After looking at the press release again, I changed the title of the thread. According to the article it only takes 10% who are committed to a certain belief to change or become the majority opinion in their society.
Solus,
You are right in that we can have two diametrically opposing viewpoints at the same time. I have not read the study, it costs $25 to download, but I would think there would be a "war" literal or figuratively speaking for supremacy. We saw this in pre-NAZI Germany in the 1920s with the NAZIs and the communists fighting for control in that society. And keep in mind what Tom pointed out yesterday- only 3% of the colonists actually fought in the revolution.
