study examined the extent to which religious orientation and behavior were related to self-reported EI in 148 church-attending adult Christians. (Non-religious individuals were not part of the study.) The study found that the individuals' self-reported religious orientation was positively correlated with their perceiving themselves to have greater EI. While the number of religious group activities was positively associated with perceived EI, the number of years of church attendance was unrelated. Significant positive correlations were also found between level of religious commitment and perceived EI. Thus, the Christian volunteers were more likely to consider themselves emotionally intelligent if they spent more time in group activities and had more commitment to their beliefs. Tischler, Biberman and McKeage warn that there is still ambiguity in the above concepts. In their 2002 article, entitled "Linking emotional intelligence, spirituality and workplace performance: Definitions, models and ideas for research", they reviewed literature on both EI and various aspect of spirituality. They found that both EI and spirituality appear to lead to similar attitudes, behaviors and skills, and that there often seems to be confusion, intersection and linking between the two constructs. Recently, Łowicki and Zajenkowski investigated the potential associations between various aspects of religious belief and ability and trait EI. In their first study they found that ability EI was positively correlated with general level of belief in God or a higher power. Their next study, conducted among Polish Christians, replicated the previous result and revealed that both trait and ability EI were negatively related to extrinsic religious orientation and negative religious coping. Studies exploring religiosity and educational attainment The relationship between the level of religiosity and one's level of education has been a philosophical, as well as a scientific and political concern since the second half of the 20th century. The parameters in this field are slightly different compared to those brought forward above: if the "level of religiosity" remains a concept which is difficult to determine scientifically, on the contrary, the "level of education" is, indeed, easy to compile, official data on this topic being publicly accessible to anyone in most countries. Different studies available show contrasting conclusions. An analysis of World Values Survey data showed that in most countries, there is no significant relationship between education and religious attendance, with some differences between "Western" countries and former socialist countries, which the authors attribute to historical, political, and economic factors, not intelligence.
