What sort of thinker are you? Visual or Verbal?

I'm not a psychologist. And I'm pretty glad about that. But I have in my short life noticed something very odd about a lot of intelligent people - they don't seem to understand certain concepts that appear very straightforward to me, while they may find certain other concepts easy that to me are pretty hard. It has been known for a long time that "intelligence" is a multidimensional thing. There is no one measure that can tell you how "intelligent" you are, and the "IQ" is a notoriously unreliable number to attach to it. What is it really measuring? Who knows?
That said, there does appear to be at least two axes that seem somewhat meaningful in assessing people's aptitude for certain fields of endeavour, and these are what I call the "visual thinking" axis and the "verbal thinking" axis. I don't know whether they are mutually exclusive; maybe some people think excellently along both axes, and others are daft no matter which way you tilt the graph.
Visual thinkers conceive of topics by, well, visualising them. In their mind's eye they construct the concept and explore it as if they were handling it and peering into its nooks and crannies. They like diagrams; they get a lot out of practical demonstrations of procedures. They think of things as systems, rather than as discrete objects.
Verbal thinkers are quite different. To the verbal thinker, the instructions are key. Protocols & standard operating procedures. I sometimes think visual thinkers are more prone to accepting an authority-based view of things. Concepts are related in a rigid ontology, which can be useful for some fields of endeavour, but verbal thinkers are not great at thinking outside the box.
And for these reasons, I think scientists tend to be more visual than verbal in their thought processes. They need to see something; understand how it breaks down and rebuilds. Verbal thinkers perhaps make better lawyers or administrators. I don't know.
I was thinking of all this as I watched an episode of Marcus du Sautoy's excellent BBC show "The Beauty of Diagrams". It seems to underline the point - scientists and mathematicians seem to see the world in a different way to our verbal thinking friends. To the visual thinker, a rose by any other name smells as sweet, but to the verbal thinker, if you change the name of something, you change its nature. The human brain is a very strange thing.
Is there a moral to this story? I don't think so, but speaking personally I have noticed that I get on much better with visual thinkers. If I was a verbal thinker I would probably say the opposite, and be just as emphatic in my conclusion. And here I am writing words to get that point across. Irony is not the 51st State of the USA.
