There is logic to this invisible fence induction, based on how the brain writes to memory. When the brain writes new memories, it adds feeling tags to sensory content. Our memory has both sensory content and emotional tagging. This schema allows our memory to use both sides of the brain, with the sensory content more left brain and the emotional tagging more right brained. The left brain is more differential and the right brain is more integral. The left allows us see differential nuance and the right allows us to catalog with similar.
This schema is also useful to the animal brain, in that if a new situation was to trigger a previous memory, and the attached feeling is good or bad, the animal can react to the feeling without thinking. If I see a new food, that look like a food that made me sick, that sick feeling, from the previous memory will make you avoid it. You do not have to use trial and error, until you figure it out rationally. Emotional thinking works this way but this has some pitfalls.
Although our memories are designed to use both sides of the brain, consciously approaching memory, from the left side of the brain or the right side of the brain will give two different analysis for the same memory. The reason this is so is, although there is endless combinations of sensory content; five senses in endless combinations, there are only a smaller finite set of emotions used for all the tags. The emotional tags will get recycled will be apply to a wide range of different sensory content; right brain integration is the area under the emotional curve. For example, if I asked you to name your top ten favorite foods, these will all have a similar good feeling. However, these foods can be as different as soup and steak.
The rational thinker tries to not allow the emotions to lead. They try to stay left brain; Mr Spock. The right brain will often bring up block data; ten favorite foods. The Left brain is better for focusing on each item; differential is slope of the emotional curve at a given point. If the emotional tag is less, then the left brain can break down this block of 10 into 10 individual units, that can each stand alone and have their own history and source of tagging.
The problem with emotional thinking is, one starts with a right brain emotion, and will get a block data effect of unrelated sensory things other than a common emotional tag. For example, if you say the name Trump, this name also brings up other hateful and fearful, but unrelated memories, that are not Trump, such as Hitler. The rational person can analyze each item separate, while the emotional thinker often uses block data, that can amplify the feeling; emotional confusion overlap.
This can work both ways. Your ten favorite foods can each separately make you feel hungry; left brain. The right brain, via the entire block of ten favorite foods can cause that nice feeling to amplify; cook all of them for a party. The invisible fence is more right brain and makes use of unrelated block data to help electrify the zap collar.
Depression is an extreme form of emotional thinking. This can be chemical or caused by emotional fixation. If this case, that one feeling of depression stays turned on. That means the brain's memory tagging process, is giving your new day to day sensory content, as well as your recalled memory, this same negative stamp of depression. These freshly stamped memories become part of a growing block data, that then reinforce the depressed feelings; spiraling loop. Fake news does this on purpose; invisible fence.
I believe we need to treat information like we do our food supply; food for thought. We should still allow freedom of speech, but we can also label speech, like we do food, based on their nutritional or harmful ingredients. With this labelling, the consumer of information can decide and not be brain washed without their consent.
Sometimes, salad gets boring ands it is fun to eat junk food. ButI also want to know if horse meat is being sold as prime beef, so I don't buy the wrong thing and get ripped off. But as long as the butcher labels it horse meat, then let the buyer choose the butchers free speech. Violations will take away press credentials, and make such shady businesses vulnerable to liable suit. Wouldn't it be nice to have places to go that specialize in wholesome and nutritious food for thought and trust it is, but also still be able to find junk food with the triple cheese burger with bacon and liverwurst; properly labeled as not the best diet. While also avoiding shady butchers; fake new, selling tainted meat. Although, if they label it tainted, it may still be a good cheat alternative to feed the dog; properly labeled animal feed free speech.
