Summary: This segment from the Today Show explores whether humans are “wired”—or, biologically predisposed—to cheat on their mates. The clip can be used to teach biological determinist perspectives of gender, and specifically those rooted in sociobiology. In short, biological determinism argues that the social world is predetermined by biological factors. Sociobiology stems from this tradition of thought, but focuses more specifically on genetic reproduction and evolutionary processes. Often relying on observations of animal behaviors to make claims about human behaviors, sociobiology argues that a fundamental human drive is to ensure genetic reproduction, and many human activities can be reduced to this drive. Using the case of infidelity, this video clip is helpful for shedding light on sociobiological explanations of gender difference. The segment opens with a sociobiological perspective, using Barash and Lipton's (2001) book The Myth of Monogamy as a point of reference. Here, the authors argue that monogamy is not natural; from an evolutionary standpoint, humans have a stake in having multiple sexual partners. Sexual promiscuity is prevalent throughout the animal kingdom, they argue, and humans are not exempt from the same biological urges that drive other animals to be promiscuous. After the opening segment (minute mark 2:17), host Meredith Vieira speaks with Jeffrey Kluger, TIME magazine’s science editor, and psychologist David Buss; the conversation quickly turns to a discussion of gender difference. Kluger represents a fairly classical sociobiological argument when he states: “Nature wants one thing, and what it wants are babies. It also wants lots of them. And it wants variety, because the greater the genetic variety, the greater the likelihood that the babies are going to survive into adulthood and do well.” Kruger goes on to assert that men will look for women who are young and fertile, and women look for men who are good providers, such as those who are rich and powerful. Buss introduces more socio-cultural elements into the discussion, such as strong social norms against cheating, and argues that both men and women feel attraction to others outside of their relationships. He also points to psychological pathologies, namely narcissism, as an explanation for infidelity, and draws attention to infidelity in a cross-cultural context where polygamy is common (that is, cultures where men are legally entitled to have multiple wives). Although Buss mostly draws upon socio-cultural explanations, he also suggests that biological impulses to be non-monogamous are a part of our “human nature.” Asked why men cheat more, Kruger draws upon biological and sociological arguments, arguing that: (1) biologically, men have the ability to breed more, and could conceivably breed offspring everyday; from this he argues that men are “tripwired" for infidelity; and (2) in a patriarchal society such as ours, men are more likely to be in positions of power and feeling entitled to be unfaithful. After screening the video, viewers can be encouraged to identify messages in the clip that cohere with, and deviate from, the sociobiological perspective. Viewers can also be encouraged to explore feminist and/or sociological critiques of biological determinism, such as those outlined in Carmen Schifellite’s (1987) essay, "Beyond Tarzan and Jane Genes: Towards a Critique of Biological Determinism.”
