|Creativity Unleashed Limited - spot the cognitive dissonance|
Why? Because it is much easier to take a wonderful, attractive, but impractical idea and make it practical than it is to take a dull but practical idea and make it wonderful and attractive. So banish assumptions to begin with when trying to be creative, then re-impose them later as you refine your ideas and make them usable.
Sometimes assumptions can be downright dangerous, as I discovered in my teens. On my way to school I used to walk through the centre of Manchester, a busy city in the North of England. I went the same route every day and I knew which of the streets I crossed were one way streets. So like many apparently streetwise city dwellers I tended to show off my knowledge by only bothering to look down the street in the direction I knew cars would come from. Until the day a car went the wrong way down a one-way street and only just managed to stop with its bumper nestling against my legs.
So if you are with me in a city and feel the urge to snigger when I always look to make sure traffic isn't coming from the wrong direction in a one way street, suppress that urge. I am just making sure that I don't make a deadly assumption.
