We all judge. We all live within a paradigm. And judgment serves a very important function. So, let's have a look.
Judging others serves one and only one function: For the Paradigm to hide from its host.
Before reading this article, we recommend to read the following articles for context: Paradigm, Paradigm Blindness, Flying Monkeys - Psychosis, When Fighting Abuse Actually Enables Abuse, Why are narcissists so effective at exploitation?, How can you really tell?, and On Stupidity [On Mass Psychosis of the Evil].
Judgment of other's behavior requires two things: 1) your perception that the behavior is a choice of the person and 2) that the behavior is approved or rejected by your paradigm.
Choice
In order to judge, you must believe that the behavior you are judging is a choice of the person. This operates from within Paradigm Blindness. On the lowest level, if you believe that being an alcoholic (or any addiction) is a choice and one can merely will it away, you will judge people doing so. "He should stop drinking.". "He should find a job and stop doing drugs." Good luck with that! That judgment really talks about YOU, not the person being judged.
Many people will tell you "I am a non-judgmental person", "I don't judge". When they say that, opposite is usually true. They operate from within Paradigm Blindness and they do not see the judgment they impart.
If a bear eats your garden you will not be judgemental of the bear. "He should know better.", "He should be punished.". You may want to kill the bear, but not to punish him, but to prevent him from eating your garden again. You can't judge if you don't believe that the person (or animal) actually chose to do the thing you are judging.
Now, this perception of choice is your paradigm's way of fooling you. You believe that you have a choice and consciously decide with free will to behave a certain way. That belief is then projected onto others, and here comes the judgement. The truth is that some behavior you choose and some you don't as they are dictated by your paradigm, and without your knowledge. And it is the latter that you will judge, not the former.
So if you can control your drinking and never confronted your paradigm with your oven addictions or compulsions (yes, you have them), you will think that addiction is a choice. And you will judge such. And this judgment serves only a function that you do not see your own addictions or compulsions that are not under your control, fooling you that either 1) you do not have anything like that and 2) you can control it.
Behavior being judged
What you judge is an important tell-tale about what your paradigm is. Here is the problem though: How do you explain to a fish what is water?
If you try, you will look like an idiot. Water? Where? Around me? I am in water? And it makes ME wet? Are you OK? Don't talk to Nemo, he is crazy.
Attempting to explain a paradigm and what it judges is the same. Because the paradigm rejects it. The judgment is all around you. You live within it. You fight for it. But you don't see it because you reject it. But you do see it, however in others.
If you are a messy person, consider it no big deal, or have your own logical justification for it, you will judge 'clean' people. Their cleanliness will be a slap in your face. So you will call them 'OCD' or 'uptight'. And perhaps they are but your judgment will really point to your 'water'.
That's why a 'confident' person may be called 'arrogant', 'cocky', 'confident', 'assertive', all depending on the judgment-maker. The judgment-maker's label will have NOTHING to do with the behavior being judged, and EVERYTHING to do with its own paradigm.
The judgment is used to hide your own paradigm. The bigger the judgment, or bigger one defensive or offensive becomes, the more important it is for the paradigm to hide as it feels threatened.
Judgment is a psychosis. It prevents you from seeing the world as it is, the people as they are. And this psychosis ,operating from Paradigm Blindness is susceptible to induced psychosis of Narcissistic Paradigm, which is what we call Flying Monkeys - Psychosis.
