Are there different regions of the brain that create a liberal, moderate, or conservative way of thinking? Are these particular and other types of political ideologies learned from our parents? The answer is probably both.
Like any other belief system we are most likely the product of genetics and environmental shaping. That shaping can take many years and it is okay to have a different political leaning at one age versus another. The critical thing is to understand your own belief system and values and act consistently with them. You may find that your values change over time based on experience and that is also okay.
Far too often people will get into strong verbal disputes about politics and it tends to be about one’s belief about how terrible this guy is or how great that lady is. In fact, most of us do not know our political leaders and it is also probably true that most leaders are decent people. What we really need to discuss in civil ways are our beliefs and why we think such beliefs can advance something good. It is okay to disagree. When it gets personal the conversation has moved from the beliefs.
As neural plasticity involves a type of shaping of the brain for thought, emotion, and behavior we can be fairly sure that our political philosophy has a place within the cortex that is dynamic and probably attached to emotional centers. When we connect the philosophy with reason and communication skill we have developed a real talent. When we remain at the emotional level and try to articulate our beliefs we might get a bit personal.
Stick to your own values and what you believe regardless of any leader. These are your beliefs and that is a good thing
