Social ecology of intelligence and suicide in the United States

Two proxy variables for regional intelligence, state-level mean scores of 1994-2004 on the American College Test and of 1982, 1993, 1994, and 1998-2004 on the Scholastic Assessment Test, were consistently positively correlated with the averaged regional U.S. suicide rates of 1990-1994. The effects observed in these ecological (group-level) analyses were of small size, with correlation coefficients ranging from .05 to .25, thus mostly falling below the nominal statistical significance level. The present evidence nevertheless adds to several recent findings from international geographical studies by Lester and by Voracek of a positive association of intelligence and suicide mortality by indicating that this pattern may also exist on the within-nation level.     

Educational attainment and suicide rates in the United States

We examined the relationship between educational attainment and suicide rate in the United States for 2001. Suicide rates, adjusted for age, were compared with percentage of college graduates, median household income, and poverty in 50 states in 2001. The correlations of suicide rates with educational attainment and median household income were both negative and statistically significant. Poverty was not significantly related to suicide rates. We concluded that higher education and income were associated with a decrease in suicide rates in 2001. Data from other years require examination for this conclusion to be generalizable.     

State IQ and suicide rates in the United States

Previous findings pertaining to the direction (positive or negative) of the ecological correlation between intelligence and suicide rates in the USA have been conflicting. Using novel state IQ estimates, derived from the Scholastic Assessment Test, the American College Test, these tests combined, or the National Assessment of Educational Progress state scores, these estimates were not consistently associated to state suicide rates. Whereas ACT-derived state IQ was significantly positively correlated with suicide rates, the correlation with composite ACT-SAT-derived state IQ was significantly negative and with both SAT-derived and NAEP-derived state IQ also negative but not significant. Validity checks pointed to possible methodological problems with the state IQ estimates. Currently available estimates of state IQ, therefore, seem not appropriate to resolve the question of the direction of the ecological correlation of intelligence and suicide mortality across the USA.     

State IQ and elderly suicide rates in the United States

Paralleling previous findings with state suicide rates of the total population, the associations of state suicide rates of elderly persons with regional IQ estimates across the USA were inconsistent (positive, negative, or nil), depending on the source of available state IQ estimates used in the analysis. The implications of these findings and directions for further inquiry are discussed.     

Social correlates of youth suicide rates in the United States

The 1980 suicide rate of youths in the United States were found to be associated with three clusters of social variables: social integration, the age structure, and race/region. These associations also were found for older groups, suggesting similarities in the impact of social variables on regional suicide rates.     

British female academics and comparative psychology: attempts to establish a research niche in the early 20th century

Why was there a preponderance of women engaged in laboratory-based studies of animal behavior in Britain in the early years of the 20th century? As a new experimental subject with recently neglected potential, animal psychology then represented an opportunity for women to make further inroads into academic science. Because the study of psychology before World War I offered negligible professional opportunities for the application of the subject, the intake of students was restricted. Perhaps this encouraged academic access to it by aspiring female scientists who felt that career prospects, uncertain and socially unexpected of them in any case, were worth chancing for greater long-term rewards. The academic circumstances and contributions of 3 British female pioneers in experimental comparative psychology are discussed.     

High religiosity and societal dysfunction in the United States during the first decade of the twenty-first century

This study provides independent empirical evidence that bears upon the truth or falsity of recently formulated hypotheses regarding reciprocal relationships between levels of religiosity and societal dysfunction. Gregory S. Paul's findings, published in the Journal of Religion and Society (2005), Free Inquiry (2008), and Evolutionary Psychology (2009), have demonstrated that high degrees of theism are associated with high degrees of societal dysfunction among the prosperous democracies. Whereas his research employs numerous scatter diagrams and bivariate correlations involving measures of religiosity and societal dysfunction pertaining to 17 nation states, the current study's units of analysis are the 50 states and the District of Columbia. Additionally, the utilization of multiple regression analysis allows the detection of the effects of other potentially relevant explanatory variables, such as educational attainment, income level, and race. The findings are only minimally supportive of Paul's hypotheses regarding the contributions of high religiosity to societal dysfunction and to the effects of societal dysfunction upon religiosity. Simultaneously, the results of correlational and regression analyses attest to the more substantial explanatory power of the social inequality variables of education, income, and race. Accordingly, it is argued that "American Exceptionalism," when understood as referring to a society manifesting the coexistence of high levels of theism and high levels of societal dysfunction, is best explained by the United States' high degree of social inequality, compared with other modern industrialized democracies.     

Acculturation and suicide attitudes: a study of perceptions about suicide among a sample of Ghanaian immigrants in the United States

To investigate whether a relationship exists between acculturation and attitudes about suicide, 81 Ghanaian immigrants living in the U.S. who responded to a mail inquiry were selected to participate in the current study. This particular immigrant sample was chosen because although they represent a rapidly growing group in the U.S., they have been rarely studied. Respondents consisted of 42 women and 36 men (3 did not identify their sex), with a mean age of 29.5 yr. (SD = 10.6). Participants completed measures of acculturation and attitudes about suicide. Results indicated significant correlations between length of residency in the United States and negative suicide attitudes, and also between psychological acculturation and negative suicide attitudes. No significant relationship was found between behavioral acculturation and suicide attitudes. Furthermore, length of residency was a stronger predictor of suicide attitudes than other subjective measures of acculturation. Implications and suggestions for further research are discussed.     

The missing piece: a sociological autopsy of firearm suicide in the United States

Social, economic, violence, political, and gun access predictors of suicide and gun suicide were examined via sociological autopsy. The model predicting suicide rates overall had the best results, χ(2) (9, N=50)=5.279 (CMIN, the goodness of fit statistic that represents the minimum discrepancy between the unrestricted sample covariance matrix and the restricted covariance matrix) p=.809, [the goodness of fit statistic that represents the minimum discrepancy between the unrestricted sample covariance matrix and the restricted covariance matrix] indicating an excellent fit of the data and theoretical model. The model explained 76% of the variance in state suicide rates and was a significantly better predictor than one could expect by chance, F(6,43)=22.889, p<.001). All path coefficients were significant predictors of suicide with the exception of violence climate, which was not included. This study contributes to the theoretical knowledge by adding a comprehensive framework of analysis and model useful for prevention.     

Mikhail Lifshits and the fate of Hegelianism in the 20th century

In his essay “Das literarische Erbe Hegels” (“The fate of Hegel’s literary legacy”, 1931) Lifshits addressed the fate of Hegelianism in the first third of the 20th century. He observed a struggle surrounding Hegel’s heritage between Marxism on the one hand, and Neo-Hegelianism or ?the Hegel renaissance“ on the other hand and came to the conclusion that the only legitimate Hegel heir is—Marxism. According to Lifshits, Neo-Hegelianism exploits the “Hegelian state” to justify the modern power state by illegitimately shifting the meaning of the Hegelian concept of the state. Thanks to Kojève’s philosophy, a diffuse yet profound Neo-Hegelian influence continues to have an impact on modern thinking, which gives cause in this essay to examine Lifshits’ verdict on the illegitimacy of the Neo-Hegelian Hegel heritage by confronting his argumentation with Kojève’s Neo-Hegelian concept. So, this essay will update Lifshits’ perspective on the fate of Hegelianism and broaden it beyond the horizon that was available to Lifshits.     

Politics and naturalism in the 20th century psychology of Alfred Binet

Alfred Binet is internationally recognized as the "father" of the first intelligence test as well as the most faithful French representative of laboratory experimentalism. A historical analysis of his work is therefore necessary to get to a thorough comprehension of 20th century psychology. The present article, starting from Binet's intellectual path and from the suggestions of the previous historical literature, aims at providing fresh insights into Binet's work by trying to capture the intersections between Binet, his naturalistic culture and the political context in which he worked in the early 20th century, when he actively tried to apply experimental psychology to the pedagogical area. In fact, it is possible to underline, with reference to those years, an evident turn towards applications in Binet's psychological production. The article reconstructs the political and institutional background of Binet's research and shows how the naturalism and experimentalism he promoted were complementary to the solidarist conceptions that were particularly prevalent among those who supported his work during the Third Republic.     

Educational attainment, intelligence, interstate migration, and suicide rates in the United States: rejoinder to Abel and Kruger (2005)

Abel and Kruger (2005) reported a negative association of educational attainment and suicide rate across the United States. Given strong links between intelligence and educational attainment, this appears to be inconsistent with positive associations of intelligence and suicide rate reported in several other geographical studies. However, the apparent inconsistencies may reflect interstate migration within the U.S. adult population. Testing this hypothesis showed that interstate migration was more strongly related to state suicide rates than educational attainment. Thus, the different results obtained by Abel and Kruger could reflect migration effects, which for the U.S. might render adult-age indicators of educational attainment inappropriate to reflect regional variation in intelligence by place of birth.     

Issues in comparative psychology at the dawn of the 20th century

Comparative psychology emerged as part of the "new psychology" that took hold in the United States around 1900. Many of the issues that have occupied comparative psychologists throughout the 20th century were developed as research problems during this period. In some respects, comparative psychology was then an integral and widely respected part of psychology at large; in others, it was already marginalized. Issues emerging during this critical period set the program for the upcoming century and included those of methodology in the conduct of experiments and conceptual issues related to evolution, development, intelligence, and higher processes.     

Ancestry, genes, and suicide: a test of the Finno-Ugrian Suicide Hypothesis in the United States

There is now convergent evidence from classic quantitative genetics (family, twin, and adoption studies) and molecular genetic studies for specific genetic risk factors for suicidal behavior. This emerging research field has recently been supplemented by geographical studies concerned with the Finno-Ugrian Suicide Hypothesis (FUSH), which states that population differences in genetic risk factors may partially account for conspicuous geographical patterns seen in suicide prevalence. In particular, the European high-suicide-rate nations constitute a contiguous, J-shaped belt, spanning from Finland to Austria. This area maps onto the second principal component identified for European gene distribution, most likely reflecting a major migration event of the past (i.e., the ancestral adaptation to cold climates and the Uralic language dispersion) still detectable in modern European populations. The present research tested the hypothesis in the United States. Consistent with the hypothesis, available historical (1913-1924 and 1928-1932) U.S. state suicide rates were uniformly positively associated with available state proportions of reported American ancestries from European high-suicide-rate countries (Hungary, Lithuania, Poland, Russia, Slovakia, and the Ukraine). However, contrary to the hypothesis, available contemporary (1990-1994) suicide rates were uniformly negatively associated with these ancestry proportions. The findings of this first test outside Europe are therefore conflicting. A proposal based on the geographical study approach is offered to further the progress of investigations into the genetics of suicide.     

A thematic comparison of suicide notes drawn from Northern Ireland and the United States

Suicide is a global concern hence cross-cultural research ought to be central to national suicide prevention strategies. This study sought to investigate suicide notes drawn from Northern Ireland and the United States as these countries have broadly similar suicide rates but markedly different cultures. A theoretical-conceptual analysis of sixty suicide notes drawn from these countries, matched for age and sex, was undertaken based on a thematic model of suicide developed by Leenaars (1996) across countries. The results suggested that there were more psychological commonalities than differences. Two differences emerged which suggested that aspects of the interpersonal components may be more salient in Northern Irish rather than American suicides. It is argued that more wide-ranging cross-cultural studies are required to enhance our ability to identify and predict those most at risk from suicide.

The social environments of early infancy in Japan and the United States

The social environments of early infancy in Japan and the United States were compared in terms of the context of caregiving and the quality of the month-infant interaction. Mothers of 17 Japanese infants and 17 infants in the United States were interviewed in their homes about the experiences that they provided for their 4-month-old infants, and mother-infant interactions were recorded on videotape. Levels of parents' education were similar in both countries. The context of the infant's development varied substantially with culture. Mothers in the United States provided a greater variety of experiences on the HOME and care of Japanese infants tended to be more exclusively provided by mothers whereas care of infants in the United States was shared by fathers and other caregivers to a greater extent. Examination of behaviour frequencies during mother-infant interaction indicated that mothers in Japan provided their infants with more vocal input and more physical play than mothers in the United States and Japanese mothers were more vocally responsive to their infants' vocalizations.
