Sometimes there is no way to know certain aspects about a person’s character without putting them in an unlikely scenario.
For example, you might want to know: “What would the new mailroom clerk do if a dinosaur was rampaging in the hallway?”
Sadly, there is no easy way to determine the answer to this question. And if there was, it would probably get you arrested.
An organization can set up unusual scenarios for testing the mettle of an individual.
This could have many uses:
Employee hiring: “Is the new job candidate a stand-up individual who would help a stranded motorist change a tire, or would they drive on while cackling maniacally?”
Dating: “Would my date attempt to save me from a killer clown, or would they run the other way without even glancing over their shoulder?”
National security: “Would the new agent betray the country for a huge sack of money with a dollar sign on it?”
CONS: None come to mind.
