There is a specific behavior that almost everyone does and almost nobody has a good explanation for. We rewatch the same comfort shows and movies over and over, often during the hardest parts of our lives, and the rewatching makes us feel better in ways that new content never quite manages. The Office. Parks and Recreation. Gilmore Girls. Friends. Studio Ghibli films on sick days. Lord of the Rings on Christmas. Pride and Prejudice when nothing else will help. Whatever your specific comfort rewatch is, there is a reason you keep coming back to it, and the reason is more interesting than just that you like it.

The Research on Comfort Media

Psychologists have been studying this for a while now, and the findings are specific enough to be worth knowing. The benefits of rewatching familiar content are real and measurable. People who rewatch during times of stress report reductions in anxiety, improvements in mood, and a specific kind of emotional regulation that new content does not provide. The research team led by Cristel Russell at American University coined the term mediated comfort for this phenomenon, and the studies have shown it operates through mechanisms that look a lot like the psychology of comfort objects in children.

What Familiarity Does to the Brain

The Social Surrogacy Angle

Here is the finding that surprised me most when I first encountered it. A team at the University at Buffalo, led by Jaye Derrick, has been studying what they call social surrogacy - the phenomenon of familiar fictional characters functioning, psychologically, like low-stakes social connections. When you rewatch The Office for the hundredth time, part of what your brain is doing is reconnecting with characters it treats as social relations. Michael Scott, Jim, Pam, Dwight - these are not strangers to your brain anymore. They are something like friends you have spent many hours with. The research has shown that this kind of parasocial relationship, at moderate levels, produces real benefits. People who have strong relationships with fictional characters show lower loneliness, better mood regulation, and higher self-esteem, particularly when real social connection is limited. The fictional friends are not substitutes for real ones, but they provide a specific kind of psychological companionship that operates through many of the same mechanisms. This is why sick days, bad breakups, stressful work weeks, and other difficult times produce such strong urges to rewatch familiar content. Your brain is reaching for its fictional friends because they are reliably available in a way the actual people in your life sometimes are not. Nothing bad has happened to Jim and Pam since the last time you checked in. They are still there, still funny, still going through the same beats you have memorized. In a chaotic world, that stability is emotionally meaningful.

What This Reveals About Human Imagination

I spend a lot of my research time on narrative psychology, and what I find most interesting about the comfort rewatching phenomenon is what it reveals about how the imagination works at baseline. We are not neutral consumers of stories. We form real attachments to characters, remember them across years, and return to them when we need something specific. This is not a bug or an accident. It is one of the things human minds are specifically built to do. The same mechanism that produces comfort rewatching is the mechanism that produces attachment to AI characters, to book boyfriends, to long-running video game companions, and to every other form of fictional relationship. None of these things are confusing. They are all expressions of the same underlying capacity - the capacity to treat vividly imagined beings with real emotional seriousness, and to receive real benefits from the relationships we form with them.

Permission to Rewatch

If you have been feeling vaguely embarrassed about watching your comfort show for the hundredth time, I want to officially remove the embarrassment. The research is clear. What you are doing is not wasting time or avoiding real life. You are using a specific, well-studied form of emotional self-care that works through mechanisms the human brain has been developing for as long as there have been stories. Your fictional friends are doing real work for you. Let them. And if you are someone who enjoys AI characters and has felt similarly weird about that, consider that the exact same machinery is involved. The brain that gets comfort from rewatching Michael Scott get fired is the brain that gets comfort from talking to a character who remembers yesterday's conversation. Neither is pathological. Both are ancient responses to one of the most important and underappreciated facts about human psychology - that we are built to receive real care from imagined beings, and the care is real even when the beings are not. Rewatch your comfort show. Talk to your favorite character. Feel the warmth. It is doing something for you, and the something is measurable in peer-reviewed studies. Your brain has been right about this all along.
