I, however, was not speaking of people with traumatic or other brain injury. I was speaking about all of us in the normal everyday world. Deviance or other abnormalities are not at issue there. So speaking abstractly, it is wise not to attempt to compare the phenomena we see in perspective and rationale among liberals and conservatives with those who are abnormally impaired in some way.
I don't claim any expertise in the medical implications except in the area of addictions. But I do have a small measure of expertise in evaluating temperament and perspective in the normal world. I am an ENT/FJ by the way.
I think your statistics are flawed due to your sample size, cross section, and your not considering your own bias as a significant variable in your research. The test for temperament is the MMPI because temperament consists of aspects of personality. Abstract thinking CAN be learned, it is learned, and it is be learned by some relatively low intelligence people.
Not gonna get into one of these things with you Sunshine. You have previously made your opinion of my inadequecies, stupidity, ignorance, various 'ists and 'isms, prejudices, and lack of education abundantly clear. I suppose we can now add my bias to your list of personal criticisms too. Let's just leave it that I am a miserable excuse for a human being and you are perfect in all respects and let it go at that, okay?
Meanwhile, to the rest of you, thanks for the links to live feeds. Some are better than the one I had I think.
