Religious individuals tend to be happier on average due to two main reasons: spiritual beliefs about the afterlife and a higher power, and religious behaviors such as rituals, social interactions, and acts of kindness. The correlation between religion and happiness is fully mediated by these religious behaviors, rather than religious beliefs. This implies that any cultural institution that promotes social connectedness, acts of kindness, and being present can potentially increase happiness. Religious institutions, with their emphasis on these behaviors, are particularly effective in promoting happiness.
