If 3.5% of the population takes action, society can change. - Harvard University political scientist Erica Chenoweth investigated various revolutions and protests in the 20th century and found that protests involving more than 3.5% of the population always produced some kind of change. She has been researching this since the 2000s, and has found that nonviolent protests are twice as likely to succeed as armed conflicts. If you think that the world can change if four people out of 100 people participate in a movement, wouldn't you want to take action to solve a social issue that you are concerned about? On the other hand, some people say that this 3.5% rule cannot be applied directly to social movements in modern democracies, since it was calculated based on the results of a survey of 323 nonviolent movements that took place around the world between 1900 and 2006 with the aim of overthrowing the system, resisting invading forces, and secession. The world has been changed little by little by various people. It is not only those in power who have created today's society, but also the people. Even if you think your contribution may be small, why not put your will into action?
