I think that the real power of spaced repetition is not in flashcard applications like this. It is in behavior modification.

Let's take a real example to show how this works.

August 19, 2025. My wife called me in to help her decide what to do about a dentist that she thought was ripping her off. A couple of quick suggestions later, and she went to being mad at me about not having heard the problem through before trying to fix it badly. As soon as she was mad, I immediately connected with how stupid what I did was, and that this never goes well. But, of course, it was now too late.

Not a mistake I was going to make for a while. But, given my history, a mistake I was bound to make again.

I changed that. This time I stuck this into my spaced repetition system. Each time the prompt comes up, I remember that scene, holding in mind how it important it is to emotionally engage, not offer quick suggestions, and be sure to listen to the full problem in detail. It takes me less than 30 seconds. Reviewing this prompt, for my whole lifetime, will take less than 15 minutes of work. Just typing this up this time takes more work than I'll spend on it in the next several years.

This mistake hasn't happened since. Not once. And I believe it won't again in my life.

I have literally changed dozens of such behaviors. My wife says that it is like there is a whole new me. She can't believe the transformation.

All it took is looking at spaced repetition as general purpose structured reinforcement, and not as just a way to study flashcards.

I love this example because the correct, wise approach is so alien to my mind that I do not know how to respond to such situations. I am a professional problem solver, you described a problem, yet you do not want it solved? Just talk about it being annoying, like an immutable facet of the universe? Should I retort about my grievances with gravity making roof repairs a bear?

I wanted to chime in to say: this is me, I do/have done this, and am also seeking to change this behaviour. It has never once occurred to me to try using spaced repetition for something like this, so thank you to putting the suggestion into my brain! I intend to put this into action as soon as I'm able to.

Love this example. I started putting my Kindle highlights in the SRS—no prompt or anything, just the quoted text verbatim—and the effortless periodic review essentially burned the quotes in my memory for easy recall in moments when they were appropriate.

This is really inspiring. Doing whatever you gotta do to be a better support for your loved ones is commendable.

Can you give an example of what you record in your SR system? Is it the anecdote itself? Do you generalize the pattern? Is there a "front" and "back?" A cloze?

So cool. Would love to hear more - What app do you use? How often do you clear your inbox and how long does it take?

Interesting example with some questionable couple dynamics.

Sounds like you're not the only one at fault lol.

Do you get mad at your wife if she offers suggestions before emotionally connecting? And would it still be too late even if she realises how "stupid she was"?
