The narrowness of certainty appeals to the left hemisphere
The right hemisphere can understand unclear and fleeting images, while the left requires clarity and stillness. Also, The right hemisphere has broad, global, and flexible attention, while the left has narrow attention. Certainty is also related to narrowness, as though the more certain we become of something the less we see. To put this in the context of the neurophysiology of vision: the fovea of the human eye, a tiny region in the retina at the center of gaze, is the most pronounced of that of all primates. Here resolution is about 100 times that at the periphery. But it is only about 1° across. The part of the visual field that is actually brought into resolution is no more than about 3° across. This is where the narrow focused beam of left hemisphere attention is concentrated: what is clearly seen.
