“…Rushton and Jensen [33] emphasized that during the critical period of brain development, undernutrition can decrease the number of neurons and synapses, which are the biological bases of cognitive abilities (CAs). These studies consider social factors such as undernutrition, poor sanitary conditions and health, parasitic diseases, lack of hospitals, electricity, educational institutions and low rates of schooling, which are commonly found in countries with low socioeconomic status, to impede the full development of people's CAs [16,17,25,33,34].…”

The aim of this study was to investigate the effects of intelligence and income on nutrition in Brazil, by means of large-scale secondary data. The cognitive abilities of students were used as a measure of intelligence. In order to evaluate the nutritional quality of the population, the state hunger and undernutrition index (SHUI) was created. The intelligence explained 34% of the SHUI variation in the country. The development of the population’s intelligence influences the decrease in the rates of hunger and undernutrition.

“…Even though individual differences in psychological characteristics are quite different within each culture, betweennation differences in the average levels of intelligence and personality characteristics can also be substantial (Lv & Xu, 2016a;Lynn & Vanhanen, 2012). A large body of research has been devoted to cognitive differences between nations, and the recent advances in the intelligence literature show that intelligence has direct effect on wide range of socioeconomic outcomes (Meisenberg, 2012;Rindermann, Kodila-Tedika, & Christainsen, 2015;Salahodjaev, 2015aSalahodjaev, , 2015bSalahodjaev & Azam, 2015). In this article, we make an attempt to investigate the effect of intelligence on EWEB.…”

Cross-Country Evidence on the Link Between Intelligence and the Environmental Efficiency of Well-Being

Abstract. Recent studies have conceptualized sustainability as the environmental efficiency of well-being (EWEB). This paper makes an attempt to investigate the effect of intelligence on EWEB using data from 101 countries. Our results show that countries with high-IQ populations transform environmental consumption into well-being more efficiently. Moreover, we find little evidence in support of an inverted-U curve between economic development and EWEB, and thus our findings shed new light on the economic development-EWEB nexus. These findings are robust to the inclusion of additional explanatory variables and the use of alternative measurements of intelligence.

“…Conjuntamente, os dias escolares mais extensos e a utilização de programas de computador interativos, em salas de aula, afetam as habilidades acadêmicas e cognitivas dos alunos positivamente (Nisbett, 2009 Os índices de sobrepeso e de obesidade associam-se positivamente com as HC médias das populações dos países (Salahodjaev & Azam, 2015). Já a subnutrição e a fome possuem maiores prevalências nos países ou estados em que as pessoas têm menores médias de HC (Lynn & Vanhanen, 2002;Vanhanen, 2014 2) Porcentagem de crianças menores de dois anos de idade desnutridas;…”

The mean scores obtained by students from different countries in scholastic assessments correlate strongly with the average Intelligence Quotient (IQ) of the population of the nations. In this sense, the assessments that measure the knowledge of the students can represent the general intelligence of the inhabitants of a country. The present study investigated the influence of specific cognitive abilities (CA), general intelligence (aggregate index of specific CA) and per capita income on food and nutrition of the population of the 27 states of Brazil. Also they were analyzed the impacts of good food and nutritional quality and early schooling on the variation of the general intelligence of the inhabitants of those states. The average student scores, in different areas of knowledge, in the International Student Assessment Program, which assesses students in high school, were used as specific CA measures. The impacts of specific CA and general intelligence were calculated on two indices, created in this research, for each UF of Brazil: (1) the state hunger and undernutrition index (SHUI), composed of rates of malnourished children, previous malnutrition in children and adolescents, exclusive breastfeeding, poverty and extreme poverty due to caloric needs and consumption of fruits and vegetables in the UF of Brazil and on (2) the overnutrition state index (OSI), consisting of consumption of sausages, soft drinks, alcoholic beverages, ready meals and industrial mixtures, animal fat, sweets, confectionery, confectionery, fried salty foods and ice creams, percentages of overweight and obesity, Body Mass Index, individuals who want to gain weight and who want to lose weight. Overall intelligence and per capita income together account for 77% and 71% of SHUI and OSI variation, respectively, but only general intelligence or specific CA alone and statistically significant explained the variation of the SHUI and of OSI. General intelligence or specific CA are the factors that explain the associations between per capita income and food and nutritional inequalities of Brazil. The higher the specific CA or general intelligence of a UF population, the lower their rates of hunger and malnutrition, and the higher their percentages of overweight and obesity. Specific CA have almost identical influences to the impact of general intelligence on SHUI and OSI, which may give rise to a new definition of intelligence: mental development in any area of knowledge. From this definition, the analysis focus of intelligence studies can shift from the correlations between the various specific mental tests and the general factor (g), for the human being, the subject of knowledge, who is more intelligent not only by have a high IQ, but for having developed a specific CA. On the other hand, the percentages of children enrolled in school, from zero to three years old, breastfeeding rates and the percentages of people with caloric deficiency together explained 78% of the general intelligence variability of Brazil.
