Why don’t we eat people? (classic)

A question from a four-year-old tips us into an investigation of one of our most fundamental taboos: cannibalism. With help from New Yorker food critic Hannah Goldfield and writer Kelefa Sanneh.

Topics Discussed

Episode Summary

Executive Summary: The episode explores cannibalism as a cultural, legal, and biological taboo through three lenses: a child’s innocent question, historical propaganda from Columbus’s era, and the Foray of Papua New Guinea, whose funerary cannibalism may have spread kuru. The hosts argue taboo is partly learned, partly seemingly universal, and often shaped by power, history, and health risk rather than pure disgust.

Main Topics: A child’s question as the episode’s entry point: Otto, a four-year-old, asks why humans don’t eat human heads, prompting a discussion of curiosity, taboo, and how moral rules are taught to children. Cannibalism as a cultural taboo, not pure instinct: The episode argues that disgust toward cannibalism feels hardwired, but is in fact deeply shaped by culture and upbringing, with parallels to other food customs across societies. Columbus, the Caribs, and the invention of the cannibal image: The show traces how Columbus’s reports about the Caribs helped popularize the modern cannibal stereotype and justify enslavement and colonial violence. European hypocrisy and medical cannibalism: While Europeans accused others of cannibalism, they also consumed mummia—powdered mummy material—as medicine, revealing a double standard in defining ‘civilized’ behavior. Survival cannibalism and moral exceptions: The episode briefly addresses the Donner Party and the Uruguayan rugby team as cases where cannibalism may be understood as survival under extreme conditions, yet remains stigmatized. Armin Meiwes and consent, murder, and revulsion: A modern German cannibalism case raises questions about consent, legal definitions of murder, sexual motive, and whether moral disgust should influence law. The Foray, kuru, and funerary cannibalism: The Foray’s mortuary cannibalism is presented as an act of love and respect that unintentionally spread kuru, linking taboo, ritual, and public health.

Key Arguments: Cannibalism feels like an ultimate taboo because people don’t just follow a rule against it; they often absorb it so deeply they stop remembering it was learned. The meaning of cannibalism is historically contingent: Columbus’s reporting helped attach the label to enemies, making it a political tool for conquest and enslavement. Disgust is culturally transmitted, not purely innate; societies differ in what they find edible, and many cultures have food taboos of their own. Survival cannibalism is a distinct category that people judge differently, showing that context matters in moral evaluation. The German Armin Meiwes case shows how consent alone may not resolve cannibalism’s legal and ethical status, because murder and desecration remain central concerns. The Foray case suggests a taboo can be simultaneously a ritual of love and a health hazard; cannibalism can be both meaningful and dangerous. Lab-grown human meat is used as a thought experiment to test whether the taboo is about harm, disgust, or the symbolic sanctity of the human body.

Data Points: Otto’s age: 4 - The child whose question launches the episode is four years old. Cannibalism-related case timeline: 1493 - Columbus’s second voyage to the New World and the origin point for the modern cannibal stereotype discussed in the episode. Spanish ships on Columbus’s voyage: 17 - Columbus arrived with a fleet of 17 ships on his expedition. European mummy-based medicine period: 11th to 17th century - The episode says mummia consumption persisted in Europe for several centuries. Mummia recipe age: 24 - The recipe cited in London Pharmacopiae specifies a red-headed man age 24 who had been hanged. Armin Meiwes sentence length: about 8 years - His first conviction in Germany was manslaughter with an approximate eight-year sentence. Kuru gender distribution: about 2% adult males - The disease mostly affected children and women; only about 2% of cases were adult males. Kuru incubation period: up to 40 years - The disease could remain latent for decades before symptoms appeared. Kuru survival window after onset: 2 months to 3 years - Once symptoms appear, prognosis ranges from a couple months to as long as three years. Foray population size: tens of thousands - The Foray are described as a group numbering in the tens of thousands.

Pivotal Quotes: "What are the reproductive politics of like Doug Venus is bad?" — Otto: A child’s offhand, confused response during the discussion of whether a fertilized duck egg feels morally different from other foods. "The head of the deceased was placed over a fire to burn off the hair, and then it was defleshed with a bamboo knife." — PJ Vote quoting anthropological research: Describing the Foray funerary cannibalism ritual in Papua New Guinea. "The most anxiety-producing command that you can get in the English language is enjoy." — Calva/quoted attribution: A side conversation during the pastry tasting segment, used to capture the pressure of being told to enjoy something on command.

Implications: The episode suggests food taboos are shaped by history, power, and health as much as by instinct. For listeners, cannibalism becomes a case study in how moral boundaries form, persist, and sometimes mislead.
