So if you imagine a computer as an analogy...
Bits/bytes come in, and they get sorted out by the processor.
In cognitive typology, the four J functions are four different modalities of sorting out that information. And just like computers, our brains make countless micro-judgments per minute using those functions to organize our sense of the world.
Judgment is a whittling down process. Perception brings to our mind an unfiltered panorama of ....well, perceptions... and judgment is what differentiates the elements in the data.
So for example, every second your retina is hit by something like 90+ frames of perception. Each frame carries loads of information, but none of it is very useful on its own. It needs to aggregate a few thousand times in order for it to become useful to daily human life.
So actually, judgment takes information and first applies a very coarse consolidation process, like so:
At the bottom we see a basic registration of Perception, such as "hot", "cold", "bright", "circular", "square"
. As we move up toward the top of the pyramid those dots merge into more complex conclusions that account for more variables, including previously reached conclusions.
Judgment identifies the basic elements in the imagery before us. It goes from identifying simple shapes and hues, to conclude a thing like "that's a lamp", "that's my car" or "there are my keys!". It takes discrimination to distinguish what is a lamp, and where a lamp starts and ends.
The same operation is eventually involved in distinguishing abstract concepts from one another, grammar, and even philosophy. Human intelligence is, in many ways, just simple mammalian intelligence with a lot more processing power. Which means we just have more layers of processing to reach more abstract thinking.
In the diagram above there are 5 levels of consolidation. These are just arbitrary; it's a gradient in reality, but what it shows is that smaller conclusions form the backbone of more complex conclusions.
How it works
So at each "level" of processing in this pyramid, the psyche reduces
environmental variables down to fewer, by drawing conclusions, then only consciously manages those conclusions.
So if you saw a beautiful scenery with a lot of rich detail, judgment comes in and says "tree" "bird" "ball" "road" street" "little boy" and the nuance is omitted.
This is what allows judgment to take what is essentially an unquantifiable, endless stream of information
(P) from the environment, and make sense out of it, for pragmatic or even subjective purposes.
Here is a video that does a great job of explaining these differences between judgment and perception:
Sorry ivan! I didn't have time to answer the Ti question! But I figured this post is long enough as it is.
