Looking local means that you say "I am not eating now, because I am scheduled to eat later"
Generalized outlook looks at why I am not thinking about changing my plans, why I am not considering eating now and later, and so on.
It will be lack of openness, laziness, not willing to reconsider plans etc.
The local cause is easy to argue about and change.
The generalized cause is way more complex. Harder to understand, and much harder to argue about change.
You can convince a person to change his local plans. But saying that his rigidity is not good, is harder to show (maybe he is better off staying rigid and planned and so on. The value of a trait for a specific person is not easy to gauge).
When you look at life as a whole is indeed hard to decide what is good as a trait. Very hard to think about which constellation of customs etc. is best.
But this is actually a reason to favor local outlook. Because in the local one can easily decide, and manage his life for the better. Still, generalized understanding is relevant. One cannot ignore it. Only the small scale strategy has its value, which does not permit us to be stupid of the facet called global outlook. I only guess that the generalized aspect is generally less crucial than it seems and functionally it is good to focus on the local (without totally forgetting the general).
Generalized is less known. We may know more on local relationships than on global and complex ones.
Thinking about generalized stuff takes more energy. Emotionally, any generalized thinking is way more taxing. Thinking about oneself in a generalized way (self reflecting) is linked to a variety of negative side effects (see "the curse of the self" for a review about these effects)
PS. see Wegner and vallacher research on "Action Identification". Every activity can be looked at from a very generalized view (I want to be a millionaire) to the very local (I got to write this letter (in the check)). They say that too generalized a view is many times less functional than focusing on the lower level. It is after all the very small steps about which we go to concentrate many times in order to get things done.
