Haven’t read the book, but the article linked (and a lot of political neuroscience in general) makes it appear the author believes there are only 2 ideologies; liberal and conservative which is itself a wild idealogy… Can anyone who has read it or other work by her confirm/deny that?
A good tool/exercise for analyzing your (and other’s) beliefs is logic trees, with the goal of taking any complex belief and determined what your core axioms are, being on the lookout for tautologies (God is real -> because the Bible says so -> because God is real…) and axioms that don’t hold up to scrutiny.
If you do the exercise correctly then you should find that most of those “beliefs that can’t be objectively proven or disproven” have belief dependencies that can be objectively (and often easily) proven/disproven.
