Psychology suggests adults who rewatch familiar comfort shows may be drawn to familiar stories that place fewer demands on an overloaded mind

Scrolling through streaming platforms has never been easier. So it may be a bit odd that many adults, when they get to the end of the workday or evening, often retreat back to a specific television show, reruns of an old sitcom, that familiar period drama, or anything they’ve already seen before.

It's more of a cultural phenomenon now than just a personal niche preference.According to a PubMed-indexed article, psychologists suggest this may reflect how the brain manages information load, stress, and limited mental resources. Known as a comfort show, the brain gravitates toward predictable content because right now, we have an insane number of variables we are juggling.According to a ScienceDirect article, media psychologists have long argued that people do not consume entertainment only for novelty.

We also consume it as a means of emotional regulation to avoid depleting our psychological resources and to help balance our emotions during times when our brains feel overwhelmed.Why the brain loves repetition when it’s tiredPsychologists know that your brain is naturally inclined toward tasks that require the least amount of effort for you, especially during mentally strenuous moments.For us, this translates to the most likely scenario: That new Netflix show demands a whole lot of mental energy to absorb new characters, story plots, settings, and nuances.

With no need to understand the context, catch up on new twists, or care about a completely unknown character that could end up dead or doing something unexpected on screen, comfortable old shows cost your brain practically nothing to process.A widely cited framework, available through PubMed, in self-control research once proposed a “limited resources” model of self-regulation (Baumeister et al., 1998), suggesting that acts of self-control may temporarily reduce available mental effort.

However, this “ego depletion” model has since been debated, and findings are mixed.This concept, called ego depletion, has stuck, although it remains debated. Essentially, as a mental task becomes more complicated or requires repeated self-control efforts, the individual is not going to be as successful in the next task.The decision fatigue effectAnother commonly discussed concept is decision fatigue, which suggests that repeated decision-making may influence the quality or effort of later choices.

Some research supports this, though findings vary depending on context and methodology.According to an APA overview of decision fatigue, a long string of decision-making could weaken a person’s self-regulation, encouraging them to default to less complex options.As with ego depletion, some research suggests that effort in decision-making may be associated with reduced performance on subsequent tasks.The comfort show is a tool of emotional regulationOutside of cognitive tasks and mental exertion, familiarity can bring comfort and safety to our emotions.

Because familiar shows are predictable, they are less likely to demand attention or introduce unexpected emotional tension, which can make them feel more calming.According to psychology, the novelty in a new TV show means unfamiliar patterns, rhythms, emotions, and themes. All of these require new thought processes on your part, which are energetically expensive for your mind.Research in media psychology suggests that people often use entertainment not only for enjoyment but also for emotional regulation.

Your brain saves a few seconds by bypassing a few steps.

The neurological explanation for comfort shows bingesIf our brains are trying to save as many precious seconds and effort as possible, it only makes sense that familiar stories help us make this easier.Rewatch: It takes less effort; there is nothing to absorb; you’re not learning. Simply rest. Research in this area actually suggests a similar concept from developmental psychology:Interestingly, a related principle appears in developmental psychology. According to a study indexed in PubMed, Diana Baumrind's research on parenting styles suggests that emotional warmth combined with clear structure is associated with better self-regulation and social outcomes in children, particularly within the “authoritative” parenting style.According to her research, the children of parents who provide lots of warmth but also firm structure often get better outcomes in development, including having better control of their impulses and higher quality social interactions.What psychology has to say on comfort show habitsTaking it all into account, there is no one-size-fits-all explanation, of course, as to why many of us reach for the same shows. In essence, watching familiar shows may serve as a form of mental recovery for some people after cognitive and emotional effort.By providing a familiar and predictable world to relax in after a long day of hard mental and emotional exertion, watching rerun comfort shows doesn’t mean that you are avoiding reality, but rather giving your brain much-needed rest. In essence, the simple act of clicking play is the mental recovery many of us really need.
