Inspired by one of my heroes, Charlie Munger, I decided to attempt to document my “lattice work” of worldly wisdom — both learned and to be learned — here.  Hopefully this will give me a chance to internalize it and put it to good use.  What is worldly wisdom?  Let’s hear it straight from Charlie:

“What is elementary, worldly wisdom? Well, the first rule is that you can’t really know anything if you just remember isolated facts and try and bang ’em back. If the facts don’t hang together on a latticework of theory, you don’t have them in a usable form.  You’ve got to have models in your head. And you’ve got to array your experience—both vicarious and direct—on this latticework of models.”
A Lesson on Elementary, Worldly Wisdom As It Relates To Investment Management & Business, Charles Munger, 1994.

The way I’m approaching this is to write a blog post on each topic that I add here.  This will firstly give more context to a particular idea and secondly allow me to internalize it better by organizing it in writing.  I might change the organization as the list grows, but for now I’ll just use a bullet list.


Mental Models


Here are some tricks (in more modern vernacular “hacks”) that can be used to deal with the limitations inherent in our human nature or other difficult problems.
