The complexity of today's religious landscape may be attributed to the increasingly à la carte approach to spirituality, where individuals pick and choose beliefs that resonate with them, rather than adhering to the fixed menu of traditional organized religions. This trend is acknowledged by some organized religions, such as Unitarian Universalism, which seek to accommodate a wide range of spiritual perspectives, including those of individuals who might otherwise identify as atheists. Consequently, those who classify themselves as "nones," signifying no affiliation with organized religions, might still engage in spiritual practices, thereby crafting their unique forms of spirituality outside conventional religious frameworks. This indicates that the "nones" are not a uniform group but rather a collection of individuals each with their own micro-religions.

This concept finds a parallel in Japan, where a significant portion of the population identifies as non-religious yet actively participates in celebrations and rituals derived from various world religions, albeit in a secular context. This juxtaposition highlights the fluid and personalized nature of spirituality today, suggesting that religious identity and practice are far more nuanced and individualized than traditional classifications might suggest.
