What is self-selection in marriage?

Self-selection in marriage often involves factors like personal satisfaction levels, compatibility, and voluntary decisions based on mutual attraction and interests. However, in the context of arranged marriages, "self-selection" can also refer to subtler and less direct processes. For example, in the podcast episode "The Evolutionary Psychology Of Love" from the Modern Wisdom, familiarity plays a crucial role. Here, love and attachment might develop more from being in close proximity and spending time together rather than from initial romantic attraction. This can happen even when individuals do not choose their partners themselves but grow to develop feelings over time through continuous interaction and shared experiences 1.
