Under your nose

I bring you a story I found while roaming the net.

The manager of a housing co-op was increasingly frustrated with her tenants. No matter how much she reminded and badgered them, no matter how many meetings she convened, no matter how much goodwill there was for the task, the tenants would not, could not reduce their energy consumption.

Finally she hit an idea. What would happen if, she wondered, if the electricity meters were moved from the basement to a more conspicuous spot right beside the front door, so that each time the tenants left or entered their home they could see how fast their meter was spinning?
The metres were moved. Lo and behold, within a few weeks electricity consumption fell 30 percent.

Why did I post this you ask? I think its true that people would not care about something if they could not see it. This brings up another idea that if you did not see it than it simply does not exist, which we all know isn't an intelligent thought.
