Replaying conversations: why you keep going over what you said

It's the review that starts once you're alone: on the walk home, in the shower, at 2am. You go back over what you said, find the worst moment and play it again, usually with corrections. Psychologists call it post-event processing. The researchers who first described it called it a post-mortem².

People who do it describe the same things¹:

Almost everyone, after a job interview or an argument. It becomes a problem when ordinary chats set it off and it lasts for hours.

It's a core part of social anxiety. In the best-known account of how social anxiety works, the post-mortem is one of the things that carries the fear from one occasion to the next². You don't need a diagnosis for any of this. If the list above sounds like you, the rest of this page applies.

The replay is a rehearsal. Your mind treats the awkward moment as a mistake to learn from, and runs it again to find the version where you get it right. People say so themselves: they revise old conversations in the hope of not messing up the next one¹. That is why it feels useful, and why it can go on for years. There is always a next one.

The trouble is the footage. During the conversation your attention was on yourself: your voice, your face, how you were coming across. So the memory you replay is mostly how it felt from the inside, with very little of how anyone else reacted. Every replay goes back to that same record and comes out a little worse. People who go over a conversation more afterwards rate how they did more harshly, and the rating keeps dropping with time².

Then comes the verdict: they think I'm odd, they won't ask me again. CBT calls this fortune-telling: treating a guess about what someone thinks, or will do, as something you saw. The guess is reliably too harsh. In one experiment, students sent into a room in an embarrassing T-shirt expected about half the people there to notice it, and about a quarter did⁵. In another, people who had just talked to a stranger guessed the stranger liked them less than the stranger actually did, and they kept making that mistake for months with people they saw every day⁴.

Most people's first move is to shut the thought out: picture a door slamming, drag it to the bin, sing over it, pick up the phone¹. It works for a minute. Then the thought is back, because trying not to think of something keeps part of your mind checking for it. In the classic experiment, people told not to think of a white bear went on to think of it more than people who had been free to think of it all along³.

The other move is to check. You text "sorry if I was weird last night", or ask a friend whether it was fine. They say it was, and you feel better for an hour. Exposure therapy calls this a safety behavior. The calm gets credited to the checking, so next time you have to check again, and you never find out the evening was fine without it.

Both moves treat the replay as an emergency. Buddhism has a calmer picture. An early teaching says pain arrives as two arrows: the first is the thing that happened, and the second is what you add to it. The flat joke was a first arrow, and a small one. The three days of going over it are the second, and that one you can learn to put down.

The advice that people who live with this rate highest isn't a technique. It's to give up the idea that you can control what people think of you¹. Alfred Adler built a practice on exactly that, and it is the center of these steps.

The third step is the one that changes things. Once their opinion stops being your job, the replay has much less to work on.

You will still say the wrong thing sometimes. Adler's followers had a name for accepting that: the courage to be imperfect. Sometimes getting it wrong is the price of being in the room at all. And being hard on yourself won't buy a better result. Nobody has ever hated themselves into someone they like¹.

Going over the odd conversation is ordinary. If it's taking hours most days, costing you sleep, or you've started avoiding people so there is nothing to replay, talk to a doctor or a therapist. CBT for social anxiety works on exactly this loop.
