This is the difference between knowledge vs skill
Knowledge is being told something and being able to regurgitate it. Skill is being able to aromatically implement it without concentrating. It's a result of experience or practice and your neural pathways adjust and refine themselves with each iterative attempt you make until your neutral networks eventually find an efficient algorithm to implement your intent.
This is why you can't just TELL an inexperienced driver, bike rider, guitar player, juggler, programmer, artist, computer user, etc. How to do a skill. They have to TRY and try REPEATEDLY until the neural networks in their brains have been exposed to multiple attempts and have had the opportunity to adjust and refine their algorithms.
I don't know if you remember learning to ride a bike, but when I did, I practiced and practiced and didn't seem to be making any progress until INSTANTANEOUSLY it just HAPPENED! I was astonished that suddenly the bike was staying upright. I didn't FEEL like I knew any better or that I was doing anything differently. Just suddenly the bike stopped falling down. I had a similar experience when target shooting as a 14 year old kid. The NRA instructor told us at the beginning that we'll practice and on about the third day, it'll just click and we'll be able to hit the target. On exactly the third day, that's exactly what happened with me.
So, if you have a skill and you're trying to teach someone else, don't get mad at them if they don't get it right away it even if it takes them longer. Every brain functions a little differently and no one has conscience control over those very very low level, neural functions of pattern recognition. It will happen when it happens. Additionally, if the brain has ALREADY formed a neural pattern match for a similar skill, it could take them LONGER to pick up the new skill out concept because their neural networks will have to UNLEARN the old way in order to learn the new one.
And considering "bias"... Think POLITICS!
