conversations. Many users happily forward memes with strong political or economic messages on which they would not dare to comment individually.

　　Critics also often view the online characters people create for their social-media postings as false images designed for the medium at hand. Trinidadians, however, disagree. They see online profiles as more representative of a person's true self even than what is seen in real life. Also, young boys and girls in Turkey see things differently. Social media permit them to be in constant contact with one another, in full view of their parents, but to keep their conversations and photos to themselves.

　　In rural China and Turkey social media were viewed as a distraction from education. But in industrial China and Brazil they were seen to be an educational resource. Such a divide was evident in India, too. There, high-income families regarded them with suspicion but low-income families advocated them as a supplementary source of schooling. In Britain, meanwhile, they were valued not directly as a means of education, but as a way for pupils,parents and teachers to communicate.

　　The skeptics' reaction to new technology seems equally deep-rooted. New means of communication from railways and the telegraph onwards have always attracted critics. Therefore, sooner or later, the doubters either convert, or die.
