If marriage is being redesigned as a high-stakes quest for self-actualization, does that leave single people in a state of permanent misery? Popular culture often depicts the "single life" as a waiting room for "real life" to begin. However, modern sociology suggests that being single isn't just a lack of a partner—it is often a rich, alternative way of building a human connection.
## The "Greedy" Nature of Marriage
One of the most surprising findings in modern sociology is that marriage can actually shrink your social world. Researchers **Naomi Gerstel** and **Natalia Sarkisian** describe marriage as a **"greedy institution."** In their study, [*Marriage: The Good, the Bad, and the Greedy*](https://www.jstor.org/stable/20453580), they found that married couples tend to become more isolated, spending less time with friends, neighbors, and extended family than their single counterparts.
Single people, by contrast, often serve as the "social glue" of a community. They are more likely to support aging parents, visit siblings, and maintain diverse friendships. While a spouse might provide one deep connection, a single person often has a broad "convoy" of support that offers different types of emotional resilience.
## The Baseline of Joy
Does getting married actually make you happier? Psychologists use a concept called the **Hedonic Treadmill** to explain why the answer is more complex than a "yes" or "no." Most people have a "set point" for happiness.
A landmark 15-year study led by **Richard Lucas** at Michigan State University found that while people get a significant happiness "boost" around the time of their wedding, they eventually return to their baseline level of happiness.
> "On average, people were no more satisfied after marriage than they were prior to marriage."
In other words, marriage doesn't "fix" unhappy people; it mostly provides a temporary spike in mood before life returns to its normal emotional rhythm.
## The Rise of the "Single at Heart"
Social scientist **Bella DePaulo**, author of [*Singled Out*](https://en.wikipedia.org/wiki/Bella_DePaulo), coined the term **"singlism"** to describe the prejudice and stereotyping of people who are not in a romantic relationship. She argues that society suffers from a "marriage-centric" bias that overlooks the millions of people she calls the **Single at Heart**.
For these individuals, being single isn't a transition state or a "failure" to find a partner. Instead, it is a lifestyle that prioritizes:
- **Autonomy:** The freedom to curate one's own time and environment.
- **Solitude:** Using time alone for creativity and reflection rather than feeling lonely.
- **Diverse Intimacy:** Building a "family of choice" that includes friends, mentors, and peers.
## Success as a Solo Act
In his book [*Going Solo*](https://en.wikipedia.org/wiki/Going_Solo_(book)), sociologist **Eric Klinenberg** notes that the rise of people living alone is one of the biggest social changes of the last 60 years. He argues that solo living is actually a sign of **economic success and social freedom**. Historically, only the very wealthy could afford to live alone. Today, more people use their independence to engage more deeply with the public life of their cities, proving that being "alone" is not the same thing as being "lonely."
