deviate from religious teaching, and in some instances shunning by family members. Some religious organizations permit the censure of critics. Across societies, individuals and communities can be socially excluded on the basis of their religious beliefs. Social hostility against religious minorities and communal violence occur in areas where governments do not have policies restricting the religious practise of minorities. A study by the Pew Research Center on international religious freedom found that 61% of countries have social hostilities that tend to target religious minorities. The five highest social hostility scores were for Pakistan, India, Sri Lanka, Iraq, and Bangladesh. In 2015, Pew published that social hostilities declined in 2013, but harassment of Jews increased. Consequences Health In gay men, results of psycho-emotional damage from marginalization from a heteronormative society include suicide and drug addiction. Scientists have been studying the impact of racism on health. Amani Nuru-Jeter, a social epidemiologist at the University of California, Berkeley and other doctors have been hypothesizing that exposure to chronic stress may be one way racism contributes to health disparities between racial groups. Arline Geronimus, a research professor at the University of Michigan Institute for Social Research and a professor at the School of Public Health, and her colleagues found that psychosocial stress associated with living in extreme poverty can cause early onset of age-related diseases. The 2015 study titled, "Race-Ethnicity, Poverty, Urban Stressors, and Telomere Length in a Detroit Community-based Sample" was conducted in order to determine the impact of living conditions on health and was performed by a multi-university team of social scientists, cellular biologists and community partners, including the Healthy Environments Partnership (HEP) to measure the telomere length of poor and moderate-income people of White, African-American and Mexican race. In 2006, there was research focused on possible connections between exclusion and brain function. Studies published by both the University of Georgia and San Diego State University found that exclusion can lead to diminished brain functioning and poor decision making. Such studies corroborate with earlier beliefs of sociologists. The effect of social exclusion have been hypothesized in various past research studies to correlate with such things as substance abuse and addiction, and crime. Economics The problem of social exclusion is usually tied to that of equal opportunity, as some people are more subject to such exclusion than others. Marginalisation of certain groups is a problem in many economically more developed countries where the
