The Oxford English Dictionary defines religiosity as: "Religiousness; religious feeling or belief. [...] Affected or excessive religiousness". Different scholars have seen this concept as broadly about religious orientations and degrees of involvement or commitment. The contrast between "religious" and "religiose" (superficially religious) and the concept of "strengthening" faith suggest differences in the intensity of religiosity. Scholars attempt to measure religiosity at the levels of individuals or groups, but differ as to what behaviors constitutes religiosity. Sociologists of religion have observed that an individual's experience, beliefs, sense of belonging, and general behavior often are not congruent with their religious behavior, since there is much diversity in how one can be religious or not. Problems arise in measuring religiosity. For instance, measures of variables such as church attendance produce different results when different methods are used, such as traditional surveys as opposed to time-use surveys.
Components The measurement of religiosity is hampered by the difficulties involved in defining what is meant by the term and what components it includes. Numerous studies have explored the different components of religiosity, with most finding some distinction between religious beliefs/doctrine, religious practice, and spirituality. When religiosity is measured, it is important to specify which aspects of religiosity are being discussed. Numerous studies have explored the different components of human religiosity. What most have found (often using factor analysis) is that there are multiple dimensions. For instance, Marie Cornwall and colleagues identify six dimensions of religiosity based on the understanding that there are at least three components to religious behavior: knowing (cognition in the mind), feeling (effect to the spirit), and doing (behavior of the body). For each of these components of religiosity, there were two cross classifications, resulting in the six dimensions:
Cognition traditional orthodoxy particularistic orthodoxy Affect Palpable Tangible Behavior religious behavior religious participation Sociologists have differed over the exact number of components of religiosity. Charles Glock's five-dimensional approach (Glock, 1972: 39) was among the first of its kind in the field of sociology of religion. Other sociologists adapted Glock's list to include additional components (see for example, a six component measure by Mervin F. Verbit). Other researchers have found different dimensions, generally ranging from four to twelve components. What most measures of religiosity find is that there is at least some distinction between religious doctrine, religious practice, and spirituality. Most dimensions of religiosity are correlated, meaning people who often attend church services (practice dimension) are also likely to score highly on the belief and spirituality dimensions. Nonetheless, an individual's scores on a measure of religiosity can vary between dimensions; they may not score high on all dimensions or low on all dimensions. For example, an individual could accept truthfulness of the Bible (belief dimension), but never attend a church or even belong to an organized religion (practice dimension). Another example is an individual who did not accept orthodox Christian doctrines (belief dimension) but did attend a charismatic worship service (practice dimension) in order to develop his/her sense of oneness with the divine (spirituality dimension). A different individual might disavow all doctrines associated with organized religions (belief dimension), not affiliate with an organized religion or attend religious services (practice dimension), and at the same time be strongly committed to a higher power and feel that the connection with that higher power is ultimately relevant (spirituality dimension). These are explanatory examples of the broadest dimensions of religiosity and may not be reflected in specific religiosity measures. Demographic studies often show a wide diversity of religious beliefs, belonging, and practices in both religious and non-religious populations. For instance, among Americans who are not religious and not seeking religion, 68% believe in God, 12% are atheists, 17% are agnostics. Also, 18% self-identify as religious, 37% self-identify as spiritual but not religious, and 42% self-identify as neither spiritual nor religious. Furthermore, 21% pray every day and 24% pray once a month. Global studies on religion also show diversity. Decades of anthropological, sociological, and psychological research have established that the common assumption of "religious congruence" is rarely accurate. "Religious congruence" is the view that religious beliefs and values are tightly integrated in an individual's mind, or that religious practices and behaviors follow directly from religious beliefs, or that religious beliefs are chronologically linear and stable across different contexts. People's religious ideas are fragmented, loosely connected, and context-dependent, like their ideas in all other domains of culture and life. The beliefs, affiliations, and behaviors of any individual are complex activities that have many sources including culture. Mark Chaves gives the following examples of religious incongruence: "Observant Jews may not believe what they say in their Sabbath prayers. Christian ministers may not believe in God. And people who regularly dance for rain don't do it in the dry season."
Difficulties in measurement
Polls and surveys Decades of anthropological, sociological, and psychological research have shown that congruence between an individual's beliefs, attitudes, and behavior concerning religion and irreligion is rare. The reliability of any poll results, in general and specifically on religion, can be questioned due numerous factors such as:
