This book takes a social psychological perspective to study the ways in which identity, religious beliefs and well-being are related to and affect each other in the contemporary world. It simultaneously draws upon intellectual resources from the extant interdisciplinary literature to build connections within the broader societal context. In view of the social diversity and changes in post-globalization India, issues of identity, religion and well-being emerge as dynamic and vibrant aspects of social reality in both individual and group contexts, across age groups and genders. The current social-cultural-political scenario in the India, therefore, points to the need to investigate the outcome of personal and social well-being in relation to identity and religion. As contexts change, these issues take different shades and influence human conditions differentially. This book undertakes the investigation by going beyond the traditional tropes of behavioral science and discussing the dynamic interplay and confluence of socio-cultural-political variables in changing times. It draws from a large sample from the four major religious faiths in India-Hinduism, Islam, Christianity and Sikhism-and enables readers to understand significant interactions among facets of identity (personal and social), religious beliefs and practices and well-being (personal and social) with age and gender in an important segment of the global population.
