Personality-based integrity tests indirectly estimate job applicants' honesty by measuring psychological traits such as dependability and conscientiousness. For example, prison inmates serving time for white-collar crimes (counterfeiting, embezzlement, and fraud) scored much lower than a comparison group of middle level managers on scales measuring reliability, dependability, honesty, conscientiousness, and abiding by rules. These results show that companies can selectively hire and promote people who will be more ethical. For more on integrity testing, see the "what Really Works" feature in this chapter.
