As Americans have become more tribal, isolated, and downright lonely, the need for quality friendships is at an all-time high. Yet, some of the most important relationships begin when we aren’t looking for them. Sometimes something seemingly insignificant, like a simple hobby or a mutual love, slowly grows into a real connection.
Dr. Arthur Brooks shared his insights into friendships on the Mighty Pursuit podcast. He explains that there are three types of friendships, and the one that matters most is a useless friendship.
Aristotle believed friendship was the secret to happiness
(Discussion begins at 1 hour into the video.) Brooks traces the value and importance of friendship back to the famous philosopher Aristotle. He explains that Aristotle believed the ultimate secret behind a happy life was friends. Brooks says, “In the Nicomachean Ethics, he [Aristotle] said there’s three levels of friendship that bring more happiness. And if you get stuck at lower levels, it’s going to be a problem for your life.”
The first type of friendship is transactional. These are people with whom you do business or have a casual acquaintance. You don’t really know them on a personal level. The relationship is friendly, but if business or a reason for interacting stops, so does the friendship.
Brooks describes transactional friendships, saying, “There’s nothing wrong with it, it’s just incomplete.” He continues, “If that’s all you have you’re going to be hopelessly lonely.”
The second type is friendships of beauty. They are chosen out of admiration. These are people we want to be around. Brooks describes it as, “You’re magnetic. It could be because of your physical beauty, your sense of humor, your intelligence, or your success.”
Relationships built on admiration are better than transactional, but Brooks warns, “If that beauty goes away, so does that friendship.”

Useless friends are the best
Aristotle described the friendship that brings the most satisfaction as Atelic, meaning it has no specific end or goal. Brooks calls it “Useless. It’s cosmically, beautifully useless. And so if you want to be happier, you need more useless people you just love.”
Describing the characteristics of this type of friend, Brooks shares, “you’re walking together, shoulder to shoulder, into the future and looking at something you both love mutually.” He continues, “There’s always a third love in these perfect friendships.”
Examples offered by Brooks might be a couple loving their children or best friends who love a sports franchise. Brooks says, “It can be dumb, or it can be cosmic. But the whole point is that third love is the glue that makes that, that useless relationship beautiful and perfect to you.”

Science loves a useless friendship
Research supports Aristotle’s belief that having a friendship without an agenda makes for a richer and happier life. A 2023 study in Frontiers found that friendships valued for the stimulating companionship and shared activities predicted higher well-being, life satisfaction, and personal growth. Best friends aren’t based on networking or usefulness.
A 2024 study in the National Library of Medicine found that high-quality best friendships lowered loneliness and boosted self-esteem. Meaningful relationships can begin with a shared love, but over time, become a part of who the friends actually are.

A 2022 study at Cornell University revealed that repeated physical proximity and similar interests strongly increased the likelihood of friendship formation regardless of background or social differences. Activities like walks, hobbies, sports, and creative interests offered a shared space where even unlikely friendships grow.
Brooks suggests the most important friends come from connecting over the smallest things. They don’t happen because we need them; more so, they exist for their own sake. These “useless friendships” are grounded in mutual joy and common loves. They may seem small or incidental at first, but the Atelic relationship shapes our happiness the most.
