By applying the device of imaginary results, find your own strength of belief in any three of the following propositions: (1) Julius Caesar is a real historical person (i.e. not a myth invented by later writers); (2) Achilles is a real historical person; (3) the Earth is more than a million years old; (4) dinosaurs did not die out; they are still living in remote places; (5) owls can see in total darkness; (6) the configuration of the planets influences our destiny; (7) automobile seat belts do more harm than good; (8) high interest rates combat inflation; (9) high interest rates cause inflation. Hint: Try to imagine a situation in which the proposition H₀ being tested, and a single alternative H1, would be the only possibilities, and you receive new data D consistent with H₀: P(D|H₀) 1. The imaginary alternative and data are to be such that you can calculate the probability P(D|H₁). Always use an H0 that you are inclined not to believe; if the proposition as stated seems highly plausible to you, then for H0 choose its denial.
