Why Your Brain Replays Embarrassing Moments
Why does your brain replay embarrassing memories from years ago? Learn how memory, rumination, and growth shape those cringe worthy moments.
You’re brushing your teeth, driving to work, or lying in bed trying to fall asleep when your brain suddenly decides it has something important to discuss. Remember that thing you said at a party in 2016? Yes, unfortunately. The joke nobody laughed at? I remember. Want to experience it again in remarkable detail? Not particularly. Too late. Within seconds, you have been transported back to an interaction you haven’t consciously thought about in years, complete with the facial expressions, the awkward silence, and the overwhelming desire to somehow travel backward through time and stop yourself from speaking.
Most of us have memories like this. Maybe it’s the time you confidently said something that turned out to be completely wrong. Maybe it’s a text message you wish you could retrieve from the cellular network and destroy. Maybe you waved enthusiastically at someone who absolutely was not waving at you. Years later, the event itself is completely irrelevant to your life. There is a very good chance nobody else remembers it, and even if they do, they probably aren’t dedicating much of their Tuesday afternoon to thinking about it. Yet your brain occasionally pulls it from storage as though it has uncovered important new evidence in an ongoing investigation.
So why does it do that?
Your Memory Is More Connected Than You Think
It is tempting to imagine memory as a giant filing cabinet. Something happens, your brain creates a file, and that file gets stored away until you intentionally go looking for it. Actual memory is much messier. Our experiences become connected to emotions, people, places, smells, thoughts, and other experiences, which means something happening today can activate an old memory without you consciously searching for it. Researchers studying recurrent negative autobiographical memories have found that these kinds of memories are common, including among people who aren’t seeking treatment for a mental health condition. They have also found connections between recurrent negative memories, rumination, and psychological distress.
That doesn’t mean an embarrassing memory popping into your head is evidence that something is wrong. It means your brain is doing something brains are quite good at doing: connecting what is happening now with things it learned in the past. The trouble is that the system doesn’t always distinguish particularly well between information that remains useful and the memory of calling your seventh grade teacher “Mom.”
Embarrassment is especially good at getting our attention because, although it feels deeply personal, it is usually a social emotion. Think about the memories that make you cringe the hardest. Many involve being judged, rejected, misunderstood, exposed, or simply realizing that other people may have seen you differently than you wanted to be seen. Humans are profoundly social creatures, so paying attention to those experiences makes sense. If you tell an inappropriate joke at dinner and everyone suddenly becomes extremely interested in their mashed potatoes, remembering that uncomfortable feeling might help you make a different choice next time. That’s useful learning. Remembering the same dinner years later while shampooing your hair is considerably less useful, but your brain doesn’t necessarily check the expiration date before retrieving the lesson.
When Remembering Turns Into Rumination
An embarrassing memory appearing is one thing. What happens next can be another. You remember something awkward and think, Why did I say that? That turns into What did everyone think of me? which becomes Why was I like that? Before long, you are conducting a full performance review of your younger self at midnight.
Psychologists often use the word rumination to describe repetitive thinking about negative experiences, emotions, or problems that doesn’t necessarily move us toward a solution. Research has shown that rumination can influence the kinds of autobiographical memories we retrieve. In experimental research, people experiencing low mood who were prompted to ruminate subsequently recalled more negatively biased memories than people who were distracted from that mood. One uncomfortable memory can therefore become an invitation to search for supporting evidence. Your brain starts with remember that awkward conversation? and twenty minutes later you’ve assembled The Complete Collection of Every Social Mistake I Have Ever Made, Volumes I through VII.
At that point, we understandably want the whole thing to stop. Unfortunately, our most intuitive strategy isn’t always particularly effective. Decades of research on thought suppression have identified what researchers call a rebound effect. Trying very hard not to think about something can sometimes make that thought more likely to return later, although the strength of the effect varies depending on the person and circumstances.
The classic example is wonderfully simple: try not to think about a white bear. Whatever you do, don’t picture one. Definitely don’t imagine a white bear sitting in your living room right now. The problem becomes obvious pretty quickly. In order to determine whether you’re successfully not thinking about something, part of your attention has to keep checking for the very thing you’re trying to avoid. Embarrassing memories can work similarly. Frantically trying to eject one from your mind may give it far more attention than it deserved in the first place.
Maybe There Is Nothing Left to Solve
There is another way to respond when one of these memories shows up. Instead of arguing with it, suppressing it, or beginning another investigation into exactly what everyone at that party thought of you, you can acknowledge something considerably less dramatic: Yep. That happened.
Maybe you behaved awkwardly. Maybe you made a mistake. Maybe knowing what you know now, you would handle the situation completely differently. That last part is worth noticing because it may actually be evidence of growth. We have a strange habit of judging previous versions of ourselves using information, skills, maturity, and perspective that we only developed afterward. Of course you would do some things differently now. You aren’t the person who originally did them anymore.
There is an important distinction here between reflection and rumination. Reflection can help us understand an experience, learn something from it, and incorporate that lesson into the way we live now. Rumination tends to circle the same questions without producing much new information. Research into autobiographical memory has similarly explored the difference between more adaptive forms of self reflection and repeatedly analyzing negative experiences in ways that keep distress going. A useful question when an old memory resurfaces might simply be, Is there anything left for me to learn from this? If there is, learn it. If there isn’t, you don’t have to solve the memory again.
That doesn’t mean giving every previous version of yourself a free pass. Sometimes we really did get things wrong. Growing includes being able to recognize that, make repairs when appropriate, and behave differently going forward. But accountability and endless self punishment aren’t the same thing. You were there then, but you weren’t this version of yourself yet. You had different experiences, different skills, different relationships, different information, and hopefully a different haircut. If you wouldn’t expect someone you care about to remain permanently defined by one awkward moment from years ago, it may be worth questioning why you’ve created that standard for yourself.
Let the Past Go Back to the Past
Your brain is a learning system. It notices experiences, connects them to emotions, and uses what happened before to help you navigate what happens next. Most of the time, that’s incredibly useful. Occasionally, it means you’re lying peacefully in bed when your brain suddenly whispers, Hey. Remember karaoke night? And somehow you know exactly which karaoke night it means.
You don’t have to erase the memory. You don’t have to prove that it wasn’t embarrassing, and you don’t have to convince yourself that nobody noticed. You can recognize it for what it is: something that happened, something you survived, and perhaps something you’ve already learned everything you needed to learn from.
Then you can let the past go back to the past. Your brain will probably find something else to talk about soon enough.
