The debate on religiosity and intelligence explores the link between religiosity and issues related to intelligence and educational level (by country and on the individual level). Debates over religiosity may consider religious belief and/or practice, and may compare to atheism or to lack of religious affiliation or to lack of religious practice. Most of the recent scientific studies have found a negative correlation between IQ and religiosity. On the individual level, the education level is positively correlated with a belief in a god in African countries, and negatively correlated in Western countries. Studies have shown a strong link between national average IQ and atheism in society. Research shows of twelve countries with atheism over 40%, all except two are in a moderate average IQ range of 94 to 100, with one lower IQ than that range (Cuba) and one higher IQ than that range (Japan). Countries with an average IQ below 92 are overwhelmingly religious, with atheism under 10% (with the exception of Cuba), and often less than 2%. Two of the nine countries (22.2%) with a high average IQ above 100 are more than 25% atheist (Japan and South Korea). The highest IQ nation, Singapore, has an atheism rate of 12%, with a further 5% having no specific religious affiliation (but not self-identifying as atheist). Although statistical studies show that the poorest countries tend to be more religious, experts suggest that the reason may be that religions play a more active social, moral and cultural role in those countries.〔 Religions in wealthy countries used to have a more specific moral and spiritual role. ==Summary of research and definitions of terms== Intelligence is a property of the mind that encompasses many related abilities, such as the capacities to reason, to plan, to solve problems, to think abstractly, to comprehend ideas, to use language, and to learn. There are several ways to more specifically define intelligence. In some cases, intelligence may include traits such as creativity, personality, character, knowledge, or wisdom. However, some psychologists prefer not to include these traits in the definition of intelligence. A widely researched index or classification of intelligence among scientists is Intelligence Quotient (IQ). IQ is a summary index, calculated by testing individuals' abilities in a variety of tasks and producing a composite score to represent overall ability, e.g., Wechsler Adult Intelligence Scale. It is used to predict educational outcomes and other variables of interest. Others have attempted to measure intelligence indirectly by looking at individuals' or group's educational attainment, although this risks bias from other demographic factors, such as age, income, gender and cultural background, all of which can affect educational attainment.〔 Dissatisfaction with traditional IQ tests has led to the development of alternative theories. In 1983, Howard Gardner proposed the theory of multiple intelligences, which broadens the conventional definition of intelligence, since the cognitive or mental capacity of an individual logically includes all forms of mental qualities, not simply the ones most transparent to standardized IQ tests. The categories of intelligences Gardner proposes are logical, linguistic, spatial, musical, kinesthetic, naturalist, intrapersonal and interpersonal intelligences. The term religiosity refers to degrees of religious behaviour, belief, or spirituality. The measurement of religiosity is hampered by the difficulties involved in defining what is meant by the term. Numerous studies have explored the different components of religiosity, with most finding some distinction between religious beliefs/ doctrine, religious practice, and spirituality. Studies can measure religious practice by counting attendance at religious services, religious beliefs/ doctrine by asking a few doctrinal questions, while spirituality can be measured by asking respondents about their sense of oneness with the divine or through detailed standardized measurements. When religiosity is measured, it is important to specify which aspects of religiosity are referred to. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Religiosity and intelligence」の詳細全文を読む スポンサード リンク
