What the **** are you on?
Extended levels stress, especially during formative years, permanently kicks up levels of adrenaline. In the brain, the same chemical structure is nor-epinephrine. The focus becomes narrow, black and white, fixed on an absolute frame of reference, and addicted to being angry.
The amygdala and sympathetic nervous system are in permanent overdrive. When this happens, the brain focuses on less information and makes more tenuous connections. The brain relies less on the cerebral cortex and frontal lobe, which takes too long, and more on the "mamillary brain" to control the "lizard brain".
These get their names because they are common with lower mammals, like dogs, and reptiles. It is apparent when you look at your dog, it has no forehead. There is no cerebral cortex
The mammillary brain consists of the thalamus, the hippocampus and the hypothalamus. The thalamus is a "smaller processor". The hippocampus is predominate in memory. The hypothalamus releases hormones and triggers hormones in the body. This preps the body. At the same time, neural signals propagate down the brain stem, triggering the sympathetic nervous system and amygdala. The sympathetic nervous system regulates the body, the circulatory system and other stuff. The amygdala is a "muscle memory" brain that learns how to coordinate movement. Athletes, like baseball players, have great muscle memory.
This effect stands out in bold relief with PSTD sufferers. Coming back from the war, veterans that were in the heat of combat, will have flashbacks at the sound of a car backfiring. Rape victims also present symptoms. The use of drugs, like meth, are also similar. Early childhood abuse does as well. Early childhood is the worst because the brain develops into the condition. It is permanent.
Obviously, in the finer details it gets more complicated as the brain is a feedback system. Arousal in structures that depend on nor-epinephrine trigger other structures that use serotonin..
You can gauge what is going on by listening (or reading) for certain clues. We rely on external feedback to learn and 'be in touch with reality'. The lizard brain, mamillary brain, and the cerebral cortex, each use more and more external information to reach a conclusion. Each is therefore slower.
You can tell when someone is "not in touch" because they make statements indicating that they dismiss feedback. "I don't bother with graphs", "Data doesn't mean anything" , "Education is a waste of time", "All economists and statisticians don't know what they are talking about", etc. Sweeping generalization allow feedback to be eliminated. Facts don't matter because they already know what the "truth" is. They know because they can feel it. Their intuition tells them so.
You notice, of course, that things become "black and white". "Bankers friends who make commissions off the sales." Either you are Mother Teresa, living in abject poverty to feed the poor or you are completely selfishly motivated. There is no room for more than two possibilities. The concept of "and" eludes them.
The "black and white" description is literal. The thalamus processes primarily in black and white. Color processing is done in the occipital cortex. Obviously, thought processes that develop out of color processing are able to put things into a spectrum, a scale, rather than simplistic black and white categories.
They become fixated on an absolute frame of reference. The dollar is devaluing because the price of gold is going up. It doesn't matter that everything else is stable, even property value. This just means that everything else is devaluing, right along with the dollar. That is a separate issues.
And little things are magnified. A 2% rate of inflation is "out of control", a "massive devaluation of the dollar".
And, as you notice, they are perpetually angry. In fact, they are addicted to it. It is what they live for. Without it, they would simply fall asleep or be distracted by the next squirrel that ran across the yard.
So, it is right on target to ask "What are you on?" or say, "

". Crazy is, after all, a disconnect from reality, the rejection of feedback. And there drug is adrenaline.
I am, of course, just generalizing. I'm sure this doesn't fit anyone that comments on-line. There are, of course, bankers that make money for their friends. No one has found that proverbial one handed economist. The CPI is a fixed frame of reference. Suggesting that someone is either an adrenaline junkey or isn't is a bit black and white.
