Scientists discover tipping point for the spread of ideas (it's 10%)

> Scientists at Rensselaer Polytechnic Institute have found that when just 10 percent of the population holds an unshakable belief, their belief will always be adopted by the majority of the society. Um, surely this statement needs to be qualified in some way? For example, I'd guess that over 10% of the population is "unshakably" pro-life, and over 10% of the population is unshakably pro-choice, and yet it is impossible that both beliefs will become held by the majority of society.

As I was reading the article, it became clearer and clearer that it had increasingly serious issues. I got to thinking to myself, "Please, whoever wrote this paper, please don't be physicists stepping outside their domain and making the rest of us in physics look like fools." Then I saw. Physica Review E. =(

Then every political opinion that more than 10% of the population strongly believe in should have the majority at some point, all of them. It seems that this is a simple and obvious counter-example.
