Totally false. In fact, the most recent cognitive research suggests that the brain stores information based on "connections"... the more connections between certain bits of information, the more easily you can recall some or all of them. Emotional connections can also serve an important role as well.
So, the more you know (and the more you understand how it all fits together), the easier it is to retrieve it...
Not exactly. You didn’t read it right. I said “somewhat.”
In fact the more data your brain holds the longer it takes to retrieve it.
That is what I said.
