A tipping point discovered on how many people are needed to change an opinion. They developed social networks with ‘individuals’ free to chat across the networks. Each individual held a view, but researchers added an alternate view, said consistently. If both had the same view, reinforced it, another view, moved on. If the individual then also had the new belief, the listener adopted it. After a while opinion started to shift. This study concluded the percentage of committed opinion holders necessary to ‘tip’ the majority into accepting the minority position was just 10%.
