Hi delta of percived Value make meme propogate faster

In a theoretical model on decisions in social networks (also called innovation adaptation), it was found that as the gap between the individual ́s perception of the options is high, the adoption speed increases if the dispersion of early adopters grows[1].

Pareto law of speed of propogation

Meme propagate through 50% of a network in in short time, and reach 80% in longer time (in students connected through a mutual social network it takes 10 minutes to reach 50% and about 100 minutes to reach 80%)[2].

Common opinion hub make meme propogate faster

It was also found that when there are hubs of common opinion the spread of adopting new ideas become faster[3].
