Opinions and Bias are simply "Pre-Concieved Notions"
"We are forming opinions,like they are going out of style"-me
example: someone says to you " I was climbing trees this weekend, then asks you " What did you do?"
1. you most likely imagined this person climbing, in what your opinion of a Tree is.
2. yet unless you first ask them something like " what is a tree ",you don't really know what they climbed,or even if you know what climbing is to them,so your assuming your idea of climbing and a tree are at least similar.
If they say Oak tree,and in your mind you invisioned a apple tree,to a degree your bias toward the Apple tree,simply because that was your "first thought"
Now in a weeks time,someone else mentions some thing about Oak trees,while talking to you,you can almost bet,the idea of that person climbing the tree,will pop in your mind A Pre-Concieved Notion was just formed in your mind.
A long time ago,after reading/studying Betty Edwards book "Drawing from the Right Side of the Brain".I was hit by the Idea of Pre-Concieved Notions,after seeing how she taught students to draw by turning things upside down,thus seeing a object as "New" and not pre-conceived , and how dramatically the students drawing improved!
This is one think that is needed to " Live in the Now", this is why I try so hard to show how " Plato's Cave" and why,it is so important to learn and be aware of " being stuck in the Cave, due to our pre-conceived Notions. And the Heraclitus's "Everything changes and nothing remains still ... and ... you cannot step twice into the same stream".
To be stuck in old belief's and opinions,is Non-Growth
