The term 'propensity to become dishonest' can be summarized as having a tendency to act in an untrustworthy manner. This is often referred to as having a 'BENT' for dishonesty, which is a four-letter word that is used to describe this trait. People who have a propensity to become dishonest may be more likely to engage in activities such as lying, cheating, or stealing. This behavior can have serious consequences, both for the individual and for those around them.
