When young children are told stories and fairy tales, they embark on an adventure that drags them away from their everyday routine. Yet, on the other hand because there are lessons or skills to be learnt and remembered from a fairy tale, when the well-known sentence "And they lived happily ever after" shows up or is read at the end of the tale, children are taught a lesson in life, in real life.
In an article published by The Telegraph on June 29th, 2018, child psychologist Sally Goddard Blythe explains and justifies the importance of fairy tales. First, what seems to be a mere good guy/bad guy story to most children helps them feel safer and more receptive to accept daily lessons in life. These lessons can be about basic morality in the first place, but they will soon help the children build their capacity to learn from life, to dig deeper into morality and to discern good and evil.
In that perspective, as fairy tales are about imaginary worlds, children feel more comfortable to learn from them due to the fact that the plot is not about real life, events, or about something that is likely to happen to them. Tales are less scary than some novels or real life events they are confronted to in the news, for instance. In other words, imagination helps to accept reality, and this is not only true for children.
On top of that, as life is not always easy, reading about heroes and heroines' hardships and fights against wicked characters also shows, through fantasy and imaginary situations, that sometimes things go wrong, life can be hard, and some people play mischief and don't mean well.
Nevertheless, since most of the time the good guys are rewarded and the ending is a happy one, it reinforces the children's trust in adults and shows how important it is to be nice, courageous and honest.
