I was in Christchurch, New Zealand a few months ago. Walking downtown, they had classical music playing. I thought it a little odd and so I asked one of the locals about it.
Turns out, they did some experiments and showed that by having classical music lightly playing throughout the downtown core, a decrease was seen in the number of petty crimes.
This to me is hilarious. If music can have this effect on the actions of people, what else can your selection of moment by moment stimuli have on your life? What will you consciously chose to put in your life that will unconsciously have an effect on your life?
