Creative people might be judged to be more insane because their thinking is often different than those around them. They think “outside the box”. They are curious, and entertain ideas most people don’t even think about. They question things other people just take for granted. They put things together differently. You can see this clearly in fashion. Most people dress in basic clothing they find in department stores or other clothes-selling outlets. Things that are accepted as currently fashionable. They may look nice and well put-together, but don’t really stand out from anybody else. People who are fashionably creative wear things that stand out from everyone else. They take risks. They pair things that don’t seem to go together. They may wear wild hats or jewelry or accessories. They may wear things that seem shocking or bizarre. You may think, wow, that’s really weird, yet somehow it works. Or you may think the person wearing that outfit is completely bonkers because no one but an insane person would go out in public dressed that way.
I think the more intelligent you are, and the more creative you are, the more you see things differently than other people. You don’t merely accept what you are told without questioning it. You look at the small details of things to study how they work. You watch ants scurrying around and think about how their lives compare to ours. You examine things closely. You don’t see things in black & white. You realize there are all different shades of meaning.
