Sure. But one might be biologically be lead to modes of thinking that would favor one ideology over another.
Everything we say or do is conditioned behavior, and has nothing to do with idealogy or genes. Genes, another unproven theory from a long list of other unproven theories
Wait, you are saying that DNA is an unproven theory or are you saying that genetic involvement in behavior is an unproven theory.
I picked 50%, for the time being.
At least half of your political philosophy is learned, however, your brain function can lend a hand in influencing whether or not you actually belief said philosophy.
I wouldnt say particular ideologies are inborn, but people often make their choice of ideologies based on the structure of what they learned as a child.
I personally am a Socialist, I use all of my mental faculties to examine everything I can find about politics and different ideologies against the backdrop of my own experiences and moral compass and I cant find it in my heart to identify as anything else; I'm a Socialist because I cant be anything else.
The only logical conclusion: we don't know. I'm looking for that option.
For instance, DNA may induce sympathy, or outrage at certain issues which could persuade our idelogical beliefs.
Also important to note is epigenetics which we are not born with, but controls protein expression and could also have impact on our ideologies. So like I said, impossible to know.
People who are saying it's 100% either are just plain wrong. Genes affect a person in so many different ways it's impossible for them to not affect ideology in some way. Same with the alternative.
I would personally say that ideology is mostly developed over time, with a hint of genetic influence - maybe 80/20.
