Most of the time, we go somewhere or we meet someone and we stay with the first impression about what we heard or what we know, people create stereotypes, a generalization of a person or a group of people that happens when we dont have the right or enough information, and we start making false judgments. This issue is that many times people talk without knowing.
For example we could see in Chimamanda Adichi's talk that people have one think about how is Africa. Chimamanda dint know that people like her could exist in literature, because she read all books with blonde and blue eye characters, they talk about their different climates, they ate apples, and other things she never knew because she had never been abroad, Nigeria was her home.
For her, start reading books from Africa showed her different worlds and opened her mind, she realized that books could also tell the stories of people like her. It saved her of having a single story of what books are. She wrote books about what she could see and what she recognized.
The danger of having a single story is that learning only about one part of the story may determine what you become later. It takes away your dignity, and makes some people have more power against others because they only tell them a single story about them and doesnt allow them to know the whole story or different point of view of things. People should have the complete information to have their own thinking, have many views aboout how people live or about diverse cultures.
" The one who writes the story has power. Stories can break the dignity of the people, but stories can also repair that broken dignity." Chimamanda Adichie
