For example, "The Scribbler", The Trainer says: "The person doodles or draws without a particular goal. Boredom - The person has no interest in the current topic or has tuned out completely. 'I would like to do something else now.'"
I'm a very visual person, and sometimes I scribble or doodle to help me think. It's actually because I'm more interested in something, and I want to explore (visually) some of the ideas around the topic. It helps me to relax and be more creative.
I could also see this being a poor interpretation in, for example, a design firm, or with a visual artist. It's true, they could be bored, but that isn't always the only interpretation.
Also, I see "The Patrolman" can also be a sign of insecurity, a way of minimizing space or being non-offensive. "The Eye Wiper" might just be because the persons contacts are bugging them, or maybe some medication is drying out their eyes. So there is a lot of room for interpretation that the article misses.
