there are 2 kinds of functions' strenght: weak and strong
other are nuances of strenght, not so useful. socionics has no "dimensions" and texts with that have other doubtful parts

beside general weak N traits, weak Ne is when is hard to understand what is more or lesser important in a situation/object, to suppose correctly its traits which are not on a surface (alike motivations of people).
an example is redundant suspicion to people, assigning to them wrong traits. this often correlates with emotions - negative emotions predispose to negative opinions and expectations, positive emotions - to positive idealizations

nonvalued - is when you don't want and get no pleasure from that, but more perceived as "needed". in bad mood that can be not done good as ignored to try good. an example of what can be too generalized traits based on surface similarity. for example - some black dog barked and then all black dogs will get negative expectations, while a color should not correlate with the behavior
