Mathematical model 'describes' how online conflicts are resolvedResearchers have produced a mathematical model to describe how conflicting opinions are resolved over articles that appear on Wikipedia, the collaboratively-edited encyclopaedia. The study maps the evolution of opinion over time, showing that even widely diverging opinions eventually converge. The researchers say this pattern in collective human behaviour is reminiscent of the interaction of particles in physics, such as when wind-blown grains of sand eventually create sand dunes.
