The Coolidge Effect
People can experience renewed sexual interest when they encounter someone new and attractive, even when they are happy and sexually satisfied in their relationship. The Coolidge Effect is a term used to describe this phenomenon. It refers to the way sexual novelty can sometimes renew sexual interest and desire, offering one possible way of understanding the tension that can exist between long-term attachment and attraction to someone new.
The name comes from a well-known, and probably untrue, story involving President Calvin Coolidge and his wife during a visit to a chicken farm. According to the story, Mrs. Coolidge noticed how frequently the farm's rooster mated. She asked the farm worker to point this out to her husband. When Mr. Coolidge heard that the rooster mated with a number of different hens, he reportedly replied that Mrs. Coolidge should be told about that too.
Behind the humour of the story is an idea that has been explored in behavioural and evolutionary research: sexual novelty can sometimes stimulate renewed sexual interest. Similar patterns have been observed in a range of animal species. However, human sexuality is considerably more complex, and the Coolidge Effect should be regarded as one possible influence rather than a complete explanation of human sexual behaviour.
It is also important not to assume that this phenomenon is exclusively male. Women can experience attraction to novelty as well. In everyday life, this might be as simple as noticing that someone unfamiliar is attractive and experiencing a brief moment of sexual interest. This does not necessarily indicate dissatisfaction with a partner, a wish to be unfaithful, or a problem with someone's sexuality.
The distinction between attraction and behaviour is particularly important where there has previously been infidelity or problematic sexual behaviour. A person may experience attraction, sexual thoughts or an urge for novelty without acting on them. An attraction is not an action, and an urge is not a decision. Feeling attracted to someone new does not mean that a person has to act on that attraction.
This is important because the Coolidge Effect should not be used as an excuse for infidelity, compulsive pornography use, or other problematic sexual behaviour. A biological or psychological tendency may help us understand why something feels appealing, but it does not determine what someone chooses to do. Personal values, relationship agreements, consent and responsibility remain important.
There is also an interesting psychological element to attempts to suppress attraction. When something is presented as forbidden or completely off-limits, it can sometimes become more psychologically compelling. In this sense, believing that we should never notice or feel attracted to another person may actually make the experience feel more significant than it otherwise would.
Sexual novelty may be one factor in the appeal of pornography, but the Coolidge Effect does not explain or justify problematic pornography use. Where pornography or other sexual behaviour becomes secretive, compulsive, harmful or difficult to control, there may be many psychological, emotional and behavioural factors involved. Understanding the appeal of novelty is therefore only one part of understanding what may be happening.
The Coolidge Effect offers one possible way of understanding why sexual novelty can sometimes be appealing, even within a satisfying long-term relationship. Experiencing attraction or sexual novelty is not, in itself, evidence of a problem. The important question is how a person responds to those experiences. When sexual behaviour becomes compulsive, harmful or inconsistent with a person's values and commitments, understanding an urge may help explain what is happening, but it does not remove responsibility for the choices that follow.
