Im dont have much economic knowledge but im a self-learn psychology student, correct me if im wrong

Many thing IS related to playing with psychology whenever there is an issue related to human being
Economy in the society is just like war, if u can grab the king pieces then u will be the winner
In order to do that, u have to face the opponents that stopping u
To defeat opponent in an effective way according to many strategy book including art of sunzhu, we have to know their next and future movement and plan, if u know what our opponent plans ahead, we can know how to set up a plan earlier and defeat their plan
To do that, we have to understand them, through the surface
There is no rule or law to do that but using psychology to analyze their behavior and find out what they actually thinking
This is the power of psychology

Also, psychology apply in many thing
For me is most as i dont think theres anything excluded
If we able to consider things in all perspective of the chessboard, we can be the king easily

Ya what u mention is mainly on business strategy, but isn't economy involve competition among each other too?
Sorry for my lack of understanding regarding economy
