Does new information change behaviour? I have observed that it does. Also- old information beheld in a new light can also change behaviour.

But, to your point, people that have heard your argument (aka "information") and have rejected it... generally don't need to keep hearing and rejecting your same argument. Unless, of course, the repitition is the catalyst to considering the old information in the new light.

"A watched closet never boils."

Ha ha. I think you need to attribute 005 on that one. It just goes to show that you can post on the boards 100 times a day, but if you miss the semi-semi-semi-annual L4D night... you are on the outside looking in.
