Biological Basis For Creativity Linked To Mental Illness
The study in the September issue of the Journal of Personality and Social Psychology says the brains of creative people appear to be more open to incoming stimuli from the surrounding environment. Other people's brains might shut out this same information through a process called "latent inhibition" - defined as an animal's unconscious capacity to ignore stimuli that experience has shown are irrelevant to its needs. Through psychological testing, the researchers showed that creative individuals are much more likely to have low levels of latent inhibition.
"This means that creative individuals remain in contact with the extra information constantly streaming in from the environment," says co-author and U of T psychology professor Jordan Peterson. "The normal person classifies an object, and then forgets about it, even though that object is much more complex and interesting than he or she thinks. The creative person, by contrast, is always open to new possibilities."
Replace "Creative people" with Liberal or progressive thinkers and replace "Normal Person" with "Average American" and you can see why the great unwashed are so good at concealing from themselves the vile nature of their government. Bush is a "good guy, one of us" yadda yadda; that's it.
Then he goes off and rapes, murders steals and lays waste but "they" don't have to think about all this new infornmation because they "already know" the answer.
Libruls however are open to new information, they can "change their minds" without having major psychic surgery and, by definition they are therefore nuts.
