Dr Wiener continued: \"In a large number of modern secular democracies, there\'s been a trend that folk are identifying themselves as non-affiliated with religion; in the Netherlands the number was 40%, and the highest we saw was in the Czech Republic, where the number was 60%.\"+ b0 T) O, x, e2 k6 [- ^

However, Dr Wiener told the conference that the team was working to update the model with a \"network structure\" more representative of the one at work in the world.
