Of the ‘hand-me-downs’ of cultural heritage, religion and politics stand out as familial keepers along with language and biases. Shaking the beliefs of our parents is not a probable thing. If you were born a Catholic and a Democrat and hate Jews, chances are you will remain Catholic and Democrat and hate Jews. Likewise one born in Iran will grow up Moslem and be taught to hate Jews and westerners.
Yes, these individual traits can be altered but not easily. Altering can be accomplished by one of two ways: institutional brainwashing or self-education (accompanied by deductive thinking). Because they are changeable, that is proof that those mental states are not required for the intellectual functioning of an individual. Indeed, they are obstacles to intellectual functioning rather than ‘proper’ ideological guidance.
One can only imagine the obstacles of changing cultural identity, the first – and most important -- is the individual must come to grips with altering -- voluntarily -- one’s own psyche. It might help if the realization is made that the existence of these mental albatrosses are really not necessary at all!

Deductive and categorical thinking can dissect the subject’s mind’s excess baggage (self-analysis of neuroses comes to mind). This can be facilitated through ‘free association’ like the engineer’s tool of ‘free-body diagram.’ (I am not a psychologist though I think I might have been one in a previous life.)
