If I live to be 100, I will never, ever understand the conservative mindset

55. Is this even real? How did you come upon this "theory"

I went to your link; there's even a disclaimer at the bottom of the book graphic regarding the lack of educational credentials of the author whose name when googled did not reveal a hit or summary within several pages unlike the UAI index and the general all purpose information on the Wiki...Perhaps this comment is better served under "Creative Speculation..."? with a link back to the OP. Unless your answers here would point to better citations, I'd have to declare this "book" about the theory major misinformation. I also mean no offense because that "theory" I did find fascinating, at the very least. I've known many "lefties," "southpaws," and stories about early correction of handedness.
