Ole Harry is the skipper of the Better Late Than Never, a VERY slow freighter that runs from Singapore to Los Angeles and back without making any other stops. The boredom of the voyage results in high worker turnover. He therefore has two kinds of crew members: short-term workers who lose their patience with the long, boring trip and long-term workers who are very patient and will stick with the job. Short-term workers are necessary but contribute little to the profitability of the ship. Long-term workers are highly valuable, and Ole Harry pays them a much higher wage. As a result, all new applicants tell Ole Harry that they will be long-term workers, regardless of whether they really are patient or not.
What can Ole Harry do to screen his applicants into the right jobs: that is, truly patient workers to long-term crew and truly impatient workers to short-term crew?
A. Ask job applicants to stand on one foot for 10 minutes.
B. Ask job applicants to sort his 1,500-card baseball card collection by batting average.
C. Ask job applicants to sign a pledge stating "I fully intend on remaining on board for five years."
D. Strand job applicants on a desert island, return after several months, and if they're still alive they are hired.
