The researchers examined whether intelligence measured in early adulthood predicted subsequent marriage and continued marriage.
They found positive associations.
Men with higher intelligence scores were more likely to marry during the observation period.
Among those already married, higher intelligence was also associated with a greater likelihood of remaining married rather than divorcing.
The researchers considered different dimensions of intelligence, including verbal, numerical, and logical abilities.
Verbal intelligence showed a slightly stronger association with entering marriage than the other measured abilities.
The correlations were modest, however, and should not be interpreted as evidence that intelligence determines whether someone marries.
The study also considered socioeconomic factors such as income and social status.
Its findings suggested that intelligence retained an association with marriage outcomes beyond some of those measured characteristics.
Nevertheless, observational research cannot establish that increasing someone's intelligence would directly cause them to marry or remain married.

These findings provide an important counterbalance to sensational claims about extremely intelligent men being romantically disadvantaged.
The available evidence does not support a simple conclusion that higher intelligence makes men less successful in relationships.
Instead, different studies examine different questions.
One investigates how desirable hypothetical intelligence levels appear to potential partners.
Another examines how measured intelligence relates to actual marriage outcomes.
Those are not interchangeable measures.
A person might receive a slightly lower hypothetical attractiveness rating at the 99th percentile while still possessing characteristics associated with positive real-world relationship outcomes.
The apparent contradiction becomes less surprising once the differences between the studies are understood.
Why Dating Preferences and Marriage Outcomes Can Tell Different Stories
Romantic attraction is not a single event.
It develops through multiple stages.
Someone may initially notice another person's appearance or confidence.
After a conversation, they may become interested in the person's humor or intelligence.
Over time, they may discover shared values, emotional compatibility, and reliability.
A long-term relationship introduces additional considerations.
Partners must navigate stress, responsibilities, family obligations, financial decisions, and changing circumstances.
Qualities that influence initial attraction may not have the same importance during every stage.
For example, a person might find someone intellectually impressive but feel little immediate romantic chemistry.
Another individual might not initially appear extraordinary but become increasingly attractive through kindness, consistency, and emotional support.
The same principle applies to marriage.
Marriage is influenced by many factors beyond attraction, including cultural expectations, personal goals, economic circumstances, opportunities to meet partners, and attitudes toward commitment.
Intelligence may relate to some of these factors.
Higher cognitive ability may influence education, employment, communication, or planning.
Those associations could contribute to marriage patterns without proving that intelligence itself makes someone more romantically attractive in every situation.
Conversely, hypothetical preference ratings may reflect expectations that change once people interact with actual partners.
Someone who initially imagines an exceptionally intelligent partner as intimidating may discover that a particular highly intelligent individual is warm, funny, and easy to talk to.
Real relationships provide information that hypothetical descriptions cannot.
This helps explain why psychological findings must be interpreted according to what researchers actually measured.
Does Exceptional Intelligence Make Socializing More Difficult?
Popular culture often portrays highly intelligent individuals as socially isolated.
Fictional geniuses are frequently depicted as brilliant problem-solvers who struggle with ordinary conversations.
They may appear emotionally detached, impatient, or unable to understand social conventions.
These portrayals can be entertaining, but they are not reliable descriptions of everyone with high intelligence.
Cognitive ability and social behavior are distinct characteristics.
A person may perform exceptionally well on intelligence tests while also demonstrating strong interpersonal skills.
Another person may possess average measured intelligence while experiencing significant social anxiety.
Social confidence depends on numerous influences, including personality, learning experiences, environment, and opportunities for interaction.
It cannot be inferred from IQ alone.
There may be circumstances in which individuals with unusual interests or abilities find it difficult to locate people who share their passions.
But this possibility should not be exaggerated into a general rule about highly intelligent people.
Someone interested in advanced mathematics might enjoy connecting with others who share that interest.
They may also maintain meaningful friendships with people who have completely different hobbies.
Human connection does not require identical cognitive abilities.
It requires some combination of mutual interest, respect, responsiveness, and willingness to engage.
The belief that extraordinary intelligence inevitably produces loneliness risks becoming a self-fulfilling stereotype.
If people assume that highly intelligent individuals are socially difficult, they may approach them with unnecessary hesitation.
Likewise, highly intelligent individuals who internalize that stereotype may underestimate their own ability to connect.
A more useful perspective recognizes that social relationships involve skills and circumstances that can change throughout life.
Why Communication Can Matter More Than Intellectual Performance
Communication is one of the central activities of romantic relationships.
Partners communicate when expressing affection, planning their schedules, resolving disagreements, and discussing their hopes.
They also communicate through small everyday behaviors.
Remembering an important event, asking about someone's day, or responding thoughtfully to a concern can convey attention and care.
These interactions do not require extraordinary intellectual ability.
They require engagement.
A person who communicates clearly may make their partner feel understood even when discussing complicated subjects.
A person who communicates poorly may create confusion despite having excellent analytical skills.
For example, someone might recognize that a disagreement involves several logical misunderstandings.
They could explain those misunderstandings in detail.
But if they ignore their partner's emotional concerns, the explanation may fail to resolve the conflict.
The issue is not whether their reasoning is correct.
It is whether the conversation addresses the needs of both participants.
Effective communication often requires flexibility.
Sometimes a partner needs practical advice.
Sometimes they need encouragement.
Sometimes they want an explanation.
Sometimes they simply want companionship.
Recognizing these differences can help relationships function more smoothly.
Intelligence may assist with understanding complicated situations, but the willingness to listen remains essential.
The Hidden Importance of Feeling Equal in a Relationship
Equality in romantic relationships does not require partners to possess identical abilities.
One person may earn more money.
Another may have stronger organizational skills.
One may be more intellectually analytical, while the other excels at navigating social situations.
These differences do not necessarily create problems.
Difficulties may arise when differences become associated with unequal respect or decision-making power.
A partner who consistently dismisses another person's opinions because of perceived intellectual superiority may undermine the relationship.
