Instinct is the atavistic response to a real or imagined emotional stimuli. Fight or flight. Two responses to a perceived threat.
Chess is a thinking game. Not a knee jerk response. And so we need to train the mind to reach the higher centers; to find the other responses. To look for out of the box answers, to find new options.
I think Ilham has asked the right question here. To learn more, do go and read "Emotional Intelligence" by Daniel Goleman. Here is a very brief and abbreviated version by me.
Instinct is a fear response and a very powerful stimuli. It has a direct loop to the brain stem (which is the old brain of even pre-caveman days.) When fear is triggered the impulses reach the old brain first and not the higher centers ie the neo cortex.
Now the neo cortex is where creativity, reasoning etc is found. But the impulses take a few seconds longer to reach these centers. If you are to continually trigger the fear response, you can drown out the thinking faculty.
Just using this very basic model, do you see why civilisation has tended towards order and rules. Towards education. This is necessary for progress. It is to enable the thinker in you to emerge.
Can you also now see why Lim Zhuo Ren needed to be attacked when he tried to explore for alternative answers; a solution to his current dilemna? Why Sumant and Mark needed to be attacked?
The continuous firing of fear impulses. The drowning out of thinking. Another way of looking at this is that fear prevents your access to knowledge and reasoning. Actually the seniors may have more knowledge than the juniors now. But they have too much fear and that reduces their fighting strength. So the great equaliser is to instill more fear into the Juniors.
An amazing recipe. Now all cannot fight in the real World.
Incidentally, this fear is also injected into the parents. And so we have this vicious cycle. It is not that we do not have World beaters. It is just that we have injected too much fear into the system and into the players.
Does that now explain why some of the Juniors are backsliding? They are constantly attacked. They have no tools to deal with these vicious attacks. And then you blame them when they want to run away. And you attack them further when they want to learn how to fortify their minds. And when you do manage to separate them from their support system, you say they cannot think.
Don't you think this is a little crazy? And to add insult to injury, they now ask where is our World beaters?
