This seems like a ridiculously transparent move. If I knew no psychological theory whatsoever, it would still be obvious that "What do you think the percentage of employees who have stolen from their job is?" is a question primarily designed to test how likely I am to steal (and also possibly testing how likely I am to trust other employees at my future job).

I would try to figure out the lowest number I can write down without it being obvious that it's the lowest number I can write down. Of course I am still going off of my experience here to estimate what sort of numbers are low. But at that point you are rewarding people for being good at lying.
