Final answer:
The term relating to the inability to control desires is compulsion, which in Freud's theory can result from unresolved psychosexual development. Compulsive behaviors, such as drug addiction, are one way this can manifest. Displacement is another related phenomenon.
Step-by-step explanation:
The term that describes a situation when individuals cannot keep their desires under control is generally related to the psychological concept of compulsion. In Sigmund Freud's psychoanalytic theory, such behavior can result from a failure to properly progress through the psychosexual stages of development. An individual may display compulsive behaviors, such as drug addiction or engaging in excessive activities, as a result of unresolved conflicts in these stages. Compulsion can also manifest through displacement, where individuals transfer their inappropriate urges to a more acceptable or less threatening target. Scarcity of means to satisfy given ends is ubiquitous in human nature, thus individuals must sometimes relinquish desires which they would prefer not to.
