We are what we think

The mind is a deeply complex organ. Not only does it generate thoughts, store memories, govern logic and control many bodily functions but it also guides mood, social behaviour and attachment style. It can be taught to change and adapt through its capacity for neuroplasticity. 

Thus working our way back from programming is possible but can be akin to leaving a cult. If I raise you from birth to be a racist you will have to work your way out of it through critical thinking by realizing over time that people are not less than by virtue of their race. Interventions might be the starting point which start your conversion process. 

Understanding what is true or false can take a long time because planted information requires it be examined carefully. If your frontal cerebral cortex is only fully formed by age 25 by then I could have filled your brain with all kinds of information some of questionable veracity. 

Small wonder that entire sections of bookstores and libraries are dedicated to self-help and mental wellness. We can spend years undoing childhood trauma which was left unexamined. 

We can teach someone the rules of mathematics which they then take as a profession while they are members of Scientology and believe in Xenu. This is how we end up with appear to be gaps in critical thinking. If your parents were in a cult you are far more likely to leave that part unquestioned.

I feel that this in part helps explain the mental disconnect that is Trumpism.
