Friendship and Loneliness: Exploring the Social Coin

As social beings, we all crave human connection and interaction. We thrive on forming relationships and building bonds with others. However, sometimes we find ourselves on the opposite end of the spectrum, feeling lonely and disconnected from those around us. Even surrounded by people who love us, loneliness can rear its ugly head.

Recent studies have highlighted the detrimental effects of loneliness on our physical and mental health, with some even calling it the modern killer disease. Julianne Holt-Lunstad, a professor of psychology and neuroscience at Brigham Young University, collated data from seventy studies and found that social isolation, living alone, and feeling lonely increased the chances of dying by about 30 percent. Not good.

On the other hand, spending time with friends can positively impact our health and well-being. It's not just about having a large number of friends but rather the sense of relaxedness that comes with spending quality time with them. According to Nick Christakis and James Fowler, authors of Connected, having happy friends who live nearby can increase our own happiness by 25-34 percent.

But it's not just about the number of friends we have; it's also about the quality of those friendships. A depressed friend is six times more likely to make us depressed than a happy friend is to make us happy. And while we may think of our online connections as friends, studies have shown that the number of Facebook friends we have doesn't necessarily correlate with the size of our social circles in the real world. I have thousands of friends on Facebook, so I know that’s true. I hardly heard from any of them during my recent hiatus from social media.

We need human connection and interaction to thrive

So, what makes a good friend? Professor Robin Dunbar, an evolutionary psychologist, has spent years studying the behavior of wild animals and exploring social evolution. He found that our networks are limited to around 150 slots, and we first slot in our family members before filling the remaining slots with unrelated friends. Dunbar also discovered that our number of friends correlates with the size of the key parts of our brains used in social situations. And yes, if you’re thinking “Dunbar’s Number,” you’re thinking of the right guy.

In today's world, where we are more connected than ever, it's easy to mistake online interactions for real friendships. But as Dunbar points out, it's important to have meaningful, offline connections with others before disaster strikes. These relationships are built on a sense of obligation and the exchange of favors, people whom we wouldn't feel embarrassed about asking for help.

In the end, we need to find a balance between socializing and solitude, between friendship and loneliness. It's okay to enjoy spending time alone, but it's important not to isolate ourselves completely. As social beings, we need human connection and interaction to thrive, to feel happy and fulfilled. So, reach out to an old friend, join a new group, and make meaningful connections that will enrich your life.

I recommend picking up a copy of Dunbar’s book, Friends: Understanding the Power of our Most Important Relationships. He wrote, “Friendship and loneliness are two sides of the same social coin, and we lurch through life from one to the other.” Most of this blog post is inspired by notes I took reading his book and our conversation on my podcast.
