Unusual Mind occurrences crop up all the time. They frequently announce their arrival with the impression, "That's obvious. I can't believe I didn't think of that!"
Why does it take an unusual mind to analyze the obvious? If something is obvious why must it be analyzed? Doesn't obvious mean self-evident?
Candles and oil/gas lamps were in use when Edison thought up the light bulb. This doesn't mean Edison wasn't an inventor. But from the standpoint of unusual mind Edisons' bulb isn't all that unusual, it's a brighter source of light.
Drums and smoke signals preceded the telegraph and megaphones preceded the electric amplifier. The need to amplify sound surely became evident early on in civilization's life cycle and I'm sure someone within a group was known as the best shouter. I'm also betting that someone cupped a hand to the ear as a means to capture and direct sound into the ear canal, and then used both hands to improve amplification of their voice. The cupped hand amplifier suggested the design of the ear trumpet and when used in reverse the ear trumpet became the megaphone - a louder shouter.
The megaphone and the ear trumpet were certainly improvements but not all that unusual. It would be more realistic to say they were inevitable.
Maybe some of what we identify as unusual mind stuff, comes from paying attention to thoughts rather than things. Part of the unusual mind may seek to improve rather than discover.
Inversion is an important trait of unusual mind thinkers.
Consider the lowly, often loose towel rack. People grab the leading edge of the towel and pull down and out jamming the towel in the narrow space between the rack and the wall. Yanking on the towel pulls the rack away from the wall.
Inverting the usual question, "how can I make it easier to disengage the towel from the rack?" leads to the idea, "how can I make it easier to disengage the rack from the towel?"
Turns out the answer is obvious - gravity. It takes no energy to make things fall. Lifting the leading edge of the towel upward allows it to disengage from the rack and fall freely.
Try it and let me know if it works for you - inversion that is. I already have a secure towel rack.
