The Two Types of Knowledge: The Max Planck/Chauffeur Test (2015)
I also found that knowing something pretty much equals to being able to explain it to someone. I thought I knew many things until I tried to explain them.
Or, in other words, there is a sort of &quot;internal&quot; knowledge that seems to heuristically cut corners and generates or fosters the illusion of knowing. True knowledge does not cut corners. Which is what some of the posters have expressed as well.
