Summary

Chapter 6 presents Cotton Mather as a ghost-hunting television personality. Through a mock reality show script, Petri portrays Mather touring New England with his “Falem Body Inspector” crew, collecting spectral evidence to “prove” witchcraft. The episode features a farmer whose family believes their neighbor is a witch after a toad-in-the-blanket incident and subsequent lameness in their children. Mather and his expert, Learned Doctor, examine bodies for Satan’s amulets, interview children who display classic bewitched behavior (vomiting nails, refusing the Bible, riding invisible horses), and attribute ordinary accidents—like a broken cart window and subsequent lice—to sorcery. The chapter ends with Mather solemnly reporting that his team has never encountered a case that was not witchcraft. Petri’s footnotes confirm that all anecdotal examples (such as riding an invisible horse) are historically documented.

Key Events

  1. Introduction of the Mather family – Cotton Mather, accompanied by his father Increase (who reluctantly appears), presents himself as an expert on the paranormal.
  2. Arrival at a New England farm – A farmer requests Cotton’s help to confirm if their neighbor is a witch; the farmer wants “rigorous expertise” before proceeding.
  3. The toad-in-the-blanket incident – The farmer’s wife explains how hanging the child’s blanket revealed a toad, which when thrown into fire popped and vanished; the accused neighbor was later found scorched.
  4. Children’s ailments – The farmer reports both children are lame on sides that vary; Mather interviews them, observing them pretend to vomit coins and nails and refuse to read the Bible.
  5. Cotton’s earlier case – Mather recounts a girl who disliked Increase Mather's book, later ate an apple, laughed at jest books, and “rode up the stairs on an invisible horse.”
  6. Learned Doctor’s evidence – Another accused woman broke a window by yelling; afterward, the cart that struck the window kept getting stuck at gates, and her other victim suffered excessive lice.
  7. Final verdict – Cotton Mather announces to a gathering of somber men that the week’s investigation confirms witchcraft; asked if they ever found a non-witch case, he answers no.

Character Development

  • Cotton Mather – Portrayed as a self-aggrandizing, theatrical fraud who presents cherry-picked, supernatural explanations for mundane events. His “development” is a deepening commitment to his grift.
  • Learned Doctor (F.B.I. – Falem Body Inspector) – A parody of the forensic “expert” who performs invasive body searches for witch's teats and enthusiastically cites the Malleus Maleficarum.
  • The Farmer and His Wife – Ordinary Puritan townsfolk who want “proof” before condemning a neighbor; they are credulous and complicit, yet nervous enough to seek validation.
  • The Accused Neighbor (offscreen) – Never named or given voice; she remains a silent victim whose property is violated and body examined without consent.

Themes, Symbols, or Motifs

  • Spectral Evidence and Confirmation Bias – Mather interprets every coincidence (toads, lameness, lice, stuck carts) as proof of witchcraft, never considering alternative explanations.
  • Gender and Power – The chapter repeatedly notes that “most witches are women”; women’s bodies are subject to invasive inspections, while men serve as judges and accusers.
  • Theatricality and Modern Media – The mockumentary format (b-roll, reenactments, voice-over) highlights how witch-hunts resemble modern reality TV’s search for “paranormal” activity.
  • Religious Authority Misused – Cotton weaponizes his Puritan credentials (and his father’s books) to lend legitimacy to absurd methods.

Why This Chapter Matters

Petri uses satire to expose the logic (or lack thereof) behind the Salem witch trials and earlier New England panics. By framing the narrative as a ghost-hunting show, she underscores the performative nature of accusations and the way authority figures can manufacture “evidence” to justify persecution. The chapter also serves as a cautionary tale about confirmation bias and the dangers of deferring to self-proclaimed experts. In the broader context of Alexandra Petri’s US History, this chapter lampoons the Puritan impulse to find supernatural causes for ordinary misfortunes—a pattern that repeats throughout American history.

Study Questions & Answers

1. How does Petri’s mockumentary format critique historical witch trials?
The format mimics modern paranormal reality TV, where “experts” use dubious methods to convince audiences of supernatural events. Petri draws a parallel between Cotton Mather’s theatrical displays and the ways contemporary media can manufacture fear and scapegoating.

2. What role does the “Learned Doctor” play in reinforcing Mather’s authority?
He functions as a parody of forensic expertise. His elaborate body searches and citation of the Malleus Maleficarum create an illusion of scientific rigor, convincing townspeople that the accusations are based on “hard evidence.”

3. Why does Cotton Mather claim he has never found a non-witch case?
The statement reveals the fundamental flaw in his inquiry: he begins with the assumption that witchcraft exists and then interprets all evidence to confirm that assumption. This circular reasoning makes disconfirmation impossible, a classic pattern in moral panics.
