The 90% Shock Test

I made this quiz in Involve.Me with content from Annie Duke’s book How To Decide: Simple Tools for Making Better Choices. The final questions are her “Shock Test” where you answer 10 questions with numerical answers with your best bull’s eye estimate, a lower bound and an upper bound. Your goal is to set the bounds as narrowly as possible, but still be include the correct answer in 9/10 of the questions. It’s a really interesting exercise in decision making with incomplete information.
