How do you form flashcards out of mental models you encounter and want to remember and use? Could you post an example?
- PacifyFish 8y agoSure thing. I’ll typically make a few cards at first trying to test different aspects of the MM (general concept, example applications, given definition identify the MM, quiz any internal associations I have with it like if I learned it in a specific context, etc.) then I can delete ones that aren’t useful and/or add others later. Let’s use the mental model of inversion as an example. I found this one in a Farnam Street blog post about Charlie Munger. Here are some cards I might create: Front - what is the principle of inversion? Back - when you want to try to maximize something, instead try minimizing its converse. Or vice-versa. Front - what mental model might help if you’ve unsuccessfully tried implementing programs to increase innovation in your company? Back - inversion. Rather than thinking of ways to increase innovation, can you instead think of things that are decreasing innovation and eliminate those? Front - what’s another way to think about reducing time spent on work tasks? Back - invert the problem. Try to increase time saved on nonessentials (e.g. laundry service, meal prep, outsourcing) Front - what’s it called when you work backwards through a problem you’ve already tried to work through forwards? Back - inversion Front - what would Charlie Munger ask you if you came to him with a tough optimization problem? Back - “have you tried inverting it?” This is a bit contrived, but I hope this gives you a sense of how I think about creating cards for mental models.
