Zoom. Pew pew pew! Lightning fast. I'm ALWAYS wrong; there's no other way for me to be.
I am pretty similar. Though I'm right frequently enough that it discourages me from changing my snap judgment ways.
Virtually instantaneous assessments of what I am encountering as: useful, practical, making-sense, not-making sense, beneficial, congruent, in-congruent, etc.
If I see a flower, I'll instantaneously decide what shade/tone/etc. best describes the colour, whether it is well-formed, how long it might last before wilting, if I like the perfume, who that I know might like it, whether I would want it, whether it is likely to be fertile (seed-producing), what kind of insect/bird might be attracted to it, if it has any place in my past memories - and what associations it might have, etc. The notion of just looking at it and experiencing the flower, without making judgements, or connections to other things is extremely outside my subjective experience.
Yes, I make aesthetic judgments pretty fast. Like or don't like, moves me, leaves me cold etc. I usually have to take some time later to reflect on what led me to my judgments though. I rarely reverse my judgement on an aesthetic matter.
[MENTION=13730]PintoBean[/MENTION] - what made you ask?
The judgments that I make which are wrong, are usually due to me not having all the required data, and calling things prematurely.
How about practical matters?
When I come across an investment opportunity, I can't rest/sleep until I get my head around all the factors (intrinsic, extrinsic, personal, etc.) and firmly decide whether it is a good prospect.
