In the Isaan - if you dont want to see, dont look

Is it the Buddhist's continual search for their inner "rightness" (The Noble Eightfold Path of Buddhism: Right Understanding, Right Thought, Right Speech, Right Action, Right Livelihood, Right Effort, Right Mindfulness and Right Concentration.) which hinders the Isaan's perception of the external?
The eightfold path is divided into three themes:

1. Good moral conduct (Understanding, Thought, Speech)

2. Meditation and mental development (Action, Livelihood, Effort)

3. Wisdom or insight (Mindfulness and Concentration).

On the surface any of these three themes would appear to indicate a degree of awareness of the external is required if the path of Buddhism is to be followed.

So where does the Isaan's ability to ignore things outside their immediate being arise?
People can be seen stepping over piles of rubbish, spitting on the floor next to the table they are sitting at, cooking their food in what can only be described as filth. The same disinterest is also shown in the lack of will of the Isaan to comment on something obviously wrong (e.g. stand and watch while someone throws a large garbage bag full of household refuse into the river but dont say anything).
Hopefully, it is not from a simple lack of interest in anything external and not of direct benefit to one self, although this is how it appears in Farang eyes?

The attitude "if you dont want to see, dont look" is omnipresent in the Isaan. When used as a means to avoid the menial (e.g. basic cleanliness in a restaurants kitchen) this attitude often projects an allusion of inherent laziness. Again, dont look/notice and it wont matter and, therefore, cannot give rise to any personal confrontation.

Footnote: No implication that the Isaan is a filthy place is intended, just that where filth occurs it is readily ignored.
