There are several purposes of psy ops (psychological operations) at different levels of distillation(depending on the target).
1 psychological operation, psyop
military actions designed to influence the perceptions and attitudes of individuals, groups, and foreign governments
The definition extends way beyond the military.
The main one is to social engineer the flock and drive them in a specific way. Then there are off shoots.
The deepest level that runs like a theme through out all psy ops is to have people co-create reality in a way that benefits the controllers of this reality (invisible fences) while maintaining an illusion that they have freedom of choice. In other words limiting potential and crafting that potential to create a particular overall circuit that benefits you know who.
Some of the psy ops work top hook a certain sensibility (like course in miracles) then lead people astray in a type of classical 80/20 disinfo. They lay out the cheese with poison in it.
At the bottom of most of these (including religions) is to fracture power of creation and divert it.
Look up some of the work of intel groups such as Tavistock. This is but one such group designing psyops.
Psyops are very sophisticated and utilize feedback mechanisms such as the internet. People think it was some kind of gift that the powers that be gave us the internet. It was so they could get feedback for social engineering purposes. The internet is an information gathering portal as well as a way to seed minds with codes that hive minds.
