Chapter 30: Quiz
1. Chronotype research shows that waking early is: - A) Essential for success - B) Partially genetically determined (~50% heritable); forcing night owls to wake at 5am produces sleep deprivation, not productivity - C) The most important factor in health - D) Controllable through willpower alone
Answer: B. Chronotype is partially genetic. The optimal wake time is the one that allows 7–9 hours of sleep, not an arbitrary 5am.
2. The strongest evidence from the morning stack belongs to: - A) Cold showers - B) Meditation - C) Exercise — with medium-to-large effect sizes for mood, cognition, energy, and health across hundreds of meta-analyses - D) Journaling
Answer: C. Exercise has by far the strongest evidence of any lifestyle intervention.
3. Cold shower evidence is best described as: - A) Strong and conclusive - B) Modest at best — one RCT found reduced self-reported sick days, but mood and energy claims outpace the evidence - C) Completely debunked - D) Supported by multiple large-scale RCTs
Answer: B. Some evidence exists but it's modest, largely self-reported, and not blinded. The claims go well beyond the data.
4. Meditation adverse effects occur in approximately what percentage of practitioners? - A) 0% - B) 8% — including increased anxiety, depersonalization, and in rare cases psychotic episodes - C) 50% - D) Only during retreats
Answer: B. Britton and colleagues found ~8% experience significant adverse effects. This is rarely discussed in meditation marketing.
5. Pennebaker's expressive writing evidence supports: - A) All forms of journaling - B) Writing about emotional experiences for 15–20 minutes, 3–4 days — specifically for processing difficult events - C) Gratitude journaling as the most effective form - D) Guided journals costing $30+
Answer: B. The evidence is specifically for expressive writing about difficult experiences, not for general journaling practices.
6. The evidence-based morning requires exactly: - A) A 7-component optimized stack - B) Three things: adequate sleep (7–9 hours), regular exercise (any time), and reduced phone use in the first hour - C) Waking at exactly 5am - D) Cold showers and meditation minimum
Answer: B. Sleep, exercise, and phone management have evidence. Everything else is optional or unsupported.
7. The "optimization cult" becomes problematic when: - A) It produces anxiety about imperfection, mistakes the routine for the outcome, creates performance identity, and ignores structural reality - B) It includes exercise - C) People enjoy their routines - D) It's practiced by successful people
Answer: A. Optimization crosses from helpful to harmful when it produces more anxiety than productivity and becomes an end rather than a means.
8. The claim that exercise improves mood has an effect size comparable to: - A) Homeopathy - B) Medication for moderate depression (d ≈ 0.50–0.80) - C) A placebo - D) Nothing
Answer: B. Exercise has effect sizes comparable to antidepressant medication for moderate depression — one of the strongest findings in behavioral health.
9. Why is "just exercise" less marketable than a 7-component morning routine? - A) Exercise doesn't work - B) A single recommendation can't fill a YouTube video, a course, or a book — the morning routine industry requires complexity to sustain content and revenue - C) Exercise is too expensive - D) Nobody knows about exercise
Answer: B. The content and product ecosystem around productivity requires complexity. "Exercise regularly" is too simple to sustain an industry.
10. The chapter's overall message about morning routines is: - A) Everyone needs a 7-component morning routine - B) Morning routines are useless - C) Sleep and exercise have strong evidence; everything else in the standard morning stack has modest or no evidence; and the optimization culture itself can become counterproductive - D) Only successful people can benefit from routines
Answer: C. The evidence supports simplicity (sleep + exercise + phone management), not complexity. The optimization culture can produce more anxiety than productivity.
