The more we study, the more we understand
The more we understand, the more we learn
The more we learn, the more we know
The more we know, the more we forget

The more we learn, the more we forget.
The more we forget, the more we learn!

 The more we learn, the less we know.
The less we know, the more we learn!

This is something that our mind have achieved thru learning and gain of explicit knowledge, then comprehend and linking inside implicit knowledge. After massive of collection knowledge and over period of time “process”, it had immerged into tacit knowledge.

In other words, tacit knowledge maybe come from “born by nature” (the inheritance of genetic), family teaching, living environment, cultural influence, education background, experience (unique individual grow up path), etc. Explicit knowledge is mostly from learning and education teaching. Implicit knowledge is just way in between.*

* This is still needed more scientific research and proven over this relationship of knowledge, if someone very particular of my wording or sentences.

As always, the knowledge that we can share, show, present, test by exam, etc are mostly explicit knowledge. It is only tip of the iceberg that other person can be “seen”.
