1) What goes on in your mind when you're thinking? How would you describe it?
Its hard to explain and, since I'm visual, I'll do it this way:
Its like a constantly turning kalaiedescope from which I can pluck pieces. I will, at some point, get a flash from, seemingly, nowhere and pause it to pick similar colors and/or shapes for examination... are they similar? and, if that interests me, I'll go deeper to see if they are exactly alike or if they fit together like puzzle
pieces. This is a constant process from the time I wake in the morning and stare at the ceiling for around 15 minutes just thinking to when I'm doing washing dishes or watching TV. With commercials, for instance, I notice the patterns and types of appeals they use and whether they're effective or more/less so than another and why.
Sometimes its annoying when I want to turn it off... the kalaidescope that is.

or when I get really obsessed with something. Couple that with an artist's eye and I reeeally want to turn it off sometimes. My eye can, innocently, fall on my china cabinet and I see every reflection on the glass door and every shadow on it and everything in it and their shadows/reflections.... my mind goes over the time of day, light source and the consequent effects, changes in color and what pigments they are and the perspective from my positioning, what brush would capture it... on and on and on. Did you know if you drove down a city street with all the lights of stores turned on, other car headlights and street lights and your mind consciously perceived them all, you would loose it?.... your mind that is.

Yeh, I think about that!
2) How much does logics weight in on your decisions and how much does feelings come
into play?
Logic rules! It is my very best friend that can always (well mostly based on my own limitations like missing some critical piece of data) be depended on. I examine, analyze, examine and analyze to be fairly sure I haven't. Feelings? I'm very tempted to say not at all but I suspect I might have them just because I'm human but
they have to be so weak and fleeting to grasp or hold on to. I'm pretty sure they're so immediately pushed down with thought that it appears I don't have them except for really extreme situations. I've read the "feeling" thread and think that's what I'm gathering but would not have otherwise known I even had them routinely. It might appear to some that I am tuned into them but I'm not.. one of two things are happening. Either I've learned to "act" them when needed or, when it looks like I've had a "gut" one, I've already seen the pattern because of that kalidescope thinking
and I don't need time to "re"think. I already "know" the "new" person, situation or
the subject from seeing previous patterns so it looks like its a snap or emotional decision (since no one thinks that fast lol) but its not.
How do you determine whether you've over-thinked?
When I become paralyzed and can't act on what I've thought about.... but don't try to convince me of that then. LOL
3) How easily can you go through the steps you've taken to arrive at a conclusion?
To myself? Except for simple things like purchases or why I did something routine
the way I did, I can't and I've tried. I wish I could. It would save me some problems with this or that one believing I'm psychic no matter how hard I try to convince them I'm not. I know I've been watching the kaleidescope, seen the pieces,
and they've "congealed" to a form... though I don't know when or how long I've been
looking. That's the closest I can get.
Is it automatic? Or does it involve some translation to get it into a form understandable by others?
No, its not on the easier stuff that I can explain. I know/devise the methodical, logical, steps I went through but once I have they're out-of-mind and they might not match another logical thinker's.. we all have our unique approaches. I'm pretty sure "N" might differ from others. When I try to
retrieve them to explain, it comes out all wrong or I've forgotten.... but I'm still sure its right and won't give an inch if its disagreed with... that or I better hear something I hadn't considered.. unlikely. Boy, does that ever sound egotistical...
but that's the way it is time tested and, now, accepted. Philosophy is a different matter. I can with that as I was trained in it and it has a specific, logical, language/approach.
4) Anything else you feel like sharing.
Well, yeh... this is so long, I might be "F"... nah, just kidding from the other thread... its not just "F" that does long ones. With me its because I'm not used to writing and/or conversing and not good at it. This also isn't an easy subject for
pete's sake.... not if you really want to share with someone wanting to know. And that's a dangerous question to ask an INTP who's analyzing LOL... let's just leave the door open on this one. K?
Oh, yeh... the reason I love rpg's and card games so much is because that is how I turn it off... crosswords too.
Edit: sorry for the typos... this is just too long to find them once on the edit page.
