Incest Taboo 21 Lindsey Allen Fa -

Finnish anthropologist Edvard Westernarck (1891) proposed that individuals raised in close domestic proximity during early childhood (typically the first 2–6 years) develop a mutual sexual aversion. This psychological mechanism, now supported by studies of Israeli kibbutzim and Chinese shim-pua marriages, reduces the likelihood of inbreeding and its associated genetic costs (Wolf, 1995). However, the Westernarck effect explains aversion, not the taboo as a cultural rule.

Modern evolutionary psychology integrates these views: humans have an innate inbreeding avoidance mechanism (proximate cause), but culture codifies and extends it to ensure exogamy, which increases genetic diversity and social cooperation (ultimate cause). For example, the taboo often includes step-kin and in-laws, where no genetic risk exists—showing cultural overgeneralization.

Lindsey Allen Fa’s "Incest Taboo 21" confronts a culturally charged subject—incest taboos—through contemporary theoretical lenses and creative framing. The piece interrogates how legal, moral, psychological, and anthropological discourses intersect with lived experience and representation. My central claim: Fa reframes the incest taboo not merely as a prohibitive norm but as a site where power, biopolitics, narrative authority, and cultural memory converge, producing both social protection and mechanisms of silence and shame.

  • Legal specificity

    • Few prohibitions evoke as consistent a response across cultures as the incest taboo. From the Trobriand Islanders studied by Malinowski (1927) to contemporary Western societies, sexual relations between close kin—especially parents and children, and siblings—are nearly universally condemned. Yet the taboo is not a simple biological reflex; it varies in strictness, scope, and punishment. This paper explores why the incest taboo exists and how it functions. As Lindsey Allen notes
