Quiz questions
Question 1
What does the book define as the "certainty illusion"?
- The tendency to overestimate how much we know and to favor simple, confident answers over nuanced uncertainty
- A philosophical claim that absolute certainty is logically impossible
- The idea that science will eventually produce a single unified theory of everything
- A media strategy of presenting fictional stories as factual to gain attention
Question 2
Which combination best explains why people prefer certainty, according to the book?
- Because uncertainty always leads to worse decisions
- Because cognitive biases like confirmation bias and the need for closure make certainty emotionally and socially rewarding
- Because humans are biologically incapable of probabilistic thought
- Because institutions force people to adopt certainty through laws
Question 3
How does the book characterize the scientific process?
- As iterative, provisional, and self-correcting rather than a march toward absolute truth
- As a linear progression that steadily uncovers final, unchanging facts
- As primarily a method for proving hypotheses beyond doubt
- As an opinion-driven enterprise with no corrective mechanisms
Question 4
Which statement best captures the chapter on the limits of evidence?
- Evidence is constrained by measurement error, confounding, incomplete data, and the gap between correlation and causation
- All well-conducted studies provide definitive causal answers
- If experts disagree, one side must be wrong because evidence is always decisive
- Statistical significance (p<0.05) is sufficient to prove real-world effects
Question 5
According to the book, which approach improves decision-making under uncertainty?
- Waiting for absolute proof before taking action
- Using probabilistic thinking, adaptive policies, structured decision procedures, and epistemic humility
- Relying solely on confident experts and majority opinion
- Favoring simple narratives and decisive action regardless of evidence
