About This MicroSim¶
Every chapter of Gut Check grades popular claims with the Hype Meter: Strong (consistent evidence in people), Moderate (some human evidence, or a solid link whose cause is unclear), Preliminary (small, early, short, or mostly animal studies), or Hype (a popular claim the evidence does not support).
This MicroSim puts all of that practice in one place. It deals out 16 claim cards drawn from Chapters 1 to 18, such as "70% of your immune system lives in your gut" and "Implanted vagus nerve stimulation is FDA approved for treatment-resistant depression." You grade each card. Then the sim shows the book's grade, a one-sentence reason based on the studies in that chapter, and whether your grade was a match, too generous (closer to Strong than the evidence supports), or too harsh.
The tally at the bottom counts your matches and your misses in each direction. Good scientists aren't just skeptical. They're calibrated: they believe strong evidence and doubt weak evidence.
How to Use¶
- Read the claim on the card. Notice the exact wording. The book grades the claim as stated.
- Ask the six questions from the Hype Meter: mouse or human, correlation or cause, how many, how long, who paid, and is something being sold.
- Click Strong, Moderate, Preliminary, or Hype in the control area.
- Read the book's grade and reason. If you missed, decide which evidence feature you overlooked.
- Click Next card. Check Show chapter if you want a hint about where the claim came from.
- After all 16 cards, read your summary. Click Start over to reshuffle and try again.
Learning Objective¶
Bloom level: Evaluate. The learner will evaluate popular gut-brain claims by assigning a Hype Meter grade based on the kind and amount of evidence, and will judge whether their own grading leans too generous or too harsh.

Lesson Plan¶
Grade level: 9 to 12 (biology, health science, AP Psychology, or a science club)
Duration: 25 to 35 minutes
Activity:
- Warm-up (5 minutes). Show one card ("Your gut has more neurons than your brain") and ask students to vote by hand on a grade. Discuss what they would need to know to decide.
- Sort solo (10 minutes). Each student sorts all 16 cards without the chapter hint and writes down their final score and their "too generous" and "too harsh" counts.
- Pair and argue (8 minutes). Partners pick the two cards they missed most and use the chapter reasons to explain the book's grade to each other.
- Whole-class debrief (7 minutes). Collect class totals for "too generous" versus "too harsh." Ask: which way does our class lean, and why might social media push people that way?
- Limits (5 minutes). Read the "What this model leaves out" box in Chapter 20 and discuss why real grading is less tidy than four buttons.
Assessment questions:
- "The gut holds about 70% of the body's antibody-making plasma cells." Why does this true fact not support the claim that 70% of the immune system is in the gut?
- Two cards involve vagus nerve stimulation. Why does one earn Strong and the other Preliminary?
- Pick one Preliminary card. Describe a study that could move it up to Moderate.
- Explain the difference between being skeptical and being calibrated.
