The Demon-Haunted World book club questions

1. 1.

   Sagan distinguishes scientific skepticism from closed-mindedness. Where in your own thinking do you confuse the two?

2. 2.

   Pick a belief you hold that you have not seriously tried to falsify. What evidence would change your mind — and have you actually looked for it?

3. 3.

   The 'baloney detection kit' includes watching for appeals to authority. Which authorities do you trust without checking, and what would it take to update that trust?

4. 4.

   Sagan argues that pseudoscience fills a genuine human need. What needs — comfort, community, meaning — do you think it meets that science does not obviously provide?

5. 5.

   He worries that a scientifically illiterate public cannot maintain a democracy. Do you think that fear has proven well-founded in the decades since 1995?

6. 6.

   Alien abduction reports, recovered memories, and Satanic panic were the specific pseudosciences Sagan targeted. What are the equivalent belief systems generating similar damage today?

7. 7.

   Sagan is openly emotional about science — he describes his childhood wonder at libraries and the cosmos. Does that emotional register make his skeptical argument more or less persuasive to you?

8. 8.

   The book argues that the universe revealed by science is stranger and more awe-inspiring than myth. Do you find that compelling, or does it feel like a consolation prize?

9. 9.

   Where in your professional life do you accept claims without demanding the level of evidence Sagan would require? Is that a problem or a reasonable trade-off?

10. 10.

    Sagan was writing as he was terminally ill. Does knowing that context change how you read his urgency and his affection for human potential?

11. 11.

    He dedicates substantial space to the history of witch trials, treating them not as evidence of evil but as evidence of mass credulity under social pressure. What modern parallels come to mind?

12. 12.

    Sagan praises science's self-correcting nature. Can you think of an example where science corrected itself slowly and painfully rather than cleanly? What does that say about the argument?

How to run the discussion

• Pick six to eight, not all of them. An hour of real discussion covers fewer questions than anyone expects, and racing the list is what makes a book club feel like homework.
• Open with what people noticed, not what they concluded. Asking for a verdict first hardens opinions before anyone has heard each other.
• Let the disagreement run. The questions below that split a room are the ones worth the time; the ones everyone answers the same way can be skipped.
• Ask the quiet person a specific question. A direct, narrow question is far easier to answer than an open invitation to contribute.
