Two tendencies pull them in opposite directions. Seeing so much, visual thinkers get lost in aesthetic detail-a tendency I suspect is exaggerated by most artistic training. On the other hand, visual thinkers think in wholes. They love visual orderliness, balance, and proportion. Verbal thinkers constantly analyze, compare, relate, and evaluate.
Good writing is fundamentally biased-biased toward a particular point.
In writing, the elements of thought are not equal. Most thoughts are subordinate to other thoughts and all are subordinate to a single overriding theme. Good expository prose grows from a subtle analysis which ranks details so they can be ordered in support of a central theme and expressed verbally. To repeat, expository writing is based on a thought process that is, at heart, analytical. But everything can seem sublimely equal to a visual thinker.
