Ne as Vulnerable Function
The individual is highly skeptical about ideas and opportunities that appear not to lead anywhere specific, and seeks assurance that new innovations will definitely bring material benefits. He prefers the kind of ideas and innovations that offer solutions to existing problems rather than the kind that have uncertain consequences and are likely to bring upheaval and unnecessary change. The individual may tend to forcefully restrict other people's activities in areas he thinks they have no natural talent in. At the same time, he or she is prone to make errors when judging whether or not a person is capable of doing something. The individual generally does not try hard to understand multiple viewpoints, but concentrates on developing only his own. He is not very good at intriguing others with his ideas, even when they have significant merit. The individual dislikes it when people evaluate others' potential to engage in activities or develop skills in which they haven't had experience yet; above all he is uncomfortable with such discussions by other people regarding himself. He is inclined to be either over-skeptical of his own potential or going to the other extreme and overestimate his possibilities in specific areas on occasion.
