12/ So what does CFT tell us?
CFT tells us that in ill-structured domains, concepts are hugely variable so reasoning from concepts are insanely hard.
In fact, extracting generalisable principles from case studies is close to impossible!

13/ It turns out that experts in ill-structured domains DON'T reason from first principles as much. They tend to reason from past cases instead!
(Sure, they may TALK about concepts and principles, but the concepts are clusters of cases in their heads.)

14/ As a programmer, I find this difficult to accept. Isn't reasoning by analogy lousier than reasoning from first principles?
But it DOES resolve a question I've always had.
Which is this: why is it that Charlie Munger reasons so much from analogy?

15/ This brings us to Ideas 3 and 4 of CFT, which happen to be the two central claims of the theory.
Recall: the question that CFT attempts to answer is "how are experts able to perform under conditions of novelty?"
We know now that ill-structured domains have a lot of novelty.

16/ CFT tells us that experts do two things:
1. They construct temporary schemas by combining FRAGMENTS of prior cases.
2. They have something called an 'adaptive worldview', which means they do NOT think there is one root cause or framework or model for any event.

17/ So this explains why Munger, like expert doctors, reason a lot by analogy to prior cases.
After all, if businesses are always the result of context-dependent events and factors, then you CAN'T reduce case history into simple principles.
It's just too complex.

19/ What does this have to do with note-taking?
Well, now that we have the four big ideas, we can invert CFT's claims to get the pedagogical recommendations:
1. Expand the cases you know, so you have a larger set of fragments to draw from.
2. Inculcate the adaptive worldview.

20/ And how do the researchers recommend doing this?
The researchers note that you cannot reduce cases, and real world cases tend to be rich with many concepts. So ... the researchers recommend using a hypermedia system to store cases.
That is: a backlinked note taking system!

What are some good apps that help you with back linking? I’ve attempted this with a series of tags as I find articles and archive them in Evernote, but I feel it is harder to search and jump in/out/through these concept ribbons
