Many years ago I helped in a study of mouse intelligence.
Mice were placed in a maze and had to find their way through to the food. It soon became obvious that different mice showed different patterns learning the maze.
Type A mice would just wander around, often trying the same passageway forever, never finding the reward.
Type B mice would try each passageway, never trying a dead end twice until they found their way to the food.
Type C mice just sat and seemed to be thinking. Then they would set out and without an error go straight to the goal.
This study proved conclusively why so many of the great inventions and advancements throughout history have been made by A Non-A-Mouse.
