I think of Ne and Se as forces that create, while Ni and Si are forces that conserve.so the mindset of each is:
Se sees reality ( his life ) as 1 big summer
Si sees reality (his life) as 1 big autumn
Ni sees reality (his life) as 1 big winter
Ne sees reality (his life) as 1 big spring
it fits all the descriptions you guys posted
So if you think that this universe is comprised of deterministic forces which would correspond to Ni and Si and then there are chaotic forces that allow something new to come into existence, this would be Se and Ne. That's the metaphor that I use.
I'd take out adjective "insecure" and replace it with "brave and bold". Types that have Ne as dominant function aren't insecure about using it. They enjoy having unpredictable future, living and thinking a step ahead. To outside observer it may seem like they are always trying to escape the present moment.Ne - The Insecure Novelist - This type bases itself with the presented environment but it seeks for more than that, it looks for the deep meanings and assigns the bigger pictures to them. It looks at things as parts to a bigger system, screws for a master plan and to find the actual plan it uses imaginative tools.
I call the Ne-dominant type the Seeker or Searcher, because on the outside it looks like they are always looking for something jumping from one weird thing they encountered to the next, as well as the Meaning Giver because it seems like Ne gives meaning to the objects it encounters in the outside environment. It picks up an object from environment then creates some random context around it. Ni works differently. It actually subtracts meaning from environment and kind of just sucks it inside into the mind of the Ni-dominant person so then Ni-dom walks around with his or her head full of meaning

Se is just enjoying sensory input of the moment. I was driving today deep in my own thoughts then I saw a nice looking car on the road of yellow hue and immediately got drawn into the present moment just savoring the look. It's the ultimate "ooo shiny!" syndrome.Se - The Hype(r) Sensors - Looking at the environment presented before it's eyes, the function seeks for incentives that attract attention, it searches the bright lights and the physical world. Often it wouldn't go beyond the shallow facts (perhaps if it's developed enough along with Ni). The function users will usually act upon the immediate data instead of asking too much questions of why. (I've added this part for you - with the how and why theories, also the Ne above would probably fit into your "why" part)
In evolutionary sense I think Se is tied to expanding your territory, to wanting more in the physical world, while Si is tied to maintaining and fortifying your territory, maintaining what you already have in the physical world. Then as I mentioned T/F is simply a scale of how competitive the individual is - strong T = very competitive, strong F = very cooperative.
I disagree with statement that sensors act with no delay. Se-sensors may act with no delay because they are trying to always live a step ahead. But Si-sensors will hesitate and act slowly. I like this article that illustrates how different thinking styles would compete if they have to play a game together: http://greenlightwiki.com/lenore-exegesis/Game-Board_Exegesis. For Se: "Make moves that make a big impact, that surprise, can be seen, are dramatic, stand out from the rest of the current action. Do things that grab the attention of the people around you. You might not see how that leads to victory, but the whole path cannot be seen right now. Surely action that gets you noticed is the only way, though!" So Se is like winning the game using the strategy of surprise factor in the physical world, for example, like hitting someone when they did not expect it. It is a strategy of out-doing other people, doing a lot, doing more than others, taking on action while your opponent hesitates, sits around and thinks. Si to the contrary emphasized being conservative in your moves. I don't think sensors think any less, that ISTJ spends less time referencing his or her Si than INTJ spends referencing his Ni. It is just that their mind values different things so to intuitives their 'moves' look sort of poorly thought out.(It's pretty obvious why I called both functions as I did - sensors act with no delay upon what they sense and the novelist will devise great stories of imagination to fit each object it finds in its place in the bigger story)
ExxPs which are either Se-doms or Ne-doms are the personalities that are most commonly diagnosed with attention deficit disorder as they find it difficult to concentrate on the present moment. To the contrary IxxJs are the types that can sit and read a textbook in library for 6+ hours. They learn slowly, but typically have superior ability to concentrate. The downside is that the breadth of their knowledge is usually very narrow as they prefer to learn a few subjects in great depth. While ExxPs go for breadth of learning rather than depth so upon initial meeting they make for interesting conversationalists.
All introverted functions are highly specific to the individual, not just Ni, so all of Xi functions can be described as "individual thinking" or subjective thinking. By validation I think you mean interacting with the outside, or behaving objectively, or in accordance to some outside standards. Only extraverted functions do that, but it is not because they seek validation. They simply do not exist otherwise, by their definition they have to be objective.Ni - The Paranoid Puppeteer - This function will probably present itself as more of an individual thinking rather then asking for validation, it treats things that Ne perceive as an "underlying meaning" as shallow and seeks for even deeper and more thorough understanding. It will often switch perspectives and will try to define and examine every possibility unlike the Ne function that will come to the situation heads on with one POV.
Ni will also stick to what has worked in past. Ni is conceptually conservative while Si is conservative in the physical world.Si - The Memory Banker - Unlike Ni, this function will run to the other extreme. Storing data as it's most basic thing with a lot of detail intake, basing itself on memory and recollection along with past experiences. The users of such a function would stick to what works and what seemed to work, and always incorporating new information. Although it doesn't mean this function won't search for patterns on-the-way to base it's decision and will most likely be correlated with Ne.
>.< ... this forum is clearly lacking on TeI think the problems in your understanding bases itself in the fact that you want to incorporate it into your how vs why theory, but remember - "If the facts don't fit the theory, change the facts" Albert Einstein.
