Etymology
The term 'self-selection' is a modern compound built from core Germanic and Latinate elements. The first element, 'self', is a fundamental concept from Proto-Germanic, retaining its ancient sense of one's own person or identity. It combines with 'select', from Latin 'seligere', which literally meant "to choose apart" or "to single out". The suffix '-ion', also of Latin origin, nominalizes the action. Thus, the word's literal construction—"the action of choosing by oneself"—maps directly and logically onto its modern sociological and methodological meanings, where it describes a process where individual choice, rather than external assignment, determines inclusion, thereby potentially introducing bias into a sample or group.
