Chapter 9 Summary

Content Warning: This chapter addresses the topics of rape and childhood sexual abuse.

Sagan discusses John Mack, a Harvard university psychiatrist he has “known for many years” (153). Mack was originally skeptical of alien abductees, but now accepts their accounts at face value. Therapists who accept such accounts uncritically are denying the more rational possibility that the "recovered" memories they are recounting are more likely vestiges of more prosaic repressed incidents, particularly of rape and childhood sexual abuse. Recent trends in therapeutic treatment are focused on accepting the claims of patients; not believing them—whether they claim alien abduction or sexual abuse—is considered harmful to patients and to their relationships with their therapists. While he can appreciate the humaneness of this approach, Sagan suggests that it creates a lot of false data and reinforces false beliefs in patients, including several instances of false accusations of childhood sexual abuse.

As a case study in the willingness to believe in therapeutically recovered memories, Sagan turns to accusations of sexual abuse involving satanic ritual cults. According to a 1994 study at the University of California, 12,000 claims of sexual abuse at the hands of satanic cultists were evaluated—an episode of cultural history we now know as the Satanic Panic—and none were found to have merit, leading scholars to conclude that the most common cause of cult-related memories is a “mutual deception between the patient and the therapist” (161). Sagan uses the case of Paul Ingram “a man who may have had his life ruined because he was too gullible, too suggestible, too unpracticed in skepticism” (161), to depict the consequences of such recovered memories. In 1988, Ingram was Chairman of the Republican Party in Olympia, Washington; he was a well-regarded and very religious person in the community until his daughter, after a “highly emotional session” (162) at a religious retreat, accused him of sexually assaulting, torturing, and impregnating her and making her sexually available to sheriff’s deputies. Ingram had no memory of these events, but when police investigators, church officials, and a consulting psychologist explained that offenders can repress memories of their actions, Ingram admitted guilt, and later concocted several other false memories using the “memory recovery” techniques he was taught. Though none of the allegations were ever substantiated, Ingram pled guilty to six counts of rape and was sentenced to 20 years in prison.

Sagan notes that Ingram’s case, alien abductions, and therapeutically recovered memories of childhood sexual abuse share one thing in common: a specialist therapist, whose livelihood depends on eliciting certain memories or emotions, and who is thus unlikely to apply rigorous skepticism to the results of their work. This creates a closed system of knowledge which rewards believers, confirms tenuous beliefs, and abhors skeptical thinking.

Chapter 10 Summary

Sagan proposes a thought experiment: A friend claims to have a fire-breathing dragon living in his garage. When asked to display the creature, however, the friend claims that it is invisible, its fire-breath can’t be detected by heat registers, etc. In short, the friend is asking that his word be taken as sole proof of the dragon’s existence. Since it cannot stand tests of falsifiability, the anecdotal proof is useless. The validity of science rests on outside confirmation and the ability of others to replicate proofs on their own. While this is relatively straightforward for experimental science, Sagan admits it is trickier with intellectual claims that offer no physical evidence.

Sagan recounts the story of Kirk Allen, a brilliant physicist from the Manhattan Project, who claimed to be able to remember a future life filled with adventure. Allen’s psychoanalyst Robert Linder became so enraptured with Allen’s stories that he came to believe them himself. Even after Allen admitted to making it all up, Linder had trouble coming to terms with the truth. Sagan argues that the same is true of John Mack. Examining some of the proofs Mack has accepted, such as scars called “scoop marks” (182), Sagan points out that the scars offer no concrete proof of aliens, and could have been caused by any number of rational occurrences. Sagan laments that this has seemingly never occurred to Mack. Sagan suggests that Mack’s case raises the question of how to most effectively “teach critical thinking more broadly and more deeply in society” (184), a question The Demon-Haunted World tries to answer.

Chapter 11 Summary

On March 7, 1993, Parade magazine printed an article by Sagan which was a short summary of the argument he has made over the previous ten chapters: Since anecdotal evidence can be explained in simpler terms—such as mass hallucination or faulty therapeutic practice—and there is no physical evidence of extraterrestrial visitors, it is very unlikely contemporary beliefs in UFO phenomena are accurate. Given Sagan’s fame as an astronomer and science communicator, the article was broadly read and received a voluminous response. While Sagan admits that the article was “widely misunderstood” (191), the passion of the responders struck him, and realizes how much agony comes with the experience that is now interpreted as alien abduction, whatever its true nature may be. Without commenting on any letters in particular, Sagan includes extracts from 43 letters which represent a wide range of perspectives on the phenomena Sagan examines; in them, many who claim to be experiencers take umbrage at his assertion that mass hallucination is responsible for stories of alien abductions.

Chapters 9-11 Analysis

Sagan concludes the main arc of his argument, introducing the foundations that underlie critical thinking: the skeptical approach and trust in the scientific method. In Chapters 9 and 10, Sagan’s primary purpose is to underscore why we cannot accept anecdotes as evidence. He explains how therapists can draw out these stories, and believe them themselves, if they are not employing the critical thinking that would allow them to recognize their impossibility. The case study of Paul Ingram during the Satanic Panic shows how uncritical submission to psychological authority lends validity to outlandish beliefs, and the very real consequences that follow.

As an antidote to the unthinking acceptance of unlikely claims, Sagan suggests the Dragon in the Garage, a parable that introduces the concept of falsifiability and describes the patience required in gathering data and examining evidence. Skeptical scrutiny and patience for evidence define the discipline of critical thinking, so for this reason, Sagan introduces them before the rest of his toolkit, which appears in the following chapter. Sagan concludes not by denying the existence of alien abductions, but by invoking Occam’s Razor, which states that the simplest explanation for phenomena is usually the correct solution: There is no verifiable hard evidence for abductions and there are simpler explanations for the phenomena described by experiencers. Occam’s Razor is yet another part of Sagan’s Baloney Detection Kit.

Although Sagan holds up John Mack as a negative example of many of the faults the book addresses, he doesn’t blame him for his very human folly. While Mack’s claims in the realm of alien abduction may appear benign, Sagan contextualizes the seriousness of Mack’s folly with Paul Ingram and the Satanic Panic, in which very serious consequences arose from a psychologist not practicing critical thinking. Sagan’s analysis of Mack essentially bookends his Dragon in the Garage metaphor, suggesting that Mack’s primary flaw is his inability to recognize falsifiable claims and his want to satisfy his own personal hypothesis.

The letters Sagan includes provide a set of raw data for the reader, giving a cross-section of reported beliefs, and suggesting the impossibility of codifying such accounts. Sagan refrains from commenting on them directly, allowing readers to form their own opinions free from his bias. This is one of many instances in which Sagan trusts his readers to employ the method he is promoting. Several of the letters included have a particular take on the concept of abduction: Jesus Christ is responsible. The intermingling of a widespread belief system with these more marginalized reports points to the realm in which both are based: the human need for belief.
