Impulse vs. Compulsion: What's the Difference?

Edited by Harlon Moss || By Janet White || Published on October 5, 2023
Impulse is a sudden urge to do something without premeditation. Compulsion is a strong, often irresistible urge to perform an act, usually driven by psychological factors.

Key Differences

Impulse and compulsion are both related to behavioral psychology, but they are not synonymous. Impulse is often a sudden, spontaneous urge to do something. These urges can be momentary and may not have a profound psychological basis. Compulsion, on the other hand, is a more enduring and often irresistible urge to perform a specific act, frequently rooted in a psychological condition or emotional state.
When one acts on impulse, the action is often short-lived and might be a reaction to immediate stimuli. For example, grabbing a candy bar at the checkout counter is an impulsive act. Compulsion, however, generally involves a level of obsession or anxiety that drives the action. For instance, compulsively washing hands due to fear of germs reflects deeper psychological triggers.
Grammatically, both impulse and compulsion function as nouns. While impulse is often used as a standalone term ("an impulse to run"), compulsion is frequently seen with qualifying words like "obsessive" or "irresistible" to specify its intensity or psychological roots. Impulse may pair with lighter adjectives like "sudden" or "brief."
In summary, while both impulse and compulsion describe urges that lead to actions, impulse is usually a fleeting urge without a deep-rooted psychological basis. Compulsion, in contrast, is often an overpowering need that has a psychological or emotional underpinning, compelling the individual to act.
