Experiences, brain patterns and their roles in shaping our life

Some illogical thoughts seem to be the figment of a deranged brain, but they make total sense inside brains that have a corresponding pattern.
A Bedouin in the scorching heat, wearing thick black clothes, seems illogical to us, but it is very sensible to them, since they do protect them from the inclement weather.
Internal patterns can be different even within the same family. Members who grew up under the same roof and were exposed to the same principles and values could have different outlooks on life.
This divergence in internal patterns among siblings raised in the same environment, reveals the complexity of how individual minds construct their version of reality.
Two children in an inharmonious household, governed by strife, animosity and daily friction could develop opposite philosophies about marriage.
One could become averse to commitment, while the other could turn into a perfect companion.
Their shared experience goes through the filter of their temperaments and experiences. 

One sibling might have had a frequent exposure to the mother's anxiety, erratic behaviour and panic paroxysms, while the other might have had spend more time with his father and got deeply imprinted with his optimistic disposition.
This could lead one to view life as a challenge to overcome and the other to see it as a monster to fear.
These internal filtering systems become so deeply entrenched, that what appears an irrationality to one family member could represent a perfectly logical matter to another member.
Their brain's response to different situations is based on their unique interpretation of the experience.
This is what make irrational behaviors seem normal when viewed through the lens of the internal model whithin which they have evolved.
