indeed, creole rehabilitation sought to (re)integrate the races anthropologists like Boas and Mason were so eager to disjoin earlier in the century. Still, penitentiary social scientists deployed rehabilitative techniques that revealed the caprices of scientific medicine and the spurious, philanthropic university-based research informing it.Footnote ⁴⁸

Psychometric Testing

Since the late 1800s, psychometric tools have served as technologies of power that create normative frameworks for thinking about racialized people.Footnote ⁴⁹ They claim epistemological consistency and ontological universalism but can also be tools of juridical power and social control. The globalization of psychometric instruments in the twentieth century failed at universalizing “the human” yet contributed to colonial expansion. In mid-century Puerto Rico, neither Spanish nor American colonial frameworks were hegemonic. The creole nationalization of science and parallel pursuit of comprehensive human science under colonial populism subverted exclusively Spanish or American approaches to rehabilitation. Spanish, American, and creole flows of scientific knowledge production crashed into one another in the first half of the 1900s, with the latter becoming prominent at mid-century. Creole supremacy circumvented conventional exchange relations, reversed value, and upset predominant social structures and hierarchies associated with settler colonialism.Footnote ⁵⁰ The colonial conceits that informed acceptable manifestations of modernity and state formation remained visible in the ways psychometric tools reproduced certain standards and tropes during the era of the PPD, but were also translated over.

The development and use of psychological tests and measures in the West and Puerto Rico spans more than a century.Footnote ⁵¹ In 1920, adaptations of the Pintner tests of Non-Verbal Abilities circulated on Puerto Rico’s main island; the Stanford Achievement test then appeared, by 1925.Footnote ⁵² These were followed by other exams administered to public school students and incarcerated youths.Footnote ⁵³ In 1927, for example, Attorney General George Butte, who was later active in the Philippines, reported that University of Puerto Rico psychologists completed an educational and mental survey of imprisoned young people in Mayagüez, using, among other tests, the Stanford Test of Ability, which had been previously used by the Commission from Columbia University in a study of public school children.Footnote ⁵⁴ Clinical psychological services, on the other hand, were not routinely offered in psychiatric hospitals, facilities serving veterans and children, and prisons until the 1940s and later.Footnote ⁵⁵ This slow expansion coincided with the maturation of psychology as an academic discipline emphasizing mental processes, introspection, behavior, and interpersonal relationships.Footnote ⁵⁶

Puerto Rican psychologists trained in the United States and elsewhere aspired to develop and perfect mental tests attuned to the local linguistic and cultural milieu. This was because cultural mistranslation weakened the reliability of these diagnostic tools. Therefore, it was difficult for Puerto Ricans to obtain the expected mean Intelligence Quotient (IQ) of 100, the prevailing Anglo standard. A clear bias emerged when speakers of languages other than English were tested within parameters designed for English speakers. Standardized culture-free tests could universally estimate the intellectual functioning and manual capabilities of different groups, in theory resulting in more equitable assessments of colonized people.Footnote ⁵⁷

Multiple tests were adapted in Puerto Rico between the 1930s and 1950s. These included the Wechsler Intelligence Scale, the Binet Intelligence Scale, and the Goodenough Draw-a-Person test.Footnote ⁵⁸ Reliance on mental tests in Oso Blanco aligned with the growth of psychology in Puerto Rico at large. Prison psychologists connected to UPR-RP assessed the intelligence, cognitive and mechanical abilities, and personalities of convicts. Exam results reiterated to the Classification and Treatment Board that inmate minds harbored rich data that could and should be scientifically excavated, explained, and repurposed. In mapping prisoners in this way, penitentiary social scientists laid bare their own moral and behavioral preferences as well as those of Puerto Rico’s criminal-legal system and government.Footnote ⁵⁹ From their collective point of view, the end of a rehabilitated Puerto Rico “free” of colonial mismanagement justified the means of utilizing uneven psychometrics on prisoners to confirm their dysfunction and redemptive potential.

Pursuing Comprehensive Human Science

Oso Blanco endured scientific growing pains in its first decade of existence. Shortly after officially opening in 1933, the penitentiary lacked a psycho-pathological clinic to examine, diagnose, and treat convicts suffering from mental lesions.Footnote ⁶⁰ The next year, in 1934, Attorney General Benjamin Horton encouraged Puerto Rican legislators to carve carceral mental health positions into the new fiscal year’s budget. A psychiatrist and psychologist were “indispensable” for the study of prisoners’ “defects” and treating the “mental disorders” either caused or influenced by the crime(s) they committed, Horton insisted.Footnote ⁶¹ As of 1935, the posts still had not been created.Footnote ⁶²

There is little to no mention of carceral mind science in Puerto Rican government justice publications between the mid-1930s and mid-1940s. By 1946, psychiatric and psychological services were routine in Oso Blanco and overlapped. Psychological testing fell under the umbrella of psychiatry in terms of government reporting. Attorney General Enrique Campos del Toro, for instance, observed that “The number of new cases taken care of during the fiscal year by the psychiatrist at the Penitentiary were 138, of which the majority were cases of mental deficiency, psychopathic personality and psychoneurosis. Fifty-seven did not reveal apparent mental disturbances.”Footnote ⁶³ Mental tests helped prison authorities draw these conclusions. Governor Jesús Piñero relayed the following year, in 1947, that “Medical care to the indigent and public welfare activities in general increased throughout the Island, and a modest educational program [and census] on mental hygiene, with special emphasis on the problem of the feebleminded, was undertaken.”Footnote ⁶⁴ To be feebleminded was fused to promiscuity, criminality, and social dependence, equated “mental deficiency,” and denoted a level of functioning just above “idiocy.”Footnote ⁶⁵ Puerto Rican penitentiary health professionals imbued the category with similar opprobrium in their estimations of incarcerated rural people in the mid twentieth century.Footnote ⁶⁶

Psychometric exams of convicts were administered on the UPR-RP campus and inside the penitentiary. Performing well or poorly on intelligence tests did not automate or preclude rehabilitation, though. For example, in September 1948 Picart assessed Enrique Carmona – a spoiled, “rebellious” seventeen-year-old wheat-colored (trigueño) prisoner from Toa Alta.Footnote ⁶⁷ Carmona took the Wechsler-Bellevue test (Form I) on the UPR-RP campus and earned a complete score of 56, which meant he was “mentally retarded” or a “high moron.”Footnote ⁶⁸ However, Carmona had “psychological potential” that could bear fruit “under favorable environmental conditions.”Footnote ⁶⁹

In contrast, in January 1949 Picart evaluated a thirty-one-year-old white “psychopathic” prisoner who grew up between San Juan and New York named Santiago Ocasio Soler.Footnote ⁷⁰ Picart used the Wechsler-Bellevue to secure numerical values for the inmate’s verbal and manual skills by having him respond to arithmetic problems, order blocks, and finish drawings. There was a discrepancy between Ocasio Soler’s verbal and nonverbal scores because he took longer than expected to complete the former and was too sure of himself on the latter. Yet, his “mental deterioration” was an “insignificant 7 [percent],” and overall, he scored a 118 (in the normal superior range), a number that exceeded the Anglo standard of 100.Footnote ⁷¹ Like Carmona, Ocasio Soler was deemed rehabilitable. In both cases, a psychologist of color (Picart) presided over administering and explaining their mental test results, an inversion of the presumed racial and scientific orders.

Oso Blanco Classification and Treatment practitioners had lucid exchanges about these and other cases and shared their research with one another. Mimicking developments in the United States to a degree, psychometric tools in Puerto Rico formed part of a culture of observation and evaluation that consolidated and expanded vertical forms of social control.Footnote ⁷² Notwithstanding the limits of many exams, psychologists like Picart deployed a variety of mental tests to determine on which minds different ones could be applied. His work, in conjunction with the efforts and interpretations of the Classification and Treatment Board, tended to essentialize “mentally deficient” prisoners. Convicts thus served as psychological specimens. But many social scientists also valued the “egalitarian” creed of the PPD and wanted the prisoners striving for rehabilitation to do so as well. As convicts showed signs of conforming progress, the liberatory effects of colonial-populist rehabilitation became more pronounced. Prisoners were corralled and studied in Oso Blanco, where social scientists viewed them as objects of research. Just as significantly, social scientists desired to comprehensively understand and civically redeem convicts, transforming the meanings of citizenship and socio-scientific knowledge production in a settler colonial context.Footnote ⁷³

Redeemable Prisoners

Rehabilitative corrections flourished in the mid twentieth century.Footnote ⁷⁴ In Puerto Rico, Classification and Treatment officials investigated the lives of convicts, generated socioeconomic portraits of them, and organized health and social science data they later channeled into treatment programs.Footnote ⁷⁵ The director of Socio-Penal Services compiled findings and approved or modified prescribed plans. Treatment programs covered the medical, social, psychiatric, psychological, educational/vocational, and religious-spiritual aspects of rehabilitation. They usually concluded with a bottom line indicating whether individual prisoners could be rehabilitated at all. Crucially, incarcerated people had little to no say in whether they wholeheartedly consented to such practices, for at the time human subjects research was not legally micromanaged. Still, degrees of reciprocity were built into the human subject-researcher encounter, even if on highly unequal terms.

Classification and Treatment personnel utilized variable diction to convey inmate rehabilitative prospects. Proclaiming that prisoners were “rehabilitable” meant they were salvageable physically, mentally, socially, morally, and civically. Psychometric exams such as the Wechsler-Bellevue test, the Otis Mental Ability test, and the Rorschach Inkblot test either set the interpretive tone for Classification and Treatment Board efforts or built on already available ethnographies of convicts. In short shrift, however, board practitioners rejected exclusively considering IQ. Instead, they made a habit of contemplating exams intersectionally, meaning that Classification and Treatment experts believed multiple exams disclosed more together about individuals’ rehabilitative prospects than apart. Although mental tests pointed to the intellectual, interactive, and mechanical “deficiencies” of inspected prisoners, they also served as a compass for the prison technocrats charged with crafting treatment programs. Regardless of inmate identities or the nature of their crime(s), they were generally considered eligible for rehabilitation – even if getting there would be an uphill climb. This does not mean that categories like race, class, or sexuality were irrelevant relics of a bygone era. Rather, health professionals defied and contradictorily engaged them to achieve the more pressing goals of self-government and constituency building.

The confluence of convict ethnographies, mental tests, and treatment programs repeatedly surface in the archival record. For example, in March 1950 prison authorities reviewed the case of a twenty-five-year-old white prisoner from Cayey serving time for mutilation named Onofre Rodríguez López. Classification and Treatment official Gloria Umpierre reported that this convict was well-educated, and that he appeared to be a “trustworthy,” “serious,” and an all-around “normal” person.Footnote ⁷⁶ Perhaps most importantly, he showed repentance for his crime, possessed an excellent attitude, and was willing to adapt to what authorities demanded of him. He was a “good” case for rehabilitation. These conclusions would seem to suggest that Rodríguez López’s whiteness dictated Umpierre’s favorable assessment. However, his exam results divulge other interpretations.

Rodríguez López underwent protracted testing while incarcerated. He earned a high average score of 118 on the Otis test, above the Anglo standard of 100. More impressive was the fact that he answered questions quickly and correctly. Rodríguez López scored 39 points on the Bell Adjustment Inventory, which implied that he was “relatively well-balanced emotionally” compared to his immediate peers.Footnote ⁷⁷ Yet, his social skills needed improvement, for he was an “isolated type.”Footnote ⁷⁸ The answers he gave to questions about interpersonal interactions (21 total) exposed his social shortcomings. In short, being white did not mean he had flawless social prowess. Psychologists also probed Rodríguez López’s manual ability via the MacQuarrie test. He boasted average mechanical ability overall, performing well on the relational awareness, speed, and visual portions of the test, but underperformed on others. Prison officials recommended that the convict be given vocational work assignments to take advantage of the skills he had, and to cultivate and strengthen the ones he lacked. Interviews and religious services could further enrich his rehabilitation process, experts believed.Footnote ⁷⁹

As Rodríguez López’s case suggests, mid-century Oso Blanco social scientists believed that determining intelligence had to be complemented by the measurement of nonintellectual characteristics, such as manual skills and/or personality traits.Footnote ⁸⁰ The pattern is visible in cases of convicts of color as well. For example, in April 1950, Oso Blanco’s Classification and Treatment Board studied a twenty-seven-year-old Mulatto prisoner from Guaynabo serving time for homicide named Antonio Hernández Alamo. The “always smiling” Hernández Alamo impressed board members as “trustworthy” and “humble” but also as “a bit ignorant” and not in full control of his emotions.Footnote ⁸¹ He earned a 77 on the Otis test, a borderline deficient score. If exposed to interviews, religious guidance, challenging recreational activities like reading, and agricultural labor therapy, Hernández Alamo was a “good” case for rehabilitation. In fact, the prisoner teemed with “plenty of rehabilitable material.”Footnote ⁸² His mixed-race background did not disqualify him.

Hernández Alamo’s Otis test result was but one component of a more comprehensive psychology and broader human science that also depended on a social worker’s evaluation of his personality. In his case and others, penitentiary social scientists bridged ethnography and psychometrics. A thirty-eight-year-old Black asthmatic inmate from Guayama serving time for homicide named Adolfo Ortiz Gutiérrez, who “feared the dark” and was tortured by nightmares about ghosts, is another case in point.Footnote ⁸³ According to Classification and Treatment experts, who evaluated the convict in July 1950, he appeared to have “emotional problems,” found “lying satisfying,” and earned a 74 on an Otis test (borderline intellectual deficiency). These findings convinced them that they needed to administer personality tests to diagnose and treat Ortiz Gutiérrez more effectively. He had a “regular” chance to be rehabilitated. Interviews, religion, reading, and films could help bring him back from the mental and social brink.Footnote ⁸⁴

While white prisoners scoring in the normal range or exceeding it on a given intelligence test and mixed-race or Black prisoners scoring in the borderline deficient or inferior range can certainly be interpreted as settler colonial social science in action, that Oso Blanco social scientists experimented with combinations of tests in either racial scenario is suggestive of their awareness of the inequities baked into psychometrics and the need to evaluate incarcerated people on the basis of other shared criteria. Even if we assume prisoners of color were exclusively marginalized in this regard, a low intelligence score and rehabilitation were not mutually exclusive. This was the case for Salvador García Salamán, for instance, a twenty-one-year-old Black convict from Río Grande incarcerated at the Zarzal penal encampment in 1953 whose “below average intelligence” failed to raise serious concerns about his rehabilitative prospects.Footnote ⁸⁵

The opposite could also be true. For example, Picart administered a Wechsler-Bellevue test to a forty-six-year-old Black inmate from Santurce named Pedro Sánchez Alvarez in December 1948. The convict scored in the normal range (93). In his qualitative analysis, Picart noted that Sánchez Alvarez had satisfactory immediate and deep past memory, satisfactory mental concentration, and a “great ability to comprehend practical, real-life situations and to resolve situations involving arithmetic reasoning.”Footnote ⁸⁶ He expressed himself easily with ample vocabulary. The strengths and promise Picart saw in Sánchez Alvarez contrasted sharply with opinions of him shared by several of his immediate family members, who labeled him a “lost cause.”Footnote ⁸⁷ Here communal opprobrium did not flow from social scientists, but from Sánchez Alvarez’s own brothers and other kin. For every García Salamán or Sánchez Alvarez, however, there was someone who incarnated socio-scientific stereotypes. A twenty-six-year-old Mulatto prisoner from San Juan named Ricardo Estrada Padilla, for example, combined “below average intelligence” and “criminal tendencies.” These put his rehabilitation in jeopardy but never annulled it.Footnote ⁸⁸ Similarly, health professionals understood a quinquagenarian Mulatto from Coamo named Sandalio Mateo Vázquez as a “suspicious hypocrite” with “below average intelligence,” yet he was “rehabilitable.”Footnote ⁸⁹

Prisoners’ crimes, their backgrounds, and their (un)favorable personality traits and test scores did not automatically qualify them for or disqualify them from rehabilitation. Education, labor therapy, social orientation, religious services, and so on could transform convicts, although this was not guaranteed. While psychologists and social workers had occasion to belittle and racialize convicts, implicit in their mapping prisoners’ worlds and articulating rehabilitative programming for them was the belief that inmates could be raised from living death. Social scientists and inmates together made the human sciences more human in a place (the prison) where dehumanization was and remains the expected norm. There, race largely functioned as a pivot on which creole science partially turned at a time when colonial-populists reimagined Puerto Rican national identity on race-neutral terms.

Conclusion

As Puerto Rican rehabilitative corrections hit their stride in the mid-1940s and 1950s (though not without challenges and shortcomings), Puerto Rico’s government contracted federal consultants to conduct studies of the penal system. It was not until later in the 1950s and 1960s that justice officials finally implemented some of the recommendations put forward by the studies.Footnote ⁹⁰ University of Puerto Rico-Río Piedras social workers drew from the studies to renew the promise of Puerto Rican rehabilitative corrections. In a critical analysis published in 1959, Rosa Celeste Marín, Awilda Paláu de López, and Gloria Barbosa de Chardón chronicled the work of contemporary university social science faculty in the prison system. Faculty assessed the personalities of maximum-security prisoners incarcerated in Oso Blanco and found that many of them tested as “mentally deficient” and were vulnerable to ongoing mental infirmity and recidivism.Footnote ⁹¹ To gather the data leading to these and interrelated findings, social scientists administered a diverse batch of psychometric tests: the Porteus Maze, Rorschach, Thematic Apperception, Draw-a-Person, and Bender-Visual Motor Gestalt tests. Psychologists also put exam results into conversation with ethnographic information about convicts. The collective data laid bare the psychological features of each inmate, as well as tendencies in their emotions, thinking, and behavioral and cognitive functioning.Footnote ⁹²

Discussion of prisoners’ mental test results increasingly revolved around their dangerousness and propensity to mentally deteriorate when released from prison, however. A growing pessimism surrounding prisoner rehabilitation, flashes of which were apparent in the 1950s, gained momentum in Puerto Rico by the mid-1960s, evidenced by an uptick in studies that accepted the premise of criminal pathology yet lacked the rigor of previous generations to confront it.Footnote ⁹³ This coincided with successive governments across Puerto Rico’s party divide suffocating the rehabilitative ideal in the decades that followed.Footnote ⁹⁴ No longer were social science tools and methods viewed as pathways toward convict redemption. Instead, they functioned as instruments of intense pathologization and othering, which aligned with how US researchers and authorities trafficked in them across groups and national borders earlier in the century.Footnote ⁹⁵

In the mid twentieth century, Puerto Rican social scientists exposed convicts to Spanish and American rehabilitative logics and practices. They transcended binaries (Spanish and US colonialism, Black and white, researcher and research subject) to foster a creole science and pugilistic nationalism that aspired to prove that prisoners could be rehabilitated and become colonial-populist citizens. This nationalism countered the American settler colonial image of Puerto Ricans as perpetual tutees. In a sense, Puerto Ricans pursued a decolonized science in the mold of their African peers, who as Erik Linstrum has argued, utilized psychology to disclose the limits of British imperial authority.Footnote ⁹⁶

While the mid-century social scientists involved in evaluating prisoners often cast them as deficient, returning incarcerated people of all colors to society as productive laborers, family providers, and citizens – indeed, as human capital – illustrated that the colonial-populist (and later commonwealth) state just might live up to its racial democracy rhetoric.Footnote ⁹⁷ Socio-scientific research behind bars also showed that Afro-Puerto Rican health professionals like Picart could lay claim to scientific knowledge production, invest the epistemological riches in a more equitable domestic future without invalidating the relationship between metropole and colony, and unsettle assumptions about who got to possess research subjects and exercise health authority. Even though it was included as a category for describing incarcerated research subjects, race played a restrained role in inmate rehabilitation. The equity project within Puerto Rican corrections was paradoxical and failed, however, precisely because it depended on extracting pain and damage narratives from racially heterogeneous Puerto Ricans of perceived lesser status in the first place.

Colonial-populist Puerto Ricans’ alternative deployment of social science contributed to Puerto Rico’s modernization process but not in a way that automatically segued into rigid race-based exclusion.Footnote ⁹⁸ Whereas anthropological ethnography is now cast as a valuable instrument in the struggle against systems of oppression, particularly in the Western academy, this was not always the case. Intelligence tests, for their part, are still being used for reactionary purposes. Social science literature linking race and intelligence continues to be published, and it appears the social science community that works on intelligence accepts this without challenge notwithstanding their recognition of the ethno-racial biases and controversies that have long tainted psychometrics.Footnote ⁹⁹ The case of mid twentieth-century Puerto Rico, then, offers an inviting vantage point from which to understand how carceral human science, ironically, lent itself to the search for and realization of other realities, well in advance of our own preoccupation with reimagining the world.
